THEOS/iPhone越獄編程 - 我應該如何從ViewController隱藏視圖？

Question

我試圖編程的Cydia的修改並應掛鉤，同時加載一個視圖控制器類和隱藏的觀點 - 我已經試過如下：

Tweak.xm：

%hook ScoresViewController 

- (void)viewWillAppear:(BOOL)fp8 { 
    %orig; 

    self.view.hidden = YES; 
} 

%end 

但不幸的是，當試圖使用THEOS「製作」Tweak，我得到以下內容：

Making all for tweak scoresenhancer... 
Preprocessing Tweak.xm... 
Compiling Tweak.xm... 
Tweak.xm: In function 'void  _logos_method$_ungrouped$ScoresViewController$viewWillAppear$(ScoresViewController*, objc_selector*, BOOL)': 
Tweak.xm:49: error: request for member 'view' in 'self', which is of non-class type 'ScoresViewController*' 
Tweak.xm: In function 'void _logos_method$_ungrouped$ScoresViewController$viewWillAppear$(ScoresViewController*, objc_selector*, BOOL)': 
Tweak.xm:49: error: request for member 'view' in 'self', which is of non-class type 'ScoresViewController*' 
lipo: can't figure out the architecture type of: /var/tmp//ccFsVzMR.out 
make[2]: *** [obj/Tweak.xm.o] Error 1 
make[1]: *** [internal-library-all_] Error 2 
make: *** [scoresenhancer.all.tweak.variables] Error 2 

我會感謝您的協助。 我也想知道如何到達定製類的ivars（即：ScoresViewController）。

沒有什麼能告訴編譯器ScoresViewController是一個UIViewController後代。有幾件事你可以在這裏做。

[(UIViewController *)self view].hidden = YES; 

或

@interface ScoresViewController : UIViewController @end 
... 
self.view.hidden = YES;
