问题:

I am developing a client of Youtube for iOS devices. I want to check if logged user did Like or dislike a specified video or not. But I can't find any support API (here)

When I load the feed of videos, I just found rating information below , No thing shows that logged user liked or disliked this video.

{
   "gd$rating":{
      "average":4.8963733,
      "max":5,
      "min":1,
      "numRaters":193,
      "rel":"http://schemas.google.com/g/2005#overall"
   },
   "yt$statistics":{
      "favoriteCount":"0",
      "viewCount":"111626"
   },
   "yt$rating":{
      "numDislikes":"5",
      "numLikes":"188"
   }
}

Did I make any mistake?

It can be done using YouTube Data API v3.

Currently, The official client youtube on android and iOS devices does not support this. User can't see that he/she liked or disliked a video. And, when I press "like" or "dislike" on iPad youtube app, the number of like on the youtube web does not change.

Unbelievable!
