incompatible pointer types assigning to 'nsmutablearray ' from 'nsarray ' in Objective C

Question

users = [users arrayByAddingObjectsFromArray:arrayvalue];

users is a NSMutableArray and arrayvalue is also a NSMutableArray, I am adding value of arrayvalue to the users array but I am getting a warning "incompatible pointer types assigning to NSMutableArray from NSArray ".

I hav searched, but was unable to find a solution for this.

Although arrayvalue is NSMutableArray, the return value of arrayByAddingObjectsFromArray: is NSArray, and that's why you get this warning.

You should call [users addObjectsFromArray:arrayvalue]; which alters the array ~~returnsNSMutableArray~~.

See the NSMutableArray reference for more details.
