  • How can I programmatically link an UIView or UIImageView with an event like "touch up inside"?

    - by Thanks
    Interface Builder will only allow me to hook up such events for an button. But like in HTML, I just want to haven an blank UIImageView where - as soon as the user taps it - a method is invoked. I hope there is some cool programmatically way of doing that, which I don't know about. UPDATE: In my View Controller that creates the UIImageView I tried to do this: SEL actionSelector = @selector(doSomethingWhenImageIsTouched:); [self.myUIImageView addTarget:nil action:actionSelector forControlEvents:UIControlEventTouchUpInside]; The compiler gives me a warning, that UIImageView may not respond to addTarget:... what do I have to do so that it works with an UIImageView. I see in the docs that UIImageView does not inherit from UIControl, but addTarget: is part of UIControl. UPDATE: I ended up creating an UIButton after creating the UIImageView. Then I set the frame of that button to the frame of the UIImageView, and alpha to 0.1f. For some reason, it will not work if alpha is 0.0f. And then, I did that cool addTarget: thing...

  • Eclipse throwing error when copying and pasting

    - by hoffmandirt
    I am using Eclipse 3.5 SR2 for Java EE developers. Each time I press control+C or control+V for the first time after I open a file I get an error. After I close the error, I can successfully copy and paste. The error message made me believe that it was related to the Mylyn plugin, but I uninstalled it and still no difference. Has anyone else experience this problem? I also have the subclipse, adobe flex builder, and maven plugins installed. The 'org.eclipse.mylyn.tasks.ui.hyperlinks.detectors.url' extension from plug-in 'org.eclipse.mylyn.tasks.ui' to the 'org.eclipse.ui.workbench.texteditor.hyperlinkDetectors' extension point failed to load the hyperlink detector.

  • Running and managing NSTimer in different NSThread/NSRunLoop

    - by mips
    I'm writing a Cocoa application, with a GUI designed in Interface Builder. I need to schedule background activity (at regular intervals) without blocking the UI, so I run it in a separate thread, like this: - (void)applicationDidFinishLaunching:(NSNotification *)aNotification { [self performSelectorInBackground:@selector(schedule) withObject:nil]; } - (void) schedule { NSAutoreleasePool* pool = [[NSAutoreleasePool alloc] init]; NSRunLoop* runLoop = [NSRunLoop currentRunLoop]; timer = [[NSTimer scheduledTimerWithTimeInterval:FEED_UPDATE_INTERVAL target:activityObj selector:@selector(run:) userInfo:nil repeats:YES] retain]; [runLoop run]; [pool release]; } I retain the timer, so I can easily invalidate and reschedule. Problem: I must also fire the run: method in response to GUI events, so it is synchronous (i.e. a "perform activity" button). Like this: [timer fire]; I could do this with performSelectorInBackground too, and of course it doesn't block the UI. But this synchronous firings run in another runloop! So I have no guarantee that they won't overlap. How can I queue all of my firings on the same runloop?

  • Design Patterns Recommendation for Filtering Option

    - by Tarik
    Hi people, I am thinking to create a filter object which filters and delete everything like html tags from a context. But I want it to be independent which means the design pattern I can apply will help me to add more filters in the future without effecting the current codes. I thought Abstract Factory but it seems it ain't gonna work out the way I want. So maybe builder but it looks same. I don't know I am kinda confused, some one please recommend me a design pattern which can solve my problem but before that let me elaborate the problem a little bit. Lets say I have a class which has Description field or property what ever. And I need filters which remove the things I want from this Description property. So whenever I apply the filter I can add more filter in underlying tier. So instead of re-touching the Description field, I can easily add more filters and all the filters will run for Description field and delete whatever they are supposed to delete from the Description context. I hope I could describe my problem. I think some of you ran into the same situation before. Thanks in advance...

  • How can I create a custom UIToolbar like component in a UITableViewController?

