Re: debugging unrecognized selector
I believe the intention of the slider is that it won't drop you to stack frames that does not have your code (and show you with assembler) but it can be troublesome. When LLDB break your program at signal your program could have already progressed past where the exception happened and already popped all the way back to main(). When diagnosing selector not found you should break on [NSObject doesNotRecogniseSelector:] or [NSObject forwardInvocation:] Sent from my iPhone > On May 16, 2014, at 10:38 PM, Kyle Sluder wrote: > > On May 16, 2014, at 3:07 AM, Torsten Curdt wrote: > >>> the debugger only stops in UIApplicationMain. >>> >>> That’s most likely because your “level of detail” slider (the horizontal >>> slider below the call stack in the Debug pane) isn’t at the extreme right >>> end. >> >> OMG!

Re: debugging unrecognized selector
Strings does not have CGColor methods so it is not caught.
