• Add icon on spark button skin

  - by Jerry

  Hello all I am trying to add different icon on different buttons. I have my skin file ready but not sure if I have to create different skin class for different button. It sounds inefficient. Any suggestions?

• Calling blockUI and unblockUI in combination with jQuery validator plugin

  - by Tim Stewart

  I have a very complex form with the validation working correctly. However, since it can take awhile for the validation to complete, I'd like to use blockUI to be called when I click the form's submit button to prevent confusion and double-submissions. I can't quite figure out how to do this. My code looks like this: $("#credential").validate({ rules: { EngId: { required: true } ClientAccount: { required: true } ... } and I'm calling the validation with several buttons (using their click function) depending on selections in the form, often disabling some of the rules: $("#buttonname").click(function() { $("#fieldname").rules("remove"); ... $("#credential").submit(); }); What I can't figure out is where the blockui and unblockui calls would go so that when the user clicks the button, before validation starts, blockui does its magic, and if the validation finds a problem, unblockui is called and enables the form again. I'm pretty new to Jquery and I can't find any examples that I've been able to implement successfully. I would appreciate any help anyone could give (please excuse if this has been covered before).

• Nested Linear layout only shows first view after being set from gone to visible in Android

  - by Adam

  Hi guys, I am developing an Android app but I'm still pretty new. I want to have a button, and when you push that button, a few TextViews and Buttons will appear. So I have a main linear layout, and then another linear layout nested inside containing the things I want hidden. I have the nested linear layout set to android:visibility="gone". The problem I am having is that it only shows the first item inside the hidden linear layout instead of all of them. The way I try to make it appear is vgAddView = (ViewGroup)findViewById(R.id.add_details); btnAche.setOnClickListener(new OnClickListener(){ public void onClick(View v){ vgAddView.setVisibility(0); } }); My XML file is this <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" > <Button android:text="@string/but_stomach_ache" android:id="@+id/but_stomach_ache" android:layout_width="fill_parent" android:layout_height="wrap_content"> </Button> <Button android:text="@string/but_food" android:id="@+id/but_food" android:layout_width="fill_parent" android:layout_height="wrap_content"> </Button> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" android:id="@+id/add_details" android:visibility="gone"> <TextView android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" android:text="@string/when_happen"> </TextView> <Button android:text="@string/happen_now" android:id="@+id/happen_now" android:layout_width="fill_parent" android:layout_height="wrap_content"> </Button> </LinearLayout> </LinearLayout>

• UISearchDisplayController not working when created in code??

  - by Nick Bedford

  I'm working on a tab bar application and one of the tabs has a UISearchDisplayController hooked up to a UISearchBar. It's all connected up in the NIB and is working. When I tap the search bar, the Scope and Cancel buttons fly in etc, and the search delegate updates the results table correctly. However, I'm trying to implement the same code in the viewDidLoad message instead of the NIB, however when I delete the search display controller from the NIB and uncomment my code to create the same controller in the function, it doesn't work. It's as if there's some fundamental connection not being made so that all my search delegate functionality isn't being called. Here's my working NIB version of the Search Display Controller. It's hooked up to the search bar, the UINavigationController subclass (MASearchController) and the root view of that is hooked up as the searchContentsController. Now this is what you would expect to do in code to create the same, right? What I'm doing is leaving the UISearchBar in the NIB to eliminate one piece of the puzzle at a time in code. // [MASearchController viewDidLoad] UISearchDisplayController *searchController = [[[UISearchDisplayController alloc] initWithSearchBar:searchBar contentsController:[[self viewControllers] objectAtIndex:0]] autorelease]; [searchController setDelegate:self]; [searchController setSearchResultsDelegate:self]; [searchController setSearchResultsDataSource:self]; I've checked all objects at run time and they all check out. Essentially I've deleted the search display controller from the NIB and then put in the code to create it in the viewDidLoad message. Why would this not work? The search keyboard comes up but none of my search and button animation functionality work???

