How to sort NSMutableArray in objective C [closed]

Answer 1

use this code:

NSArray *sortedArray = [unsortedArray sortedArrayUsingComparator:^(id firstObject, id secondObject) {
    return [((NSString *)firstObject) compare:((NSString *)secondObject) options:NSNumericSearch];
}];

EDIT: If the elements are numbers, change the returned type and the type of the firstObject and secondObject.
