搜索API上的iOS Twitter实体

Question

I'm integrating some Twitter functions on my app. So basically what i want to do is to retrieve tweets based on some keywords (#hashtags) and from those extract if present pictures and present them to the user.

The problem is that on "GET Search" query such as "http://search.twitter.com/search.json?q=Twitter%20API&result_type=mixed&count=5" entities are not supported so I'm wondering how can I achieve my task.

I thought to get all the tweets with that query and then for each tweet do this call "GET statuses/show/:id" so i can get the entities for each tweet- get the link in the tweet text - and then make another call to a service where tweet pictures are stored and shared but it seems inefficient, it needs a lot of connection.

Answer 1

Just % escape the #. In a URL %23 is a #.

This query will look for tweets tagged #iphone.

http://search.twitter.com/search.json?q=%23iphone&result_type=mixed&count=5

To escape the string do this

NSString url = @"url with #hashtag"; NSString *escapedString = [url stringByReplacingPercentEscapesUsingEncoding:NSUTF8StringEncoding];

That will replace the # with %23.

Answer 2

当时Twitter Search API不支持实体，现在可以正常使用
