根據(jù)MBProgressHUD版本不同舉例以下兩種方法解決：
方法一：
MBProgressHUD *hud = [MBProgressHUD showHUDAddedTo:KeyWindow.rootViewController.view animated:YES]; ;
hud.mode = MBProgressHUDModeText;
hud.detailsLabel.font = [UIFont boldSystemFontOfSize:16];
hud.detailsLabel.text= string;
hud.removeFromSuperViewOnHide = YES;
[hud hideAnimated:YES afterDelay:1.5];
方法二：
MBProgressHUD *hud = [MBProgressHUD showHUDAddedTo:KeyWindow.rootViewController.view animated:YES]; ;
hud.mode = MBProgressHUDModeText;
hud.detailsLabelText= @"感謝您的反饋双揪，我們已經(jīng)收到惧蛹！";
hud.detailsLabelFont = [UIFont boldSystemFontOfSize:16];
hud.removeFromSuperViewOnHide = YES;
[hud hide:YES afterDelay:1.5];