• Automatically support new changes with Python.

  - by Zachary Brown

  I was working on a program,that I need to support new additions. Hmmm. Let me give you some background on the program. It is an educational software program that has quizzes for the user to take, just to gain odd knowledge. Now, It currently supports 6 subjects, all organized with directores on the HDD ( i.e. the Science directory is called science. ) and the way you launch the subject to see what quizzes you have to take is by pushing a button on the home screen. This sort of thing prevents easy subject additions. I want to be able to add a subject later on without having to recode the home screen and re organize all the buttons. I would use a Listbox and os.listdir(...), but I was kind of wanting something prettier than a Listbox. I am using Tkinter on Windows. The Python version I am using is 2.6 Is there a "fancy" listbox sort of thing that can be styled to work with the background?

• a floating toolbar in WTL

  - by freefallr

  I've created a multimedia app that uses DirectShow to display multiple media streams simultaneously. The app is a WTL MDI application. For video windows, I use a CWindowImpl derived class - one per CChildFrame. I'd like to add controls to the video windows (volume ctrls etc). I'd initially thought about adding a slider (volume) control and a couple of buttons to a context menu - but later thought that this might not be the best approach. I was looking at MS Word 2007 - which has a floating toolbar that allows you to change options on highlighted text. I'd like to implement a similar floating toolbar for the video controls. I googled around a bit and found an old post about floating toolbars in WTL. The response was - for a floating toolbar, create a popup window and make it's parent the main window. I think that this sounds like a reasonable approach. my questions: Is this a good approach, or is there a more standard approach for a floating toolbar now in WTL? Should I make the toolbar a child of the video window or the CChildFrame that contains the video window, in order to ensure that it always remains on top of the video? How can I implement transparency in the floating toolbar, as in the floating toolbar in MS word?

• custom view on iphone's native media player(MPMoviePlayerController)

  - by sneha

  I am building an application that implements a custom view on iPhone’s native media player. I want your help in deciding directions to lay this effort. At present I have find out that iPhone SDK doesn’t support APIs to customize media player. I need these things in the player: I would like to have custom views i.e. want to change all control buttons on player like Play/Pause, seek bar etc. The background of player will also need to be different. The player has to play audio or video file from local/remote location. Can i use MPMoviePlayerController if it can be customized (How to do it ??). However, any other third party player approved by iPhone which has an ability to download and play the media file from local/remote location is also fine. It will be great to have an access to media player buffer so that it can be encrypted. I have following questions: 1.Any help in building/customizing player..... 2.Do you see issues in signing of application? 3.Does Apple have any restrictions on customizing media player? 4.Any sample iPhone application where media player is customized Any help in this regard is highly appreciated.

• JavaScript To Clear Form Field On Submit Before Form Submission To Perl Script

  - by Russell C.

  We have a very long form that has a number of fields and 2 different submit buttons. When a user clicks the 1st submit button ("Photo Search") the form should POST and our script will do a search for matching photos based on what the user entered in the text input ("photo_search_text") next to the 1st submit button and reload the entire form with matching photos added to the form. Upon clicking the 2nd submit button ("Save Changes") at the end of the form, it should POST and our script should update the database with the information the user entered in the form. Unfortunately the layout of the form makes it impossible to separate it into 2 separate forms. I checked the entire form POST and unfortunately the submitted fields are identical to the perl script processing the form submission no matter which submit button is clicked so the perl script can't differentiate which action to perform based on which submit button is pushed. The only thing I can think of is to update the onclick action of the 2nd submit button so it clears the "photo_search_text" field before the form is submitted and then only perform a photo search if that fields has a value. Based on all this, my question is what does the JavaScript look that could clear out the "photo_search_text" field when someone clicks on the 2nd submit button? Here is what I've tried so far none of which has worked successfully: <input type="submit" name="submit" onclick="document.update-form.photo_search_text.value='';" value="Save Changes"> <input type="submit" name="submit" onsubmit="document.update-form.photo_search_text.value='';" value="Save Changes"> <input type="submit" name="submit" onclick="document.getElementById('photo_search_text')='';" value="Save Changes"> We also use JQuery on the site so if there is a way to do this with jQuery instead of plain JavaScript feel free to provide example code for that instead. Lastly, if there is another way to handle this that I'm not thinking of any and all suggestions would be welcome. Thanks in advance for your help!

