我已经在Xcode 6中集成了Facebook sdk（使用swift）。 在登录期间，我请求public_profile权限：
FBSession.openActiveSessionWithReadPermissions(["public_profile"], allowLoginUI: true, completionHandler: {
...
...
所以我要求用户提供信息：
FBRequestConnection.startForMeWithCompletionHandler { (connection, user, error) -> Void in
...
...
为什么用户对象不包含个人资料图片？如何获取用户个人资料图片？它不属于public_profile的一部分吗？
我收到以下信息：
2015-01-25 01:25:18.858 Test[767:23804] {
"first_name" = xxx;
gender = xxx;
id = xxxxxxxxx;
"last_name" = xxxxxx;
link = "https://www.facebook.com/app_scoped_user_id/xxxxxxxxx/";
locale = "xxxxx";
name = "xxxxxxx xxxxxxx";
timezone = 1;
"updated_time" = "2013-12-21T18:45:29+0000";
verified = 1;
}
P.S：xxx for privacy

个人资料图片实际上是公开的，您只需将用户ID添加到Facebook指定的个人资料图片网址，例如：
var userID = user["id"] as NSString
var facebookProfileUrl = "http://graph.facebook.com/\(userID)/picture?type=large"
这个特殊的网址应该返回＆＃34; large＆＃34;用户的个人资料图片的版本，但还有几个照片选项in the docs。

如果您想在与其他用户信息相同的请求中获取图片，则可以在一个图形请求中完成所有操作。它有点乱，但是它再次提出要求。
更多 Swift 3 方法
let request = FBSDKGraphRequest(graphPath: "me", parameters: ["fields": "id, name, first_name, last_name, email, picture.type(large)"])
let _ = request?.start(completionHandler: { (connection, result, error) in
guard let userInfo = result as? [String: Any] else { return } //handle the error
//The url is nested 3 layers deep into the result so it's pretty messy
if let imageURL = ((userInfo["picture"] as? [String: Any])?["data"] as? [String: Any])?["url"] as? String {
//Download image from imageURL
}
})
Swift 2
let request = FBSDKGraphRequest(graphPath: "me", parameters: ["fields": "id, name, first_name, last_name, email, picture.type(large)"])
request.startWithCompletionHandler({ (connection, result, error) in
let info = result as! NSDictionary
if let imageURL = info.valueForKey("picture")?.valueForKey("data")?.valueForKey("url") as? String {
//Download image from imageURL
}
})

使用Facebook SDK 4.0，您可以使用：
<强>夫特：
let pictureRequest = FBSDKGraphRequest(graphPath: "me/picture?type=large&redirect=false", parameters: nil)
pictureRequest.startWithCompletionHandler({
(connection, result, error: NSError!) -> Void in
if error == nil {
println("\(result)")
} else {
println("\(error)")
}
})
<强>目标-C：
FBSDKGraphRequest *request = [[FBSDKGraphRequest alloc]
initWithGraphPath:[NSString stringWithFormat:@"me/picture?type=large&redirect=false"]
parameters:nil
HTTPMethod:@"GET"];
[request startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection,
id result,
NSError *error) {
if (!error){
NSLog(@"result: %@",result);}

NSLog(@"result: %@",[error description]);
}}];

如果你想获得更大的图片，只需要替换＆＃34; type = large＆＃34; to width = XX＆amp; height = XX
但你可以得到的最大图片是原始图片
FBSDKGraphRequest *request = [[FBSDKGraphRequest alloc]
initWithGraphPath:@"me/picture?width=1080&height=1080&redirect=false"
parameters:nil
HTTPMethod:@"GET"];
[request startWithCompletionHandler:^(
FBSDKGraphRequestConnection *connection,
id result,
NSError *error) {
if (!error)
{
NSLog(@"result = %@",result);
NSDictionary *dictionary = (NSDictionary *)result;
NSDictionary *data = [dictionary objectForKey:@"data"];
NSString *photoUrl = (NSString *)[data objectForKey:@"url"];
}
else
{
NSLog(@"result = %@",[error description]); }
}];

let graphRequest = FBSDKGraphRequest(graphPath: "me", parameters: ["fields":"id, email, name, picture.width(480).height(480)"])
graphRequest?.start(completionHandler: { (connection, result, error) in
if error != nil {
print("Error",error!.localizedDescription)
}
else{
print(result!)
let field = result! as? [String:Any]
self.userNameLabel.text = field!["name"] as? String
if let imageURL = ((field!["picture"] as? [String: Any])?["data"] as? [String: Any])?["url"] as? String {
print(imageURL)
let url = URL(string: imageURL)
let data = NSData(contentsOf: url!)
let image = UIImage(data: data! as Data)
self.profileImageView.image = image
}
}
})

