can we use viewController view in NSObject?

Question

myObject.h

@interface serverBaglantisi : NSObject<MBProgressHUDDelegate> {
    MBProgressHUD *HUD;
}

myObject.m

-(void) callHud:(NSString*)text{

    HUD = [[MBProgressHUD alloc] initWithView:self.view]; // here 

    [self.view addSubview:HUD];// here
    HUD.delegate = self;
    HUD.labelText = text;
    [HUD showWhileExecuting:@selector(myProgressTask) onTarget:self withObject:nil animated:YES];
}

I am also use MBProgressHud class. If i add "callHud" method in viewController.m(and also add myProgressTask to in viewController.m) then everything works. But I wonder if it is possible to call inside my NSObject successfully?

Sorry for noob question i am new at iOS developer.

Np, you can't. NSObject does not a define a property called view. But you can pass the view controller to the object:

 - (void)showHudWithMessage:(NSString*)text fromViewController:(UIViewController *)viewController
 {
      HUD = [[MBProgressHUD alloc] initWithView:viewController.view]; 
      [viewController.view addSubview:HUD];
      HUD.delegate = self;
      HUD.labelText = text;
      [HUD showWhileExecuting:@selector(myProgressTask) onTarget:self withObject:nil animated:YES];    
 }
