UIButton does supports a "toggle" functionality by default. To use this you need to set a different image or even text color in Interface Builder for the State Configuration = Selected, and use the selected property of UIButton to toggle its state.

Code:

- (IBAction)yourButtonTouch:(UIButton *)sender {

    sender.selected = !sender.selected;
    if (sender.selected) {
        //...
        // Action to be performed when button is selected or 
        // the first touch
        // ... 

    }
}
