iPhone - self.view是initWithNibName子零，而viewDidLoad中不叫

Question

我有這樣的級聯：

某處在應用

- (void) go 
{ 
    MyCustomViewController* controller = [[MyCustomViewController alloc] init]; 
    controller.delegate = self; 
    [controller run]; 
} 

在MyCustomViewController

- (id) init 
{ 
    // there is an if statement here in real to choose another XIB if needed 
    // but I only display here the code that is called in my tests 
    self = [super initWithNibName:@"MyXIB" bundle:nil]; 
    if (!self) return nil; 

    self.delegate = nil; 

    return self; 
} 

- (void) run 
{ 
    // do things with self.view 
} 

MyCustomViewController繼承GenericWindowController

在GenericWindowController

/*- (id) initWithNibName:(NSString*)nibNameOrNil bundle:(NSBundle*)nibBundleOrNil 
{ 
    if (!(self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil])) return nil; 

    self.view.userInteractionEnabled = NO; // THE APP CRASHES HERE ! self.view is nil 

    ... 

    return self; 
}*/ 

// METHOD created following first answers : NOT CALLED 
- (void) viewDidLoad 
{ 
    self.view.userInteractionEnabled = NO; 
    // and many other things done with self.view 
} 

MyXIB 有文件的所有者設置爲MyCustomViewController和視圖連接。
包含所有文件並將其檢入到項目中。

GenericWindowController被設計來製作一些標準的東西。
MyCustomViewController將這些東西擴展到MyXIB中設計的自定義視圖。

爲什麼self.view在GenericWindowController中爲零？
爲什麼viewDidLoad不叫？

Answer 1

不可思議!!!問題是因爲XIB缺少本地化。增加了本地化，並且沒有問題了。

Answer 2

self.view僅在viewDidLoad之後有效 - 在init...之內，它仍然是nil。

Answer 3

視圖控制器不應該嘗試訪問其在initWithNibName:bundle:中的視圖。它應該等到viewDidLoad。
