access UIView objects in array

i´ve defined an a开发者_如何学Gorray which contents 4 UIView objects which were already defined

NSArray *districtArray = [NSArray arrayWithObjects:view1, view2, view3, view4, nil];

now i´d like to add a subview to an UIView accessing the array via an index. i can´t figure out how i have to write that

it should be something like that

[districtArray[0] addSubview:poiObject];

could anybody give me a hint about the syntax?

thank you!

To get the n-th object in an NSArray, use

[array objectAtIndex:n]

e.g.

[[districtArray objectAtIndex:0] addSubview:poiObject];

Edit: Starting from Xcode 4.4 (2012 Jul) OP's syntax is supported, i.e.

[districtArray[0] addSubview:poiObject];

does work as expected. This is known as object subscripting.
