Why will this if statement not work? Xcode

Question

@implementation ViewController
-(IBAction)changelabel {
NSString *string1 =entername.text;
NSString *string2 =@"Alan Shearer";
NSString *string3 =@"Alan Shearer 260 Goals";

if([string1 isEqualToString:string2])

{label.text=string3;}
}

I want it so, when the user enters "Alan Shearer" into a text field it changes the label to Alan Shearer

Add a sender to your method

-(IBAction)changeLabel:(id)sender

I have done so, it still does not work and it shows no errors. When I run the app, and press check, it closes the app. – Jeevan Thandi Sep 23 '12 at 14:49

What does NSLog(@"%@", string1) write? Your NSString comparison method is right.

How do I view NSLog? There are no errors and it still does not work and it shows no errors. When I run the app, and press check, it closes the app. – Jeevan Thandi Sep 23 '12 at 14:50
Just add this piece of code before your `if` statement and look in console output. – dreamzor Sep 23 '12 at 14:51
that obviously means the method is not called, which indicates you didn't make up a connection with the `IBAction`. – dreamzor Sep 23 '12 at 21:16
