iOS将视图以编程方式自动布局为子视图冲突约束

2故事板中定义的视图控制器。

我有一个自定义的segue，通过在第一个vc上激活一个控件来触发。

在-(void)perform方法的segue，我不得不添加第二个vc的视图作为子视图与第一个动画。

-(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错误。

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)]>" 
)

我相信这里发生的一切 - myView已应用在编译的时候它的约束“从自己的vc`，当我把它作为一个子视图添加到另一个观点 - 事情变得混乱和无法理解这就限制了应用 - 先前应用的那些 - 或我定义的那些。

我想知道解决这个问题的正确方法是什么？

所以为了这个工作view是从其自己viewController'采取'必须有其setTranslatesAutoresizingMaskIntoConstraints设置为NO。

[myView setTranslatesAutoresizingMaskIntoConstraints:NO];
