Is there a possible source that I could test the iphone controls in my unity iphone project without having to build it or using either an actual device or a simulator?
Yup, it called unity remote. You can download it off the iphone app store and then connect your ipod to your computer and control your computer wirelessly with your ipod, iphone, or ipad. However, I would recommend that you turn off the show image option because it drastically slows down the response time.
the remote app is a good option for testing touch controls.
if it’s a one-touch game, you can also just set it up to use Input.GetButton(“Fire1”) instead of Input.touches, which will allow you to test the controls in the editor using the mouse.
