Fire IBAction automatically

Question

I have a button and want to fire it automatically by itself without touch. Is it possible?

-(IBAction)xxx:(id)sender 

Answer 1

My answer assumes you have the method:

- (IBAction)someAction:(UIButton *)sender {
}

and that you have a reference to the button in an instance variable named someButton.

If you just need to "fire it" now, simply call it:

[self someAction:someButton];

If you need to "fire it" once, but later, you can do:

// call it 5 seconds from now
[self performSelector:@selector(someAction:) withObject:someButton afterDelay:5.0];

If you want to fire it repeatedly, use a timer:

myTimer = [NSTimer scheduledTimerWithTimeInterval:5.0 target:self selector:@selector(buttonTimerFired) userInfo:nil repeats:YES];

- (void)buttonTimerFired {
    [self someAction:someButton];
}
