更改密碼PFuser

你如何讓用戶更改密碼，郵件，用戶名等任何想法？到目前爲止，我有這個代碼，你可以在下面看到。我的問題是舊數據不顯示，我不能更新它。我會喜歡一些幫助！ :)非常感謝更改密碼PFuser

不要查詢用戶對象。你已經有一個在[PFUser currentUser];你可以從這個對象直接字段：

PFUser curUser = [PFUser currentUser]; 
_usernameField.text = [curUser valueForKey:@"username"];

或者乾脆

_usernameField.text = curUser[@"username"];

你updateSave方法是正確的，但我不知道爲什麼你使用「NEWMAIL」，「新密碼「等我猜你想在這裏使用」密碼「，」用戶名「等，除非你想設置一個名爲」新名稱「的用戶配置文件...

謝謝你這麼吃@handsomeguy！我將它改爲： 'PFUser * curUser = [PFUser currentUser]; _usernameField.text = [curUser valueForKey：@「username」]; _passwordField.text = [curUser valueForKey：@「password」]; _mailField.text = [curUser valueForKey：@「email」]; _usernameField.text = curUser [@「username」]; _passwordField.text = curUser [@「password」]; _mailField.text = curUser [@「email」]; ' 我也拿走了newpassword等它更好地工作，但我得到這個錯誤：錯誤：用戶可能沒有密碼字段（代碼：105，版本：1.2.18） – TheNiceOne

我想你沒有從這個上面的代碼，但從你更新密碼的代碼？沒有閱讀它？ – Moonwalkr

你的意思是這個代碼？（IBAction）updateSave：（id）sender //使用配方信息創建PFObject PFUser * profile = [PFUser currentUser]; [profile setObject：_usernameField.text forKey：@「name」]; [profile setObject：_passwordField.text forKey：@「password」]; [profile setObject：_mailField.text forKey：@「email」];' ----- – TheNiceOne

你的代碼看起來不錯。只有這應該工作：

[PFUser currentUser].password = someTextField.text;

但有些時候XCode緩存數據。清理你的項目，然後嘗試再次構建。

謝謝我編輯我的問題與完整的代碼，所以你可能會看到，如果有什麼我可以做.. – TheNiceOne

認爲你有解決方案。祝你好運。 :) – Rashad

是的！謝謝你 – TheNiceOne
