How to add a UIView above the current UITableViewController

Question

I have difficulty adding a subview (UIView) from within the viewDidLoad method of a UITableViewController

This works:

[self.view addSubview:self.prog         


        

Answer 1

I had a similar problem where I wanted to add a loading indicator on top of my UITableViewController. To solve this, I added my UIView as a subview of the window. That solved the problem. This is how I did it.

-(void)viewDidLoad{
    [super viewDidLoad];
    //get the app delegate
    XYAppDelegate *delegate = [[UIApplication sharedApplication] delegate];

    //define the position of the rect based on the screen bounds
    CGRect loadingViewRect = CGRectMake(self.view.bounds.size.width/2, self.view.bounds.size.height/2, 50, 50);
    //create the custom view. The custom view is a property of the VIewController
    self.loadingView = [[XYLoadingView alloc] initWithFrame:loadingViewRect];
    //use the delegate's window object to add the custom view on top of the view controller
    [delegate.window addSubview: loadingView]; 
}
