  • How can I get a nstableview to send an action when the user double-clicks an editable cell

    - by overcyn
    I am trying to emulate the behavior found in finder and itunes. Single click on a selected object edits it. Double click opens the object. I have set the doubleAction of the tableView but like it says in the documentation. "If the double-clicked cell is editable, this message isn’t sent and the cell is edited instead." I dont want this. Is there a way i can get that message sent even if the cell is editable? I really have no idea how to begin implementing this. Any general pointers would be appreciated.

  • Why aren't Admob click callback delegate methods not getting called?

    - by executor21
    I'm integrating the latest version of the admob sdk (version 20100412) into my app. The ads get displayed, but I need the app to make some changes when an ad is clicked and admob displays a full-screen browser. However, none of the callback methods (willPresentFullScreenModal, didPresentFullScreenModal, willDismissFullScreenModal, and didDismissFullScreenModal) are called, even though other delegate methods are. Why aren't these callbacks being made? They were in the previous versions of the SDK, and the sample app doesn't use them, so it's no help.

  • Core Data: Mass updates possible?

    - by wgpubs
    Is it possible to do mass updates on a given entity in Core Data? Given an Person entity for example, can I do something like this: Person.update(@"set displayOrder = displayOrder + 1 where displayOrder > 5") Or is my only option to fetch all the entities needed and then loop through and update them individually??? Thanks

  • Forcing Reload of View when returning from FlipSideView of Utility Application

    - by Chris McCall
    I've got a Utility Application for iPhone 3.1.3. I have my main view loading fine. I flip over to the flipside view of the utility app and change some settings. How can I call the code I've currently got in viewDidLoad in the main view to refresh it, as settings have changed? Do I create a public method and call it from the viewDidUnload method of the flipside view? Do I call viewDidLoad directly? What's the best way to do this?

  • If a NSView uses autolayout, do all of its subviews also need to use autolayout for positioning?

    - by boyfarrell
    I have a view in a window, the position and size of the view are calculated with autolayout. The view has a subview, a draggable NSView subclass. It is really easy to make a NSView "draggable" by overriding -mouseDown: and -mouseDragged: and changing the frame of the view directly. The view hierarchy is as follows, What is the best way of making the subview draggable in this case? For example, Is it possible for the subview to not use autolayout, so that it can be positioned by changing the frame directly? i.e. the window positions the main view, but then autolayout does not layout the subview inside the main view. Or to all views in the hierarchy need to use autolayout. When I have used autolayout before, I have used it to make "fixed" layout that respond to resizing. But dragging a view with a mouse does't seems like a natural use case for autolayout.

  • Can't access UI from a delegate?

    - by Nick Brooks
    I got this code: GrooveOnDownload *dlg = [[GrooveOnDownload alloc] init]; NSURLDownload *dw = [[NSURLDownload alloc] initWithRequest:request delegate:dlg]; It starts the download in a delegate class with outlets for UI controls. But for some reason controls don't respond to direct messages from the delegate. //Header of the delegate @interface GrooveOnDownload : NSObject { IBOutlet id downloadButton; //... //Implementation //... [downloadButton setEnabled:FALSE]; // Doesn't work //... Any ideas?

  • Best way to create Default.png image for iPhone app

    - by Alex
    Originally I though I'll just take a screenshot of my app on the iPhone then tweak it in Photoshop. The images should be 480 x 320 according to Apple doc, and the dimensions of my screenshot are 480 x 320. But, the screenshot contains notification area (where reception bars, battery life, etc. are displayed) So, if I chop that part off my image will be a bit shorter and not 480px high. What do I do? Submit a shorter image? Stretch it up so it's 480px but without the notification bar? Submit it with the notification bar in the image? How did you create your Default.png?

  • Webview blank but content is there

    - by Scott Dugas
    I am having trouble displaying a webview. I have a webview inside a custom view. I load this custom view as a subview of the window, and then have an object controller linking a text field to the content of the web view. Once a page is loaded, it loads all the content, but it is visually white. You can click on links. If you go to a Youtube video you can listen to it, but it still displays nothing.

  • CADisplayLink stops updating when UIScrollView scrolled

    - by Tricky
    Title is quite self explanatory, but I have some animation being done in a loop triggered by CADisplayLink. However, as soon as I scroll a UIScrollView I have added to my view hierarchy, the animation stops immediately, only to return again when scrolling has completely stopped and come to a standstill.... Anyway to cancel this behaviour?

  • Optional Navigation Controller

    - by Kevin Sylvestre
    I have an application containing a variety of view controllers linked together in different ways (Welcome Browse Preview OR Browse Preview OR Settings Splash). The first view controller is presented modally using a navigation controller from a main controller, then the next set of view controllers are added using pop and push. This works correctly, but I need to be able to define my 'UINavigationBar' and 'UIToolbar' within interface builder, so they still work as expected if they are presented without using a navigation controller. Is this possible? Currently I get this if I try:

  • iPhone: Going from transformed layers to jpeg

    - by Devin Ross
    I have a bunch of images that are transformed (using touch gestures). I want to take the transformations the user does to the images and create a jpeg from it. (ie. if a user rotates a photo to the right, I want to get a jpeg of the photo rotate to the right just as the looks on screen). This takes into account that the photo could be bigger than whats displayed on screen too (no screenshots). I'm trying to use CGContext (CGContextRotateCTM specifically) but its not been too successful. Thanks for the help.

