I have a UIView with a bunch of buttons in it (something like 200 of them)... The view was set up in IB so I would have to manually wire every button with a single handler... I'm trying to traverse the subviews of the view, looking for buttons and then set the button's target programmatically... which results in a crash (I get the comp...

I am trying to implement a clickable image that is able to repeatedly cycle through three or more images. I don't need to interact with the images once the cycle is set up. The cycling is time based, rather than event based. The images should smoothly transition from one to another. What is the best way to approach this problem? My fir...
Hi, I'm writing an iPhone app which needs an extremely rapid response for a touch event. Is there any object that will provide a faster response than the UIControlEventTouchDown result of a UIButton loaded from a nib? I'm open to any resources that don't require extensive digging around or reverse engineering. Thanks in advance! Luke ...

Hello, As everyone knows, setTitle automatically retains the string passed as a parameter. When the button caption needs to be changed, I guess that it is necesary to release the current (old) string before setting the new one. I wonder what is the most elegant way to dot it. See my code sample (here, getPlayerHandFromGame method produ...
I'm trying to display a small refresh button using UIButton in a standard UIView using the refresh icon built into UIKit. If I use an UIBarButtonItem it can be created as a refresh button, but I've had no luck in using this icon in other places. So far I've tried to "steal" the refresh image of a UIBarButtonItem using the code below, bu...
I'm creating a menu and I want the buttons to "pop" I guess on the screen. Basically I want to start at 0px dimensions and then go up to the full size of the buttons. I can animate the alpha and the position if I want to but can't do the dimensions and I think its because its an image on the button. If I do a UIButtonTypeRoundRect you c...
We are trying to add a UIButton to out iPhone app that will direct users to the iStore to show a list of all our apps. We got the button to display an NSLog() so we are almost there.

I'm new to iPhone dev. My app is dynamically creating buttons, following from my data model. The model isn't just a simple list; it's a tree. I need some way to correlate a created button to that data model, so that when the button is clicked I know what part of the model it corresponds to. On Windows, most UI controls have a "tag" fiel...