    - by Tony
    I have a UITableViewController. I want a "toolbar-ish" component at the bottom. I started by using a background image and a button. In interface builder, I added them to the bottom of the iPhone screen. The problem I ran into was that the background image and button scrolled with the table. I obviously need this fixed at the bottom. Not finding too much direction online, I decided to customize a UIToolbar to look how I want since the position is fixed by default. In my initWithNibName for my UITableViewController, I have: UIImage *shuffleButtonImage = [UIImage imageNamed:@"shuffle_button.png"]; NSArray* toolbarItems = [NSArray arrayWithObjects: [[UIBarButtonItem alloc] initWithImage:shuffleButtonImage style:UIBarButtonItemStylePlain target:self action:@selector(push:)], nil]; [toolbarItems makeObjectsPerformSelector:@selector(release)]; self.toolbarItems = toolbarItems; The problem I am running into now is that the "shuffleButtonImage" is not showing up properly. The shape of the button shows up fine but it is colored white and therefore does not look like the image. Does anyone know why a "white image" would be showing instead of the actual image? Also does it sound like a good idea to customize a UIToolbar or is there a simple way to ensure a fixed position "toolbar-ish" component. To reiterate - my "toolbar-ish" component only needs to be one button at the button of my UITableView. The single button has a gradient color background that I create with an image.

  • iPhone SDK : UIImageView - Collapsing animation

    - by chris.o.
    Hi All, I'm trying to animating across the screen a horizontal bar with a color gradient. For simplicity, I chose to make a png of the fully extended bar, assign it to a UIImageView, and (attempt to) animate resizing of it using a UIView animation. The problem is that in the "closed" state of the Image, the portion of the image showing is not the part that I want. The image is arranged so that from L to R, a white to red color gradient occurs. The right side (about 20 pixels) is solid red and is the part I want to show when the bar is "collapsed". I'm trying to extend the image out by about 100 pixels to its full width. I referenced the "Buy Now" button example for my code as it seemed relevant" http://stackoverflow.com/questions/1669804/uibutton-appstore-buy-button-animation My code: [UIView beginAnimations:@"barAnimation" context:nil]; [UIView setAnimationDuration:0.6]; CGRect barFrame = bookBar.bounds; if (fExtendBar) { barFrame.origin.x -= 100; barFrame.size.width += 100; } else { barFrame.origin.x += 100; barFrame.size.width -= 100; } bookBar.frame = barFrame; [UIView commitAnimations]; I feel like this should be possible, maybe by setting an "offsetOfImage" to display in the UIImageView, but I can't seem to make it work. Also, I've noticed that the behavior is kind of consistent with what happens in Interface Builder when you resize an image. Then again, I would think there would be a way to override this behavior programmatically. Any suggestions (including other approaches) are welcome. Thanks, chris.o.

  • Process: Unable to start service com.google.android.gms.checkin.CheckinService with Intent

    - by AndyRoid
    I'm trying to build a Google map application but keep receiving this in my LogCat. I have all the permissions and meta-data set in my manifest, but am still dumbfounded by this error. Have looked everywhere on SO for this specific error but found nothing relating to com.google.android.gms.checkin A little bit about my structural hierarchy. MainActivity extends ActionBarActivity with three tabs underneath actionbar. Each tab has it's own fragment. On the gMapFragment I create a GPSTrack object from my GPSTrack class which extends Service and implements LocationListener. The problem is that when I start the application I get this message: I have all my libraries imported properly and I even added the google-play-services.jar into my libs folder.

