Interface Builder是否使用-init方法来初始化视图控制器？ [英] Does Interface Builder use the -init method to initialize view controllers?

问题描述

我使用界面构建器设置标签栏控制器，每个标签栏项目链接到视图控制器（4个选项卡，4个视图控制器）。我想知道Interface Builder是否使用 -init 方法来初始化视图控制器，因为显然这个方法不会被调用：

I have setup tab bar controller using interface builder, and each tab bar item is linked to a view controller (4 tabs, 4 view controllers). I want to know if Interface Builder uses an -init method to initialize the view controller because apparently this method does not get called:

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil;

...我想做一些初始化。我不能添加到 -viewDidLoad ，因为它是在内存警告的情况下被调用。任何想法？

... and I want to do some initializations. I can't add that to -viewDidLoad since it is recalled in case of memory warning. Any idea?

推荐答案

从 *（nib | xib）引入：

- (id)initWithCoder:(NSCoder *)inCoder;

所以你可以覆盖或者如果你在 -initWithCoder： / code>被调用不是一个你可以使用的问题：

So you could override that or if doing your setup after -initWithCoder: is called is not a problem you could use:

- (void)awakeFromNib;

。
