如何在調用第二個動畫之後讓一個動畫永遠持續下去?例如:UIView兩個動畫並存
1)啓動的對象脈動 2)移動它,而它的脈動 3)它繼續脈動
一切正常,除了第二動畫無限期停止第一之一。 下面是一些示例代碼:
//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){
}];