  • Problem using Flash Components in multiple SWC files

    - by Ken Dunnington
    [Edit: Short version - how do you properly handle namespace collisions in SWC files if one SWC has fewer classes from that namespace than another?] I have a rather large Flash application which I'm building in Flash Builder (because coding/debugging in the Flash IDE is... not good) and I've got a ton of external SWC files which I'm linking in to my application. This has worked well so far - the file size is on the large side, but it's a lot simpler than loading in SWFs, especially since I am extending most of the classes in each SWC and adding custom code that way (it's a very design-heavy app.) The problem I'm having is when I have Flash Components, like ComboBox or TextInput, in more than one SWC. Whichever SWC was compiled last will work fine, but the others will fail with errors like the following: TypeError: Error #1034: Type Coercion failed: cannot convert flash.display::MovieClip@1f21adc1 to fl.controls.TextInput. at flash.display::Sprite/constructChildren() at flash.display::Sprite() at flash.display::MovieClip() at com.company.design.login::LoginForm() at com.company.view::Login()[/Users/ken/Workspace/src/com/company/view/Login.as:22] at com.company.view::Main/showLogin()[/Users/ken/Workspace/src/com/company/view/Main.as:209] at flash.events::EventDispatcher/dispatchEventFunction() at flash.events::EventDispatcher/dispatchEvent() at com.company.view::Navigation/handleUIClick()[/Users/ken/Workspace/src/com/company/view/Navigation.as:88] I've been researching components, ComponentShim, etc. but I'm running up against a brick wall. I thought it might be the fact that some of the components had their skins modified in the source FLA, so I tried replacing them with the default skins, but that didn't seem to help. How can I ensure that I have the components imported and available to all my classes, yet still be able to skin them and include them in my various FLAs? (I am never creating new instances of them, they are all laid out by my designer.)

  • How to make a UITextField move up when keyboard is present

    - by philfreo
    EDIT: Over 1k views with 3 upvotes? If this question is helpful, vote it up :) With the iPhone SDK: I have a UIView with UITextFields that brings up a keyboard. I need it to be able to: Allow scrolling of the contents of the UIScrollView to see the other text fields once the keyboard is brought up Automatically "jump" (by scrolling up) or shortening I know that I need a UIScrollView. I've tried changing the class of my UIView to a UIScrollView but I'm still unable to scroll the textboxes up or down. Do I need both a UIView and a UIScrollView? Does one go inside the other? [EDIT: I now know that you want a UIView inside of a UIScrollView, and the trick is to programatically set the content size of the UIScrollView to the frame size of the UIView.] Then what needs to be implemented in order to automatically scroll to the active text field? Ideally as much of the setup of the components as possible will be done in Interface Builder. I'd like to only write code for what needs it. Note: the UIView (or UIScrollView) that I'm working with is brought up by a tabbar (UITabBar), which needs to function as normal. Edit: I am adding the scroll bar just for when the keyboard comes up. Even though it's not needed, I feel like it provides a better interface because then the user can scroll and change textboxes, for example. I've got it working where I change the frame size of the UIScrollView when the keyboard goes up and down. I'm simply using: -(void)textFieldDidBeginEditing:(UITextField *)textField { //Keyboard becomes visible scrollView.frame = CGRectMake(scrollView.frame.origin.x, scrollView.frame.origin.y, scrollView.frame.size.width, scrollView.frame.size.height - 215 + 50); //resize } -(void)textFieldDidEndEditing:(UITextField *)textField { //keyboard will hide scrollView.frame = CGRectMake(scrollView.frame.origin.x, scrollView.frame.origin.y, scrollView.frame.size.width, scrollView.frame.size.height + 215 - 50); //resize } However this doesn't automatically "move up" or center the lower text fields in the visible area, which is what I would really like.

