How to unhide view with animations

Question

Say I have a hidden view in Xcode for iOS. Now, when I set the view to not hidden (view.hidden=NO), how can I make it so that it now appears, but with animations?

Answer 1

For a fade, you can adjust the alpha property of the view.

myView.alpha = 0;
[UIView animateWithDuration:0.5 animations:^{
    myView.alpha = 1;
}];

That will apply a fade in over 0.5 seconds to the view myView. Many UIView properties are animatable; you aren't just limited to alpha fades. You can change background colours, or even rotate and scale a view, with animation. If you need further control and advanced animation, you can then move into Core Animation - a much more complex animation framework.
