Question

我尝试使用Swift制作简单的iOS自定义键盘扩展程序。默认的UIView并不能满足我的需求，因此我在this上阅读了问题，我可以使用C中bc属性的故事板。

不幸的是每次我打开键盘时，都会出现以下错误

C.print(B)

堆栈跟踪继续，但这是它的要点。

这就是我所做的一切（我在一个干净的项目中试过这个）。

创建容器应用
创建键盘目标
添加Main.storyboard
将NSExtensionMainStoryboard添加到info.plist
将info.plist的自定义类设置为默认2016-01-18 18:02:56.350 Kappa Keyboard[44790:2959180] Failed to inherit CoreMedia permissions from 44787: (null) 2016-01-18 18:02:56.368 Kappa Keyboard[44790:2959138] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[__NSArrayM insertObject:atIndex:]: object cannot be nil' *** First throw call stack: ( 0 CoreFoundation 0x002f1746 __exceptionPreprocess + 182 1 libobjc.A.dylib 0x01d32a97 objc_exception_throw + 44 2 CoreFoundation 0x001a6ce1 -[__NSArrayM insertObject:atIndex:] + 881 3 CoreFoundation 0x001a6941 -[__NSArrayM addObject:] + 65 4 UIKit 0x00c7d0bd -[UIViewController _addChildViewController:performHierarchyCheck:notifyWillMove:] + 417 5 UIKit 0x00c968aa -[UIViewController(UIContainerViewControllerProtectedMethods) addChildViewController:] + 78 6 UIKit 0x01206db8 -[_UIViewServiceViewControllerOperator __createViewController:withContextToken:fbsDisplays:appearanceSerializedRepresentations:legacyAppearance:traitCollection:initialInterfaceOrientation:hostAccessibilityServerPort:canShowTextServices:replyHandler:] + 2702

知道我错过了什么吗？

Answer 1

将故事板文件添加到键盘目标在键盘目标的常规标签页中，将Main Interface设置为故事板文件，如屏幕截图所示第二个重要的部分是确保将您的KeyboardViewController参考视图的课程更改为UIInputView而不是故事板中的UIView。

Answer 2

我也建立了一个自定义键盘应用程序。以下是步骤：

<强>目标C

创建键盘目标
在目标包中创建一个xib文件（MyKeyboard.xib）
创建cocoa touch类选择UIView（MyKeyboard.h MyKeyboard.m）
在KeyboardViewController.m中，导入MyKeyboard.h
在KeyboardViewController.m中，添加

@property (nonatomic, strong) MyKeyboard *myKeyboard;

viewDidLoad中：

self.myKeyboard = [[MyKeyboard alloc]init];
self.myKeyboard = [[[NSBundle mainBundle] loadNibName: @"MyKeyboard"
                                     owner:self option:nil] objectAtIndex:0];
self.inputView = (UIInputView *)self.myKeyboard;

<强>夫特

创建键盘目标
在目标包中创建一个UIView接口（xib文件）（MyKeyboard.xib）
创建cocoa touch类选择UIInputView（MyKeyboard.swift）
在KeyboardViewController.swift中添加

// here

override func viewDidLoad() {
    super.viewDidLoad()
    // setup your keyboard
    self.myKeyboard = NSBundle.mainBundle().loadNibNamed("MyKeyboard", owner: self, options: nil)[0] as! MyKeyboard
    self.inputView = self.myKeyboard;

    // Perform custom UI setup here
    self.nextKeyboardButton = UIButton(type: .System)
    self.nextKeyboardButton.setTitle(NSLocalizedString("Next Keyboard", comment: "Title for 'Next Keyboard' button"), forState: .Normal)
    self.nextKeyboardButton.sizeToFit()
    self.nextKeyboardButton.translatesAutoresizingMaskIntoConstraints = false
    self.nextKeyboardButton.addTarget(self, action: "advanceToNextInputMode", forControlEvents: .TouchUpInside)

    self.myKeyboard.addSubview(self.nextKeyboardButton) // add the button to self.myKeyboard!!

    let nextKeyboardButtonLeftSideConstraint = NSLayoutConstraint(item: self.nextKeyboardButton, attribute: .Left, relatedBy: .Equal, toItem: self.view, attribute: .Left, multiplier: 1.0, constant: 0.0)
    let nextKeyboardButtonBottomConstraint = NSLayoutConstraint(item: self.nextKeyboardButton, attribute: .Bottom, relatedBy: .Equal, toItem: self.view, attribute: .Bottom, multiplier: 1.0, constant: 0.0)
    self.view.addConstraints([nextKeyboardButtonLeftSideConstraint, nextKeyboardButtonBottomConstraint])
}

这就是它的样子
