How to hide image view in ios?

Question

I have image view, if click button talking tom cat will play with animationRepeatCount:2, after this, I want to hide image view. How to hide that image view?

    - (IBAction)catBlinkButton:(UIButton *)sender {
    self.imageView.hidden = NO;
    self.imageView.animationDuration = 2;
    self.imageView.animationRepeatCount = 2;
    self.imageView.animationImages = [[NSArray alloc]initWithObjects:
                                      [UIImage imageNamed:@"cat_blink0000.png"],
                                      [UIImage imageNamed:@"cat_blink0001.png"],
                                      [UIImage imageNamed:@"cat_blink0002.png"],
                                      nil];

    [self.imageView startAnimating];

}

This is my code...

- (IBAction)catBlinkButton:(UIButton *)sender { self.imageView.hidden = NO; self.imageView.animationDuration = 2; self.imageView.animationRepeatCount = 2; self.imageView.animationImages = [[NSArray alloc]initWithObjects: [UIImage imageNamed:@"cat_blink0000.png"], [UIImage imageNamed:@"cat_blink0001.png"], [UIImage imageNamed:@"cat_blink0002.png"], nil]; [self.imageView startAnimating]; self.imageView.hidden = YES; } — , Jan 30 '17 at 05:46

You can simply use CATransaction like:

self.imageView.hidden = NO;

[CATransaction begin];

[CATransaction setCompletionBlock:^{

    self.imageView.hidden = YES;

}];

self.imageView.animationDuration = 2;
self.imageView.animationRepeatCount = 2;
self.imageView.animationImages = [[NSArray alloc]initWithObjects:
                                  [UIImage imageNamed:@"cat_blink0000.png"],
                                  [UIImage imageNamed:@"cat_blink0001.png"],
                                  [UIImage imageNamed:@"cat_blink0002.png"],
                                  nil];

[self.imageView startAnimating];

[CATransaction commit];

CATransaction will dynamically wait for the animation to finish...

You can execute the code after slate on main thread.

- (IBAction)catBlinkButton:(UIButton *)sender {

    self.imageView.hidden = NO;
    self.imageView.animationDuration = 2;
    self.imageView.animationRepeatCount = 2;
    self.imageView.animationImages = [[NSArray alloc]initWithObjects:
                                      [UIImage imageNamed:@"cat_blink0000.png"],
                                      [UIImage imageNamed:@"cat_blink0001.png"],
                                      [UIImage imageNamed:@"cat_blink0002.png"],
                                      nil];

    [self.imageView startAnimating];

    // after 2 seconds.
    dispatch_after(dispatch_time(DISPATCH_TIME_NOW, 2 * NSEC_PER_SEC), dispatch_get_main_queue(), ^{

        // hide imageview
        self.imageView.hidden = YES;
    });
}

You can do it with UIView's hidden property. imageView.hidden = true;
