I have an app that is built on the TabBar-based app in which I need to have one tab that is basically an email composer. So I'm trying to use a MFMailComposeViewController as one of the tabs. This seems to work fine until I actually go to send an email with the controller. If I do this the MFMailComposeViewController's view disappears...
I have a UIButton that's 90x90 in size and I would like it to glow when tapped. Using showsTouchWhenHighlighted will make it glow but it's glowing out of the center of the button and for a small radius only. This might work well for a small button like the info button, but for my button size, it's not. Is there anything I can do to ma...
OK, I'm having some problem with the UITextView. Here's the issue: I add some text to a UITextView. The user then double clicks to select something.

Problem: I need to fire values to an object 10 times per second. I must be able to start firing and stop firing. I've discovered that the delegate of an UIScrollView gets notified in about the same time intervals, no matter how fast the scrolling is.

For some reason, every time I run my Iphone App, the App works fine as long as it is upright. The second the simulator turns to the left or right (like if I manually turn it, or if it's trying to play a video), the code crashes, with either a "Bad Access" or an exception. The crazy thing is that this stuff was JUST working, and I didn't...