• Selecting a Java framework for large application w/ only ONE user

  - by Bijan

  I am building a large application that will be hosted on an AWS server. I'm trying to select a web framework for assisting me with code organization, template design, and generally presentation aspects. Here are some points of consideration: Require security/login/user authentication. I may add the ability in the future to allow more than just an administrator to access the web app, but it is not a public facing website. AJAX support would be helpful. There are a couple widgets that I don't want to recreate. One is a tree object, where the user can expand/contract items in the list, can create new branches, add/edit objects. This would be better off in some dynamic view rather than all done in ugly html. Generally, this is just to provide the application with a face for control, management, and monitoring. Having an easier time adding buttons, CSS, AJAX widgets are great additions though, but not the primary purpose. I'm considering: Wicket Spring Seam GWT Stripe and the list goes on, as I'm sure you all know. I originally planned on using GWT, but then started to feel that GWT didn't cover my primary needs. I could be wrong about this, but there seems to be a lot of support for GWT AND Wicket/Spring. All of this 'getting lost in java frameworks' got me thinking outside the java realm for a framework that would suit my needs that was a clear option, like: JRuby/Rails Jython/Django Groovy/Grails Guice (just throwing this in there... I don't clearly understand the main purposes of all these frameworks. It doesn't seem like DInjection is something I need for a single purpose application) Thanks as always. This community makes Googling for esoteric programming information an order of magnitude better.

• What is the right way to scale a Flex application up to fullscreen?

  - by Impirator

  Fullscreen mode and I have been battling for a while in this Flex application, and I'm coming up short on Google results to end my woes. I have no problem going into fullscreen mode by doing a Application.application.stage.displayState = StageDisplayState.FULL_SCREEN;, but the rest of the content just sits there in the top, left corner at it's original size. All right, says I, I'll just do a stage.scaleMode = StageScaleMode.SHOW_ALL and make it figure out how to pull this off. And it looks like it does. Except that when you mouse over the individual checkboxes and buttons and various components, they all fidget slightly. Just a slight jump up or down as they resize...on mouse over. Well, this is frustrating, but bearable. I can always just invoke invalidateSize() explicitly for all of them. But for the comboboxes. The ones at the bottom have their menus go off the bottom of the screen, and when I pop out of fullscreen mode, their drop downs cut off half way. I have no idea how to fix that. Can someone step in here, and put me out of my misery? What is the right way to scale a Flex application up to fullscreen? var button:Button = button_fullscreen; try { if(stage.displayState == StageDisplayState.FULL_SCREEN) { Application.application.stage.displayState = StageDisplayState.NORMAL; button.label = "View Fullscreen Mode"; stage.scaleMode = StageScaleMode.NO_SCALE; } else { Application.application.stage.displayState = StageDisplayState.FULL_SCREEN; button.label = "Exit Fullscreen Mode"; stage.scaleMode = StageScaleMode.SHOW_ALL; } invalidateSizes(); // Calls invalidateSize() explicitly on several components. } catch(error:SecurityError) { Alert.show("The security settings of your computer prevent this from being displayed in fullscreen.","Error: "+error.name+" #"+error.errorID); } catch(error:Error) { Alert.show(error.message,error.name+" #"+error.errorID); }

