Leak in NSScanner category method
- by jluckyiv
I created an NSScanner category method that shows a leak in instruments.
- (BOOL)scanBetweenPrefix:(NSString *)prefix
andSuffix:(NSString *)suffix
intoString:(NSString **)value
{
NSCharacterSet *charactersToBeSkipped = [self charactersToBeSkipped];
[self setCharactersToBeSkipped:nil];
BOOL result = NO;
// find the prefix; the scanString method below fails if you don't do this
if (![self scanUpToString:prefix intoString:nil])
{
MY_LOG(@"Prefix %@ is missing.", prefix);
return result;
}
//scan the prefix and discard
[self scanString:prefix intoString:nil];
// scan the important part and save it
if ([self scanUpToString:suffix intoString:value]) // this line leaks
{
result = YES;
}
[self setCharactersToBeSkipped:charactersToBeSkipped];
return result;
}
I figure it's the way I'm passing the value to/from the method, but I'm not sure. It's a small leak (32 bytes), but I'd like to do this right if I can. Thanks in advance.
