NW推杆推PayLoad - iOS斯威夫特

Question

我收到错误了

'can't invoke the push pay load with the argument list of types (NSString , token : NSString ,identifier:int32 error :inout NSError?)'

对于下一行

    var error:NSError? = nil
    var Pusher:NWPusher = NWPusher.connectWithPKCS12Data(PKS12,password:"as",error: &error)
    println(Pusher)
    var payLoad:NSString = "{\"aps\":{\"alert\":\"Testing From Swift App\"}}";
    var token:NSString = "token string here"
    var PayLoaderror:NSErrorPointer? = nil
    var pushed:Bool = Pusher.pushPayload(payLoad, token: token, identifier:rand() ,error: &error)

Answer 1

var error:NSError? = nil 
var Pusher:NWPusher = NWPusher.connectWithPKCS12Data(PKS12,password:"as",error: &error) 
println(Pusher) 
var payLoad:NSString = "{\"aps\":{\"alert\":\"Testing From Swift App\"}}"
var token:NSString = "Token here" 

// here is my new line of code
//
// also make certain Int32 is capitalized; case sensitivity matters!
let identifier = rand() as Int32

let pushed = Pusher.pushPayload(payLoad, token: token, identifier: identifier ,error: &error)
