在iOS中摇摆动画
|
我想知道是否可以在iOS中做某种摇摆动画。例如，摇摆动画就像商店的招牌在风中飘扬。想西方人。我想在按下按钮时做这种动画。我想要一种西方的感觉，那真的会让它脱颖而出。在此先感谢您是否知道如何做这样的事情。

然后创建一个函数，该函数在点击按钮时被调用，该函数开始向后摇摆动画，向后摇摆动画，最后一个向后移动到原始位置。您指定的度数是摇摆的方向，而rotationAndPerspectiveTransform中的第二个数字是摇摆的方向。 功能如下：-(void)sway:(id)sender{ CGFloat degrees = 50.0; CALayer *layer; layer = swaybtn.layer; CATransform3D rotationAndPerspectiveTransform = CATransform3DIdentity; [UIView beginAnimations:nil context:NULL]; [UIView setAnimationDuration:0.25]; [UIView setAnimationCurve:UIViewAnimationCurveEaseOut]; [UIView setAnimationDelegate:self]; [UIView setAnimationDidStopSelector:@selector(moveForward)]; rotationAndPerspectiveTransform.m34 = 1.0 / -400; rotationAndPerspectiveTransform = CATransform3DRotate(rotationAndPerspectiveTransform, degrees * M_PI / 180.0f, -1.0f, 0.0f, 0.0f); layer.transform = rotationAndPerspectiveTransform; [UIView commitAnimations]; } -(void)moveForward{ CALayer *layer; layer = swaybtn.layer; CGFloat degrees = 50.0; CATransform3D rotationAndPerspectiveTransform = CATransform3DIdentity; [UIView beginAnimations:@\"swayforward\" context:NULL]; [UIView setAnimationDuration:0.5]; [UIView setAnimationCurve:UIViewAnimationCurveEaseOut]; [UIView setAnimationDelegate:self]; [UIView setAnimationDidStopSelector:@selector(moveBack)]; rotationAndPerspectiveTransform.m34 = 1.0 / -400; rotationAndPerspectiveTransform = CATransform3DRotate(rotationAndPerspectiveTransform, degrees * M_PI / 180.0f, 1.0f, 0.0f, 0.0f); layer.transform = rotationAndPerspectiveTransform; [UIView commitAnimations]; } -(void)moveBack{ CALayer *layer; layer = swaybtn.layer; CGFloat degrees = 50.0; CATransform3D rotationAndPerspectiveTransform = CATransform3DIdentity; [UIView beginAnimations:@\"moveback\" context:NULL]; [UIView setAnimationDuration:0.25]; [UIView setAnimationCurve:UIViewAnimationCurveEaseOut]; rotationAndPerspectiveTransform.m34 = 1.0 / -400; rotationAndPerspectiveTransform = CATransform3DRotate(rotationAndPerspectiveTransform, degrees * M_PI / 180.0f, 0.0f, 0.0f, 0.0f); layer.transform = rotationAndPerspectiveTransform; [UIView commitAnimations]; }
