objective-c – UIView.center = UIImageView.center,但图像视图似乎并不在景观中心

[imageView setCenter:dynamicMainView.center];

其中imageView是UIImageView(显然:))和dynamicMainView是UIView，但最终结果docent似乎在中心，

视觉表示

在UIView中添加UIImageView的完整方法代码是，

-(void) addImageIntoMainDynamicView:(UIImage *) image
{
    [self clearImageFromMainDynamicView];//Always clear Dynamic main view before adding new views
    imageView = [[UIImageView alloc] initWithImage:image];  
        if(imageView.bounds.size.width > dynamicMainView.bounds.size.width || imageView.bounds.size.height > dynamicMainView.bounds.size.height)
        {
            [imageView setFrame:[dynamicMainView bounds]];
        }

        [imageView setCenter:dynamicMainView.center];
        NSLog(@"Image : X = %f and Y = %f",imageView.center.x,imageView.center.y );
        NSLog(@"UIView : X = %f and Y = %f",dynamicMainView.center.x,dynamicMainView.center.y );
        [dynamicMainView addSubview:imageView];
    [imageView release];
}

以上log值是，

2011-12-21 21:07:11.853 Map1TestApp[94645:11603] UIView : X = 512.000000 and Y = 371.500000

任何关于为什么不添加到中心的线索？我做错了吗？

对于未来的观察者，ANWSER WAS：

[imageView setCenter:CGPointMake(CGRectGetMidX([dynamicMainView bounds]),CGRectGetMidY([dynamicMainView bounds]))];
