How to use a UIButton as a toggle switch

Question

I am using a UIButton of custom type and what I want is use it like a toggle switch with the change of image. Like when it is clicked if previously it was not in selected mode it should go in selected mode or otherwise vice-a-versa. Also it will have a different image and when it is selected it will have a different image when it is not.

I am not able to do it programatically, is there any good easy way to do this.

Answer 1

I believe this post has a better solution : iPhone UIButton with UISwitch functionality

UIButton has toggling built in. There is a selected property that you can set and change the skins based on the state.

Answer 2

In your header file add:

IBOutlet UIButton *toggleButton; BOOL toggleIsOn;  @property (nonatomic, retain) IBOutlet UIButton *toggleButton; 

In the implementation:

- (IBACtion)toggle:(id)sender {   if(toggleIsOn){     //do anything else you want to do.   }   else {     //do anything you want to do.   }   toggleIsOn = !toggleIsOn;   [self.toggleButton setImage:[UIImage imageNamed:toggleIsOn ? @"on.png" :@"off.png"] forState:UIControlStateNormal]; } 

then link your button with the IBActions and the IBOutlet and initialize toggleIsOn to NO.
