我想在动画期间动画UIView的当前位置,我正在使用此代码。

CABasicAnimation * m_pAnimationObj = [CABasicAnimation animationWithKeyPath:@"transform.translation"];
[m_pAnimationObj setFromValue:[NSValue valueWithCGPoint:CGPointMake(0,-50)]];
[m_pAnimationObj setToValue:[NSValue valueWithCGPoint:CGPointMake(0,[UIScreen mainScreen].bounds.size.height+100)]];
m_pAnimationObj.duration = 2.0;
m_pAnimationObj.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];
[DropImage.layer addAnimation:m_pAnimationObj forKey:@"animations"];

如果有人知道,请回答。 提前谢谢!

使用此代码:

CGRect currentCenter = [drawingView.layer.presentationLayer center];

CGRect currentFrame = [DropImage.layer.presentationLayer frame];
