Using SCLAlert as HUD

[rjpalermo1]

Noodled around a bit and found an easy way to use this great control as a custom HUD / spinner replacement:

In your class.h file interface:

SCLAlertView *hud;
NSString *hudTitle;
NSString *hudText;

In your class.m file provide these methods:

• (void)startHud {

  [self.view endEditing:YES]; //make sure keyboard is down

  hud = [[SCLAlertView alloc] init];
  [hud setShowAnimationType:SlideInToCenter];
  hud.backgroundType = Blur;
  hud.customViewColor = [UIColor colorWithRed:0.0f green:0.0f blue:0.0f alpha:0.7f]; //set custom color
  [hud setHideAnimationType:SlideOutFromCenter];
  [hud showWaiting:self title:hudTitle
  subTitle:hudText
  closeButtonTitle:nil duration:0];
  }

-(void)stopHud {
[hud setHideAnimationType:SlideOutToCenter];
hudText = @"";
hudText = @"";
[hud hideView];
}

Now wherever you want to invoke the spinner simply:

                    hudTitle = NSLocalizedString(@"Processing Authorization", nil);
                    hudText = NSLocalizedString(@"Communicating with host...", nil);
                    [self startHud];

Wherever you want to hide the spinner:

                   [self stopHud];

Taking this a step further combining with SCAlerts:

                [alert addButton:NSLocalizedString(@"Authorization", nil) actionBlock:^{
                    hudTitle = NSLocalizedString(@"Processing Authorization", nil);
                    hudText = NSLocalizedString(@"Communicating with host...", nil);
                    [self saveObject];   //invoke some method
                    return;
                }];

                [alert addButton:NSLocalizedString(@"Update Application", nil) actionBlock:^{
                    hudTitle = NSLocalizedString(@"Update Application", nil);
                    hudText = NSLocalizedString(@"Communicating with host...", nil);
                    [self updateObject];   //invoke some other method
                    return;
                }];

in your method (saveObject);

-(void)saveObject {
[self startHud];
// do something
[self stopHud];
}
