我遇到WatchConnectivity问题。
在我的应用程序中，我将带有数据的字典发送到AppleWatch。一切都在我的手表上。在那里，用户可以更改某些数据（我有一个艺术家列表，用户可以在其中检查或取消选中艺术家）。更改后，List应通过WatchConnectivity发送回我的iPhone。我使用函数updateApplicationContext。在我的AppDelegate类中，正确地读出了Dictionary，但之后我想将我的Artists设置为NSUserDefaults，但是如果我调试，我的NSUserDefaults中没有更改的值。
任何人都有一个想法如何将像Arrays等复杂对象发送回电话。
这是我的AppDelegate
class AppDelegate: UIResponder, UIApplicationDelegate, WCSessionDelegate {
var window: UIWindow?
func session(session: WCSession, didReceiveApplicationContext applicationContext: [String : AnyObject]){
if(applicationContext["myUserProfile"] != nil){
Utils().importMyUserProfileFromSession(applicationContext, getCompletionHandler: {(artists) -> Void in
Utils().saveArtists(artists, key: "profileArtistsFromWatch")
//in artists the Values are correct, so i save them here
//but if i want to read them out(load and save Function works!) the Array is empty...
let artists1 = Utils().loadArtists("profileArtistsFromWatch")
})
}
}
}
这是我的函数importMyUserProfileFromSession
func importMyUserProfileFromSession(applicationContext: [String: AnyObject], getCompletionHandler : (artists: [Artist]) -> Void){
let me = self.getProfileData()
var myArtists = me.artists
if(applicationContext["myUserProfile"] != nil){
let dictUser :[String: AnyObject] = applicationContext["myUserProfile"] as! [String: AnyObject]
// print(dictUser)
var artists : [Artist] = [Artist]()
if dictUser["artists"] != nil{
let dictArtists :[Int: AnyObject] = dictUser["artists"] as! [Int: AnyObject]
for j in 0..<dictArtists.count{
let dictArtist :[String: AnyObject] = dictArtists[j] as! [String: AnyObject]
var a : Artist = Artist()
if dictArtist["id"] != nil{
let indexOfArtist = self.getArtistById(dictArtist["id"] as! Int, artists: myArtists)
if(indexOfArtist != -1){
a.id = myArtists[indexOfArtist].id as! Int
print(a.id)
}
a.idInApp = dictArtist["id"] as! Int
}
if dictArtist["name"] != nil{
a.name = dictArtist["name"] as! String
}
if dictArtist["image"] != nil{
let imageData: NSData = dictArtist["image"] as! NSData
a.imageData = imageData
}
if dictArtist["active"] != nil{
let active: Bool = dictArtist["active"] as! Bool
a.display = active
}
artists.append(a)
}
getCompletionHandler(artists: artists)
}
}
}
