- @IBAction func BtnFaceBookLogin(_ sender: Any)
{
let fbLoginManager : FBSDKLoginManager = FBSDKLoginManager()
fbLoginManager.logOut()
fbLoginManager.logIn(withReadPermissions: ["public_profile", "email"], from: self) { (result, error) -> Void in
if (error == nil){
let fbloginresult : FBSDKLoginManagerLoginResult = result!
if(fbloginresult.grantedPermissions.contains("email"))
{
self.getFBUserData()
}
}
}
}
func getFBUserData()
{
if((FBSDKAccessToken.current()) != nil)
{
FBSDKGraphRequest(graphPath: "me", parameters: ["fields": "id, name, first_name, last_name, picture.type(large),
email"]).start(completionHandler: { (connection, result, error) ->
Void in
if (error == nil)
{
print(result!)
let socialID1:[String:AnyObject] = result as! [String : AnyObject]
let socialID = socialID1["id"] as! String
print(socialID)
}
else
{
print("Not Dismiss");
}
})
}
}
我试过这段代码但没有得到任何回应，出现错误:
unexpectedly found nil while unwrapping an Optional value
我没有获得 FBSDKtoken。
最佳答案
let loginManager = FBSDKLoginManager()
loginManager.logIn(withReadPermissions: ["user_about_me", "email" , "user_birthday","user_hometown"], from: self) { (loginResult, error) in
if error != nil
{
}
else
{
if loginResult?.grantedPermissions == nil
{
return
}
if (loginResult?.grantedPermissions.contains("email"))!
{
if (loginResult?.grantedPermissions.contains("user_birthday"))!
{
self.getFBUserData()
}
}
}}
}
func getFBUserData()
{
FBSDKGraphRequest.init(graphPath: "me?fields=id,name,email,first_name,last_name,cover,picture.type(large),gender,birthday,hometown", parameters: nil).start(completionHandler: { (connection , result , error ) in
if(error == nil){
DispatchQueue.main.async {
let dictionary = result as! NSDictionary
print(dictionary)
print("Name : \(dictionary.value(forKey: "name")!)")
print("FB ID : \(dictionary.value(forKey: "id")!)")
}
}else{
self.showalert(strMessage: "Somthig Went Wrong..!")
}
})
}
在 Swift-3 中试试这个
