iphone - 如何获取设备 token ？

Question

我将用户名、密码和 devicetoken 的值发布到 .net 网络服务。但它没有获得任何设备 token 值。我正在使用以下代码。

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions 
{ 
    [[UIApplication sharedApplication] setApplicationIconBadgeNumber:0]; 
    [[UIApplication sharedApplication] registerForRemoteNotificationTypes:UIRemoteNotificationTypeBadge|UIRemoteNotificationTypeAlert ]; 
}

- (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken 
{    
   NSLog(@"didRegisterForRemoteNotificationsWithDeviceToken: %@", deviceToken); 
   NSString *dt = [[deviceToken description] stringByTrimmingCharactersInSet:[NSCharacterSet characterSetWithCharactersInString:@"<>"]]; 
   dt = [dt stringByReplacingOccurrencesOfString:@" " withString:@""]; 
   self.DeviceToken=dt; 
   NSLog(@"~~~~devToken(dv)=%@",deviceToken);
}

- (void)application:(UIApplication*)application didFailToRegisterForRemoteNotificationsWithError:(NSError*)error
{      
    NSLog(@"Failed to get token, error: %@", error);
}

但在控制台中显示

Failed to get token, error: Error Domain=NSCocoaErrorDomain Code=3000 "no valid 'aps-environment' entitlement string found for application" UserInfo=0x1a0810 {NSLocalizedDescription=no valid 'aps-environment' entitlement string found for application

有什么想法吗？提前致谢!

您是否在临时文件中启用了推送通知？

通过the tutorial检查你是否做对了

首先尝试从您的 mac 向设备发送推送通知，如教程中所述。您需要在服务器端创建一个 pem 文件，您需要从 iOS 门户创建该文件 :)
