objective c - iOS compare button title to string

Question

I'm just learning how to code so thanks for your patience on this simple question.

Here's my code:

- (IBAction)buttonWasPressed:(id)sender {  
    NSString *buttonName = [sender titleForState:UIControlStateNormal];  
    if (buttonName == @"Button 1") {  
        do something 
    }

How do I compare the title of the button passed as sender to a string?

Much thanks for the help.

in objective-c you can't compare strings using "==", instead you should use the method isEqualToString from the NSString class to compare a string with another.

if ([buttonName isEqualToString: @"Button 1"]) {
  // do something
}