  • Flex HTMLLoader component not raising mouseDown events for all mouse clicks

    - by shane
    I have built a Air 2/Flex 4 kiosk application with Flash Builder 4. Currently I am implementing a touch screen browser to enable users to navigate company training videos. In an attempt to improve the usability of the website on the touchscreen I have placed the HTML component in an adaption of Doug McCune's DragScrollingCanvas (updated to use the flex 4 'Scroller' component) to allow users to scroll the webpage by dragging their finger across the screen. The mouseDown event is used to start scrolling the viewport. In addition the webpage was modified to disable text selection with the following css: html { -webkit-user-select: none; cursor: default; } The problem I face is that the HTMLLoader component only fires a mouseDown if a link/input/button on the webpage is clicked, not when the background or any text is clicked. In addition if I remove the custom css the mouseDown event will not fire when text is being selected, but will if previously highlighted text is clicked. As an alternative I also tried adding a group container with the same dimensions as the HTMLLoader to detect the mouseDown events (so that the group container and HTMLLoader have the same Dragable parent container) and was able to capture mouseDown events and scroll the viewport as expected. However as the mouse event is handled by the group container, I am now unable to navigate the webpage. Does anybody know why the HTMLLoader component is not raising mouseDown events for all mouse clicks?

  • Filter a wpf collectionviewsource in VB?

    - by Johnny Westlake
    Hi, I want to filter a collectionviewsource using a filter I've written, but I'm not sure how I can apply the filter to it? Here is my collection view source: <Grid.Resources> <CollectionViewSource x:Key="myCollectionView" Source="{Binding Path=Query4, Source={x:Static Application.Current}}"> <CollectionViewSource.SortDescriptions> <scm:SortDescription PropertyName="ContactID" Direction="Descending"/> </CollectionViewSource.SortDescriptions> </CollectionViewSource> </Grid.Resources> I have implemented a filter as such: Private Sub WorkerFilter(ByVal sender As Object, ByVal e As FilterEventArgs) Dim value As Object = CType(e.Item, System.Data.DataRow)("StaffSection") If (Not value Is Nothing) And (Not value Is DBNull.Value) Then If (value = "Builder") Or (value = "Office Staff") Then e.Accepted = True Else e.Accepted = False End If End If End Sub So how can I get the CollectionViewSource filtered by the filter on load? Could you please give all hte code I need (only a few lines I figure) as I'm quite new to coding. Thanks guys EDIT: For the record, <CollectionViewSource x:Key="myCollectionView" Filter="WorkerFilter" ... /> gives me the error: Failed object initialization (ISupportInitialize.EndInit). 'System.Windows.Data.BindingListCollectionView' view does not support filtering. Error at object 'myCollectionView'

  • How Can i reload data in tableview in view controller in iphone

    - by Pugal Devan
    Hi, I am new to iphone development. I have created 5 buttons in the view. On clicking the buttons it navigates to the corresponding views. On clicking the "News" button it navigates and displayed the parsing details in the table view.(This table view, I have created View controller and added table view using Interface Builder and i have set all the properties.) and i go to another button and comes back to the "News" button, every time parsing will happened.How to avoid the multiple parsing when i come back to the button. i have tried this one and my code is, - (void)viewDidAppear:(BOOL)animated { [super viewDidAppear:animated]; static int i; if(i == 0) { NSString * path = @"http://www.AAAAAAAAAAAAAAAA.com"; [self parseXMLFileAtURL:path]; i++; } [self.newsTable reloadData]; } } Now the parsing is happened only time but the datas are doesnt displayed. My problem is the tableview doesnot reload. newsTable is the instance of the Tableview. How can i achieve this. Please help me out. Thanks.

  • Adding a navigation bar to a web view in a tab bar app

    - by Henrik Erlandsson
    I've built the tab bar application in IB, with three tabs. The third tab happily displays a UIWebview where you can browse. The only thing missing is a back button, as not all web pages supply such a link. I need a navigation bar hooked up properly to the correct classes. I'm still a bit unsure about exactly how the hierarchy should look in interface builder and how to hook it up properly. Currently, the third tab is hooked up to a referencing outlet called 'webnews' in the class 'thirdviewcontroller', and the UIWebView (under a normal IUView in the hierarchy, which in turn is under the third tab bar controller) is connected to the webnews outlet. How do I make the navbar control the webview, and do I add code to the thirdviewcontroller.m that lets the navbar on the view control the webview 'back' function? What do I hook up as the delegate for it? Currently I have an app delegate, but that's hooked up to the tab bar. I'm not really after specific code as much as a general 'how it works' clue :) (Unless I can just add the navbar dynamically to the functioning app... but I don't think addSubView on viewWillAppear {} in thirdviewcontroller.m will create the proper functionality?) If I were to guess at the simplest solution, I'd guess create a navbarcontroller.h/.m, slap a navbar on the view in IB, connect the third tab to navbarcontroller, connect the navbar to the webview (?) and move the webnews outlet to navbarcontroller.h, and connect the webview to it. But I don't quite have the nerve to try, better to ask advice first.

