iOS將視圖以編程方式自動佈局爲子視圖衝突約束

2故事板中定義的視圖控制器。

我有一個自定義的segue，通過在第一個vc上激活一個控件來觸發。

在-(void)perform方法的segue，我不得不添加第二個vc的視圖作爲子視圖與第一個動畫。

-(void)perform{  

    MyVC *myVC = self.destinationViewController; 
    UIViewController *sourceVC = self.sourceViewController; 

    UIView *myView = myVC.view; 

    [sourceVC.view addSubview:myView]; 

    NSDictionary *viewDictionary = NSDictionaryOfVariableBindings(sourceVC.view, drawerView); 

    [myView addConstraints:[NSLayoutConstraint constraintsWithVisualFormat:@"[myView(200)]" 
options:0 metrics:nil views:viewDictionary]]; 


}

不幸的是我得到以下錯誤。

2014-10-31 16:57:33.899 ReviewsAgain[19971:5435238] Unable to simultaneously satisfy constraints. 
    Probably at least one of the constraints in the following list is one you don't want. Try this: (1) look at each constraint and try to figure out which you don't expect; (2) find the code that added the unwanted constraint or constraints and fix it. (Note: If you're seeing NSAutoresizingMaskLayoutConstraints that you don't understand, refer to the documentation for the UIView property translatesAutoresizingMaskIntoConstraints) 
(
    "<NSLayoutConstraint:0x7fb0306368c0 H:[UIView:0x7fb0306337e0(200)]>", 
    "<NSLayoutConstraint:0x7fb030635c80 'UIView-Encapsulated-Layout-Width' H:[UIView:0x7fb0306337e0(375)]>" 
)

我相信這裏發生的一切 - myView已應用在編譯的時候它的約束「從自己的vc`，當我把它作爲一個子視圖添加到另一個觀點 - 事情變得混亂和無法理解這就限制了應用 - 先前應用的那些 - 或我定義的那些。

我想知道解決這個問題的正確方法是什麼？

所以爲了這個工作view是從其自己viewController'採取'必須有其setTranslatesAutoresizingMaskIntoConstraints設置爲NO。

[myView setTranslatesAutoresizingMaskIntoConstraints:NO];
