Voip推送通知在使用iOS 10.3的iPhone 7上崩溃

我正在研究voip通知的实现。 我的版本在配备iOS 11.3的iPhone 6设备上运行良好。 但它在iOS 10.3.3版本的iPhone 7上崩溃，错误如下：

pushregistry:didreceiveincomingpushwithpayload:fortype:：发送到实例的选择器无法识别

如果有任何主体面临此类问题，请帮助我。

您已经使用下面的完成处理程序实现了委托方法

- (void)pushRegistry:(PKPushRegistry *)registry didReceiveIncomingPushWithPayload:(PKPushPayload *)payload 
         forType:(PKPushType)type withCompletionHandler:(void (^)(void))completion;

- (void)pushRegistry:(PKPushRegistry *)registry didReceiveIncomingPushWithPayload:(PKPushPayload *)payload 
         forType:(PKPushType)type;

请在没有完成处理程序的情况下实现相同的委托方法，如下所示

- (void)pushRegistry:(PKPushRegistry *)registry didReceiveIncomingPushWithPayload:(PKPushPayload *)payload 
         forType:(PKPushType)type withCompletionHandler:(void (^)(void))completion;

- (void)pushRegistry:(PKPushRegistry *)registry didReceiveIncomingPushWithPayload:(PKPushPayload *)payload 
         forType:(PKPushType)type;

如果需要更多帮助，请务必告诉我。

iOS11不推荐使用委托方法。 因此，请根据您的操作系统版本完成以下任务

@available(iOS, introduced: 8.0, deprecated: 11.0)
public func pushRegistry(_ registry: PKPushRegistry, didReceiveIncomingPushWith payload: PKPushPayload, forType type: PKPushType) {
//do the necessary operations
}

@available(iOS 11.0, *)
public func pushRegistry(_ registry: PKPushRegistry, didReceiveIncomingPushWith payload: PKPushPayload, for type: PKPushType, completion: @escaping () -> Swift.Void) {
//do the necessary operations
}

---

请为“didreceiveincomingpushwithpayload”功能以及您收到的带有通知的有效负载数据添加代码。根据这一点，您正在尝试获取一些不存在的键。我认为您必须实现pushRegistry:didReceiveIncomingPushWithPayload:forType:withCompletionHandler:以及下面的ios 11Hi。现在我正在使用func pushRegistry（uRegistry:PKPushRegistry，didReceiveIncomingPushWith payload:PKPushPayload，for type:PKPushType，completion:@escaping（）->Void）{}您的意思是说我还需要实现以下委托：@nonobjc func pushRegistry（registry:PKPushRegistry！，didReceiveIncomingPushWith payload:PKPushPayload！，forType:String！）{}是的，添加没有完成处理程序的完全相同的委托。就像这样，pushRegistry（uRegistry:PKPushRegistry，didReceiveIncomingPushWith payload:PKPushPayload，for type:PKPushType（）->Void）{}
