Let Label blink

S1m0n18 · 08-15-2009, 05:04 AM

How can I make, that when I click my button, the Label starts to blink? E.g. to make an "S.O.S-Label" that blinks in the S.O.S-Rhythm..

Thx in advance

Create 2 timers, and set one to say interval 1.0. Set the other one to interval 2.0.

Make the function that the first timer calls hide the label. You can do this by:

Code:

myLabel.hidden = YES;

Make the second timer call a function then stops hiding the label.

Code:

myLabel.hidden = NO;

Hope that helps.

Stupid question, but how can I make a timer?

Code:

NSTimer *timer = [NSTimer scheduledTimerWithTimeInterval:1.0 target:self selector:@selector(hideLabel) userInfo:nil repeats:YES];

Then declare your function in the .h file:

Code:

- (void)hideLabel;

and in the .m file, do this:

Code:

- (void)hideLabel
{
      myLabel.hidden = YES;
}

and repeat for the showTimer function.

Hope that helps.
