把小图像放在UIImageView的顶部？-PutsmallimagesonthetopofUIImageView?

Using Interface Builder, can't you just drag a UIImageView into an existing UIImageView? In effect, you end up with one UIImageView embedded within another.

使用Interface Builder，你不能只是将UIImageView拖入现有的UIImageView吗？实际上，您最终将一个UIImageView嵌入另一个UIImageView中。

You should also be able to easily set the hidden property of the "small map" UIImageView in code, depending on if that UIImageView is needed or not.

您还应该能够在代码中轻松设置“小地图”UIImageView的隐藏属性，具体取决于是否需要UIImageView。

Hope this helps. Good Luck.

希望这可以帮助。祝你好运。

you could compose your own UIView by adding both the large and small UIViewImage views.

你可以通过添加大型和小型UIViewImage视图来编写自己的UIView。

I have illustrated my approach below with the Pseudocode .

我已经用Pseudocode说明了我的方法。

-(id) initwithFrame:(CGRect) frame
{

  if(self = [super initWithFrame:frame])
  {

   iCOntainer= [[UIView alloc] initWithFrame:frame];

   [iContainer addSubViews:iLargerUIImageView];
   [iContainer addSubViews:iSmallUIImageView];

   [self.view addSubViews:iContainer];
  }
  return self;
}
-(void) layoutSubviews
{
    CGRect myRect = self.frame;
    iContainer.frame = myRect;
    //Give the location to iLargerUIImageView as per your requirement.
     iLargerUIImageView.frame = CGRectMake(...,...,...,...);
    //Give the location to iSmallUIImageViewas per your requirement.  
    iSmallUIImageView.frame = CGRectMake(...,...,...,...);

}

-(void) dealloc
{
  [iContainer release];
  [iLargerUIImageView release];
  [iSmallUIImageView release];
}

try this code:

试试这段代码：

UIImageView *backgroundImageView = (UIImageView *)[self viewWithTag:kBckGndImag];

UIImageView * backgroundImageView =（UIImageView *）[self viewWithTag：kBckGndImag];

if(!backgroundImageView){
    UIImage *imageName  =   [UIImage imageNamed:kpointsChartBig];

    backgroundImageView =   [[UIImageView alloc] initWithFrame:CGRectMake(15, 15, imageName.size.width, imageName.size.height)]; 

    backgroundImageView.image=imageName;

    [backgroundImageView setTag:kBckGndImag];

    [pointImageView addSubview:backgroundImageView];

    [backgroundImageView release];
}

UIImageView *foregroundImageView = (UIImageView *)[self viewWithTag:kForGndImage];

if(!foregroundImageView){
    foregroundImageView =       [[UIImageView alloc] initWithImage:[UIImage imageNamed:kpointsColoredChartBig]];

    foregroundImageView.cOntentMode= UIViewContentModeLeft;

    foregroundImageView.clipsToBounds = YES;

    [pointImageView addSubview:foregroundImageView];

    [foregroundImageView release];
}
