首先，你需要的Alloc初始化它如下圖所示

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

然後設置它需要的屬性如下

self.progressHud.labelText = @"Processing Image"; 
self.progressHud.dimBackground = YES; 
self.progressHud.animationType = MBProgressHUDAnimationZoom; 
self.progressHud.delegate = self; 

然後作秀它使用下面的代碼

[self.navigationController.view addSubview:self.progressHud]; 
[self.progressHud show:NO];
