Iphone 将小图像放在UIImageView的顶部？

我在一个页面中有一个UIImageView，它从Interface builder获取它的图像，我试图在它的顶部放置小图标（这是一个小地图，我想在上面放置图标）。我知道这可能很简单，但我试图在文档中查找它，但这让我更加困惑。

使用Interface Builder，您不能将UIImageView拖动到现有的UIImageView中吗？实际上，您最终将一个UIImageView嵌入到另一个UIImageView中

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该UIImageView

希望这有帮助。祝你好运

您可以通过添加大UIViewImage视图和小UIViewImage视图来构建自己的UIView

下面我用伪代码说明了我的方法

-(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];
}

请尝试以下代码：

UIImageView*backgroundImageView=（UIImageView*）[带标记的自视图：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];
}

我刚刚发现，当您使用IB添加UIImageView时，它会将其视为一个简单的uiview。因此，只需创建新的UIImageView并在其中加载图像，然后将其作为子视图添加到self.view，它就会动态添加到视图中。谢谢，问题是我试图获取不存在的图像视图。。。当我将新的uiimageview添加到self.view时，它开始工作了，谢谢：）我刚刚发现uiimageview应该单独分配，并作为子视图添加到视图中。我想问一下，你错过了为Foreground ImageYeah你有鹰眼。foregroundImageView.frame=CGRectMake（15,15，backgroundImageView.frame.size.width*mPercent/100，foregroundImageView.bounds.size.height）；
