Can I change the size of UIActivityIndicator?

Whatever size i give to it while allocation, it shows fixed size only. Is it possible to increase it?

Code:

activityIndicator = [[UIActivityIndicatorView alloc] initWithFrame:
                     CGRectMake(142.00, 212.00, 80.0, 80.0)];
[[self view] addSubview:activityIndicator];
[activityIndicator sizeToFit];
activityIndicator.autoresizingMask = (UIViewAutoresizingFlexibleLeftMargin |
                                      UIViewAutoresizingFlexibleRightMargin |
                                      UIViewAutoresizingFlexibleTopMargin |
                                      UIViewAutoresizingFlexibleBottomMargin);
activityIndicator.hidesWhenStopped = YES;
activityIndicator.activityIndicatorViewStyle = UIActivityIndicatorViewStyleWhiteLarge;
Solution

  • The size is fixed by the style. It's a standardized interface element so the API doesn't like to fiddle with it.

    However, you probably could do a scaling transform on it. Not sure how that would affect it visually, however.

    Just from a UI design perspective, its usually better to leave these common standardized elements alone. User have been taught that certain elements appear in a certain size and that they mean specific things. Altering the standard appearance alters the interface grammar and confuses the user.