  • adding tabbar to uiview (not tabbarcontroller) to switch views

    - by Pavan
    Hi, i added a Tab bar to my existing view called secondViewController where there are now 4 tab bar items using interface builder. This tab bar will allow the users to switch between views. This is what ive tried to do: If i use a tabbar controller, then a new view pops up and i dont want that. i simply want to be able to add a tab bar as ive done and carry on from there. i dont know how to actually connect it all up and make everything work together. This is what i understand: i have to make my current - secondViewController an tabbardelegate which is what ive done as shown @interface paddedDholViewController : UIViewController <AVAudioPlayerDelegate, UITabBarDelegate> { } then i understand that i have to add tabBar.delegate = self; for me to be able to detect the tabBar:didSelectItem: so i can then implement something like this - (void)tabBarController:(UITabBarController *)tabBarController didSelectViewController:(UIViewController *)viewController { if ([viewController.tabBarItem.title isEqualToString:@"FIRST"]) { NSLog(@"FIRST"); } else if ([viewController.tabBarItem.title isEqualToString:@"SECOND"]) { NSLog(@"SECOND"); } } to be able to switch between the views The thing is as ive said before i dont know how to implement all of this and how to connect everything up. can someone help me please. Thank you in advance

  • Is there more to HTML forms than http://www.w3schools.com/html/html_forms.asp ?

    - by mawg
    I am creating a form designer. It will generate PHP code which will produce an HTML form. Users will fill in fields and the PHP will store user input in a MySql database (and, of course, they can use the designer to generate forms which query the database). I am using Borland C++ Builder (very similar to Delphi & and you can get the same idea from VB, MSVC, Qt ... any IDE with a RAD GUI designer). Looking at the W3C page http://www.w3schools.com/html/html_forms.asp it seems that the components I can use for my form and retrieve data from are - edit box / TEdit / <input type="text" - memo / TMemo / <input type="textarea" - check box / TCheckBox / <input type="CheckBox" - Combo box / TComboBox / <select ... <option... - Radio group / TRadioGroup / <input type="radio" - Group box / TGroupBox / <fieldset ... <legend ... - Panel / TPanel / <fieldset ... I am unsure whether to allow button / TButton/ input type="button" - other than a single submit button which my form designer program automatically adds to the end of the generated form. But my real question is - did I miss any? It might be nice to have masked edit which only accepts numbers, or maybe some form of "spin control" (TUpDown, or slider + linked read only TEdit), so that the user can click & hold to increment/decrement an integer value. And a calendar component would be nice. Very important: I want to implement it all server-side in PHP, so no client-side JS or Ajax or the likes. If there anything else that I can add to make my generated forms look more impressive in the browser?

  • Designing a fluid Javascript interface to abstract away the asynchronous nature of AJAX

    - by Anurag
    How would I design an API to hide the asynchronous nature of AJAX and HTTP requests, or basically delay it to provide a fluid interface. To show an example from Twitter's new Anywhere API: // get @ded's first 20 statuses, filter only the tweets that // mention photography, and render each into an HTML element T.User.find('ded').timeline().first(20).filter(filterer).each(function(status) { $('div#tweets').append('<p>' + status.text + '</p>'); }); function filterer(status) { return status.text.match(/photography/); } vs this (asynchronous nature of each call is clearly visible) T.User.find('ded', function(user) { user.timeline(function(statuses) { statuses.first(20).filter(filterer).each(function(status) { $('div#tweets').append('<p>' + status.text + '</p>'); }); }); }); It finds the user, gets their tweet timeline, filters only the first 20 tweets, applies a custom filter, and ultimately uses the callback function to process each tweet. I am guessing that a well designed API like this should work like a query builder (think ORMs) where each function call builds the query (HTTP URL in this case), until it hits a looping function such as each/map/etc., the HTTP call is made and the passed in function becomes the callback. An easy development route would be to make each AJAX call synchronous, but that's probably not the best solution. I am interested in figuring out a way to make it asynchronous, and still hide the asynchronous nature of AJAX.

