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. If the method fails to scan the given characters and returns NO, your theScannedString pointer is probably still invalid.
