在我的应用程序中,我使用了移动 subview 。如果它达到 y=150,我想制作一个跳跃效果的按钮,我试过这个链接 adding bounce effect to appearance of UIImageView 它在水平方向工作,我想要一个垂直方向,这是我的代码,
-(void)godown
{
if (movingview.center.y < 150) movingview.center = CGPointMake(movingview.center.x, movingview.center.y +5);
if(movingview.center.y ==150)
{
[UIView beginAnimations:@"bounce" context:nil];
[UIView setAnimationRepeatCount:3];
[UIView setAnimationRepeatAutoreverses:YES];
CGAffineTransform transform = CGAffineTransformMakeScale(1.3,1.3);
bt1.transform = transform;
bt2.transform=transform;
[UIView commitAnimations];
}
}
请帮我变成跳跃效果(垂直)?
最佳答案
试试这个。您可以进行一些更改以适合您的需要,
CABasicAnimation *anim = [CABasicAnimation animationWithKeyPath:@"transform"];
anim.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];
anim.duration = 0.125;
anim.repeatCount = 1;
anim.autoreverses = YES;
anim.removedOnCompletion = YES;
anim.toValue = [NSValue valueWithCATransform3D:CATransform3DMakeScale(1.2, 1.2, 1.0)];
[senderView.layer addAnimation:anim forKey:nil];
希望这可以帮助。
