我写了以下代码：
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);
}
}];
但我最终总是得到一个Bad authentication错误。我觉得我错过了什么。有人可以检查我的代码吗？或者提供任何建议来检索Twitter用户个人资料图片？
谢谢
您是否考虑过为此使用第三方Twitter引擎？我已经使用FHSTwitterEngine取得了相当大的成功，它似乎正在积极开发中。
要提取个人资料图片，您可以执行以下操作：
[[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];
}
}];
这是我
过去尝试过的
[PFTwitterUtils logInWithBlock:^(PFUser *user, NSError *error) {
if (!user) {
NSLog(@"Uh oh. The user cancelled the Twitter login.");
[[NSNotificationCenter defaultCenter] postNotificationName:notificationUserLoginFailed
object:error];
return;
} else {
// TODO find a way to fetch details with Twitter..
NSString * requestString = [NSString stringWithFormat:@"https://api.twitter.com/1.1/users/show.json?screen_name=%@", user.username];
NSURL *verify = [NSURL URLWithString:requestString];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:verify];
[[PFTwitterUtils twitter] signRequest:request];
NSURLResponse *response = nil;
NSData *data = [NSURLConnection sendSynchronousRequest:request
returningResponse:&response
error:&error];
if ( error == nil){
NSDictionary* result = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingAllowFragments error:&error];
_NSLog(@"%@",result);
[user setObject:[result objectForKey:@"profile_image_url_https"]
forKey:@"picture"];
// does this thign help?
[user setUsername:[result objectForKey:@"screen_name"]];
NSString * names = [result objectForKey:@"name"];
NSMutableArray * array = [NSMutableArray arrayWithArray:[names componentsSeparatedByString:@" "]];
if ( array.count > 1){
[user setObject:[array lastObject]
forKey:@"last_name"];
[array removeLastObject];
[user setObject:[array componentsJoinedByString:@" " ]
forKey:@"first_name"];
}
[user saveInBackground];
}
[[NSNotificationCenter defaultCenter] postNotificationName:notificationUserDidLogin
object:nil];
return;
}
}];
请注意，您应该登录iOS设备才能使用此功能：

这是profile_image_url_https ;)
我们可以在不使用的情况下访问个人资料图片 推特 sdk .在iOS中使用社交框架，我们可以使用它。
我使用ACAccounts而不是Twitter IOS SDK MGTwitterEngine等。 将使用 iPhone 设置中提供的推特帐户。

试试这个，它是使用fabricSDK获取用户配置文件的最新消息
-(void)usersShow:(NSString *)userID
{
NSString *statusesShowEndpoint = @"https://api.twitter.com/1.1/users/show.json";
NSDictionary *params = @{@"user_id": userID};
NSError *clientError;
NSURLRequest *request = [[[Twitter sharedInstance] APIClient]
URLRequestWithMethod:@"GET"
URL:statusesShowEndpoint
parameters:params
error:&clientError];
if (request) {
[[[Twitter sharedInstance] APIClient]
sendTwitterRequest:request
completion:^(NSURLResponse *response,
NSData *data,
NSError *connectionError) {
if (data) {
// handle the response data e.g.
NSError *jsonError;
NSDictionary *json = [NSJSONSerialization
JSONObjectWithData:data
options:0
error:&jsonError];
NSLog(@"%@",[json description]);
}
else {
NSLog(@"Error code: %ld | Error description: %@", (long)[connectionError code], [connectionError localizedDescription]);
}
}];
}
else {
NSLog(@"Error: %@", clientError);
}
}
