如何在iOS的Twitter资料图片？

问题描述

我写了下面code：

NSURL *url = [NSURL URLWithString:@"http://api.twitter.com/1.1/users/show.json"];

NSDictionary *params = [NSDictionary dictionaryWithObjectsAndKeys:username, @"screen_name" ,[[controller.engine accessToken] secret]];

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

[request performRequestWithHandler:
 ^(NSData *responseData, NSHTTPURLResponse *urlResponse, NSError *error) {
     if (responseData) {
         NSDictionary *user = [NSJSONSerialization JSONObjectWithData:responseData
                                         options:NSJSONReadingAllowFragments
                                           error:NULL];

         NSString *profileImageUrl = [user objectForKey:@"profile_image_url"];

         NSLog(@"%@",profileImageUrl);
     }
 }];

但我总是最后得到一个坏认证错误。我觉得我失去了一些东西。会有人请检查我的code？或提供任何建议，以获取Twitter的用户配置文件照片？

But I always end up getting a Bad authentication error. I feel I'm missing something. Would anyone please check my code? Or provide any suggestions to retrieve twitter user profile pictures?

感谢

推荐答案

你有没有使用这种第三方Twitter的引擎考虑？我用具备相当的成功，似乎是正在积极发展。

Have you considered using a 3rd party Twitter engine for this? I've used FHSTwitterEngine with a fair amount of success, and it seems to be under active development.

要拉个人资料图片，你会做这样的事情：

To pull a profile picture you would do something like this:

[[FHSTwitterEngine sharedEngine]permanentlySetConsumerKey:@"<consumer_key>" andSecret:@"<consumer_secret>"];
[[FHSTwitterEngine sharedEngine]showOAuthLoginControllerFromViewController:self
withCompletion:^(BOOL success) {
    if (success) {
        UIImage *profileImg = [[FHSTwitterEngine sharedEngine] getProfileImageForUsername:@"<username>" andSize:size];
    }
}];
