NSMutableArray *originalArray = [self arrayFromCloudKit]; // fetch from CloudKit
// now the user wants it sorted alphabetically
NSMutableArray *alphabeticallySorted = originalArray.mutableCopy
[alphabeticallySortedsortUsingSelector:@selector(localizedCaseInsensitiveCompare:)];
[self storeOriginalArray:originalArray];
[self displayUIWithArray:alphabeticallySorted];
// but if the user changes their mind, you just fetch the original and delete the sorted
NSMutableArray *originalArray = [self getOriginalArray];
[self displayUIWithArray:originalArray];
