IOS-图像不以编程方式显示

我在代码中设置了图像，但图像不显示。当我在iPhone或模拟器上运行时，图像不会显示

我会给你提供代码

以下是迄今为止的代码：

@implementation ViewController

- (void)viewDidLoad
{
    [super viewDidLoad];

    self.view.backgroundColor = [UIColor colorWithRed:70.0f/255.0f
                                                green:111.0f/255.0f
                                                 blue:162.0f/255.0f
                                                alpha:1.0f];

    UIView *viewTopBar = [[UIView alloc] init];
    [self.view addSubview:viewTopBar];
    viewTopBar.backgroundColor = [UIColor colorWithRed:53.0f/255.0f
                                       green:85.0f/255.0f
                                        blue:127.0f/255.0f
                                       alpha:1.0f];
    viewTopBar.frame = CGRectMake(0,25,320,40);

    UIWebView *viewMusic = [[UIWebView alloc] init];
    [self.view addSubview:viewMusic];
    viewMusic.backgroundColor = [UIColor blackColor];
    viewMusic.frame = CGRectMake(0,65,320,270);
    viewMusic.mediaPlaybackRequiresUserAction=NO;
    viewMusic.allowsInlineMediaPlayback = YES;

    NSBundle* bundle = [NSBundle mainBundle];
    NSString* path = [bundle  pathForResource: @"index" ofType: @"html"];
    NSURL* url = [NSURL fileURLWithPath: path];
    NSURLRequest* req = [NSURLRequest requestWithURL: url];
    [viewMusic loadRequest: req];

    UIImageView *imageFBButton = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"loginfb.gif"]];
    imageFBButton.frame = CGRectMake(43, 421, 234, 49);
    [self.view addSubview:imageFBButton];
}

@end

我试过你的密码。它加载的图像没有任何问题。我相信这是一个糟糕的资源，或者像“雷姆斯”所说的那样缺失。附上屏幕截图。您可以在指定的位置看到google图像

您的资源包中是否有名为“loginfb.gif”的图像？请在

imageFBButton.frame=CGRectMake（43421234，49）处添加断点然后将鼠标悬停在
imageFBButton
上并单击眼睛图标。你看到图像了吗？图像在应用程序中folder@remus它说无法加载ImageFBButton的数据，这是一个坏的资源或丢失。仔细检查是否已添加到目标中？
