从Facebook iOS 7获取用户名和个人资料照片

我已经阅读了很多关于从Facebook获取信息的教程，但到目前为止我失败了。 我只想从Facebook获取用户名和个人资料照片。

- (IBAction)login:(id)sender { [FBSession openActiveSessionWithReadPermissions:@[@"email",@"user_location",@"user_birthday",@"user_hometown"] allowLoginUI:YES completionHandler:^(FBSession *session, FBSessionState state, NSError *error) { switch (state) { case FBSessionStateOpen: [[FBRequest requestForMe] startWithCompletionHandler:^(FBRequestConnection *connection, NSDictionary<FBGraphUser> *user, NSError *error) { if (error) { NSLog(@"error:%@",error); } else { // retrive user's details at here as shown below NSLog(@"FB user first name:%@",user.first_name); NSLog(@"FB user last name:%@",user.last_name); NSLog(@"FB user birthday:%@",user.birthday); NSLog(@"FB user location:%@",user.location); NSLog(@"FB user username:%@",user.username); NSLog(@"FB user gender:%@",[user objectForKey:@"gender"]); NSLog(@"email id:%@",[user objectForKey:@"email"]); NSLog(@"location:%@", [NSString stringWithFormat:@"Location: %@\n\n", user.location[@"name"]]); } }]; break; case FBSessionStateClosed: case FBSessionStateClosedLoginFailed: [FBSession.activeSession closeAndClearTokenInformation]; break; default: break; } } ]; } 

我用这个代码获取信息，但是我不能得到任何信息。 你能帮我吗？ 或者你更喜欢教程来阅读它？ 我已经阅读了developer.facebook.com上的教程。

感谢您的关注。

Answer 1

这是我find用户的个人资料图片最简单的方法。

 [[FBRequest requestForMe] startWithCompletionHandler:^(FBRequestConnection *connection, NSDictionary<FBGraphUser> *FBuser, NSError *error) { if (error) { // Handle error } else { NSString *userName = [FBuser name]; NSString *userImageURL = [NSString stringWithFormat:@"https://graph.facebook.com/%@/picture?type=large", [FBuser objectID]]; } }]; 

其他可以使用的查询参数是：

• types ：小，正常，大，方
• 宽度 ：<值>
• 高度 ：<值>
  • 使用宽度和高度来获得裁剪的方面填充图像

Answer 2

 if ([FBSDKAccessToken currentAccessToken]) { [[[FBSDKGraphRequest alloc] initWithGraphPath:@"me" parameters:@{ @"fields" : @"id,name,picture.width(100).height(100)"}]startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection, id result, NSError *error) { if (!error) { NSString *nameOfLoginUser = [result valueForKey:@"name"]; NSString *imageStringOfLoginUser = [[[result valueForKey:@"picture"] valueForKey:@"data"] valueForKey:@"url"]; NSURL *url = [[NSURL alloc] initWithURL: imageStringOfLoginUser]; [self.imageView setImageWithURL:url placeholderImage: nil]; } }]; } 

Answer 3

进行以下图表请求：

/me?fields=name,picture.width(720).height(720){url}

而且你会得到非常大的和酷的个人资料图片：

 { "id": "459237440909381", "name": "Victor Mishin", "picture": { "data": { "url": "https://fbcdn-profile-a.akamaihd.net/hprofile-ak-xpf1/t31.0-1/c628.148.1164.1164/s720x720/882111_142093815957080_669659725_o.jpg" } } } 

PS /me?fields=picture.type(large)不适合我。

Answer 4

你也可以得到如下的用户名和图片：

 [FBSession openActiveSessionWithReadPermissions:@[@"basic_info"] allowLoginUI:YES completionHandler: ^(FBSession *session, FBSessionState state, NSError *error) { if(!error && state == FBSessionStateOpen) { { [FBRequestConnection startWithGraphPath:@"me" parameters:[NSMutableDictionary dictionaryWithObjectsAndKeys:@"id,name,first_name,last_name,username,email,picture",@"fields",nil] HTTPMethod:@"GET" completionHandler:^(FBRequestConnection *connection, id result, NSError *error) { NSDictionary *userData = (NSDictionary *)result; NSLog(@"%@",[userData description]); }]; } } }]; Output: picture = { data = { "is_silhouette" = 0; url = "https://fbcdn-profile-a.akamaihd.net/hprofile-ak-frc1/t5.0-1/xxxxxxxxx.jpg"; }; }; username = xxxxxxxxx; 

您可以将参数保留为图片和用户名，并根据您的要求排除其他参数。 HTH。

Answer 5

这是Facebook SDK 4和Swift的代码：

 if FBSDKAccessToken.currentAccessToken() != nil { FBSDKGraphRequest(graphPath: "me", parameters: nil).startWithCompletionHandler({ (connection, result, error) -> Void in println("This logged in user: \(result)") if error == nil{ if let dict = result as? Dictionary<String, AnyObject>{ println("This is dictionary of user infor getting from facebook:") println(dict) } } }) } 

更新回答问题：

要下载公共个人资料图片，您需要从字典中获取Facebook ID：

 let facebookID:NSString = dict["id"] as AnyObject? as NSString 

然后使用facebook ID调用请求来为configuration文件图像绘制API：

 let pictureURL = "https://graph.facebook.com/\(fbUserId)/picture?type=large&return_ssl_resources=1" 

示例代码：

  let pictureURL = "https://graph.facebook.com/\(fbUserId)/picture?type=large&return_ssl_resources=1" // var URLRequest = NSURL(string: pictureURL) var URLRequestNeeded = NSURLRequest(URL: URLRequest!) println(pictureURL) NSURLConnection.sendAsynchronousRequest(URLRequestNeeded, queue: NSOperationQueue.mainQueue(), completionHandler: {(response: NSURLResponse!,data: NSData!, error: NSError!) -> Void in if error == nil { //data is the data of profile image you need. Just create UIImage from it } else { println("Error: \(error)") } }) 

Answer 6

实际上使用“ http://graph.facebook.com/ / picture？type = small”来获取用户的个人资料图片，甚至他们的朋友都很慢。

将FBProfilePictureView对象添加到视图和其profileID属性中的更好更快的方法是分配用户的Facebook标识。

例如：FBProfilePictureView * friendsPic;

friendsPic.profileID = @“1379925668972042”;
