问题描述
我已经尝试理解了几个小时，何时应该使用viewDidload:以及何时应该使用initWithNibName:来设置我的viewController的属性.
I've been trying to understand for hours when I should use the viewDidload: and when I should use initWithNibName: to set up the properties of my viewController.
例如，我正在使用TableViewController，并在initWithNibName中设置了它的所有属性(例如backgroundColor，separateColor，工具栏项).这是正确的方法吗?
For instance, I'm using a TableViewController and I'm setting all its properties (such as the backgroundColor, the separateColor, the toolbar items) in initWithNibName. It is the right way to do ?
如果有人能启发我.
谢谢
推荐答案
您应在viewDidLoad中设置属性.当控制器的视图加载到内存中时，系统会调用此方法.当您从nib文件创建控制器实例时，initWithNibName:是您您调用的.
You should set up your properties in the viewDidLoad. This method is called by the system when the controller's view is loaded into memory. The initWithNibName: is something that you call when you create a controller instance from a nib file.
这就是说，如果您在initWithNibName:中设置属性，然后调用init，则控制器可能不会处于良好状态.因此，最好在viewDidLoad中进行.
That is to say, that if you set up your properties in the initWithNibName: and instead you call init, your controller might not be in a good state; thus, it's best to do in viewDidLoad.
