Answer 1

#import "MBProgressHUD.h" 

在.H

-(UIView *)viewForIndicator 
{ 
    //UIWindow *__autoreleasing win = [UIApplication sharedApplication].keyWindow; 
    //UIView *__autoreleasing view = [win.subviews lastObject]; 
    //return view; 

    UIWindow *__autoreleasing win = nil;//[UIApplication sharedApplication].keyWindow; 
    NSArray* arrWindows = [UIApplication sharedApplication].windows; 
    for (UIWindow* w in arrWindows) { 
     if ([w isKindOfClass:[UIWindow class]]) { 
      win = w; 
      break; 
     } 
    } 
    UIView *__autoreleasing view = nil; 
    for(int i=(int)[win.subviews count]-1;i>=0;i--){ 
     view=[win.subviews objectAtIndex:i]; 
     if(![view isKindOfClass:[UIAlertView class]]){ 
      break; 
     } 
    } 
    return view; 

} 

然后用它来显示

[MBProgressHUD showHUDAddedTo:[self viewForIndicator] animated:YES];
