Question

I made a linked list and a global start variable for it.
I am trying to access the same linked list from its start node in an other class but its value is lost after the viewDidLoad method.
From viewDidLoad I am able to traverse the list but not from other methods..I guess its autoreleasepool in play how can I retain the start value of the start pointer?
the node structure is

struct Movenode{
    NSMutableString *comment;
    NSMutableString *move;
    struct Movenode *variationLink;
    struct Movenode *nextLink;
    struct Movenode *goBack;
};


//viewDidLoad  Metod
- (void)viewDidLoad
{
    [super viewDidLoad];

    myNode=START;
    While(myNode!=NULL)
    {
      NSLog(@"%@",myNode->move);
      myNode=myNode->nextLink;
    }
//it works fine here
}

-(void)otherMethod
{

myOtherNode=START;
while(myOtherNode!=NULL)
{
NSLog(@"%@",myOtherNode->move);//this line will give bad access there is no value in move.
myOtherNode=myOtherNode->nextLink;
}
}

Answer 1

solved the problem by
1.insted of structure i used class.
2.i declared the START variable in app delegate.

using class allowed me to call retain on its objc i can now very well access the linked list from any where
