I'm making an iPhone-app with particles moving on a custom UIView, drawn with Core Graphics. I want my particles to leave a trace, so when the view is repainted I want it to fill the background with 0.8 alpha. Anyone knows how to do this? I've tried setting the background color of the view to something transparent in IB, but that doesn...

I have a subclass of UIView in which I've added some subviews to in my initWithFrame method. I've added a background, amongst other things. I want to draw some shapes on top of these views (which happen to cover the entire screen). But, when I implement drawRect: to draw these shapes, they didn't show up.

I'm probably not doing this correctly. Having not done an iPad app before I'm doing what seems natural to me. I have a UIView that is going to be made of up other UIViews. Specifically, I want to dynamically create and add subviews to each of these subviews. In other words: UIView | | --> UIView | | --> Dyna...
I receive a crash on the call to the function set in setAnimationDidStopSelector when my view is animating as I remove the view and release the object. I'm not 100% certain that this is simply a case of a UIView animating while being released and the callback issued by the animation being called into a released object, but I suspect it ...

Hello, I created a UIView which has two controls on it, a label and an activity indicator (spinning wheel) to display when the device is synchronizing.

Hi. I have a table with several text fields in it. Tapping on any of the text fields brings up the keyboard and the view scrolls automatically to bring the cursor above the keyboard if required.

When the button is pressed I can retrieve which button it is in string format, for example "settings" and I would like to then run the object -(void)settings{}....

How can I solve this ...

UIView *stateView = [getSomeUIView thisOne]; CGRect currentFrame = stateView.frame; if(currentFrame.size.height == 0.0) { currentFrame.size = CGSizeMake(260, 60); } else { currentFrame.size = CGSizeMake(260, 0); } stateView.frame = currentFrame; I would expect all the subviews would be hidden when the height of the frame is set...
