If every element in the array is a dictionary containing a certain key, you can sort the array using a sort descriptor. For instance, if every element is a dictionary containing a key called "name":

NSSortDescriptor *sortByName = [NSSortDescriptor sortDescriptorWithKey:@"name"
    ascending:YES];
NSArray *sortDescriptors = [NSArray arrayWithObject:sortByName];
NSArray *sortedArray = [array sortedArrayUsingDescriptors:sortDescriptors];

The other way to achieve this would be using sortedArrayUsingComparator: method

NSArray *sortedArray = [array sortedArrayUsingComparator:^NSComparisonResult(id obj1, id obj2) {
    return [[obj1 valueForKey:@"value"] compare:[obj2 valueForKey:@"value"]];
}];

why don't you use a sorted dictionary where the property of sorted elements comes already with the data structure?

Hope this helps.

The above shared answer by Bavarious helped me.Just want to add one more thing.If you want to sort a mutable array use something like the below code

NSSortDescriptor *sortByName = [NSSortDescriptor sortDescriptorWithKey:@"name" ascending:YES];
NSArray *sortDescriptors = [NSArray arrayWithObject:sortByName];
NSMutableArray *sortedArray = [[NSMutableArray sortedArrayUsingDescriptors:sortDescriptors]mutableCopy];

 let arrDescriptor = NSSortDescriptor(key: "order", ascending: true)
 let sortDescriptors: NSArray = [arrDescriptor]
 let sortedArray = instancesubArray.sortedArray(using: sortDescriptors as [AnyObject] as [AnyObject] as! [NSSortDescriptor])

 print(sortedArray)

Please use the [edit] link to explain how this code works and don't just give the code, as an explanation is more likely to help future readers. See also [answer]. – Jed Fox Jun 28 '17 at 18:56
