iphone - UIAlertViewStylePlainTextInput未声明

当该属性应在框架中可用时，我一直在获取未声明的属性。

UIAlertView * alert = [[UIAlertView alloc] initWithTitle:@"Email Alert" message:@"Enter your Email Address" delegate:self cancelButtonTitle:@"Hide" otherButtonTitles:nil];
[alert setAlertViewStyle:UIAlertViewStyleSecureTextInput];
[alert show];
[alert release];

最佳答案

我已经以这种方式使用UIAlertViewStylePlainTextInput。请根据需要修改代码。

                 alertType = @"phoneNumberAlert";
                 UIAlertView *phoneNumberAlert = [[UIAlertView
                 alloc]initWithTitle:@"Notice"
                 message:@"Please enter your Phone Number" delegate:self
                 cancelButtonTitle:nil otherButtonTitles:@"Ok", nil];
                 [phoneNumberAlert setAlertViewStyle:UIAlertViewStylePlainTextInput];
                 UITextField *alertTextField = [phoneNumberAlert textFieldAtIndex:0];
                 alertTextField.keyboardType = UIKeyboardTypeNumberPad;
                 [phoneNumberAlert show];
                 [phoneNumberAlert release];
