iOS要怎么获取devtoken 现在能在log中看到 但是下面代码获取不到

[nianshaofanghua]

/// get DeviceToken [DeviceToken]
static Future<String?> deviceToken() async {
Map<String, dynamic> args = {};
return _methodChannel.invokeMethod('deviceToken', args);
}

我是修改了iOS代码，增加didRegisterForRemoteNotificationsWithDeviceToken方法，在这个方法中获取deviceToken，将值写入userdefault。

放AppDelegate.swift里

override func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
      let deviceTokenStr = [UInt8](deviceToken).map{String(format: "%02x", $0)}.joined()
      NSLog("deviceToken：-------->  " + deviceTokenStr)
      UserDefaults.standard.set(deviceTokenStr, forKey: "push_device_token")
   }
