Memory Leak In line of code

Question

My app is working fine, but when I run instrument for checking for leaks, it shows me a leak at this line of code, in purple with a 100.0% mark:

xmlParser = [[NS         


        

Answer 1

You never release FinalString (at least not in the code you posted)

this is held in the URL, which is held by the parser :)

Also, have you considered what would happen if this function is called twice?

Each time you say

xmlParser = [[NSXMLParser alloc] initWithContentsOfURL:url];

you would leak the previous xmlParser ;)

If you are allocating to an instance variable, you have to remember to release the previous object i.e.

[xmlParser release];
xmlParser = [[NSXMLParser alloc] initWithContentsOfURL:url];
