objective-c – 为什么在更改其anchorPoint之后设置框架时,我的视图会移动？

接下来,我将uiLabel2的框架重设为我创建的框架：(100,100,20).

当我运行应用程序时,uiLabel1和uiLabel2显示在不同的位置.为什么？

UILabel *uiLabel1 = [[[UILabel alloc] initWithFrame:CGRectMake(100,20)] autorelease];
uiLabel1.text = @"UILabel1";
uiLabel1.layer.anchorPoint = CGPointMake(1,1);

UILabel *uiLabel2 = [[[UILabel alloc] initWithFrame:CGRectMake(100,20)] autorelease];
uiLabel2.text = @"UILabel2";
uiLabel2.layer.anchorPoint = CGPointMake(1,1);
uiLabel2.frame = CGRectMake(100,20);

[self.view addSubview:uiLabel1];
[self.view addSubview:uiLabel2];
