What is the best/correct way to reverse an NSMutableArray?
901
You can reverse a NSArray by writing your own loop iterating from the end towards the beginning and using a second array to add the items in reverse order. Or you can simply use - (NSEnumerator *)reverseObjectEnumerator from the NSArray class.
The primary difference between NSArray and NSMutableArray is that a mutable array can be changed/modified after it has been allocated and initialized, whereas an immutable array, NSArray , cannot.
The NSMutableArray class declares the programmatic interface to objects that manage a modifiable array of objects. This class adds insertion and deletion operations to the basic array-handling behavior inherited from NSArray .
