Delay between animation cycle on a UIImageView

Question

I have an UIImageView called imgView, where i have an array of images, like,

  imageArray objects: [UIImage imageNamed:@"test4.png"],
                    [UIImage imageNamed:@"test5.png"],
                    [UIImage imageNamed:@"test6.png"],
                    [UIImage imageNamed:@"test7.png"],
                    nil];

then i have added the array images in imgView animation, like

imgView.animationImages = imageArray;
imgView.animationRepeatCount = 0;
imgView.animationDuration = 2.0f;

[imgView startAnimating];

Here every thing works fine. I have to delay 5sec after one cycle of animation finishes. How can i do this, i have used

 [self performSelector:@select...

but not working, please give me any idea.

try this:

-(void) viewWillAppear:(BOOL)animated {
    [super viewWillAppear:YES];

    [self animationMethod];  //where you start the animation
}

-(void) animationMethod {
    NSMutableArray *imageArray  = [[NSMutableArray alloc] initWithObjects:[UIImage imageNamed:@"btnVideoEffectSample1.png"], [UIImage imageNamed:@"btnVideoEffectSample2.png"], [UIImage imageNamed:@"btnVideoEffectSample3.png"], [UIImage imageNamed:@"btnVideoEffectSample4.png"], nil];
    imgProfilePicture.animationImages = imageArray;
    imgProfilePicture.animationRepeatCount = 0;
    imgProfilePicture.animationDuration = 2.0f;
    [imgProfilePicture startAnimating];
    [imageArray release];

    double delayToStopAnimation = 2.0;
    dispatch_time_t startTime = dispatch_time(DISPATCH_TIME_NOW, delayToStopAnimation * NSEC_PER_SEC);
    dispatch_after(startTime, dispatch_get_main_queue(), ^(void){
        [imgProfilePicture stopAnimating];

        double delayToRestartAnimation = 5.0;
        dispatch_time_t startTime = dispatch_time(DISPATCH_TIME_NOW, delayToRestartAnimation * NSEC_PER_SEC);
        dispatch_after(startTime, dispatch_get_main_queue(), ^(void){
        [self animationMethod];
        });
    });
}

i need to put all these lines? imgView.animationImages = imageArray; imgView.animationRepeatCount = 0; imgView.animationDuration = 2.0f; [imgView startAnimating]; — Harish, May 15 '13 at 06:55

After 1 cycle complete use [imgView stopAnimating];and remove from super view if want.After this put an NSTimer which will be called after 7 sec and again restart your animation because whole image cycle takes 2 sec and total time will be taken 2 sec to complete animation. After this you want 5 sec break then total time will be 7 sec.Again your method will start animation from NStimer method calling like-

[NSTimer timerWithTimeInterval:7.0 target:self selector:@selector(startAnimation) userInfo:nil repeats:YES];

Hope this helps.

how can i detect that one cycle has been completed? – Harish May 15 '13 at 06:39
when you start animating after 8 sec your cycle will be ended because each image has to take 2 sec and you have 4 images – iEinstein May 15 '13 at 06:44
after [imgView startAnimating]; given how can i detect 8 sec has been finished..? – Harish May 15 '13 at 06:52
Just stop animation after repeat count you can see it will take 8 sec – iEinstein May 15 '13 at 07:02
