objective-c – 当我设置锚点时,我的图像没有加载

我有一个UIView,我正在加载我的图像视图作为子视图.当我没有设置锚点时图像显示,但每当我设置锚点时图像都没有显示.我还添加了QUARTZCore框架工作.

我在下面添加我的代码

CGRect apprect=CGRectMake(0,1024,768);
UIView *containerView = [[UIView alloc] initWithFrame:apprect1];
containerView.BACkgroundColor = [UIColor whiteColor];
[self.view addSubview:containerView];

handleView1= [[UIImageView alloc] initWithImage:[UIImage imagenamed:@"large.gif"]];
[handleView1 setAlpha:1];
//[handleView1 setFrame:CGRectMake(390,172.00,56.00,316.00)];
handleView1.userInteractionEnabled = YES;
handleView1.layer.anchorPoint=CGPointMake(490.0,172.0);
[containerView addSubview:handleView1];