• calling Valums Ajax uploader from other DOM element

  - by Marc

  I'm facing a problem with the valums Ajax File upload. Since the plugin is working perfectly after a few modifications on the server side, I cannot implement a specific behavior. My DOM is composed with an input file plus the container to instantiate the fileuploader buttons. What I want is to be able to fire the fileuploader plugins when clicking on the input:file[name="upload-file"]. ... <div id="upload-accepted"> <fieldset> <label for="upload-file">Select a file:</label> <input type="file" name="upload-file" id="upload-file"/> <noscript> <p>Please enable JavaScript to use file uploader.</p> </noscript> </fieldset> <div id="upload-container"> </div> </div> ... <script type="text/javascript"> $(function() { var uploader = new qq.FileUploader({ action: '/file-upload', element: document.getElementById('upload-container'), onSubmit: function(id, filename){...}, onComplete: function(id, fileName, responseJSON){...} }); }); </script> I have tried to add the following on the script but it don't works $("#upload-file").live('change', function(event) { event.preventDefault(); $('.qq-upload-button').trigger('click'); return false; }); Any clues?

• SQL Server 2008 Express Edition Connection Problem

  - by waqasahmed

  I have VS 2008 Professional Edition. After the installation (which included SQL Server 2008), I decided to install SQL Server 2008 Express Edition with Advanced Tools (so I could get SQL Server Management Studio on it). So I uninstalled the SQL Express that came with VS 2008, and installed the standalone SQL Server Express 2008 version with advanced tools. However, When I try to logon onto SQL Server Management Studio using: .\SQLEXPRESS as Server name and Windows Authentication as the authentication, I get the following message: TITLE: Connect to Server ------------------------------ Cannot connect to .\SQLEXPRESS. ------------------------------ ADDITIONAL INFORMATION: A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections.

• How can I disable the CTRL-ALT-DEL key combination completely on XP/Vista/7?

  - by Travesty3

  I have been googling extensively to figure this out, and nobody seems to be able to give a direct answer. Let me start by saying that I'm NOT talking about requiring CTRL-ALT-DEL to enter logon information. I'm working on a golf simulator program which is used at golf centers. I need the ability to completely disable the CTRL-ALT-DEL key sequence so that the golf center customers can't get out of the program and access the computer at all. I realize there are other key combinations that need to be handled as well, we already have this entire feature working in XP, but we're going to be switching to Windows 7 soon, and CTRL-ALT-DEL is the only one that doesn't seem to work in Win7. I'd really like an all-around solution if at all possible. This same program may also be installed on a client's personal computer for an in-home golf simulator, but the computers that really need this feature (golf center computers) are provided to the golf center by us, so would the best option be to write a new shell? I don't know anything about that at all, other than others that suggest writing a new shell for kiosk mode. I'd really like a simpler option, like modifying the registry in some way. I have heard that you can remove some buttons from the menu screen that pops up, but unless I can remove pretty much all of them (including the shutdown/restart button in the bottom-right corner), this won't be enough of a solution for me. Thanks for taking the time to read this and thanks again for any help you could provide! -Travis

• ASP.NET MVC 2: Mechanics behind an Order / Order Line in a edit form

  - by Dr. Zim

  In this question I am looking for links/code to handle an IList<OrderLine> in an MVC 2 edit form. Specifically I am interested in sending a complete order to the client, then posting the edited order back to an object (to persist) using: Html.EditorFor(m = m.orderlines[i]) (where orderlines is an enumerable object) Editing an Order that has multiple order lines (two tables, Order and OrderLine, one to many) is apparently difficult. Is there any links/examples/patterns out there to advise how to create this form that edits an entity and related entities in a single form (in C# MVC 2)? The IList is really throwing me for a loop. Should I have it there (while still having one form to edit one order)? How could you use the server side factory to create a blank OrderLine in the form while not posting the entire form back to the server? I am hoping we don't treat the individual order lines with individual save buttons, deletes, etc. (for example, they may open an order, delete all the lines, then click cancel, which shouldn't have altered the order itself in either the repository nor the database. Example classes: public class ViewModel { public Order order {get;set;} // Only one order } public class Order { public int ID {get;set;} // Order Identity public string name {get;set;} public IList<OrderLine> orderlines {get;set;} // Order has multiple lines } public class OrderLine { public int orderID {get;set;} // references Order ID above public int orderLineID {get;set;} // Order Line identity (need?) public Product refProduct {get;set;} // Product value object public int quantity {get;set;} // How many we want public double price {get;set;} // Current sale price }

• Adding BarButtons to a UINavigationBar after presenting a modal view controller.

