how to fix this memory leak?

- (void)addChild:(MyTreeNode *)newChild {
    newChild.parent = self;
    [self checkForSelectedNode:newChild];
    [self.children addObject:newChild];

}

In this code children is a property of the class used.The line [self.children addObject:newChild];

is showing 100 % leak when debugging with instruments. it is properly released in the dealloc method.still it is showing leak.how to remove this leak?

In the header of MyTreeNode the parent property should be assign not retain. Other wise there are retain cycles and memory leaks.

Explanation: Down one level the node is retaining it's parent and the parent is retaining it's child. This retain cycle will keep itself from releasing.
