Question

I have a class level NSMutableDictionary object that I need to initialize, and reinitialize. Since my project is ARC, I am not sure if I can use release.

What is correct way to do it?

My current code results into a crash:

myDict = [[NSMutableDictionary alloc] initWithObjectsAndKeys: value1,@"key1", 
value2,@"key2", nil];

Note that this crash is when I do this 2nd time after class is loaded, not the first time. So the problem is definitely that I am re-allocating it.

In any case (crash or not), I want a leak-free way to handle this in an ARC project.

I think you need to do like that

 -(void)ViewDidLoad
 {
      [super viewDidLoad];
      myDict =  [[NSMutableDictionary alloc] initWithObjectsAndKeys: value1,@"key1", value2,    @"key2", nil];
 }

when you re using it please do not alloc/init again instead you can do as following

if([[myDict allKeys]count])
{
     [myDict removeAllObjects];
}

and set again value inside the dictionary

 [myDict setValue:@"Abc" forKey:@"xyz"];
