UIActivityIndicatorView not appearing in Subview - ios

Question

So previously in my application, I had an UIActivityIndicatorView for processes that let the User know that something is loading. I wanted to add a layer of text to inform the user such as signing up,retrieving data, etc. I created a UIView, set it's frame to be in the center of the screen, than my hope was to create the UIActivityIndicatorView in the center and the UILabel in the bottom fourth. My label appears as planned, however now my UIActivityIndicatorView does not appear anymore so I'm curious to as why. I have made sure that the UIActivityIndicatorView is white so it's visible against the black background color and checked other common pitfalls. It seems I'm not understanding something and I was curious if someone could point me in the right direction. Thanks
/*Create the UIView that will serve as the frame to our label and activity view*/
UIView *indicatorFrame=[[UIView alloc]initWithFrame:CGRectMake(self.view.frame.size.width/2-50, (self.view.frame.size.height-self.navigationController.navigationBar.frame.size.height-self.tabBarController.tabBar.frame.size.height)/2.0-50, 100, 100)];
indicatorFrame.backgroundColor=[UIColor blackColor];
indicatorFrame.layer.borderColor=[[UIColor whiteColor]CGColor];
indicatorFrame.layer.borderWidth=2.0f;
indicatorFrame.layer.cornerRadius=10.0f;
indicatorFrame.layer.masksToBounds=YES;
[self.view addSubview:indicatorFrame];
/*Create activity indicator*/
UIActivityIndicatorView *spinner=[[UIActivityIndicatorView alloc]initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleWhiteLarge];
[spinner setCenter:CGPointMake(indicatorFrame.frame.size.width/2.0,indicatorFrame.frame
.size.height/2)];
[indicatorFrame addSubview:spinner];
/*Create Text Label to be added to the indicatorFrame*/
UILabel *indicatorViewText=[[UILabel alloc]initWithFrame:CGRectMake(5,indicatorFrame.frame.size.height/2,indicatorFrame.frame.size.width-5,30)];
[indicatorViewText setCenter:CGPointMake(indicatorFrame.frame.size.width/2,(indicatorFrame.frame.size.height)*3/4)];
indicatorViewText.text=#"Logging In";
indicatorViewText.font=[UIFont fontWithName:#"Georgia" size:18];
indicatorViewText.numberOfLines=1;
indicatorViewText.textColor=[UIColor whiteColor];
indicatorViewText.textAlignment=NSTextAlignmentCenter;
indicatorViewText.adjustsFontSizeToFitWidth=YES;
[indicatorFrame addSubview:indicatorViewText];
[spinner startAnimating];

Tried your code and it works without a problem. Your problem could be somewhere else in the rest of your view controller.

However, the only change i did is to make the text visible by settings its background color to clear color.
My personal opinion however, is to use a library like MBProgressHUD or JGProgressHUD. They cut down your code drastically and you do not have to worry about these kind of problems.
