Thanks.

Answer 1

Programatically, you can do something like this... http://www.iphonedevsdk.com/forum/iphone-sdk-development/1891-changing-button-image-code.html

Answer 2

So the suggestion from http://www.iphonedevsdk.com/forum/iphone-sdk-development/1891-changing-button-image-code.html is:

UIButton *btn = [[UIButton alloc] init];
UIImage *img = [UIImage imageNamed:@"image.png"];
[btn setImage:img forState:UIControlStateNormal]
[img release];

Answer 3

you dont need to release img. So the correct code could be -

UIButton *btn = [[UIButton alloc] init]; UIImage *img = [UIImage imageNamed:@"image.png"]; [btn setImage:img forState:UIControlStateNormal];
