Objective-C toggle on/off images

December 15, 2009 § Leave a comment

It’s simple way to use a custom image for UIButton and set the UIButton to switch in between the UIControlStateNormal & UIControlStateSelected.

This is a common use case to show a play or pause button depending on he UIButton state status.

UIButton * customButton=[UIButton buttonWithType:UIButtonTypeCustom];

[customButton setBackgroundImage:[UIImage imageNamed:@”Play.png”] forState:
UIControlStateNormal];

[customButton setBackgroundImage:[UIImage imageNamed:@”Pause.png”] forState:
UIControlStateSelected];
