int FIELD = [testController getField:point];
-> now I want to call imageViewFIELD.image = ...

Yeah you want an array. What you're trying to do isn't possible, though by using an array you can achieve the same result.
Look at the NSArray [developer.apple.com] class reference to get yourself started.
Code:
NSArray * imageViews = ...;
int FIELD = [testController getFieldPoint];
[[imageViews objectAtIndex:FIELD] setImage:...];Look at the NSArray [developer.apple.com] class reference to get yourself started.
