UIAlert與iOS 7的AddSubview替換

當前的代碼工作完美的iOS 7之前，在iOS 7沒有字段輸入用戶的名稱，從掃描這些論壇我發現在iOS7上更改與addsubview函數有關的東西，這裏是當前的代碼;UIAlert與iOS 7的AddSubview替換

任何人都可以協助將這個與iOS7（最好不破的iOS 6的環節寧願保持應用程序既OS版本兼容）工作

- (void) createScoreInput { 

    changePlayerAlert = [UIAlertView new]; 
    changePlayerAlert.title = @"Enter your name"; 
    changePlayerAlert.message = @"\n\n"; 
    changePlayerAlert.delegate = self; 
    [changePlayerAlert addButtonWithTitle:@"Save"]; 
    [changePlayerAlert addButtonWithTitle:@"Cancel"]; 

    CGRect frame = changePlayerAlert.frame; 
    frame.origin.y -= 100.0f; 
    changePlayerAlert.frame = frame; 

    changePlayerTextField = [[UITextField alloc] initWithFrame:CGRectMake(20, 50, 245, 27)]; 

    changePlayerTextField.borderStyle = UITextBorderStyleRoundedRect; 
    [changePlayerAlert addSubview:changePlayerTextField]; 
    changePlayerTextField.keyboardType = UIKeyboardTypeNamePhonePad; 
    changePlayerTextField.returnKeyType = UIReturnKeyDone; 
    changePlayerTextField.autocorrectionType = UITextAutocorrectionTypeNo; 
    changePlayerTextField.autocapitalizationType = UITextAutocapitalizationTypeNone; 
    changePlayerTextField.delegate = self; 


}

需要輸入由於有文檔中的iOS 7蘋果公司指出，你不能改變[中'UIAlertView']（https://developer.apple.com/library/ios/documentation/uikit/reference/UIAlertView_Class/UIAlertView/UIAlertView.html）：'視圖層次結構是類是私人的，不能被修改。' – rckoenes

@rckoenes我也相信這也是iOS 6和iOS 5的情況，但蘋果現在實際上對它更加嚴格。 – Popeye
