问题
When I use wireless debugging in Xcod e4.2 it tells me:
Don't know how to run. Try "help target".
Please see "Wireless debugging in xcode" for more information.
回答1:
Wireless debugging in Xcode 4.2 is still really unstable. I've only been able to get it up and running once or twice before needing to restart Xcode, disabling and reenabling wireless device support, restarting the device, and deleting the app from the device before trying it again (not necessarily in this order).
Hopefully they'll get it working better soon.
