Voip推送通知在带有iOS 10.3的iPhone 7上崩溃

Question

我正在处理voip通知实施。 我的版本在iOS 11的设备iPhone 6上运行良好。 但它在iOS 7与iOS 10.3.3版本上崩溃，并出现以下错误：

pushregistry：didreceiveincomingpushwithpayload：fortype：]：无法识别的选择器发送到实例

如果有任何身体出现此类问题，请帮助我。

Answer 1

从iOS11弃用委托方法。 因此，请根据您的操作系统版本

执行以下代表

@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
}

Answer 2

您已使用如下所示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;

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;

如果您需要更多帮助，请告诉我。
