UIViewController

Question

如何理解视图已满载？

Answer 1

The view is fully loaded by the time your UIViewController 's viewDidLoad method is called.

You can also use the isViewLoaded method to determine if the view is currently loaded in memory.

Hmm... can't help but think that's not what you're trying to ask, but that's what you appear to have asked. These are exciting times.

Answer 2

检查UIViewController的-isViewLoaded方法。
