多屏助手API

1. 引入头文件

   #import <QXCClassSDK/QXCPlayBackSDKHeader.h>
   

2. 初始化SDK 并设置代理；更多代理API说明，请点击此处。

   [QXCPlayBackSDKHeader getInstance].delegate = self;
   

3. 唤起多屏助手

   • 通过扫码老师端的二维码获得相应数据

     {
         "command": "authorize",
         "data": {
             "name": "千学云",
             "token": "6e9c58dbfdc4b9765bb3|1|1594000755|31|2|4UHFO3effedavUZ9O|0"
         }
     }
     

   • 获取多屏UIViewController 并展示

     -(void)showMultiScreenAssistant{
         NSString *qrCodeResult = @"{\"command\": \"authorize\", \"data\": {\"name\": \"千学云\", \"token\": \"6e9c58dbfdc4b9765bb3|1|1594000755|31|2|4UHFO3effedavUZ9O|0\"}}";
         NSDictionary *resultDic = [NSJSONSerialization JSONObjectWithData:[qrCodeResult dataUsingEncoding:NSUTF8StringEncoding] options:NSJSONReadingMutableContainers error:nil];
         NSString *commandStr = [resultDic valueForKey:@"command"];
         if([commandStr isEqualToString:@"authorize"]){
             NSDictionary *dataDic = [resultDic valueForKey:@"data"];
             KMSAEnterParams *params = [[KMSAEnterParams alloc] init];
             params.pStr = [dataDic valueForKey:@"token"];
             params.userName = [dataDic valueForKey:@"name"];
             [self presentViewController:[QXCMultiScreenAssistantHeader getInstance].getMultiScreenAssistantVC animated:YES completion:nil];
             [[QXCMultiScreenAssistantHeader getInstance] enterMultiScreenAssistant:params];
         }
     }
     

4. 退出多屏助手，用户点击多屏助手返回按钮时，需要实现代理 closeMultiScreen方法，并调用清空接口

   -(void)closeMultiScreen{
       [[QXCMultiScreenAssistantHeader getInstance].getMultiScreenAssistantVC dismissViewControllerAnimated:YES completion:nil];
       [[QXCMultiScreenAssistantHeader getInstance] clearMultiScreenAssistant];
   }
