Question

New to Cocoa, and seem to be missing something.

What is the most elegant/idiomatic way to obtain the first x elements of an NSArray as another NSArray? Obviously I can iterate through them and store them manually, but it seems like there has to be a more standard method of doing this.

I was expecting there to be an -arrayWithObjectsInRange: or something similar, but don’t see anything…

NSArray* largeArray...// Contains 50 items...

NSArray* smallArray = // fill in the blank     

// smallArray contains first 10 items from largeArray

Thanks!

You can use subarrayWithRange:.

NSArray *smallArray = [largeArray subarrayWithRange:NSMakeRange(0, MIN(10, largeArray.count))];//MIN() used because array must be larger than or equal to range size, else exception will be thrown