  • Update table columns bound to NSArrayController

    - by Loz
    Hi, I'm fairly new to the world of bindings in cocoa, and I'm having some troubles (perhaps/probably due to a misunderstanding). I have a singleton that contains an NSMutableArray called plugins, containing objects of class Plugin. It has a method called loadPlugins which adds objects to the plugins array. This may be called at any point. It's been added as an instance in Interface Builder. Also in IB is an NSObjectController, whose content outlet is connected to the singleton. There is also an NSArrayController, whose contentArray is bound to the NSObjectController (controller key is 'selection', model key path is 'plugins', object class name is 'Plugin'). And finally I have a table view with 2 columns, the values of which are bound to the NSArrayController's arrangedObjects, using keys of properties in the Plugin class. So far so standard (as far as I can tell from tutorials at least). My trouble is that when the loadPlugins method is called in the singleton, and objects are added to the plugins array, the table doesn't update to show the objects (unless loadPlugins is called before the nib is loaded). -reloadData called on the tableView doesn't do anything. Is there a way to tell the NSArrayController that the referenced array has been updated? I understand there is the -add: method for NSArrayController, which could be used in the loadPlugins, but this isn't desirable as I want to keep the singleton totally separate from the display aspect. This seems related to: http://stackoverflow.com/questions/1623396/refresh-cocoa-binding-nsarraycontroller-combobox The line: "editing the array behind the controller's back" seems to perhaps pinpoint the problem, but I would hope that it would be possible to have the singleton not know about the controller. Thanks in advance.

  • HTTPService/ResultEvent with Flex 3.2 versus Flex >= 3.5

    - by Julian
    Hey everybody, through a design decission or what-so-ever Adobe changed the content of the ResultEvent fired by a HTTPService Object. Take a look at following example: var httpService:HTTPService = myHTTPServices.getResults(); httpService.addEventListener(ResultEvent.RESULT,resultHandler); httpService.send(); /** * Handels the login process */ function resultHandler(event:ResultEvent):void { // get http service var httpService = (event.target as HTTPService); // do something } It works like a charm with Flex 3.2. But when I try to compile it with Flex 3.5 or Flex 4.0 event.target as HTTPService is null. I figured out that event.target is now an instance of HTTPOperation. That is interesting because I can't find HTTPOperation in the langref. However, I think what Flash Builder's debugger means is mx.rpc.http.Operation. The debugger also shows that event.target has a private attribute httpService which is the instance I expected to get with event.target. But it's private, so event.target.httpService doesn't work. If I only want to remove the EventListener I can cast event.target as EventDispatcher. But I need to use methods from HTTPService. So: How can I get the HTTPService instance from the ResultEvent? Any help would be appreciated. Thanks! J.

