Problem in calling method using NSTimer?

Question

Hi, I want to call the method after particular time only one time therefore i was written an statement as following.

    imageAnimationTimer = [NSTimer scheduledTimerWithTimeInterval:1.0 target:self selector:@selector([self imageViewAnimation:imageViewObject]) userInfo:nil repeats:NO];

Above won't be worked. Why? It give me some strange problem. How i calling and sending arguments along-with it using NSTimer:scheduledTimerWithTimeInterval:target:selector:userinfo:repeats:

Answer 1

Your selector is defined incorrectly.

imageAnimationTimer = [NSTimer scheduledTimerWithTimeInterval:1.0 target:self selector:@selector(imageViewAnimation:) userInfo:imageViewObject repeats:NO];

I would suggest simply using performSelector:withObject:afterDelay:

[self performSelector:@selector(imageViewAnimation:) withObject:imageViewObject afterDelay:1.0];

Check out the NSTimer and NSObject references for more details.

Answer 2

in addition to Jacobs comment (and you want to still use NSTimer - one reason you might want to use NSTimer is you can cancel it):

imageAnimationTimer = [NSTimer scheduledTimerWithTimeInterval:1.0 target:self selector:@selector(imageViewAnimation:) userInfo:imageViewObject repeats:NO];

your method prototype also needs to be:

- (void) imageViewAnimation:(NSTimer*) timer

my guess is you have this wrong also...though without a stack trace & console output, just guessing.
