Objective C: Programmatically create a UIImageView

Question

I'm trying to make a UIImageView with a .png load up in the location of a button when it is clicked.

brickAnim = UIImageView.alloc;           ///////freezes during runtime
[brickAnim initWithFrame:currentBrick.frame];
[brickAnim setImage:[NSString stringWithFormat:@"brick-1.png"]];
[self.view addSubview:brickAnim];

current brick is the name of the button that's being clicked. I've narrowed it down and figured out that the first line causes the app to freeze and exit. I can't figure out what I'm doing wrong.

try

brickAnim = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"brick-1.png"]];
brickAnim.frame = currentBrick.frame;
[self.view addSubview:brickAnim];

edit after seeing response to other answer:

are you declaring and initializing brickAnim elsewhere? if not, you need to add at the beginning:

UIImageView *brickAnim = [[UIImageView alloc] ....;

and at the end:

[brickAnim release];

You need to create a UIImage first, since setImage wants an UIImage object. Something like this may work (note that this is a class method):

[brickAnim setImage:[UIImage imageNamed:@"brick-1.png"]];

Look at the UIImage reference, i'm not sure this will work (since imageNamed may want a different path-format).
