用于UIView的viewDidLoad？ [英] viewDidLoad for UIView?

问题描述

UIView 的 viewDidLoad 是什么？

我有一个带有xib的 UIView 。我想在加载时隐藏其中一个子视图。
我试图使用它。

I have a UIView with xib. I would like to hide one of it's subviews when it is loaded. I tried to use this.

- (id)initWithCoder:(NSCoder *)aDecoder{
    ....
    _theView.hidden = YES;
}

但子视图 _theView 此时为零。

这个答案没有帮助我，因为在创建 UIViewController 的那一刻，还没有创建 UIView 。它是以编程方式创建的，稍后会创建。

This answer didn't help me, becouse at moment of creating the UIViewController, the UIView is not created yet. It is created programaticly, later on.

推荐答案

仅当从nib文件加载视图时才会调用AwakeFromNib 。为所有视图调用
layoutSubviews ，你可以在<$ c中添加bool _loaded = yes; $ c> layoutSubviews 函数并知道视图是否已加载。

AwakeFromNib is called only if the view loaded from nib file. layoutSubviews is called for all views, you can add bool _loaded = yes; in the layoutSubviews function and know if the view loaded.
