I have an app that has UITabBarController with two UIViewControllers as its tabs. In the first UIViewController.view I have a continuous animation with repeat count set to INT_MAX. It worked fine until 3.2 and 4.0. On 3.2 or newer, when I switch to a different tab, OS skips to the end of my animations and invokes -animationDidStop:fi...
Hello, I would like to intercept the touch on the camera button to control exactly when I take the picture by using takePicture.

Hi, I have a problem I don't understand regarding UIViews and Core Animation. Here's what I want to do: A small view is presented above a bigger view by putting it as one of its subviews.

In other words, after doing this: _myNavItem = [[UINavigationItem alloc]initWithTitle:@"Home"]; [self.navBar pushNavigationItem:_myNavItem animated:NO]; do I need to release _myNavItem with: [_myNavItem release]; in order to avoid a memory leak? Also, how do I find o...

I have a view controller managed in a UINavigationController. My view controller puts up a "loading" screen, and uses ASIHTTP to asynchronously load table data. Then it renders its table, and in each cell there's an image that it uses ASIHTTP to asynchronously load. When it lands each image, it uses [self.tableView reloadRowsAtIndexPaths...

I'm just learning the iPhone SDK and about drawing with CG and UIKit and whilst I can see the usefulness for building interfaces as a web developer I can't help but think it would be a hell of a lot easy if I could layout content (ie heading, paragraphs, lists, images) with html and css presumably this is possible using the web view and...
I'm writing an app that uses UITabBar for parts of the navigation. I'm also using UIScrollView for presenting more information than what the screen can typically handle. Because of this, I'm needing to set the scroll view to take into account the height of the UITabBar so that all of the information is displayed. Is there a way to calcu...
