无法将Pass添加到Apple Wallet

Question

我正在用Apple Wallet做一些测试。我有一个通行证，我想在用户点击一个按钮时添加到他们的钱包中。下面是我的代码:

        let filePath = Bundle.main.path(forResource: "DealsPasses", ofType: "pkpass")!
        let passData = try? Data(contentsOf: URL.init(fileURLWithPath: filePath), options: .alwaysMapped)
        let pass = PKPass(data: passData!, error: nil)
        let passVC = PKAddPassesViewController(pass: pass)
        navigationController?.pushViewController(passVC, animated: true)

然而

;当用户点击按钮时，

AX Exchange error: Error Domain=Accessibility Code=0 "Remote service does not respond to _accessibilityMachPort" UserInfo={NSLocalizedDescription=Remote service does not respond to _accessibilityMachPort}

以~200/min的速率发送到控制台，并且没有PKAddPassesViewController呈现(或者如果有，它只是一个普通的白色视图)

在iPhone SE (device)上运行xCode 8

(边注:拖拽dealspass。Pkpass进入模拟器工作正常)

Please use the following code in swift 4.

请从此链接下载示例通行证，并将这些通行证保存在应用程序沙盒中。

import PassKit
//Function to open wallet view in your app. 
func loadWalletView() {
        if !PKPassLibrary.isPassLibraryAvailable() {
            let alert = UIAlertController(title: "Error", message: "PassKit not available", preferredStyle: .alert)
            alert.addAction(UIAlertAction(title: "OK", style: .default, handler: { action in
                switch action.style{
                case .default:
                    print("default")
                case .cancel:
                    print("cancel")
                case .destructive:
                    print("destructive")
                @unknown default:
                    break
                }}))
            self.present(alert, animated: true, completion: nil)
        }
        let resourcePath : String? = Bundle.main.resourcePath
        do {
            let passFiles : NSArray = try FileManager.default.contentsOfDirectory(atPath: resourcePath!) as NSArray
            for  passFile in passFiles {
                let passFileString = passFile as! String
                if passFileString.hasSuffix(".pkpass") {
                    openPassWithName(passName: passFileString)
                }
            }
        }catch {
            print(error.localizedDescription)
        }
    }
func openPassWithName(passName : String) {
        print(passName)
        let passFile = Bundle.main.resourcePath?.appending("/(passName)")
        let passData = NSData(contentsOfFile: passFile!)
        do {
            let newpass = try PKPass.init(data: passData! as Data)
            let addController =  PKAddPassesViewController(pass: newpass)
            addController?.delegate = self
            self.present(addController!, animated: true)
        } catch {
            let alert = UIAlertController(title: "Error", message: "PassKit not available", preferredStyle: .alert)
            alert.addAction(UIAlertAction(title: "OK", style: .default, handler: { action in
                switch action.style{
                case .default:
                    print("default")
                case .cancel:
                    print("cancel")
                case .destructive:
                    print("destructive")
                @unknown default:
                    break
                }}))
            self.present(alert, animated: true, completion: nil)
            print(error)
        }
    }

问题原来是与将PKAddPassesViewController推送到导航控制器的堆栈有关。

取代navigationController?.pushViewController(passVC, animated: true)用present(passVC, animated: true, completion: nil)解决了这个问题!
