ios - 应用程序连接错误 : AppConnect cannot be instantiated directly

Question

我正在尝试使用 swift 1.2 中的 AppConnect SDK 访问 MDM，但出现以下错误:

[AppConnect:Error] AppConnect cannot be instantiated directly. Instead, call +initWithDelegate: and then +sharedInstance.

代码片段:

 import UIKit

    @UIApplicationMain
    class AppDelegate: UIResponder, UIApplicationDelegate, AppConnectDelegate {

        var window: UIWindow?        
        var appct = AppConnect()

        func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
            // Override point for customization after application launch.   

            // Initialize the AppConnect library
            AppConnect.initWithDelegate(self)
            self.appct = AppConnect.sharedInstance()
            self.appct.startWithLaunchOptions(launchOptions)

            return true
        } 
}

应用程序在访问 MobileIron 后端配置文件的 key 时崩溃。

还有其他实现方式吗？

Answer 1

您正在初始化没有委托(delegate)的 AppConnect

改变

var appct = AppConnect();

到

var appct : AppConnect!;
