Question

I am receiving the following warning in a class extending UIView and have no idea why:

Also, does anyone know what those blue arrows are suppose to represent?

It is initialised using the following function:

- (void)updateIndicators {
    if (indicator) {
        [indicator removeFromSuperview];
    }

    if (mode == MBProgressHUDModeDeterminate) {
        self.indicator = [[[MBRoundProgressView alloc] initWithDefaultSize] autorelease];
    }
    else if (mode == MBProgressHUDModeCustomView && self.customView != nil){
        self.indicator = self.customView;
    } else {
        self.indicator = [[[UIActivityIndicatorView alloc]
                           initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleWhiteLarge] autorelease];
        [(UIActivityIndicatorView *)indicator startAnimating];
    }


    [self addSubview:indicator];
}

Answer 1

If indicator isn’t yet part of the view hierarchy, then its bounds property is going to be useless.

Try this instead…

CGRect indicatorFrame = indicator.frame;
self.width = indicatorFrame.size.width + 2 * margin;
self.height = indicatorFrame.size.width + 2 * margin;
