Does Xcode have a similar shortcut? For example: In my .h, I define a class to conform to the UIPickerViewDelegate and UIPickerViewDataSource protocols...

First off, I'm trying to figure out a way, given a starting image created via [UIImage imageNamed:] to add decorations based on processing over time. (Think of a heat map.) I...

In a tab bar application, I'm adding a view to my first tabbar view by doing: [self.view addSubview:anotherView.view]; Once anotherView is done, I do: [self.view removeFromSuperview]; Which goes back to the parent but doesn't fire viewDidAppear or viewWillAppear on the parent.

I'm creating a draggable UIImageView much like the iPhone/iPod Touch's "Slide to Unlock" slider when the device is locked. I can get the view to move smoothly along the x-axis by using: float newCenter = touchPoint.x; But this doesn't take into account the offset of the touch from the center. It's simply moving the center point of the...
