I created a totally new project with the tool “create_project.py”. Build succeeded on both IOS and Mac, but the “Product->Run” is gray on both platform.
The result is when press the triangle button at the top left corner of Xcode, on Mac the app will not start and on IOS the emulator won’t show up.
It’s really strange that I created a successful project that can build and run in the same way just yesterday.
Mac OS X 10.8.5, Xcode 5.0, cocos2d-x 2.2.
Thanks for help.
