iphone - Twitter API(从 ID 到屏幕名称)

Question

我正在尝试将 Twitter 用户 ID(例如:77687121)转换为他们的用户名或屏幕名称(两者都可以)，但我遇到了一个问题...

我尝试按照这个 SO 问题的说明进行操作，但作为 Twitter api 的新手以及 Objective c 本身让我很难理解:http://stackoverflow.com/questions/10020672/php- twitter-api-get-users-lookup-grabbing-screen-name-from-id

我从该教程中编写了以下代码，我得到了这个...

- (void) turnFriendId: (NSString *)friID {
// Setup the URL, as you can see it's just Twitter's own API url scheme. In this case we want to receive it in JSON
NSLog(@"%@",friID);
NSURL *followingURL = [NSURL URLWithString:@"https://api.twitter.com/1/users/show.json"];
// Pass in the parameters (basically '.ids.json?screen_name=[screen_name]')
NSDictionary *parameters = [NSDictionary dictionaryWithObjectsAndKeys:friID, @"id_str", nil];
// Setup the request
TWRequest *twitterRequest = [[TWRequest alloc] initWithURL:followingURL
                                                parameters:parameters
                                             requestMethod:TWRequestMethodGET];
// This is important! Set the account for the request so we can do an authenticated request. Without this you cannot get the followers for private accounts and Twitter may also return an error if you're doing too many requests
[twitterRequest setAccount:theAccount];
// Perform the request for Twitter friends
[twitterRequest performRequestWithHandler:^(NSData *responseData, NSHTTPURLResponse *urlResponse, NSError *error) {
    if (error) {
        // deal with any errors - keep in mind, though you may receive a valid response that contains an error, so you may want to look at the response and ensure no 'error:' key is present in the dictionary
    }
    NSError *jsonError = nil;
    // Convert the response into a dictionary
    NSDictionary *twitterGrabbedUserInfo = [NSJSONSerialization JSONObjectWithData:responseData options:NSJSONWritingPrettyPrinted error:&jsonError];
    // Grab the Ids that Twitter returned and add them to the dictionary we created earlier
    NSLog(@"%@", [twitterGrabbedUserInfo objectForKey:@"name"]);
}];
}

这个方法有时会给我一个错误，有时它会中断并显示一些汇编代码...下面是错误... 以及第一个 NSLOG();在方法的开头...

terminate called throwing an exception(lldb)

这也是浏览每个单独的 Twitter ID(即使我有数千个)以获取每个用户的屏幕名称的好方法。我知道 Twitter 有 API 限制...

运行users/lookup调用

http://api.twitter.com/1/users/lookup.json?user_id=77687121,43662011,6253282

你可以用逗号分隔ID来调用一个电话。
