NSUbiquitousKeyValueStoreDidChangeExternallyNotification根本没有被调用？

var keyStore: NSUbiquitousKeyValueStore?

viewDidLoad{

NSNotificationCenter.defaultCenter().addObserver(self,
            selector: "ubiquitousKeyValueStoreDidChange:",
            name: NSUbiquitousKeyValueStoreDidChangeExternallyNotification,
            object: keyStore)



userDefinedLabelOne.text = keyStore?.stringForKey("userDefinedStringOne") <---this is changed

 }





func ubiquitousKeyValueStoreDidChange(notification: NSNotification) {

     println("Changed")  <---- Not called


    }

已在此处查看 iCloud Key-Value-Store Synchronization issues (NSUbiquitousKeyValueStoreDidChangeExternallyNotification not called)

在 iCloud 功能中选择键值存储

CloudKit 共享数据正常

数据已保存到云端，但不会调用更改通知

最佳答案

通过退出 iCloud 帐户并重新登录，一切都开始正常工作
