Swift 中的本地通知在 iOS 7 崩溃

Question

我正在尝试将本地通知添加到我的游戏中。该代码适用于 iOS 8，但是当我尝试在 iOS 7 上对其进行测试时，它就崩溃了。

这是注册通知的代码（在 App Delegate 中）

let notificationType = UIUserNotificationType.Alert | UIUserNotificationType.Badge | UIUserNotificationType.Sound
let settings = UIUserNotificationSettings(forTypes: notificationType, categories: nil)
application.registerUserNotificationSettings(settings)

这是我设置通知的代码

UIApplication.sharedApplication().cancelAllLocalNotifications()

notification.fireDate = NSDate(timeIntervalSinceNow: 3600)
notification.alertBody = "Come back and play"
notification.alertAction = "to play"
notification.applicationIconBadgeNumber = 1

UIApplication.sharedApplication().scheduleLocalNotification(notification)

注册通知时崩溃。

Answer 1

In iOS 7 registerUserNotificationSettings 是无法识别的选择器，会崩溃。您需要查看它是否响应该选择器，以及它是否不调用 registerForRemoteNotificationTypes: 相反。
