My problem is I have a Custom button and ImageView to which I added the Image.I made this imageView to the custom button as a subview.when Im running it in simulator it workin fine,but when Im runnig it in Device it was not displaying the image in the button.

我的问题是我有一个自定义按钮和ImageView，我在其中添加了图像。我将这个imageView设为自定义按钮的子视图。当我在模拟器中运行时，它运行得很好，但是当我在设备中运行时，它并没有在按钮中显示图像。

I written the code as:

我将代码写成:

In cellForRowtIndexPath

在cellForRowtIndexPath

- (UITableViewCell *)tableView:(UITableView *)tv cellForRowAtIndexPath:(NSIndexPath *)indexPath
{

 UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"MasterViewIdentifier"];
 if (cell == nil) 
 {

  cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:@"MasterViewIdentifier"] autorelease];
  cell.selectionStyle = UITableViewCellSelectionStyleNone;

  UIView* elementView =  [[UIView alloc] initWithFrame:CGRectMake(20,170,320,280)];
  elementView.tag = 0;
  elementView.backgroundColor=[UIColor clearColor];
  [cell.contentView addSubview:elementView];
  [elementView release];

 }
 UIView* elementView  = [cell.contentView viewWithTag:0];
 elementView.backgroundColor=[UIColor clearColor];
 for(UIView* subView in elementView.subviews)
 {
  [subView removeFromSuperview];
 }
         if(indexPath.section == 8)
   {
            imageView.image = [UIImage imageNamed:@"yellow_Star.png"];
            MyCustomButton *button1 = [[MyCustomButton alloc]initWithRating:1];  
  [button1 setFrame:CGRectMake(159, 15, 25, 20)];
  [button1 setShowsTouchWhenHighlighted:YES];
  [button1 addTarget:self action:@selector(buttonAction:) forControlEvents:UIControlEventTouchUpInside];
  [button1 addSubview:imageView];
  [elementView addSubview:button1];
  [button1 release];
  [imageView release];
         }
return cell;
}

and in my buttonAction:

在我buttonAction:

-(void)buttonAction:(MyCustomButton*)sender
{
 rating = [sender ratingValue];
 event.eventRatings = rating;
 [tableView reloadData];

}

and i MyCustomButton class: i have a method as

我有一个方法a

-(MyCustomButton*) initWithRating:(NSInteger)aRatingValue
{
 if (self = [super init])
 {
  self.ratingValue = aRatingValue;
 }
 return self;
}

You're trying to load image named "yellow_Star.png" - check if it actually named so (with the same characters case). File system on iPhone is case sensitive and on Mac OS is not - so it is often causes such problems and file names is the first thing to look at.

您正在尝试加载名为“yellow_Star”的图像。-检查它是否真的命名为这样(使用相同的字符案例)。iPhone上的文件系统是区分大小写的，而Mac OS上的文件系统则不是——因此它经常会导致这样的问题，文件名是首先要考虑的。

Edit: You can also try to check if the image is present in the application bundle - may be it was removed from copy resources build step by chance, that is your image must be in a "Copy Bundle Resources" build step for your build target. If it is absent you can just drag and drop your image there.

编辑:您还可以尝试检查应用程序包中的图像是否存在——可能是由于复制资源构建步骤被删除，这是您的映像必须在“复制包资源”构建步骤中为您的构建目标构建步骤。如果没有，你可以拖放你的图像到那里。
