Question

i want to count the characters in a textview which are typed in by the user. I gave it some thoughts and my ideas were that I have to create a NSTimer with a selector which checks the length.
So I’ve got:

-(void)viewDidLoad { [NSTimer scheduledTimerWithTimeInterval:0.1 target:self selector:@selector(checkText) userInfo:nil repeats:YES];  }

-(void)checkText {

int characters;

label.text.length = self.characters;

characterLabel.text = [NSString stringWithFormat:@"%i", characters]; }

This doesn’t work because “Request for member “characters” in something not a structure or union”

How can I solve this problem?

There is no need for NSTimer. Setup yourself as textview’s delegate and implement:

- (void)textViewDidChange:(UITextView *)textView
{
    NSUInteger length;
    length = [textView.text length];

    characterLabel.text = [NSString stringWithFormat:@"%u", length]
}