  - by yujean

  I'm using the template for a "Utility Application". In the "FlipSideViewController", I added an IBOutlet for a UINavigationController, navController. In the code, I added the navController just fine. The rootViewController loads perfectly: navController.viewControllers = [[NSArray arrayWithObject:rootViewController] retain]; [self.view addSubview:navController.view]; I changed the color of the navController just fine: navController.navigationBar.tintColor = [UIColor colorWithRed:0.6 green:0.75 blue:0.6 alpha:1.0]; navController.navigationBar.translucent = NO; I make a button (note: "done" refers to a IBAction that dismisses the modalviewcontroller): UIBarButtonItem *backButton = [[UIBarButtonItem alloc] initWithTitle:@"TEST" style:UIBarButtonItemStyleDone target:self action:@selector(done:)]; I make a navItem using that button: UINavigationItem *backNavItem = [[UINavigationItem alloc] initWithTitle:@"TESTTEST"]; [backNavItem setRightBarButtonItem:backButton animated:YES]; I try to add that button: [navController.navigationBar pushNavigationItem:backNavItem animated:YES]; This above code fails miserably. I apparently can't add buttons to the navController because: * Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Cannot call pushNavigationItem:animated: directly on a UINavigationBar managed by a controller.' Do I have to make a separate UINavigationBar that's somehow connected to my navController? I tried going that route but with no avail.

• MFMailComposeViewController hangs my app

  - by Neal L

  Hi, I am trying to add email functionality to my app. I can get the MFMailComposeViewController to display correctly and pre-populate its subject and body, but for some reason when the user clicks on the "Cancel" or "Send" buttons in the nav bar the app just hangs. I inserted a NSLog() statement into the first line of mailComposeController"didFinishWithResult:error and it doesn't even print that line out to the console. Does anybody have an idea what would cause the MFMailComposeViewController to hang like that? Here is my code from the header: #import "ManagedObjectEditor.h" #import <MessageUI/MessageUI.h> @interface MyManagedObjectEditor : ManagedObjectEditor <MFMailComposeViewControllerDelegate, UIImagePickerControllerDelegate, UINavigationControllerDelegate> { } - (IBAction)emailObject; @end from the implementation file: if ([MFMailComposeViewController canSendMail]) { MFMailComposeViewController *mailComposer = [[MFMailComposeViewController alloc] init]; mailComposer.delegate = self; [mailComposer setSubject:NSLocalizedString(@"An email from me", @"An email from me")]; [mailComposer setMessageBody:emailString isHTML:YES]; [self presentModalViewController:mailComposer animated:YES]; [mailComposer release]; } [error release]; [emailString release]; and here is the code from the callback: #pragma mark - #pragma mark Mail Compose Delegate Methods - (void)mailComposeController:(MFMailComposeViewController *)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError *)error { NSLog(@"in didFinishWithResult:"); switch (result) { case MFMailComposeResultCancelled: NSLog(@"cancelled"); break; case MFMailComposeResultSaved: NSLog(@"saved"); break; case MFMailComposeResultSent: NSLog(@"sent"); break; case MFMailComposeResultFailed: { UIAlertView *alert = [[UIAlertView alloc] initWithTitle:NSLocalizedString(@"Error sending email!",@"Error sending email!") message:[error localizedDescription] delegate:nil cancelButtonTitle:NSLocalizedString(@"Bummer",@"Bummer") otherButtonTitles:nil]; [alert show]; [alert release]; break; } default: break; } [self dismissModalViewControllerAnimated:YES]; } Thanks!

• Changing JButton background colour temporarily?

