iOS 8自定義鍵盤的庫：Slidden

Slidden 是開源，可定制的，使用 Swift 編寫的 iOS 8 鍵盤。利用這個開源庫，可以方便的配置鍵位、顏色以及鍵位對應的圖片。當然，如果你想學習如何一步一步開發自定義鍵盤

Simple

If you subclass Slidden.KeyboardViewController, you get a KeyboardView and nice autolayout constraints right out of the box. Subclassing is as easy as:

class KeyboardViewController: Slidden.KeyboardViewController {
    override func viewDidLoad() {
        super.viewDidLoad()

        // Add the keys we need to the keyboard
        setupKeys()
    }

Add keys to the keyboard.

func setupKeys() {
        let helloKey = KeyboardKeyView(type: .Character, keyCap: "Hello", outputText: "Hello")
        helloKey.textColor = UIColor.whiteColor()
        helloKey.color = UIColor.blueColor()
        self.keyboardView.addKey(helloKey, row: 0)

        let worldKey = KeyboardKeyView(type: .Character, keyCap: "World", outputText: "World")
        worldKey.textColor = UIColor.whiteColor()
        worldKey.color = UIColor.redColor()
        self.keyboardView.addKey(worldKey, row: 0)
}

Add images to your keys.

func setupKeys() {
    let shiftKey = KeyboardKeyView(type: .Shift, keyCap:"", outputText: "")
    let img = UIImage(named:"Shift")
    shiftKey.image = img
    shiftKey.imageView.contentMode = .Center
}

If you want your image to be the same color as your other keys' text, you can use shouldColorImage to have CoreGraphics redraw the image of your key with the uniform color.

func setupKeys() {
    let shiftKey = KeyboardKeyView(type: .Shift, keyCap:"", outputText: "")
    let img = UIImage(named:"Shift")

    shiftKey.image = img
    shiftKey.imageView.contentMode = .Center

    shiftKey.color = UIColor.blueColor()
    shiftKey.selectedColor = UIColor.darkerBlueColor()
    shiftKey.textColor = UIColor.whiteColor()
    shiftKey.shouldColorImage = true // Will redraw the Shift image to match `textColor`
}
