                                                               message:@"This is an alert."
                                                        preferredStyle:UIAlertControllerStyleAlert];

[alert addTextFieldWithConfigurationHandler:^(UITextField *textField) {

    textField.placeholder = @"This is my placeholder";
    textField.backgroundColor = [UIColor colorWithRed:246.0/255.0 green:246.0/255.0 blue:246.0/255.0 alpha:1.0]; // You can change it to whatever color you want
    [textField superview].backgroundColor = textField.backgroundColor;
    [[textField superview] superview].backgroundColor = [UIColor whiteColor];

}];
