Question

我在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 webservice（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];

任何建议请。

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];
    }

要

- (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];

}

在iOS中未收到推送通知消息