  • weak or strong for IBOutlet and other

    - by Piero
    I have switched my project to ARC, and I don't understand if I have to use strong or weak for IBOutlets. Xcode do this: in interface builder, if a create a UILabel for example and I connect it with assistant editor to my ViewController, it create this: @property (nonatomic, strong) UILabel *aLabel; It uses the strong, instead I read a tutorial on RayWenderlich website that say this: But for these two particular properties I have other plans. Instead of strong, we will declare them as weak. @property (nonatomic, weak) IBOutlet UITableView *tableView; @property (nonatomic, weak) IBOutlet UISearchBar *searchBar; Weak is the recommended relationship for all outlet properties. These view objects are already part of the view controller’s view hierarchy and don’t need to be retained elsewhere. The big advantage of declaring your outlets weak is that it saves you time writing the viewDidUnload method. Currently our viewDidUnload looks like this: - (void)viewDidUnload { [super viewDidUnload]; self.tableView = nil; self.searchBar = nil; soundEffect = nil; } You can now simplify it to the following: - (void)viewDidUnload { [super viewDidUnload]; soundEffect = nil; } So use weak, instead of the strong, and remove the set to nil in the videDidUnload, instead Xcode use the strong, and use the self... = nil in the viewDidUnload. My question is: when do I have to use strong, and when weak? I want also use for deployment target iOS 4, so when do I have to use the unsafe_unretain? Anyone can help to explain me well with a small tutorial, when use strong, weak and unsafe_unretain with ARC?

  • How do I underline parent menu item but not children?

    - by Steven
    Using Wordpress menu "builder", I get the following code: //Pseaudo code <ul id="main-menu-main"> <li class="menu-item"><a></a></li> <li class="menu-item current-menu-ancestor"> <a></a> <ul class="sub-menu"> <li class="menu-item"><a></a></li> <li class="menu-item current-menu-item"><a></a></li> </ul> </li> </ul> // and I use the following CSS #menu-main-menu a:hover { text-decoration: underline; } #menu-main-menu .current-menu-ancestor a { text-decoration: underline; } The problem with my last css line, is that all a elements under current-menu-ancestor are underlined. I only want the link in current-menu-ancestor to be underlined. I think this should be pretty simple, but right now my head is not focused :-/ The full code for parent / child looks like this: <ul id="menu-main-menu" class="menu"> <li id="menu-item-401" class="menu-item-first menu-item menu-item-type-post_type menu-item-object-page current-page-ancestor current-menu-ancestor current-menu-parent current-page-parent current_page_parent current_page_ancestor menu-item-401"> <a>menu 1</a> <ul class="sub-menu"> <li id="menu-item-444" class="menu-item menu-item-type-post_type menu-item-object-page current-menu-item page_item page-item-415 current_page_item menu-item-444"> <a> sub 1</a> </li> </ul> </li>

  • touchesBegin & touchesMove Xcode Obj C Question

    - by AndrewDK
    So I have my app working good when you press and drag along. I also have UIButtons set to Touch Down in Interface Builder. As well when you drag you need to drag from the outside of the UIButton. You cannot click on the UIButton and drag to the other. TOUCHES MOVED: Code: -(void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event { UITouch *touch = [[event touchesForView:self.view] anyObject]; CGPoint location = [touch locationInView:touch.view]; if(CGRectContainsPoint(oneButton.frame, location)) { if (!oneButton.isHighlighted){ [self oneFunction]; [oneButton setHighlighted:YES]; } }else { [oneButton setHighlighted:NO]; } // if(CGRectContainsPoint(twoButton.frame, location)) { if (!twoButton.isHighlighted){ [self twoFunction]; [twoButton setHighlighted:YES]; } }else { [twoButton setHighlighted:NO]; } } TOUCHES BEGAN: Code: - (void) touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { UITouch *touch = [[event touchesForView:self.view] anyObject]; CGPoint location = [touch locationInView:touch.view]; if(CGRectContainsPoint(oneButton.frame, location)) { [self oneFunction]; [oneButton setHighlighted:YES]; } if(CGRectContainsPoint(twoButton.frame, location)) { [self twoFunction]; [twoButton setHighlighted:YES]; } } I want to be able to click on any of the button fire the function & also be able to drag from one button on to the other and fire that function. So basically just being able to click on a button and slide your finger over and activate the other button without having to press and slide from outside of the button. I think I'm close, need a bit of help. Hope thats clear enough. Thanks.

