I have a UITableViewController
that I need to add an activity indicator view to. I want the activity indicator to animate until the tableview has loaded. I've tried [self.view addSubview:self.activityIndicator];
but it doesn't appear. What should the activity indicator's parent view be?
I'm not sure which part of this solved my problem, but I think it was giving the activity indicator view a frame that fixed it.
UIActivityIndicatorView *activityIndicator = [[UIActivityIndicatorView alloc] initWithFrame:CGRectMake(0, 0, 40, 40)];
activityIndicator.center = self.view.center;
[self.view addSubview:activityIndicator];
[activityIndicator startAnimating];
