Set Individual Title of UIButtons in IBOutletCollection

Does anybody know how to set the title of each individual button in an array of buttons using an IBOutletCollection? This is what I have tried, but the code sets the title of all the buttons. I have connected the outlet to the buttons and set their respective tags.

.h file
@property (nonatomic, retain) IBOutletCollection(UIButton) NSArray *buttonCollection;

.m file
- (IBAction)switchAction:(id)sender {

    for (UIButton *btn in buttonCollection) {
        if (btn.tag == 0) {
            [btn setTitle:@"1st Button" forState:UIControlStateNormal];
        } else if (btn.tag == 1) {
            [btn setTitle:@"2nd Button" forState:UIControlStateNormal];
       } else if (btn.tag == 2) {
           [btn setTitle:@"3rd Button" forState:UIControlStateNormal];
       }
}
Solution

  • If you only want to set the title of the button you've clicked on, get rid of the for loop,

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

     if (sender.tag == 0) {
          [sender setTitle:@"1st Button" forState:UIControlStateNormal];
     } else if (sender.tag == 1) {
          [sender setTitle:@"2nd Button" forState:UIControlStateNormal];
     } else if (sender.tag == 2) {
         [sender setTitle:@"3rd Button" forState:UIControlStateNormal];
}