  • Flash video slooow in AIR 2 HTMLLoader component

    - by shane
    I am working on a full screen kiosk application in Flex 4/Air 2 using Flash Builder 4. We have a company training website which staff can access via the kiosk, and the main content is interactive flash training videos. Our target machines are by no means 'beefy', they are Atom n270s @ 1.6Ghz with 1Gb RAM. As it stands the videos are all but unusable when used from within the Air application, the application becomes completely unresponsive (100% cpu usage, click events take approx 5-10 seconds to register). So far I have tried: increasing the default frame rate from 24fps to 60. No improvement. nativeWindow.stage.frameRate = 60; running the videos in a stripped down version of my app, just a full screen HTMLLoader component pointed at the training website. No better than before. disabled hyper threading. The Atom CPU is split into two virtual cores, and the AIR app was only able to use one thread so maxed out at 50% CPU usage. Since the kiosk will only run the AIR app I am happy to loose hyper threading to increase the performance of the Air app. Marginal Improvement. The same website with the same videos is responsive if viewed in ie7 on the same machine, although Internet Explorer takes advantage of the CPU’s hyper threading. The flash videos are built with Adobe Captivate and from what I understand employee JavaScript to relay results back to the server. I will add more information about the video content asap as the training guru is back in the office later this week.

  • Why Does the iPad Main View Refuse to go FullScreen?

    - by dugla
    I am doing an imaging app for iPad and it requires use of the entire screen. The approach I have used on iPhone does not appear to work on iPad. In Interface Builder I have set the UIToolbar to translucent.This code echos the dimensions of the main view before and after requesting fullscreen. (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { [self.window addSubview:self.viewController.view]; NSLog(@"Hello Popover AD - application did Finish Launching With Options - viewSize: %f %f BEFORE", self.viewController.view.bounds.size.width, self.viewController.view.bounds.size.height); [self.viewController setWantsFullScreenLayout:YES]; [self.viewController.view layoutIfNeeded]; NSLog(@"Hello Popover AD - application did Finish Launching With Options - viewSize: %f %f AFTER", self.viewController.view.bounds.size.width, self.viewController.view.bounds.size.height); [self.window makeKeyAndVisible]; return YES; } This is what NSlog has to say: Hello Popover AD - application did Finish Launching With Options - viewSize: 768 1004 BEFORE Hello Popover AD - application did Finish Launching With Options - viewSize: 768 1004 AFTER Can someone please tell me what I am doing incorrectly here? Note, on iPhone I set fullscreen within the init method of the relevant ViewController. Can view resizing only be done in a ViewController? My ultimate goal is a fullscreen view nicely tucked underneath a translucent status bar and tool bar. I will retract the status/tool bars when user interaction begins in the main view. Thanks, Doug

  • template engine implementation

    - by qwerty
    I am currently building this small template engine. It takes a string containing the template in parameter, and a dictionary of "tags,values" to fill in the template. In the engine, I have no idea of the tags that will be in the template and the ones that won't. I am currently iterating (foreach) on the dictionnary, parsing my string that I have put in a string builder, and replacing the tags in the template by their corresponding value. Is there a more efficient/convenient way of doing this? I know the main drawback here is that the stringbuilder is parsed everytime entirely for each tag, which is quite bad... (I am also checking, though not included in the sample, after the process that my template does not contain any tag anymore. They are all formated in the same way: @@tag@@) //Dictionary<string, string> tagsValueCorrespondence; //string template; StringBuilder outputBuilder = new StringBuilder(template); foreach (string tag in tagsValueCorrespondence.Keys) { outputBuilder.Replace(tag, tagsValueCorrespondence[tag]); } template = outputBuilder.ToString(); Responses: @Marc: string template = "Some @@foobar@@ text in a @@bar@@ template"; StringDictionary data = new StringDictionary(); data.Add("foo", "value1"); data.Add("bar", "value2"); data.Add("foo2bar", "value3"); Output: "Some text in a value2 template" instead of: "Some @@foobar@@ text in a value2 template"
