ARC question


  • Subject: ARC question

Hi folks,

before aught else, all my thoughts to those of you in the Eastern coast that are preparing themselves for a bunch of bleak days…

I’ve just a silly question (I know, I don’t post very often and I apologize for that): I need to convert a HTML style string, with “& escapes” to normal UTF-8. So I wrote this:

-(NSString *)convertHTMLtoUTF8:(NSString *)aString {

	NSString * convertedString = [aString copy];
	for (NSString * pattern in [HTMLtoUTF keyEnumerator]) {
		convertedString = [convertedString stringByReplacingOccurrencesOfString:pattern
									     withString:HTMLtoUTF [pattern]];
	}

	return convertedString;
}

where HTMLtoUTF is a dictionary of pairs {@"&…;" : @"<corresponding_UTF8_char>"}.

Now, my question is: is that scheme going to work correctly with ARC? Is it not going to leak each intermediate version of ‘convertedString’?

Thanks a lot!
Vincent
