我希望获得带有特定主题标签的推文。我使用Twitter搜索URL。这是我的代码:
NSMutableString *urlString = [NSMutableString stringWithFormat:@"%s","http://search.twitter.com/search.json?q=%23zesdaagsegent"];
NSURL *url = [NSURL URLWithString:urlString];
NSData *data = [NSData dataWithContentsOfURL:url];
NSLog(@"%@", data);
NSError *error;
NSMutableArray *json = [NSJSONSerialization JSONObjectWithData:data options:kNilOptions error:&error];
NSLog(@"%@", json);
NSMutableArray *results =[NSMutableArray array];
for(NSDictionary *item in json)
{
[results addObject:[item objectForKey:@"results"]];
}
我的NSLog获取了我需要的输出:
2013-05-28 09:48:45.080 ZesdaagseGent [572:11303] { “completed_in”=“0.023”; “max_id”= 339031661368975360; “max_id_str”= 339031661368975360; page = 1; query =“%23zesdaagsegent”; “refresh_url”=“?since_id = 339031661368975360&amp; q =%23zesdaagsegent”; 结果=( { “created_at”=“星期一,2013年5月27日14:53:41 +0000”; “from_user”= SigfridMaenhout; “from_user_id”= 369194526; “from_user_id_str”= 369194526; “from_user_name”=“Sigfrid Maenhout”; geo =“”; id = 339031661368975360; “id_str”= 339031661368975360; “iso_language_code”= nl; metadata = { “result_type”=最近; }; source =“&lt; a href =”http://twitter.com/">web</a>“; text =“#zesdaagsegent Het is meen zonnige dag hier in Merelbeke。我们发表了关于他们的信息naar een beetje zonnestralen in het gezicht,toch?“; } ); “results_per_page”= 15; “since_id”= 0; “since_id_str”= 0; }
我需要带有对象的数组“results”。我的问题是我无法使用方法objectForKey在NSMutableArray中获得结果。
有没有人有想法?
答案 0 :(得分:2)
试试这个:
NSMutableArray *results = [NSMutableArray array];
NSDictionary *jsonResponse = [NSJSONSerialization JSONObjectWithData:data
options:kNilOptions
error:&error];
for (NSDictionary *result in jsonResponse[@"results"]) {
[results addObject:result];
}
你应该有一个NSArray results
包含每个匹配推文的X NSDictionary。
PS:[@“results”]是[NSDictionary objectForKey:@“results”]的现代Objective-C语法
