原标题:How To Create A Center Point At UIImageview

“entergraph

Hi Guys I am trying to rotate a UIImageview from the Black dot on this image. what is happening now is that the center is not changing I have tried like this.

Image.Center = CGPointmake(37.3,150);

当我打电话时,这树立了正确的形象。

感谢!

最佳回答

您需要加入这一法典:

    imageView.layer.anchorPoint = CGPointMake(0.5,0.5);
[UIView beginAnimations:@"rotate" context:nil];

imageView.transform = CGAffineTransformMakeRotation(angle);
[UIView commitAnimations];
