Question

I am facing some strange issue in my app.

in my ViewDidLoad() method I set title of my button as follows.

[btnA setTitle:@"A" forState:UIControlStateNormal];

On another click event I want to set the value of this title as nil as follows.

[btnA setTitle:nil forState:UIControlStateNormal];

but when I print the log immediately after above statement as follows

NSLog(@"btnA:%@",btnA.titleLabel.text);

It prints the log as follows

btnA:A

and strangely when I run app in simulator the text of button shows me nothing so it becomes nil on click event.

What is the problem any guess?

Try Following code

button.titleLabel.text   = @"";

or in your own code try with delay

- (IBAction)produceImage:(id)sender
{

     // Call another function which setthe title after delay

    [self performSelector:@selector(title:) withObject:sender afterDelay:2];

}

- (IBAction)title:(id)sender
{
   [sender setTitle:@"" forState:UIControlStateNormal];

      NSLog(@"sender:%@",sender.titleLabel.text);


}
