【问题描述】：

我在我的 ios 应用中使用推送通知。

我无法从服务器获取推送通知消息。但是我可以在免费使用第三方服务器 APN Tester 时收到消息。

在我的应用程序中，我使用后端作为 .net 网络服务（即 asmx 文件）。以下是我用于推送通知的代码。

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions 


[[UIApplication sharedApplication] registerUserNotificationSettings:[UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeSound | UIUserNotificationTypeAlert | UIUserNotificationTypeBadge) categories:nil]];
[[UIApplication sharedApplication] registerForRemoteNotifications];

NSLog(@"didFinishLaunchingWithOptions");

return YES;

/-(void)application:(UIApplication*)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData*)deviceToken

NSLog(@"My token is: %@", deviceToken);

NSString *deviceTokenString = [NSString stringWithFormat:@"%@", deviceToken];

NSLog(@"didRegisterForRemoteNotificationsWithDeviceToken");

NSLog(@"My token is: %@", deviceTokenString);

UIAlertView *alert = [[UIAlertView alloc] initWithTitle:deviceTokenString
                                                message:@"devicetoken"
                                               delegate:self
                                      cancelButtonTitle:@"OK"
                                      otherButtonTitles:nil];
[alert show];

- (void)application:(UIApplication*)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData*)deviceToken

NSLog(@"My token is: %@", deviceToken);
_token_data =deviceToken;


NSString *title = [NSString stringWithFormat:@"%@",_token_data];
NSString *trimmedString = [title stringByReplacingOccurrencesOfString: @" " withString:@""];
trimmedString = [trimmedString stringByReplacingOccurrencesOfString: @"<" withString:@""];
trimmedString = [trimmedString stringByReplacingOccurrencesOfString: @">" withString:@""];

_tokenkey = [[NSString alloc] initWithData:deviceToken encoding:NSUTF8StringEncoding];

NSString *soapFormat = [NSString stringWithFormat:@"<?xml version=\"1.0\" encoding=\"utf-8\"?>\n"
                        "<soap:Envelope xmlns:xsi=\"http:/

                        "</soap:Envelope>\n"];

NSURL *locationOfWebService = [NSURL URLWithString:@"http://www.mywebsite.com/push.asmx"

wsDeviceToken.asmx"];

NSMutableURLRequest *theRequest = [[NSMutableURLRequest alloc]initWithURL:locationOfWebService];
NSString *msgLength = [NSString stringWithFormat:@"%lu",(unsigned long)[soapFormat length]];

任何建议请。

提前致谢。

【问题讨论】：

我没有看到您在哪里添加了委托方法 didReceiveRemoteNotification 和 didReceiveRemoteNotification:completionHandler ？

您使用的是苹果生产还是开发推送服务器？

谢谢，我们正在使用开发推送服务器...

你好，我已经添加了didReceiveRemoteNotification函数...但是我不知道在哪里以及如何添加didReceiveRemoteNotification:completionHandler这个函数..你能提供这个的源代码吗..

【参考方案1】：

jejai替换此方法

  - (void)application:(UIApplication *)application
    didReceiveRemoteNotification:(NSDictionary *)userInfo
    
         NSString *message = [[userInfo objectForKey:@"aps"]
                         objectForKey:@"alert"];
         UIAlertView *alert = [[UIAlertView alloc]
                          initWithTitle:@""
                          message:message
                          delegate:nil
                          cancelButtonTitle:@"OK"
                          otherButtonTitles:nil];
        [alert show];
    

到

- (void)application:(UIApplication *)application
didReceiveRemoteNotification:(NSDictionary *)userInfo
fetchCompletionHandler:(void (^)(UIBackgroundFetchResult))handler


     NSString *message = [[userInfo objectForKey:@"aps"]
                     objectForKey:@"alert"];
     UIAlertView *alert = [[UIAlertView alloc]
                      initWithTitle:@""
                      message:message
                      delegate:nil
                      cancelButtonTitle:@"OK"
                      otherButtonTitles:nil];
    [alert show];
