为什么在Xcode 5 / iOS 7的iPhone上测试应用程序会因调用NSLog而崩溃？

Question

I've completed adapting my app for iOS 7 in Xcode 5, and it has tested fine in the simulator (for both iOS 7 and 6.1). Before deploying for testing, I've run it a few times on my iPhone from Xcode 5, but the app frequently crashes with the error message:

error: failed to launch 'app name/path' -- failed to get the task for process ####

I narrowed this down to NSLog calls. This never happened before using the iOS 6 SDK. Anyone know why this is the case? Is it not good practice to have a few NSLogs in an app (even for reporting errors/warnings to the user's console)?

Answer 1

Calling NSLog should not be a problem.

Cleaning Derived Data and changing my provisioning profile has helped for me.
