我正在使用MBProgress HUD，但我不知道问题出在哪里。我有一个UIButton显示HUD的。这是我的代码：

- (void)showHUD:(id)sender {
    HUD = [[MBProgressHUD alloc] initWithView:self.view];
    HUD.mode = MBProgressHUDModeCustomView;
    [self.view addSubview:HUD];
    HUD.delegate = self;
    HUD.labelText = @"No Internet Connection...";
    HUD.opacity = 0.7;
    HUD.customView = 
     [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"image.png"]];
    [HUD showWhileExecuting:@selector(hudWasHidden) 
                   onTarget:self 
                 withObject:nil 
                   animated:YES];
}


- (void)hudWasHidden {

    float progress = 0.0f;
    while (progress < 1.0f) {
        progress += 0.01f;
        HUD.progress = progress;
        usleep(50000);
    }
}

这是控制台日志：

这是 Cocoa 代码中常见的崩溃：“无法识别的选择器”在这种情况下非常明确。MBProgressHUD 没有customView属性，尝试设置它会导致崩溃。是这里setCustomView调用的隐式选择器（方法），当调用的方法不存在时，Objective-C 将崩溃。

不知道该告诉您如何完成您正在尝试做的事情。
