Objectivec iPhone：在 UITextField 上禁用 AutoCapautocorrect 问题

出于某种原因，尽管我禁用了UITextField的自动cap和自动更正功能，但它仍然将输入的第一个字母大写.

以下是代码:

UITextField* textField = [[[UITextField alloc] initWithFrame:CGRectMake(90.0, 10.0, 213.0, 25.0)] autorelease];
[textField setClearButtonMode:UITextFieldViewModeWhileEditing];
textField.returnKeyType = UIReturnKeyGo;
textField.autocorrectionType = FALSE;
textField.autocapitalizationType = UITextAutocapitalizationTypeNone;
textField.delegate = self;
if (inputFieldType == Email) {
    label.text = @"Email:";
    textField.keyboardType = UIKeyboardTypeEmailAddress;
    emailTextField  = textField;
    textField.placeholder = @"Email Address";
} else { // password
    textField.secureTextEntry = TRUE;
    label.text = @"Password:";
    if (inputFieldType == Password){
        textField.placeholder = @"Password";
        passwordTextField  = textField;
    }
    if (inputFieldType == ConfirmPassword){
        textField.placeholder = @"Confirm Password";
        confirmPasswordTextField  = textField;
    }

}
