我试图加我在项目中加入图片我用下面的代码为它

UIView *selectionView = [[UIView alloc] initWithFrame:CGRectMake(0, 7, 320, 50)]; 
    [selectionView setBackgroundColor: [UIColor clearColor]]; 

    UIImage *image = [[UIImage alloc]init]; 
    image = [UIImage imageWithContentsOfFile:@"PlaceHolder.png"]; 
    UIImageView* blockView = [[UIImageView alloc] initWithImage:image]; 
    blockView.frame = CGRectMake(0, -5, 45, 45); 

    if([[[_arrayForTable valueForKey:@"URL"] objectAtIndex:[indexPath row]] isEqualToString:@"No Image"]) 
    { 


     [selectionView addSubview:blockView]; 


    } 
    else 
    { 
     NSString *path = [[_arrayForTable valueForKey:@"URL"] objectAtIndex:[indexPath row]]; 

     NSURL *url = [NSURL URLWithString:path]; 
     AsyncImageView *imageView = [[[AsyncImageView alloc] init] autorelease];

Answer 1

UIImage *image = [UIImage imageNamed:@"PlaceHolder.png"]; 
UIImageView* blockView = [[UIImageView alloc] initWithImage:image]; 

/* 
imageNamed: is to load the picture which is in bundle. pass in the picture name 
imageWithContentsOfFile: need to pass in the whole address of the file 
*/ 

Answer 2

尝试

UIImage *image = [UIImage imageNamed:@"yourfile.png"]; 

并将图像添加到imageView并检查图像文件是否已添加到您的项目中