  • Make an NSString accessible in the whole class

    - by OhhMee
    Hello, I want to know how can I make an NSString accessible in the whole class. Say I have these codes: - (void) init { NSArray *elements = [xpathParser search:@"//foo"]; TFHppleElement *element = [elements objectAtIndex:0]; NSString *data = [element content]; NSArray *elements1 = [xpathParser search:@"//foo2"]; TFHppleElement *element2 = [elements1 objectAtIndex:0]; NSString *data2 = [element2 content]; } And I want to use data & data2 in the whole class, how can I do that? I want to show results here: - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"Cell"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease]; } // Configure the cell. switch (indexPath.row) { case 0 : cell.textLabel.text = (@"%@", data); break; case 1: cell.textLabel.text = (@"%@", data2); break; } // Email & Password Section return cell; }

  • NSView only redraws on breakpoint

    - by Jacopo
    I have a custom view inside a NSPopover. It should change according to user input and it does the first time the user interact with it but it fails to redraw the following times. I have tried to put an NSLog inside the -drawRect: method and it doesn't get called during normal execution. When I try to debug and put a breakpoint inside the method it gets called normally and the app works as it should. I explicitly call the view -setNeedsDisplay: method every time I need it to redraw. I don't understand why it should make a difference. Here is the code that update the status of the view. These methods are part of the NSTextField delegate method -textDidChange: and I checked that these get called every time the user type something in the textfield associated with popover. [tokenCloud tokensToHighlight:[NSArray arrayWithObject:completeSuggestionString]]; tokenCloud.tokens = filteredTokens; [tokenCloud setNeedsDisplay:YES]; The views is a series of recessed button. The first line update the status of all the buttons in the popover and the second add or delete buttons. They both work properly because the first time they are called the view is update properly. I have also checked that both the status of the buttons in tokenCloud and its property tokens are updated correctly. The problem is that the NSView subclass, tokenCloud, doesn't redraw so the changes are not reflected in the UI the second time. Here is the draw method of the view: - (void)drawRect:(NSRect)rect { [self recalculateButtonLocations]; NSLog(@"Redrawn"); } Again this method gets called normally every time I update the view if I place a breakpoint in [self recalculateButtonLocations];. If instead I let the app run normally nothing gets logged in the console the second time I update the view. Same thing if I include the NSLog in the recalculateButtonLocations method, nothing gets logged the second time meaning that the method is not called.

  • Retrieving Data in A NSTableView

    - by Heisennberg
    I have a three column Table View populated by two NSMutableDictionaries which share the same keys (ie key | value1 | value2 ) with dict1(key,value1) and dict2(key,value2). I want to manually enter data in the third column and create the key/value objects in dict2. But when I do that, my code picks the wrong key :S Here's the code for the delegate : - (void)tableView:(NSTableView *)aTableView setObjectValue:(id)anObject forTableColumn:(NSTableColumn *)aTableColumn row:(NSInteger)rowIndex { if ([[aTableColumn identifier] isEqualToString:@"value2"]) { [dict2 setValue:anObject forKey:[[[aTableView tableColumnWithIdentifier:@"key"] dataCellForRow:rowIndex] stringValue ]]; } } Any idea ?

  • Upload Image to Facebook Objective-C

    - by boopyman
    I'm currently trying to upload an image from my Mac application to Facebook. To do this, I'd like for the user to simply input his username and password, and to click a button. The only issue is, Facebook doesn't actually have an API for the Mac, it only has one for iOS. This shouldn't be a problem, except for the fact that to login, you must use a web view, something I'm not to keen on doing, since I'd like the interface to be two simple text fields. I've also looked into PHFacebook, a class I found online, but it also seems to utilize an NSWebView. I'm wondering if there's a security issue when you use text fields; indeed, it's slightly strange no available API offers this function ! So, to conclude, is it possible, or is there an API, that lets you upload an image and lets you provide the user's credentials through simple NSStrings?

  • Template apps for iPhone

    - by rob
    Is there a good place to get starter apps for iPhone, where you choose from any of a large set of permutations?...for instance with a nav bar and a flip screen and a 3 deep table view, with Core Data support etc. I guess what I was hoping for is some kind of wizard where you can check a few boxes and have a working app as a starting point....but more than just the 3 or 4 choices that come with xCode. If not a wizard, just a nice set of a couple dozen permutations. Also....is there any good sample apps out there that show the difference between identical apps, one which uses Interface Builder and one not? Aside from being handy for myself, I'd think these would be great as a teaching tool. I've googled a bit and come up with nothing.
