iPhone image button

Question

I want to use image buttons in my iPhone application. Could you please let me know if there is any article I can read on this.

Thanks.

Answer 1

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]
//No need to release img. It is autoreleased!!!

Answer 2

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];

Answer 3

In Interface Builder you can choose a Custom button and then set the Image property to your image. Don't use Rounded rect button, it will show behind the image.

Answer 4

以编程方式，你可以做这样的事情...... http://www.iphonedevsdk.com/forum/iphone-sdk-development/1891-changing-button-image-code.html

Answer 5

但你需要释放按钮;）[btn release];
