Question

我想找到app用户的twitter句柄的用户名，所以使用了这段代码：

ACAccountStore *accountStore = [[ACAccountStore alloc] init];
ACAccountType *accountType = [accountStore accountTypeWithAccountTypeIdentifier:ACAccountTypeIdentifierTwitter];
[accountStore requestAccessToAccountsWithType:accountType options:nil completion:^(BOOL granted, NSError *error) {
    if (granted) {
        NSArray *accounts = [accountStore accountsWithAccountType:accountType];

然后从返回的每个ACAccounts获取username属性。我发现如果你改变你的推特用户名，iOS仍然可以使用你的新用户名，但是保留你的旧用户名在其记录中，所以返回用户名属性实际上会返回你的旧用户名，然后你无法显示或用来匹配反对任何事情。

您可以通过以下方式获取用户ID：

NSDictionary *tempDict = [[NSMutableDictionary alloc] initWithDictionary:
                                                              [twitterAccount dictionaryWithValuesForKeys:[NSArray arrayWithObject:@"properties"]]];
NSString *tempUserID = [[tempDict objectForKey:@"properties"] objectForKey:@"user_id"];

我想知道如何使用该用户名来查找他们的实际用户名？

这里你去：twitterAccout.username应该返回实际的用户名...没有经过测试，但我确信它几乎可以肯定它会起作用！

ACAccountStore *accountStore = [[ACAccountStore alloc] init];
    ACAccountType *accountType = [accountStore accountTypeWithAccountTypeIdentifier:ACAccountTypeIdentifierTwitter];
[accountStore requestAccessToAccountsWithType:accountType options:nil completion:^(BOOL granted, NSError *error) {
    if(granted) {
        NSArray *accountsArray = [accountStore accountsWithAccountType:accountType];

        if ([accountsArray count] > 0) {
            ACAccount *twitterAccount = [accountsArray objectAtIndex:0];
            NSLog(@"%@",twitterAccount.username);
            NSLog(@"%@",twitterAccount.accountType);
        }
    }
}];

获取用户ID的Twitter用户名实际上比它应该更费力。 Facebook SDK使类似的过程变得更加容易（从未想过我曾经说过......）。

无论如何，要发布Twitter信息请求，您需要将您选择的帐户从帐户存储附加到TWRequest：

NSURL *url = [NSURL URLWithString:@"https://api.twitter.com/1.1/users/show.json"];
NSMutableDictionary *params = [NSMutableDictionary new];
[params setObject:tempUserID forKey:@"user_id"];
[params setObject:@"0" forKey:@"include_rts"]; // don't include retweets
[params setObject:@"1" forKey:@"trim_user"]; // trim the user information
[params setObject:@"1" forKey:@"count"]; // i don't even know what this does but it does something useful

TWRequest *request = [[TWRequest alloc] initWithURL:url parameters:params requestMethod:TWRequestMethodGET];
//  Attach an account to the request
[request setAccount:twitterAccount]; // this can be any Twitter account obtained from the Account store

[request performRequestWithHandler:^(NSData *responseData, NSHTTPURLResponse *urlResponse, NSError *error) {
    if (responseData) {
        NSDictionary *twitterData = [NSJSONSerialization JSONObjectWithData:responseData options:NSJSONReadingAllowFragments error:NULL];
        NSLog(@"received Twitter data: %@", twitterData);

        // to do something useful with this data:
        NSString *screen_name = [twitterData objectForKey:@"screen_name"]; // the screen name you were after

        dispatch_async(dispatch_get_main_queue(), ^{
        // update your UI in here
            twitterScreenNameLabel.text = screen_name;
        });

        // A handy bonus tip: twitter display picture
        NSString *profileImageUrl = [twitterData objectForKey:@"profile_image_url"];

        dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{

            NSData *imageData = [NSData dataWithContentsOfURL:[NSURL URLWithString:profileImageUrl]];
            UIImage *image = [UIImage imageWithData:imageData]; // the matching profile image

            dispatch_async(dispatch_get_main_queue(), ^{
                // assign it to an imageview in your UI here
                twitterProfileImageView.image = image;
            });
        });
    }else{
        NSLog(@"Error while downloading Twitter user data: %@", error);
    }
}];

请注意我如何在异步块中包装接口更新。这是为了确保界面不会冻结。我还提出了一个奖金提示，用于检索用户的个人资料图片，你是否如此倾向。

Answer 3

Thomas Verbeek的回答是正确的，但不赞成使用ios 7.

而不是：

TWRequest *request = [[TWRequest alloc] initWithURL:url parameters:params requestMethod:TWRequestMethodGET];

使用：

SLRequest *request = [SLRequest requestForServiceType:SLServiceTypeTwitter requestMethod:SLRequestMethodGET URL:url parameters:params];

还要确保导入Social.framework才能使用它。

使用帐户框架

获取Twitter帐户信息（用户名，全名等）

- (void)getTwitterAccountInformation
{
    ACAccountStore *accountStore = [[ACAccountStore alloc] init];
    ACAccountType *accountType = [accountStore accountTypeWithAccountTypeIdentifier:ACAccountTypeIdentifierTwitter];

    [accountStore requestAccessToAccountsWithType:accountType options:nil completion:^(BOOL granted, NSError *error) {
        if(granted) {
            NSArray *accountsArray = [accountStore accountsWithAccountType:accountType];

            if ([accountsArray count] > 0) {
                ACAccount *twitterAccount = [accountsArray objectAtIndex:0];
                NSLog(@"%@",twitterAccount.username);
                NSDictionary *tempDict = [[NSMutableDictionary alloc] initWithDictionary:
                                          [twitterAccount dictionaryWithValuesForKeys:[NSArray arrayWithObject:@"properties"]]];
                NSString *name = [[tempDict objectForKey:@"properties"] objectForKey:@"fullName"];
            }
        }
    }];
}
