[sender setSelected:NO]; } else { //... [sender setSelected:YES]; } } </code></pre> <p><strong>edit</strong><br> Your <code>toggleFav</code> code doesn't make much sense.<br> <code>if (favButton == nil) {</code> checks, if <code>favButton</code> is present. But if you are wiring it up with IB, it should always been there at that point. And if it wasn't how could the button call this method? So do it like this:</p> <pre><code>-(void)viewDidLoad { //.... UIImage *unselectedImage = [UIImage imageNamed:@"favUntapped.png"]; UIImage *selectedImage = [UIImage imageNamed:@"favTapped.png"]; [favButton setImage:unselectedImage forState:UIControlStateNormal]; [favButton setImage:selectedImage forState:UIControlStateSelected]; [favButton setFrame:CGRectMake(0, 0, 40, 40)]; //.... } -(IBAction)toggleFav:(UIButton *)sender { if([sender isSelected]){ //... [sender setSelected:NO]; } else { //... [sender setSelected:YES]; } } </code></pre> <p><strong>edit</strong><br> <a href="https://github.com/vikingosegundo/my-programming-examples/tree/master/Favorite">Here</a> you'll find an example project, with a DetaiView, that holds a Button with the 2 states.<br> <strong>Note:</strong> I am saving the information of what button was selected in the NSUserDefaults. You should not do that. Instead you'll want to save it in the model. But as I dont have informations on your model, I am just using NSUserDefaults.</p>
