我正在尋找通過multipeer連接框架發送和接收NSManagedObject。Multipeer Connectivity發送和接收NSManagedObject
class MyObject: NSManagedObject {
@NSManaged var name: String
@NSManaged var children: NSSet
}
我已經成功地發送字符串和詞典，但我需要發送一個NSManagedObject與NSSet中。這可能嗎？
這是我已經試過：
let data = NSKeyedArchiver.archivedDataWithRootObject(nsmanagedobject)
if session.connectedPeers.count > 0 {
var error: NSError?
if !session.sendData(data,toPeers: session.connectedPeers, withMode: .Reliable, error: &error){
println("SEND ERROR:")
println(error)
}
} else {
println("NO PEERS CONNECTED!")
}
func session(session: MCSession!, didReceiveData data: NSData!, fromPeer peerID: MCPeerID!) {
NSLog("%@", "didReceiveData: \(data.length) bytes")
let nsmanagedobject = NSKeyedUnarchiver.unarchiveObjectWithData(data) as! MyObject
}
