Swift - Пользовательская высота клавиатуры

Question

Я создал пользовательскую клавиатуру с xib-файлом. Он отлично работает и показывается, как я хочу, но при отладке клавиатуры я получаю много предупреждений. Я создал все ограничения в xib и добавил его в качестве подзаголовка для моего представления.

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

Я делаю это в видеDidLoad() - метод. В viewDidAppear() Я называю это, чтобы получить мой рост:

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 

Но теперь я получаю это предупреждение:

    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.

Что это значит? Из текста предупреждений кажется что-то с ограничением по высоте ...

Answer 1

Попробуйте

view.setTranslatesAutoresizingMaskIntoConstraints (ложь) view.addConstraint (NSLayoutConstraint ( пункт: MainView, атрибут: .left, relatedBy: .Equal, toItem: вид, атрибут: NSLayoutAttribute.Left, умножитель: 0,6, постоянный: 0))

view.addConstraint(NSLayoutConstraint(
     item:mainView, attribute:.Right, 
     relatedBy:.Equal, toItem:view, 
     attribute:.RightMargin,multiplier:0.6, constant: 0)) 

    view.addConstraint(NSLayoutConstraint(
     item:mainView, attribute:.Width, 
     relatedBy:.Equal, toItem:view, 
     attribute: .Width,multiplier:0.6, constant: 0)) 

    view.addConstraint(NSLayoutConstraint(
     item:mainView, attribute:.Height, 
     relatedBy:.Equal, toItem:view, 
     attribute:.Height,multiplier:0.6, constant: 0)) 

Answer 2

Есть некоторые конфликты с ограничениями. Autoresize противоречит ограничениям, которые вы применили.
