[ios] where to find your iphone app on your mac during debuging

some time we need to figure out if any resoures files are already packed in the app. we can find it from mac under the path as below, in this case the app name is 3dhw:

/Users/dingqun2008/Library/Developer/Xcode/DerivedData/3dhw-dychilwmyhglaeaalsypvckomsud/Build/Products/Debug-iphoneos/3dhw.app/3dhw

basically, you can go to ~/Developer/Xcode/DerivedData/ to find yours.