FBSDKProfile来获取大小的路径，这也是更模块化的而不是硬编码的（尽管我必须输入 graph.facebook.com 部分...）
let size = CGSize(width: 1080, height: 1080)
let path = FBSDKProfile.currentProfile().imagePathForPictureMode(.Normal, size: size)
let url = "https://graph.facebook.com/\(path)"
Alamofire.request(.GET, url, parameters: nil, encoding: ParameterEncoding.URL).response {
(request, response, data, error) -> Void in
if let imageData = data as? NSData,
let image = UIImage(data: imageData) {
self.buttonImage.setImage(image, forState: .Normal)
}
}
不知何故，我没有得到1080X1080图像，FB给了我一个1117X1117 ......：\

对于swift，这是获取照片的网址和特定尺寸的简单方法：
let params: [NSObject : AnyObject] = ["redirect": false, "height": 800, "width": 800, "type": "large"]
let pictureRequest = FBSDKGraphRequest(graphPath: "me/picture", parameters: params, HTTPMethod: "GET")
pictureRequest.startWithCompletionHandler({
(connection, result, error: NSError!) -> Void in
if error == nil {
print("\(result)")
let dictionary = result as? NSDictionary
let data = dictionary?.objectForKey("data")
let urlPic = (data?.objectForKey("url"))! as! String
print(urlPic)
} else {
print("\(error)")
}
})

谢谢@Lyndsey Scott。 对于Kingfisher，请将启用请求http添加到.plist文件中。
<key>NSAppTransportSecurity</key>

<key>NSAllowsArbitraryLoads</key>

<key>NSExceptionDomains</key>
<dict>
<key>http://graph.facebook.com</key>

然后将用户的图片资料设置为ImageView。
let facebookId = "xxxxxxx"
let facebookProfile: String = "http://graph.facebook.com/\(facebookId)/picture?type=large"
let url: URL = URL(string: facebookProfile)!
myImageView.kf.setImage(with: url)

对于Swift 5
首先添加所需的字段
let params = ["fields": "first_name, last_name, email, picture"]
创建图形请求
let graphRequest = GraphRequest(graphPath: "me", parameters: params, tokenString: token.tokenString, version: nil, httpMethod: .get)
graphRequest.start { (connection, result, error) in }
您将在json中获得结果
{
"first_name": "",
"last_name": "",
"picture": {
"data": {
"height": 50,
"is_silhouette": false,
"url": "",
"width": 50
}
},
"id": ""
}
根据json响应，捕获结果
if let error = error {
print("Facebook graph request error: \(error)")
} else {
print("Facebook graph request successful!")
guard let json = result as? NSDictionary else { return }
if let id = json["id"] as? String {
print("\(id)")
}
if let email = json["email"] as? String {
print("\(email)")
}
if let firstName = json["first_name"] as? String {
print("\(firstName)")
}
if let lastName = json["last_name"] as? String {
print("\(lastName)")
}
if let profilePicObj = json["picture"] as? [String:Any] {
if let profilePicData = profilePicObj["data"] as? [String:Any] {
print("\(profilePicData)")
if let profilePic = profilePicData["url"] as? String {
print("\(profilePic)")
}
}
}
}
}
您还可以通过在参数中发送所需的宽度来获取自定义宽度轮廓图片
let params = ["fields": "first_name, last_name, email, picture.width(480)"]
这就是整个代码的样子
if let token = AccessToken.current {
let params = ["fields": "first_name, last_name, email, picture.width(480)"]
let graphRequest = GraphRequest(graphPath: "me", parameters: params,
tokenString: token.tokenString, version: nil, httpMethod: .get)
graphRequest.start { (connection, result, error) in
if let error = error {
print("Facebook graph request error: \(error)")
} else {
print("Facebook graph request successful!")
guard let json = result as? NSDictionary else { return }
if let id = json["id"] as? String {
print("\(id)")
}
if let email = json["email"] as? String {
print("\(email)")
}
if let firstName = json["first_name"] as? String {
print("\(firstName)")
}
if let lastName = json["last_name"] as? String {
print("\(lastName)")
}
if let profilePicObj = json["picture"] as? [String:Any] {
if let profilePicData = profilePicObj["data"] as? [String:Any] {
print("\(profilePicData)")
if let profilePic = profilePicData["url"] as? String {
print("\(profilePic)")
}
}
}
}
}
}
