I have two arrays, A and B.
How can I remove elements from A, if those elements exist in B?
e.g. Array A:{1,2,3,4,5}, array B:{1,3}
I would like to remove 1 and 3 from array A such that array A only contains 2,4,5 after the operation.
Besides looping, is there any more efficient approach to doing it?
You have the removeObjectsInArray:
method from NSMutableArray
. It does what you want.
