我想改变anchorPoint,但保持视图在同一个地方.我试过NSLog-ing分词self.layer.position和self.center他们都保持不变,无论更改anchorPoint的.然而我的观点却在变化
关于如何做到这一点的任何提示？
self.layer.anchorPoint = CGPointMake(0.5, 0.5);
NSLog(@"center point: %f %f", self.layer.position.x, self.layer.position.y);
self.layer.anchorPoint = CGPointMake(1, 1);
NSLog(@"center point: %f %f", self.layer.position.x, self.layer.position.y);
输出是:
2009-12-27 20:43:24.161 Type[11289:207] center point: 272.500000 242.500000
2009-12-27 20:43:24.162 Type[11289:207] center point: 272.500000 242.500000
