调用第二个动画后,如何让一个动画永远继续?例如:
1) 开始一个物体脉动 2) 在它脉动的同时移动它 3) 它继续脉动
一切正常,除了第二个动画无限期地停止第一个动画。下面是一些示例代码:
//Pulsate **
[UIView animateWithDuration:0.25
delay:0
options: (UIViewAnimationCurveEaseOut | UIViewAnimationOptionAllowUserInteraction | UIViewAnimationOptionRepeat)
animations:^{
CGAffineTransform currentTransform = self.transform;
CGAffineTransform newTransform1 = CGAffineTransformScale(currentTransform, .95, .95);
[self setTransform:newTransform1];
CGAffineTransform newTransform2 = CGAffineTransformScale(currentTransform, 1, 1);
[self setTransform:newTransform2];
}
completion:nil];
//Move **
[UIView animateWithDuration:0.30
delay:0
options: (UIViewAnimationCurveEaseOut | UIViewAnimationOptionAllowUserInteraction | UIViewAnimationOptionBeginFromCurrentState )
animations:^{
[[(UIPinchGestureRecognizer*)sender view] setCenter:CGPointMake(myAppDelegate.MCViewReference.center.x-300, myAppDelegate.MCViewReference.center.y)];
}
completion:^(BOOL finished){
}];
