iOS - animate movement of a label or image - animation

Question

How can I animate the movement of a label or image? I would just like to make a slow transition from one location on the screen to another (nothing fancy).

Answer 1

For ios4 and later you should not use beginAnimations:context and commitAnimations, as these are discouraged in the documentation.
Instead you should use one of the block-based methods.
The above example would then look like this:
[UIView animateWithDuration:0.3 animations:^{ // animate the following:
myLabel.frame = newRect; // move to new location
}];

Answer 2

You're looking for the -beginAnimations:context: and -commitAnimations methods on UIView.
In a nutshell, you do something like:
[UIView beginAnimations:nil context:NULL]; // animate the following:
myLabel.frame = newRect; // move to new location
[UIView setAnimationDuration:0.3];
[UIView commitAnimations];

Answer 3

Here is an example with a UILabel - the animation slides the label from the left in 0.3 seconds.
// Save the original configuration.
CGRect initialFrame = label.frame;
// Displace the label so it's hidden outside of the screen before animation starts.
CGRect displacedFrame = initialFrame;
displacedFrame.origin.x = -100;
label.frame = displacedFrame;
// Restore label's initial position during animation.
[UIView animateWithDuration:0.3 animations:^{
label.frame = initialFrame;
}];