  - by sashep

  Hi, I'm super new to Java, and in need of some help. I'm making a little java desktop application where I basically have a grid of 4 JButtons ( 2 x 2 grid), and I need the background colour of individual JButtons to change, and after one second, change back to the original colour (the game I'm trying to make is like Simon, where you have to follow a pattern of buttons that light up). I have a vector that contains randomly generated numbers in the range of 1 to 4, and I want to be able to get each element from the vector and get the corresponding button to change to a different colour for one second (for example, if the vector contains 2 4 1, I would want button 2 to change, then button 4 to change, then button 1 to change). Is this possible or is there a better way to go about doing this with something other than JButtons? How do I implement this? Also, I'm running Mac OS X, which apparently (based on some things I've read on forums) doesn't like JButtons background changing (I think it's because of system look and feel), how can I change this so it works on mac? Thank you in advance for any help :)

• iPhone UIView Animation Disables UIButton Subview

  - by bensnider

  So I've got a problem with buttons and animations. Basically, I'm animating a view using the UIView animations while also trying to listen for taps on the button inside the view. The view is just as large as the button, and the view is actually a subclass of UIImageView with an image below the button. The view is a subview of a container view placed in Interface Builder with user interaction enabled and clipping enabled. All the animation and button handling is done in this UIImageView subclass, while the startFloating message is sent from a separate class as needed. If I do no animation, the buttonTapped: message gets sent correctly, but during the animation it does not get sent. I've also tried implementing the touchesEnded method, and the same behavior occurs. UIImageView subclass init (I have the button filled with a color so I can see the frame gets set properly, which it does): - (id)initWithImage:(UIImage *)image { self = [super initWithImage:image]; if (self != nil) { // ...stuffs UIButton *tapBtn = [UIButton buttonWithType:UIButtonTypeCustom]; tapBtn.frame = CGRectMake(0, 0, self.frame.size.width, self.frame.size.height); [tapBtn addTarget:self action:@selector(buttonTapped:) forControlEvents:UIControlEventTouchUpInside]; tapBtn.backgroundColor = [UIColor cyanColor]; [self addSubview:tapBtn]; self.userInteractionEnabled = YES; } return self; } Animation method that starts the animation (if I don't call this the button works correctly): - (void)startFloating { [UIView beginAnimations:@"floating" context:nil]; [UIView setAnimationDelegate:self]; [UIView setAnimationCurve:UIViewAnimationCurveLinear]; [UIView setAnimationDuration:10.0f]; self.frame = CGRectMake(self.frame.origin.x, -self.frame.size.height, self.frame.size.width, self.frame.size.height); [UIView commitAnimations]; } So, to be clear: Using the UIView animation effectively disables the button. Disabling the animation causes the button to work. The button is correctly sized and positioned on screen, and moves along with the view correctly.

• Toolbar hiding on rotated UISplitView DetailView

  - by Gerry

  I've based my app on Apple's SplitView project type. I have a TableView as the Master, and am using different types of views as the Detail view. To select types of detail view, I'm using the fancy concept of buttons on my DetailView toolbar. When the DetailView is derived from UIViewController, everything is good. When the DetailView derives from UIViewController, but contains a UITableView then I have problems. In portrait view the toolbar is visible. In landscape mode the toolbar is hidden, even though the Tableview is moved down to allow space for it. The UIToolbar and UITableView are both defined in my NIB file which is loaded to create the detail view. Why is my toolbar invisible in landscape? BTW, is this the best way to choose Detail view types with UISplitView? Bonus question, what if selecting a row in my DetailView tableview should bring up another View, I can't push it like I would with a NaviagtionController, so how do I go back to the detail tableview? Thanks, Gerry

