Thanks all. I got it working, indeed the Scanner was failing, which as Kiel suggested, must have led to an invalid pointer by the time I tried to log/return it. Once I checked the BOOL it quit crashing and then with some reworking of my NSScanner code it processed and returned the string I wanted.
Thanks again for the help. --chris On Oct 15, 2010, at 12:08 PM, Kiel Gillard wrote: > http://developer.apple.com/library/ios/documentation/cocoa/reference/foundation/Classes/NSScanner_Class/Reference/Reference.html#//apple_ref/occ/instm/NSScanner/scanCharactersFromSet:intoString: > > You pass by reference to the - [NSScanner scanCharactersFromSet:intoString:] > method an uninitialised pointer to a NSString object. > > Consider the return value of the - [NSScanner > scanCharactersFromSet:intoString:] method.
