ios – Twitter屏幕名称在Parse中返回null

概述通过Twitter登录并尝试获取用户屏幕名称.屏幕名称每次都会生成一个空值.有任何想法吗？ PFUser *currentUser = [PFUser currentUser]; [PFTwitterUtils logInWithBlock:^(PFUser *user, NSError *error) { if (!user) { NSLog(@" 通过Twitter登录并尝试获取用户屏幕名称.屏幕名称每次都会生成一个空值.有任何想法吗？

PFUser *currentUser = [PFUser currentUser];    [PFTwitterUtils logInWithBlock:^(PFUser *user,NSError *error) {        if (!user) {            NSLog(@"Uh oh. The user cancelled the Twitter login.");            return;        } else if (user.isNew) {            twitterScreenname = [PFTwitterUtils twitter].screenname;            NSLog(@"%@",[PFTwitterUtils twitter].screenname);            Nsstring * requestString = [Nsstring stringWithFormat:@"https://API.twitter.com/1.1/users/show.Json?screen_name=%@",twitterScreenname ];                                        NSURL *verify = [NSURL URLWithString:requestString];                                        NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:verify];                                        [[PFTwitterUtils twitter] signRequest:request];                                        [NSURLConnection sendAsynchronousRequest:request queue:[NSOperationQueue mainQueue] completionHandler:^(NSURLResponse *response,NSData *data,NSError *connectionError) {                NSError *error;                NSDictionary* result = [NSJsONSerialization JsONObjectWithData:data options:NSJsONReadingallowFragments error:&error];                if (!error) {                   user.username =twitterScreenname;                   user[@"name"]= result[@"name"];                    user[@"profileDescription"] = result[@"description"];                  user[@"imageURL"] = [result[@"profile_image_url_https"] stringByReplacingOccurrencesOfString:@"_normal" withString:@"_bigger"];                    [user saveEventually];                }            }];          [self performSegueWithIDentifIEr: @"username" sender: self];        }

解决方法 我是这样做的：

[PFTwitterUtils logInWithBlock:^(BOol succeeded,NSError *error) {    if ([PFTwitterUtils islinkeDWithUser:[PFUser currentUser]]) {        NSURL *info = [NSURL URLWithString:@"https://API.twitter.com/1.1/account/settings.Json"];        NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:info];        [[PFTwitterUtils twitter] signRequest:request];        [NSURLConnection sendAsynchronousRequest:request queue:[NSOperationQueue mainQueue] completionHandler:^(NSURLResponse *response,NSError *connectionError) {            if (!!data) {                NSDictionary *dict = [NSJsONSerialization JsONObjectWithData:data options:NSJsONReadingMutableLeaves error:nil];                Nsstring *username = dict[@"screen_name"];                username = [username stringByReplacingOccurrencesOfString:@"Twitter:" withString:@""];                PFUser *user = [PFUser currentUser];                user[@"Twitter"] = username;                [user saveEventually];            } else {              //uh oh,no twitter response            }        }];    } else {        //uh oh,Failed login    }}];
