UIButton 背景图像 以编程方式更改

Question

How can I change the background image of my UIButton in click event? And refresh it in a few second with the previous image? I mean change it's background image on click and reset it after the click.

Answer 1

[yourButton setImage:[UIImage imageNamed:@"yourNormalImage.png"] forState:UIControlStateNormal];
[yourButton setImage:[UIImage imageNamed:@"yourImageWhenClicking.png"] forState:UIControlStateHighlighted];

put your clickEvent image as highlighted image of your button..

Answer 2

The above answer is not working because it doesn't change the background but the side image of the UIButton , to change the background image use:

[yourButton setBackgroundImage:[UIImage imageNamed:@"yourimage"] forState:UIControlStateNormal];
