NSMutable Array and leaking Problem

Question

Hey - does somebody know why i get a leak when i use this line of code ??? :

[self setModules:[[aDictionary objectForKey:KEY_MODULES] mutableCopy]];

Thanks in advance pk

Answer 1

As you create a copy of existing object via mutableCopy then you're responsible to release it (assuming you also retain it in setModules method):

[self setModules:[[[aDictionary objectForKey:KEY_MODULES] mutableCopy] autorelease]];

Check also that you release modules iVar in your class's dealloc method.

Answer 2

mutableCopy creates a new copy with a retainCount of 1 and needs to be released.

[self setModules:[[[aDictionary objectForKey:KEY_MODULES] mutableCopy] autorelease]];
