Hey, I've been using CALayer to do all the custom drawing and animations and found it really nice to work with. But when I tried adding a navigation bar to the superview, it comes out as white.

So I am creating an class that does an animation. There is a timer delay. So I will instantiate this class. Have it do its thing then have a timerFinished type of delegate to continue on.

I have a problem that I solved using delegates, but now I am thinking I may have made a mistake. This is what I want to do. I have a class that runs on a delay. When it is done it has a finished delegate that it calls. Now I have the main class that creates two of these delay classes. I don't want them to both be handled by the sa...

I'm currently doing the following to clear out an NSMutableDictionary [myDictionary release]; myDictionary = [[NSMutableDictionary alloc] init]; The release line doesn't actually release any objects in the dictionary.

I have a UIProgressView that I'm using to visually represent a one-minute timer. Its width is 280 pixels. I'm using NSTimer to gradually decrease the value of 'progress', starting at progress=1.0.

The custom UIImageViews are simple and only introduce a few new properties that allow for tracking the imageviews within the scrollviews. Images load from disk very fast. The code below executes very fast but I have...

I assume I can build the form in Interface Builder, but I'm clueless as to where to go from there, even though I've read several resources on both (including the docs). Just not sure how to put two-and-two together. ...
I'm using a NSTimer to fire a drawRect within the app's main view. The drawRect draws a few images, and blends each using kCGBlendModeScreen (which is an absolute must). However, the drawRect takes just a tad longer than desired, so the timer doesn't always get fired at the desired rate (more like half as often). I've optimized the grap...
I load a UIImageView with an image depending on user interaction. When the parent view is initially displayed, no image has been selected and the imageview is black. If the user leaves that view and comes back, the image is still there. I've tried myImageView.image = nil; upon leaving the view but the image remains. How can I remo...
