我想在通过 NSURL 字符串上传期间使用 MBProgressHUD 显示一条消息。所以我编码：

MBProgressHUD *hud1 = [MBProgressHUD showHUDAddedTo:self.view animated:YES]; 
hud1.labelText = @"sending info ..."; 
hud1.minShowTime =10.0;

NSURL *url =[NSURL URLWithString:self.urlToUpload];

10 秒时间是为了等待一段时间，我希望用户等待。它有效，但是当第一个消失时我会显示另一条消息。使用另一个：

MBProgressHUD *hud2 = [MBProgressHUD showHUDAddedTo:self.view animated:YES]; 
hud2.labelText = @"SENT!"; 
hud2.minShowTime =2.0;

它没有用，因为此消息与第一个消息重叠。有什么建议吗？

我会删除您-connectionDidFinishLoading方法中的第一个 HUD，或者在您收到字符串已成功上传的通知的任何地方。

[MBProgressHUD hideHUDForView:self.view animated:YES];

然后您可以添加下一个 HUD 1-2 秒。仅通过特定时间添加它，无法在下一个显示之前准确删除第一个 HUD。

这取自MBProgressHUD演示项目。我会用它来显示你的定时完成 HUD。

HUD = [[MBProgressHUD alloc] initWithView:self.navigationController.view];
[self.navigationController.view addSubview:HUD];

// The sample image is based on the work by http://www.pixelpressicons.com, http://creativecommons.org/licenses/by/2.5/ca/
// Make the customViews 37 by 37 pixels for best results (those are the bounds of the build-in progress indicators)
HUD.customView = [[[UIImageView alloc] initWithImage:[UIImage imageNamed:@"37x-Checkmark.png"]] autorelease];

// Set custom view mode
HUD.mode = MBProgressHUDModeCustomView;

HUD.delegate = self;
HUD.labelText = @"Completed";

[HUD show:YES];
[HUD hide:YES afterDelay:3];

+(void)toast:(NSString*) str view:(UIView*)view delegate:(id)delegate  type:(IconType)type{

    [MBProgressHUD hideHUDForView:view animated:YES];

    MBProgressHUD * HUD = [[MBProgressHUD alloc] initWithView:view];
    [view addSubview:HUD];

    NSString* strImage;
    switch (type) {
        case kNone:
            strImage=nil;
            break;
        case kOK:
            strImage=@"37x-Checkmark.png";//NSString stringWithFormat:@"%@",
            break;
        case kError:
            strImage=@"ic_cancel_white_24dp.png";//NSString stringWithFormat:@"%@",
            break;
        default:
            break;
    }

    HUD.customView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:strImage] ];

    // Set custom view mode
    HUD.mode = MBProgressHUDModeCustomView;

    HUD.delegate = delegate;
    HUD.labelText = str;
    HUD.userInteractionEnabled = NO;

    [HUD show:YES];
    [HUD hide:YES afterDelay:1.5f];
}
