Question

I have an array “myArr” which contains objects of custom class..e.g. objs of type MyClass

I need to share this array across multiple classes..

Could you please help me with the exact code that I should be using..

I have referred Singleton patter on Apple and other references, but it is all ver confusing to me…So it will be great if you could highlight the things/code that I need to add.

Answer 1

I recommend that you read up on object delegation.

@property (nonatomic,copy) NSArray *myArr;

On your other classes, implement a delegate object that will point to this class, then you could use:

NSArray *retrievedArray = [self.delegate myArr];

Edit: If you are interested to use only Singleton i believe it would be something along this way:

static MyClass *obj = nil;

On your class with the array, create a class method to return a Singleton object

+(MyClass*) sharedInstance {

     if (obj) {

      obj = [[self alloc]init];

     }

return obj;

}

On your other classes you could just use

NSArray *retrievedArray = [[MyClass sharedInstance] myArr];

to get back the array.

Cheers.