• dynamic link_to_remote in rails with jquery

  - by Claus Lensbøl

  Hi I'm trying to pass a string with a link_to_remote call as the :id, and the string should be collected from an input field with and id of "movie_title". <div id="search_list">Nothing here yet</div> <br /> <% semantic_form_for @movie do |f| %> <% f.inputs do -%> <%= f.input :title, :class => "movie_title" %> <%= link_to_remote( 'Search...', { :url => { :action => :imdb_search, :id => "'+$('\#movie_title').value+'" } }, { :title => "Search for this movie", :class => "imdb_search" } ) -%> [...removed text that does not matter...] <% end -%> <%= f.buttons %> <% end %> I keep getting an javascript error, and if I remove the # from the jquery in the link, it returns "Undefined". The link I get is: <a class="imdb_search" href="#" onclick="jQuery.ajax({data:'authenticity_token=' + encodeURIComponent('yHPHYTZsPTQLi9JYSauUYcoie/pqPPk2uHBTN0PzNsQ='), dataType:'script', type:'post', url:'/movies/imdb_search/'+$('%23movie_title').value+''}); return false;" title="Search for this movie">Search...</a> So I want the link updated with the contents of movie_title. How do I do that?

• Adding a UITapGestureRecognizer to a view then removing seems to short circuit button events

  - by heymon

  In the code below I am popping up a ImageView as the result of a users touchUpInside on a simple info button. There are other buttons on the view. To dismiss the info I added a UITapGestureRecognizer to my controllers view, and hide the view when the tap is detected. If I don't remove the tapGestureRecognizer, the action is called every time some. Even when I do remove the gesture action, no bottons receive touchUpInside events once this gesture recognizer is added. Why? Code from my MainViewController (void) dismissInfo: (UITapGestureRecognizer *)gesture { [kInfoView setHidden: YES]; [gesture removeTarget: self action: NULL]; } (IBAction) displayInfo { CGRect startFrame = CGRectMake(725, 25, 0, 0), origFrame; CGFloat yCenter = [kInfoView frame].size.height/2 + 200; CGPoint startCenter = CGPointMake(724, 25), displayCenter = CGPointMake(384, yCenter); UITapGestureRecognizer *g = [[UITapGestureRecognizer alloc] initWithTarget: self action: @selector(dismissInfo:)]; [self.view addGestureRecognizer: g]; origFrame = [kInfoView frame]; [kInfoView setCenter: startCenter]; [kInfoView setHidden: NO]; [kInfoView setFrame: startFrame]; [UIView beginAnimations: @"info" context: nil]; [UIView setAnimationDuration: .5]; [UIView setAnimationDelegate: self]; [kInfoView setFrame: origFrame]; [kInfoView setCenter: displayCenter]; [UIView commitAnimations]; }

• Help with iphone button pressed

  - by StealthRT

  I am trying to see which button was clicked on so I can preform the correct logic. This is the code for the buttons: UIButton *button = [[UIButton alloc] initWithFrame:CGRectMake(270, 423, 60, 60)]; [button addTarget:self action:@selector(buttonPressedAction:) forControlEvents:UIControlEventTouchUpInside]; [button setBackgroundImage:[[UIImage imageNamed:@"refreshicon.png"] stretchableImageWithLeftCapWidth:10.0 topCapHeight:0.0] forState:UIControlStateNormal]; UIButton *button2 = [[UIButton alloc] initWithFrame:CGRectMake(0, 423, 60, 60)]; [button2 addTarget:self action:@selector(buttonPressedAction:) forControlEvents:UIControlEventTouchUpInside]; [button2 setBackgroundImage:[[UIImage imageNamed:@"login.png"] stretchableImageWithLeftCapWidth:10.0 topCapHeight:0.0] forState:UIControlStateNormal]; [self.navigationController.view addSubview:button]; [self.navigationController.view addSubview:button2]; And this is how I call the buttonPressedAction: - (void)buttonPressedAction:(id)sender { NSLog(@"%@", [sender value]); isRefreshing = TRUE; [self loadTheXML]; [self.tableView reloadData]; } But when I use NSLog to see what the sender value is, it crashes. Any advice for what's happening and how to correct it?
