我找不到任何有关在swift和xcode 6中获取用户位置信息的信息
I couldn't find any info about getting user's location info in swift and xcode 6

推荐答案
也许您可以向我们提供更多信息,例如您正在使用哪个Facebook SDK,FBSDKGraphRequest
必须返回什么参数user
.请注意,当您发送用户配置文件的图形请求时,没有关于国家的特定信息,即用户节点中的location
字段.它将返回子字段:id
和name
,其中名称为
Perhaps you could supply us with a little more information, e.g. which Facebook SDK you are using and what parameters FBSDKGraphRequest
has to return user
. Note that there is no specific information about country, the location
field in the user node when your send a graph request for the user profile. It will return the subfields: id
and name
, where name is
使用最新的Facebook iOS SDK 4.0,您可以执行以下操作:
With the latest Facebook iOS SDK 4.0 you can do something like:
override func viewDidLoad() {
super.viewDidLoad()
self.loginView.delegate = self
if FBSDKAccessToken.currentAccessToken() != nil {
fetchUserData()
} else {
loginView.readPermissions = ["public_profile", "email", "user_friends"]
}
}
func fetchUserData() {
let graphRequest: FBSDKGraphRequest = FBSDKGraphRequest(graphPath: "me", parameters: nil)
graphRequest.startWithCompletionHandler({ (connection, result, error) -> Void in
if error != nil {
// Process error
println("Error: \(error)")
} else {
let location: NSDictionary! = result.valueForKey("location") as NSDictionary
let city: NSString = location.valueForKey("name") as NSString
}
})
}
