Question

此问题与我之前询问过如何添加在单独的xib here中定义的视图的问题有关。我仍然在努力解决这个问题，现在我得到了这个特定于布局的错误，所以我觉得最好问一个新问题。

我有2个xib，并且我试图将xib1中的视图插入到xib2上的NSView占位符中，并且我希望在调整视图大小时调整xib1中的视图的大小。 / p>

这是我尝试设置左/右约束的代码。

    let placeholder: NSView = self.m_viewPlaceHolder;
    let insert: NSView = UserView01().view;
    insert.frame = NSRect(x: 0, y: 0, width: placeholder.frame.width, height: placeholder.frame.height);
    placeholder.addSubview(insert);

    NSUserDefaults.standardUserDefaults().setBool(true, forKey: "NSConstraintBasedLayoutVisualizeMutuallyExclusiveConstraints");
    let hor = NSLayoutConstraint.constraintsWithVisualFormat("H:|-[view]-|", options: NSLayoutFormatOptions(rawValue: 0), metrics: nil, views: ["view" : insert]);
    NSLayoutConstraint.activateConstraints(hor);

这是我在跟踪中看到的错误

2016-01-12 20:49:09.307 SubView01[9240:308241] Unable to simultaneously satisfy constraints:
(
"<NSLayoutConstraint:0x608000087800 H:|-(NSSpace(20))-[NSView:0x608000120500]   (Names: '|':NSView:0x6080001206e0 )>",
"<NSAutoresizingMaskLayoutConstraint:0x6000000842e0 h=--& v=&-- H:|-(0)-[NSView:0x608000120500]   (Names: '|':NSView:0x6080001206e0 )>"
)

Will attempt to recover by breaking constraint
<NSLayoutConstraint:0x608000087800 H:|-(NSSpace(20))-[NSView:0x608000120500]   (Names: '|':NSView:0x6080001206e0 )>

Set the NSUserDefault NSConstraintBasedLayoutVisualizeMutuallyExclusiveConstraints to YES to have -[NSWindow visualizeConstraints:] automatically called when this happens.  And/or, break on objc_exception_throw to catch this in the debugger.

)

我在设计器中添加的唯一约束是左/上/右/下0占位符到主窗口的0像素约束，以及标签上的用户视图。

Answer 1

视图的隐式自动调整遮罩存在冲突。

两个选项：

通过关闭AutoLayout，更改掩码并再次启用AutoLayout或取消选中translates autoresizing mask into constraints（如果可用），将掩码设置为适合Interface Builder的内容。
以编程方式执行相同操作设置掩码
```
view.autoresizingMask = [...]
```
或停用translatesAutoresizingMaskIntoConstraints
```
view.translatesAutoresizingMaskIntoConstraints = false
```

Autolayout错误 - 无法同时满足约束
