Iphone Swift-自定义键盘高度,iphone,swift,ios8,Iphone,Swift,Ios8,我用xib文件创建了一个自定义键盘。它工作得很好，我想显示，但我在调试键盘时收到很多警告。。我在xib中创建了所有约束，并将其作为子视图添加到我的视图中 var nib = UINib(nibName: "Keyboard", bundle: nil) let objects = nib.instantiateWithOwner(self, options: nil) mainView = objects.first as UIView view.addSubview(mainView) 我在

我用xib文件创建了一个自定义键盘。它工作得很好，我想显示，但我在调试键盘时收到很多警告。。我在xib中创建了所有约束，并将其作为子视图添加到我的视图中

var nib = UINib(nibName: "Keyboard", bundle: nil)
let objects = nib.instantiateWithOwner(self, options: nil)
mainView = objects.first as UIView
view.addSubview(mainView)

我在viewDidLoad（）方法中执行此操作。在ViewDidDisplay（）中，我调用此函数来获取我的身高：

let heightConstraint = NSLayoutConstraint(item: self.view, attribute: .Height, relatedBy: .Equal, toItem: nil, attribute: .NotAnAttribute, multiplier: 0.0, constant: 180.0)
        view.addConstraint(heightConstraint)

mainView.frame = view.bounds

但现在我得到了这样的警告：

    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:0x178087e40 'UIView-Encapsulated-Layout-Height' V:[UIInputView:0x15e607830(264)]>",
    "<NSLayoutConstraint:0x1780882f0 V:[UIInputView:0x15e607830(180)]>"
)

Will attempt to recover by breaking constraint 
<NSLayoutConstraint:0x178087e40 'UIView-Encapsulated-Layout-Height' V:[UIInputView:0x15e607830(264)]>

Make a symbolic breakpoint at UIViewAlertForUnsatisfiableConstraints to catch this in the debugger.
The methods in the UIConstraintBasedLayoutDebugging category on UIView listed in <UIKit/UIView.h> may also be helpful.

2014-09-17 12:21:21.689 Hodor[6629:1086407]无法同时满足约束条件。
可能下面列表中至少有一个约束是您不想要的。试着这样做：（1）看看每个约束，试着找出你不期望的约束；（2） 找到添加了不需要的约束的代码，然后修复它。（注意：如果您看到不理解的NSAutoresizingMaskLayoutConstraints，请参阅UIView属性TranslatesAutoResizingMaskToConstraints的文档）

将尝试通过打破约束进行恢复
在UIViewAlertForUnsatifiableConstraints处创建一个符号断点，以便在调试器中捕获该断点。
中列出的UIView上UIConstraintBasedLayoutDebugging类别中的方法也可能会有所帮助。

这是什么意思？从警告的文本来看，似乎与高度限制有关…

与限制存在一些冲突。自动调整大小与已应用的约束冲突

试试这个

view.setTranslatesAutoResizengMaskintoConstraints（false） view.addConstraint（NSLayoutConstraint( 项目：主视图，属性：。左侧， relatedBy:。相等，toItem:view，属性：nslayouttribute.Left，乘数：0.6，常数：0）

你能从XIB发布你的约束和布局的截图吗？看起来有一个约束使键盘的显式高度为180点。但是，似乎包含superview的另一个约束（从距离到顶部+从距离到底部，等等）正试图将其设置为264。有分析这些错误经验的人可能能够缩小范围。因此，以下是布局：我所做的限制：-下一个按钮位于左下角，大小固定为60x60-左按钮位于右上角，有一个固定的宽度60和相同的高度作为向下按钮-向下按钮是在右下角，也有一个固定宽度为60，并具有相同的高度与左按钮-大按钮在中间，如果固定到左边，右边，上部和按钮框架的距离为0。xib中的视图本身为320x180，键盘的高度应为180…请查看@skyline75489中的[接受答案][1]。它起作用了！[1] ：您能否从XIB发布约束和布局的屏幕截图？看起来有一个约束使键盘的显式高度为180点。但是，似乎包含superview的另一个约束（从距离到顶部+从距离到底部，等等）正试图将其设置为264。有经验分析这些错误的人可能能够缩小范围。因此，以下是布局：我所做的限制：-下一步按钮位于
