Memory leak regarding NSRange

Question

NSString *mob = (__bridge_transfer NSString *)ABMultiValueCopyValueAtIndex(mobNum, emailCounter);
                mob = [ApplicationSingleton FindMobileNumber:mob];
                if ([favos rangeOfString:mob].location != NSNotFound)

it gives below message when checking for memory leaks...

the receiver of message "rangeOfString:" is nil and returns a value of type NSRange that will be garbage

can anyone please help me... Thanks in advance...

Answer 1

It seems that favos is nil. Make sure that the variable is set in all code paths, or check it for nil.
