Why is my UIActivityIndicatorView is not centered on screen?

activityIndicator = [[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleWhiteLarge];
        activityIndicator.center = CGPointMake(self.view.bounds.size.width / 2.0f, self.view.bounds.size.height / 2.0f);

Presently it appears in the bottom half.

Set center in viewDidLayoutSubviews.

- (void) viewDidLayoutSubviews {
self.myActivityIndicator.center = self.view.center; }

Thanks :)

why not just this way

activityIndicator.center =  self.view.center;

activityIndicator.autoresizingMask = (UIViewAutoresizingFlexibleRightMargin | UIViewAutoresizingFlexibleLeftMargin | UIViewAutoresizingFlexibleBottomMargin | UIViewAutoresizingFlexibleTopMargin)

this is working well without having to do those calculations as mentioned by others

If you are adding indicator to parentView following logic should center the indicator on parent - It works for me.

 // ...
 CGSize parentSize = parentView.frame.size;
 UIActivityIndicatorView *activityIndicator = [[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleWhite];
 activityIndicator.center = CGPointMake(parentSize.width/2, parentSize.height/2);
 // ...

This will put the indicator in the center of your view (not the screen!):

activityIndicator.center = CGPointMake(self.view.bounds.size.width / 2.0f, self.view.bounds.size.height / 2.0f);
activityIndicator.autoresizingMask = (UIViewAutoresizingFlexibleRightMargin | UIViewAutoresizingFlexibleLeftMargin | UIViewAutoresizingFlexibleBottomMargin | UIViewAutoresizingFlexibleTopMargin)

The autoresizing keeps in in the center when its size changes (e.g. when switching screen orientation).

If it doesn't work, your problem is somewhere else. Try to log the size of your view, maybe it is not positioned correctly?

NSLog(@"View frame: %@", NSStringFromCGRect(self.view.frame));

You can do it this way:

activityIndicator = [[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleWhiteLarge];
    activityIndicator.frame = CGRectMake(self.view.bounds.size.width / 2.0f - activityIndicator.frame.size.width /2.0f, self.view.bounds.size.height / 2.0f - activityIndicator.frame.size.height /2.0f, activityIndicator.frame.size.width, activityIndicator.frame.size.height);
//then add to the view
