iTunes拒绝我的应用程序，因此我必须对其进行修改。我做了它，现在我无法启动模拟器上的应用：构建失败：未找到符号

这里是结尾：

也许它要求我不包含一个库（我停处理有关，因为很多库）...
编辑：该错误是由新的代码来我已经改变，因为如果在商店应用程序的拒绝
这是我的代码（运行，但通过ItunesConnect拒绝）
UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Login et mot de passe" message:@"" delegate:self cancelButtonTitle:@"Annuler" otherButtonTitles:@"Sauvegarder", nil];
[alertView addTextFieldWithValue:@"" label:@"Login"];
[alertView addTextFieldWithValue:@"" label:@"Mot de passe"];
// Username
textfieldName = [alertView textFieldAtIndex:0];
textfieldName.keyboardType = UIKeyboardTypeAlphabet;
textfieldName.keyboardAppearance = UIKeyboardAppearanceAlert;
textfieldName.autocorrectionType = UITextAutocorrectionTypeNo;
// Password
textfieldPassword = [alertView textFieldAtIndex:1];
textfieldPassword.clearButtonMode = UITextFieldViewModeWhileEditing;
textfieldPassword.keyboardType = UIKeyboardTypeNumbersAndPunctuation;
textfieldPassword.keyboardAppearance = UIKeyboardAppearanceAlert;
textfieldPassword.autocorrectionType = UITextAutocorrectionTypeNo;
textfieldPassword.secureTextEntry = YES;
[alertView show];
这是代码，收到此错误：
// Ask for Username and password.
UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:_title message:@"\n \n \n" delegate:self cancelButtonTitle:@"Cancel" otherButtonTitles:@"OK", nil];
// Adds a username Field
textfieldName = [[UITextField alloc] initWithFrame:CGRectMake(12.0, 45.0, 260.0, 25.0)];
textfieldName.placeholder = @"Login";
[textfieldName setBackgroundColor:[UIColor whiteColor]];
textfieldName.enablesReturnKeyAutomatically = YES;
[textfieldName setReturnKeyType:UIReturnKeyDone];
[textfieldName setDelegate:self];
[alertView addSubview:textfieldName];
Show alert on screen.
[alertView show];
[alertView release];
感谢您的帮助我！
苹果为什么拒绝你的应用程序？你为什么要访问'UIViewController'的'._title'属性？这可能是一个私人/不支持的事情。最好放置（并访问）你的'title'属性到你的子类视图控制器中。 – 2012-01-31 10:17:27
@迈克尔：感谢您的快速询问。因为“我们在你的应用程序中发现了以下非公开API/s：addTextFieldWithValue：label：”儿子我正在尝试该代码：http：//stackoverflow.com/questions/3784134/any-non-private-api-alternative -for-this – clement 2012-01-31 10:18:44
@Michael：如果我评论了我编辑的代码，应用程序就会生成，因此我编辑了我的第一篇文章;-) – clement 2012-01-31 10:25:40
