从Objective C委托回调到Cordova插件
情况:我正在构建一个cordova插件来将现有的iOS库与Ionic连接.方法的基本映射已完成且正在运行，这意味着我可以通过Angular方法调用iOS方法并获取成功/错误回调.
Situation: I'm building a cordova plugin to connect an existing iOS library with Ionic. The base mapping of methods is done and working, means I can call the iOS methods via Angular methods and getting success/error callbacks.
问题:有一个登录方法被调用，然后调用了适当的委托方法(例如userDidLoginWithSuccess).从登录方法到cordova插件的回调很容易，但是我需要以某种方式从委托方法进行回调，以便让Ionic应用程序知道用户是否成功登录.
Problem: There's a login method which is called, and appropriate delegate methods (e.g. userDidLoginWithSuccess) are called afterwards. Callback from the login method to the cordova plugin is easy, but I need to somehow callback from the delegate method, in order to let the Ionic app know if the user was logged in successfully or not.
对此有何想法?谢谢.

在.h上创建一个属性callbackId，将用于存储插件的回调标识符
On your .h create a property callbackId that you will use to store the callback identifier of the plugin
@property (nonatomic, strong) NSString* callbackId;
然后，在您的插件方法上，将callbackId存储在您创建的属性上.
Then, on your plugin method, store the callbackId on the property you created.
self.callbackId = command.callbackId;
最后，在委托中，使用callbackId发送插件结果
and finally, on the delegate send the plugin result using the callbackId
CDVPluginResult* result = [CDVPluginResult resultWithStatus:CDVCommandStatus_OK messageAsString:@"string result"];
[self.commandDelegate sendPluginResult:result callbackId:self.callbackId];
