How to get frame size after autoresize is done

I wonder, how and when (viewDidLoad, viewWillAppear, viewDidAppear) can I get a UI开发者_如何学GoViews frame size that was autoresized to fit its partent view?

It's not clear from your question why you want it but I imagine it is to layout your sub views. Luckily Apple knew you would want to do that and implemented -(void)layoutSubViews see this: When is layoutSubviews called?

I tried layoutSubviews, but it gets called more than once which is a problem when I need the auto sized frame in order to create a CGContext to draw into.

The solution I used was to expose an init method on my custom UIView for its parent view controller to call in its viewWillAppear.

I wish there was a way to accomplish this all within the custom UIView's implementation, but it eludes me (and Google and Apple's docs and SO).

- (void)viewDidAppear:(BOOL)animated {
    CGFloat uIViewWidth = self.uIView.bounds.size.width;
    CGFloat uIViewHeight = self.uIView.bounds.size.height;
    CGRect uIViewSize = CGRectMake(0, 0, uIViewWidth, uIViewHeight);
}

    NSLog(@"%f; %f; %f; %f;", yourView.frame.origin.x, yourView.frame.origin.y, yourView.frame.size.width, yourView.frame.size.height);

this is how you can get frame of your view
