Blinking effect on UILabel

How to make a UILabel blink in iPhone. I have tried googling and in SO also. But those questions are animating the label to change the colour. But I dont need to change the colour. I jus need the UILabel to blink. Is it possible?

Answer 1

Here’s the code snippet :

In your controller create a NSTimer property :

@property (strong, nonatomic) NSTimer *timer;

In your viewDidLoad method, start the timer :

self.timer = [NSTimer scheduledTimerWithTimeInterval:0.2 target:self selector:@selector(toggleLabelAlpha) userInfo:nil repeats:YES];

Finally write the function to toggle the label

- (void)toggleLabelAlpha {

    [self.label setHidden:(!self.label.hidden)];
}

Have fun
