EXC_BAD_ACCESS from Unity::Material::CreateMaterial When running simple app on iPhone.
Hi There,
This is my first foray into iPhone dev from Unity and its not going well. I'm getting a EXC_BAD_ACCESS error when I try to run my ap on my testing iPhone. It would be great if anyone can help me figure out what is doing this, I've seen other people having issues with UI Materials but nothing that fits this. It freezes and hangs at the Unity logo screen when I try to run this. If you want more info just let me know what you'd like to see. I'm running Unity 4.6.1f1 . It runs without complaint in the editor. I'm new to the iPhone debugging process so even if you could point me in the right direction it would be helpful. Thanks so much,
Dylan

just to add, I'm using the new 4.6 UI system so I suspect its something from that. The scene has literally no scripts but is just a Canvas with some panels and buttons.
Ok, I figured it out. Its actually a pretty simple solution, I just had an empty material in the UI panel and that won't throw an error until you get to trying to run it on iOS. A warning would be nice but at least its a simple solution.
hi. I got same error as you. could you share the detail of your solution with me? does empty material mean that just dummy material to skip error? and is UIpanel on NGUI? Please let me know.
Could you please provide more information about material you changed. I have the same issue and can't solve it.
Maybe the you forget to point the default shader like the UIDefault.shader to loaded!!
I had this problem and traced it to using Unity's built in Lucida font. Changed to Aerial and no problems. Using NGUI.
The old font simply broke everything else visually.
