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。在解析了这个json文件并获取数据之后,如何使自定义键盘使用它并在键盘视图中显示,就像内置的表情符号键盘一样?现在,我按照应用程序扩展键盘:自定义键盘指南,这里只有一小部分信息。有关于如何在线创建自定义表情符号键盘的任何教程或指南吗?我正在尝试的当前代码如下:
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◕)",
"(¯﹃¯)"
]
}
]
}
