如何使UIViewController重新加载视图? [英] How to make UIViewController re-load the view?

问题描述

我的视图控制器设置为从Nib文件加载视图.在viewDidAppear的某个点上，我可能会更改self.view，并且视图可能会消失，下一次viewDidAppear，我可能决定从笔尖加载原始视图，我该怎么做?

My view controller is set to load the view from Nib file. At some point in viewDidAppear I may change the self.view and the view may disappear, next time viewDidAppear I may decide to load original view from the nib, how would I do that?

推荐答案

一种方法是简单地在viewDidAppear中重新初始化控制器属性对象:

One way to do it is to simply re-initialize your controller property object in the viewDidAppear:

[self setMySubViewController:[[[MySubViewController alloc] initWithNibName...] autorelease]];

您的mySubViewController属性将释放视图控制器的上一个副本，并保留新的副本.

Your mySubViewController property will release the previous copy of the view controller and retain the new one.

希望这会有所帮助.
