iOS 8 自定义键盘

问题描述

我正在尝试构建一个自定义键盘，它就像一个表情符号键盘，但键盘的数据来自一个 json 文件.解析这个json文件并获取数据后，如何让自定义键盘使用它并显示在键盘视图中，就像内置的表情符号键盘一样?现在，我遵循应用扩展键盘:自定义键盘指南，这里只有少量信息.有没有关于如何在线创建自定义表情符号键盘的教程或指南?我正在尝试的当前代码如下:

I am trying to build a custom keyboard, it's like a emoji keyboard, but the keyboard's data is from a json file. After parse this json file and get the data, how to make the custom keyboard use it and show in the keyboard view, like the emoji keyboard that built in? Right now, I follow App Extension Keyboard: Custom Keyboard guide, and there only small bits of information here. Is there any tutorial or guide about how to create a custom emoji keyboard online? The current codes I am trying are below:

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

        var error: NSError?
        let yanFile = NSBundle.mainBundle().pathForResource("yan", ofType: "json")
        let yanData = NSData(contentsOfFile: yanFile) as NSData
        let yanDict = NSJSONSerialization.JSONObjectWithData(yanData, options: NSJSONReadingOptions.MutableContainers, error: &error) as NSDictionary
        println("dict: (yanDict)") //print nothing in console

        // Perform custom UI setup here
        self.nextKeyboardButton = UIButton.buttonWithType(.System) as UIButton

        self.nextKeyboardButton.setTitle(NSLocalizedString("Next Keyboard", comment: "Title for 'Next Keyboard' button"), forState: .Normal)

    }
}

json如下:

{
    "list": 
    [
        {
            "tag": "laugh",
            "yan": 
            [
                "o(*≧▽≦)ツ┏━┓",
                "(/≥▽≤/)",
                "ヾ(o◕∀◕)ﾉ"
            ]
        },
        {
            "tag": "wanna",
            "yan": 
            [
                "✪ω✪",
                "╰(*°▽°*)╯",
                "≖‿≖✧",
                ">ㅂ<",
                "ˋ▽ˊ",
                "✪ε✪",
                "✪υ✪",
                "ヾ (o ° ω ° O ) ノ゙",
                "(｡◕ˇ∀ˇ◕）",
                "（¯﹃¯）"
            ]
        }
    ]
}

推荐答案

点击新建文件->查看即可构建xib文件

You can build a xib file by clicking new file -> view

1) 在 xib 文件中创建一个 uiview 320x216，您可以将任何您想要的控件拖放到其中

1) inside the xib file create a uiview 320x216 and you can drag'n'drop whatever controls you want into it

2) 然后您可以像这样将笔尖加载到键盘的 inputView 中:

2) then you can load the nib like this into your keyboard's inputView:

// Perform custom UI setup here
UIView *layout = [[[NSBundle mainBundle] loadNibNamed:@"keyboardXib" owner:self options:nil] objectAtIndex:0];
[self.inputView addSubview:layout];

3) 我认为如果你构建一个 JSON 到键盘 api 会很棒您将键盘映射的 JSON 发送到您的应用程序并且应用程序知道如何相应地安排 inputView 上的键

3) i think it's amazing if you build a JSON to keyboard api you send a JSON of the keyboard map to your app and the app knows how to arrange the keys on the inputView accordingly

如果您构建了这个项目，请告诉我们！

let us know if you build this project!

4) 您需要做的大部分工作是解析 JSON 并从 JSON uibuttons 中显示您想要的内容，并决定它们将哪些文本插入到文本字段中

4) Most of what you need to do is parse the JSON and display the content you want from the JSON uibuttons, and also decide what text they are inserting into the text field
