问题描述
我想知道，如何以及何时(viewDidload，viewwillappear，viewDidappear)可以获得自动化以适合其圆形视图的Uiviews框架大小吗?
推荐答案
从您的问题中尚不清楚为什么要它，但我想是要布局您的子视图.幸运的是，苹果知道您想这样做并实施-(void)layoutSubViews请参阅此信息: nes Layoutsubviews notebviews何时称为? a>

我尝试了layoutSubviews，但是它被多次调用，这是一个问题，当我需要自动尺寸的框架以创建CGContext来吸引.
.我使用的解决方案是在我的自定义UIView上公开init方法，以使其父视图控制器在其viewWillAppear中调用.
我希望有一种方法可以在Custom UIView的实施中完成所有操作，但它使我感到不安(以及Google和Apple的文档等).

- (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);
}
问题描述
I wonder, how and when (viewDidLoad, viewWillAppear, viewDidAppear) can I get a UIViews frame size that was autoresized to fit its partent view?
推荐答案
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).
