Question

I have an NSMutableArray something like this

array =[[a1,b1,c1],[a2,b2,c2],[a3,b3,c3].......]

and I access this array for particular object like

array.a =[a1,a2,a3]
array.b =[b1,b2,b3]

something like this arrayABC = [a1,a2,a3....]

HOw can i do that.. suggestions are always appreciated..

You could use the "arrayWithArray" class method in NSArray:

NSArray *newABC = [NSArray arrayWithArray:someOtherArray];
