if/else textView not running

I have a if/else statement in my objective-c code. The if/else statement runs like this:

-(void)textViewDidBeginEditing:(UITextView *)textView
{
    if(textView==self.heardTextView)
    {
        NSString *string = textView.text;
        if ([string rangeOfString:@"CLOSER"].location == NSNotFound) {
            NSLog(@"closest");
        }

the premist of the if/else statement is. if the textview equals a certain word some code will run. But this code isn't running. I have put a breakpoint on my code and a NSLOG and nothing.
