我已经为我的 iphone 目标和 apple watch 目标添加了一个组:
在我的 AppDelegate 中我有这段代码:
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
// Override point for customization after application launch.
let userDefaults = NSUserDefaults(suiteName: "group.tripicons")
userDefaults!.setObject("English", forKey: "languageOfCurrentCountry")
userDefaults!.setObject("English", forKey: "languageOfDevice")
userDefaults!.synchronize()
return true
}
但是，当它在我的方法中说它是 nil 时:
class LanguageManager: NSObject {
...
let userDefaults = NSUserDefaults(suiteName: "group.tripicons")
func watchTranslation(word: String) -> String {
print(userDefaults?.dictionaryRepresentation())
// BREAKS HERE
let language = userDefaults?.objectForKey("languageOfCurrentCountry") as! String // <---- BREAKS HERE
...
}
}
print 语句打印一个没有我正在寻找的键的对象:
Optional(["MSVLoggingMasterSwitchEnabledKey": 0, "AppleKeyboardsExpanded": 1, "AppleLanguages": (
en
), "AppleLanguagesDidMigrate": 2.1, "NSInterfaceStyle": macintosh, "NSLanguages": (
en
), "AppleKeyboards": (
"en_US@hw=US;sw=QWERTY",
"emoji@sw=Emoji",
"en_US@hw=US;sw=QWERTY"
)])
即使我在打开 Apple Watch 应用程序之前打开 iphone 应用程序也是如此。我错过了什么吗？

最佳答案
使用 NSUserDefaults 在 iPhone 和 Apple Watch 之间交换数据仅适用于 watchOS 1。
如果您正在为 watchOS 2 开发，您应该使用 WatchConnectivity 框架。请参阅 Apple 文档 here .
