Question

is is possible to access objects using variables in a FOR statement?

Say i have declared:

UIImageView *UIImageView0;
UIImageView *UIImageView1;
UIImageView *UIImageView2;

and i have 3 objects in an array and i call a FOR statement if x in the array is equal to 2 i want it to add the value of x to the UIImageView name like UIImageView1 etc

I have tried:

for (int x=0; x<[theArray count]; x++) {

UIImageView[x].image = etc....

}

but it gives me a error on UIImageView[x]

subscript requires size of interface 'UIImageView'

any ideas? or is it even possible with a UIImageView?

Thanks

You don’t have three elements in an array, though; you have three independent variables with similar names. If you created an actual array, containing the values of the three variables, then you could use the for loop — and in fact, the syntax would be just as you’ve shown (using the actual name of the array variable, of course.)

You could say

UIImageView * views[3] = {UIImageView0, UIImageView1, UIImageView2};

and then use, for example, views[i].image in your loop.
