iPad在仪器目标选择中变得灰暗

Question

I'm trying to profile an iPad app in Instruments, but regardsless of which profiling settings I choose, I cannot select the iPad as the profiling target:

If I hover the mouse on "Attach to Process", the only thing I see are grayed out entries for "Application" and "System".

Any hints on the reason why I cannot use Instruments on the iPad?

Answer 1

Make sure that:

• You're using the latest stable Xcode 4.5.x (or newer) since you're targeting the latest iOS stable release;

• Instruments was started by Xcode, eg an old Instruments (from Xcode 4.2) can be started independently (eg by spotlight) and might not support iOS 6.0.1. In doubt check Instruments version;

• Your device is configured for development (look at it inside Xcode organizer, devices);

• Your device's provisioning profiles and developer's identity/certificate are up to date;

Note: you should edit your question and add the XCode version number you're using.
