good day.. I have this code.. and this two is for actionAnimating Button and stopAnimating Button..I just want to know if how to make those two button integrate in ONE button.. for example.. I click the button then it animates.. when I click again that actionAnimating Button, i want to cancel/stop the animation at the same time i want to play/animate again.. in short i want to cancel the animation when i click again the actionAnimating button..
-(void)flowerAnimationSequence//START ANIMATION
{
MotherView.alpha = 0;
flower.alpha = 0;
[animationContainer1 removeFromSuperview];
actselected = YES;
NSLog(#"start");
if (((sequenceAnimateCounter == 0) || (sequenceAnimateCounter==1)) && (actselected = YES))
{
aImageViewSlideShow = [[UIImageView alloc]initWithFrame:CGRectMake(0, 0, 320, 480)];
aImageViewSlideShow.tag = 171;
[self.view addSubview:aImageViewSlideShow];
}
if (sequenceAnimateCounter < 183)
{
timer = [NSTimer scheduledTimerWithTimeInterval:0.035 target:self selector:#selector(flowerAnimationSequence) userInfo:nil repeats:NO];
}
else if (sequenceAnimateCounter ==183)
{
aImageView = (UIImageView *)[self.view viewWithTag:171];
NSLog(#"done");
actselected = NO;
sequenceAnimateCounter = 0;
[aImageView removeFromSuperview];
aImageView = nil;
[self DefaultPosition];
}
aImageView = (UIImageView *)[self.view viewWithTag:171];
NSString *aStrNumber = [NSString stringWithFormat:#"%i",sequenceAnimateCounter];
NSString *aBundlePath = [[NSBundle mainBundle]bundlePath];
NSString *aImagePath = [NSString stringWithFormat:#"%#/sapatos_%#.png",aBundlePath,aStrNumber];
[aImageView setImage:[UIImage imageWithContentsOfFile:aImagePath]];
[self.view bringSubviewToFront: aImageView];
sequenceAnimateCounter = sequenceAnimateCounter+1;
if (sequenceAnimateCounter == 1)
{
[aImageView removeFromSuperview];
}
}
-(void)stopanim//STOP BUTTON
{
[timer invalidate];
sequenceAnimateCounter =0;
NSLog(#"stop");
[aImageView removeFromSuperview];

Hm...
you want to start/stop in one button?
BOOL isAnimating = NO;
- (void)startStopAnimating
{
if (!isAnimating) {
isAnimating = YES
// start animation
} else {
isAnimating = NO;
// stop animation
}
}
