Iphone 如何在didFinishLaunchingWithOptions中获取设备令牌

我正在我的第一个

视图控制器中调用设备令牌。我无法得到结果，因为设备令牌为空。下面是我在
appdelegate
中的代码：

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

    return YES;
}
- (void)application:(UIApplication *)app didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken
{
    token = [[deviceToken description] stringByTrimmingCharactersInSet:      [NSCharacterSet characterSetWithCharactersInString:@"<>"]];
    token = [token stringByReplacingOccurrencesOfString:@" " withString:@""];
    NSLog(@"Device Token ---%@", token);
    [[NSUserDefaults standardUserDefaults] setObject:token forKey:@"DeviceToken"];
    [[NSUserDefaults standardUserDefaults] synchronize];
}

令牌为空。
试试这个，我的朋友

    - (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)devToken {
              #if !TARGET_IPHONE_SIMULATOR

// Prepare the Device Token for Registration (remove spaces and < >)
token = [[[[devToken description]
                        stringByReplacingOccurrencesOfString:@"<"withString:@""]
                       stringByReplacingOccurrencesOfString:@">" withString:@""]
                      stringByReplacingOccurrencesOfString: @" " withString: @""];
NSLog(@"%@",token);
[[NSUserDefaults standardUserDefaults] setObject:token forKey:@"deviceToken"];
[[NSUserDefaults standardUserDefaults] synchronize];
        #endif
}
/**
  * Failed to Register for Remote Notifications
 */
  - (void)application:(UIApplication *)application didFailToRegisterForRemoteNotificationsWithError:(NSError *)error {
    #if !TARGET_IPHONE_SIMULATOR

   NSLog(@"Error in registration. Error: %@", error);
  #endif
  }

-（void）应用程序：（UIApplication*）应用程序DIDregisterForRemotionTificationswithDeviceToken:（NSData*）devToken{
#如果！目标\u IPHONE\u模拟器
//准备要注册的设备令牌（删除空格和<>）
令牌=[[[devToken description]
StringByReplacingOfString:@“with String:@”]
StringByReplacingOfString:@“和字符串：@]”发生；
NSLog（@“%@”，令牌）；
[[NSUserDefaults standardUserDefaults]setObject:token forKey:@“deviceToken”]；
[[NSUserDefaults standardUserDefaults]同步]；
#恩迪夫
}
/**
*无法注册远程通知
*/
-（无效）应用程序：（UIApplication*）应用程序未能注册远程通知，错误为：（N错误*）错误{
#如果！目标\u IPHONE\u模拟器
NSLog（@“注册错误。错误：%@”，错误）；
#恩迪夫
}

快乐编码！！！！

添加两种方法didRegister和didFailedToRegister，并确认您在didRegister或didFailedToRegister中收到呼叫

-(void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken
{
    NSLog(@"Device Token=> %@",deviceToken);

    //Parse your device toke

}

-(void)application:(UIApplication *)application didFailToRegisterForRemoteNotificationsWithError:(NSError *)error
{
    NSLog(@"Error in registration. Error: %@", error.description);
}

并确保您成功获取设备令牌。或者您未能注册或删除…

您可以尝试此项

- (void)application:(UIApplication*)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData*) deviceToken {
    NSString *pushToken = [deviceToken description];
    pushToken = [pushToken stringByTrimmingCharactersInSet:[NSCharacterSet characterSetWithCharactersInString:@"<>"]];
    [[NSUserDefaults standardUserDefaults] setObject:pushToken forKey:@"device_token_data"];
    [[NSUserDefaults standardUserDefaults] synchronize];
}

-（void）应用程序：（UIApplication*）应用程序DIDregisterforRemotionTificationswithDeviceToken:（NSData*）deviceToken{
NSString*pushToken=[deviceToken描述]；
pushToken=[pushToken stringByTrimmingCharactersInSet:[NSCharacterSet characterSetWithCharactersInString:@”“]；
[[NSUserDefaults standardUserDefaults]setObject:pushToken-forKey:@“设备\令牌\数据”]；
[[NSUserDefaults standardUserDefaults]同步]；
}
你可以试试这个

- (void)application:(UIApplication*)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData*) deviceToken {
    NSString *pushToken = [deviceToken description];
    pushToken = [pushToken stringByTrimmingCharactersInSet:[NSCharacterSet characterSetWithCharactersInString:@"<>"]];
    [[NSUserDefaults standardUserDefaults] setObject:pushToken forKey:@"device_token_data"];
    [[NSUserDefaults standardUserDefaults] synchronize];
}

-（void）应用程序：（UIApplication*）应用程序DIDregisterforRemotionTificationswithDeviceToken:（NSData*）deviceToken{
NSString*pushToken=[deviceToken描述]；
pushToken=[pushToken stringByTrimmingCharactersInSet:[NSCharacterSet characterSetWithCharactersInString:@”“]；
[[NSUserDefaults standardUserDefaults]setObject:pushToken-forKey:@“设备\令牌\数据”]；
[[NSUserDefaults standardUserDefaults]同步]；
}
可能会对您有所帮助

首先在中注册通知，然后您将在

    self.strdeviceToken=[self.strdeviceToken stringByAddingPercentEscapesUsingEncoding:NSASCIIStringEncoding];

您应该检查您的资源调配配置文件。此外，应用程序还应该配置为在开发者门户上发送推送通知。
为此，请执行以下步骤

在开发人员门户上为应用程序标识符启用推送通知
重新生成配置文件
下载并安装新的资源调配配置文件
构建并运行。
它会起作用的
