i am able to sort only name but not the whole object. Can any one solve this issue for me? It will be very helpful for me... thanks in advance.....

i am using this line to sort the json data sortedArray = [serverData sortedArrayUsingSelector:@selector(localizedCaseInsensitiveCompare:)]; here i am only able to sort single element. But question is how to sort total objects in an array — Charishma Vasamsetti, Aug 17 '17 at 10:03
use "caseInsensitiveCompare:" instead of "localizedCaseInsensitiveC‌ompare:" — phani, Aug 17 '17 at 10:15
*********-[__NSDictionaryI rangeOfString:options:]: unrecognized selector sent to instance******** how can i solve this issue — Charishma Vasamsetti, Aug 17 '17 at 10:37
NSIndexSet* indexes = [sortedArray indexesOfObjectsPassingTest:^BOOL(NSString *string, NSUInteger idx, BOOL *stop){ return [string rangeOfString:[brandsIndexTitles objectAtIndex:i] options:NSCaseInsensitiveSearch | NSDiacriticInsensitiveSearch | NSAnchoredSearch].location != NSNotFound; to display sorted array in table view in alphabetical order — Charishma Vasamsetti, Aug 17 '17 at 10:57
In above question you asked about sorting an array. But here in this code you had taken NSIndexSet. Whats your exact need. — phani, Aug 17 '17 at 11:02
i have already sorted my json data by the code which you have given now my question is when i tap on an alphabet like (when i tap on R) then it has to be moved to particular strings in the list ???? — Charishma Vasamsetti, Aug 17 '17 at 11:05
Up to now I didn't implement this. I don't know how to do that. But your error says "Your trying to get the value which is not exist". may be indexPath:i is wrong. — phani, Aug 17 '17 at 11:25
If you are unable to fix that issue. Send mail to me "phani697@gmail.com". — phani, Aug 17 '17 at 11:58

NSSortDescriptor *sortDescriptor = [[NSSortDescriptor alloc] initWithKey:@"Name" ascending:YES selector:@selector(caseInsensitiveCompare:)];
    [arr sortUsingDescriptors:@[sortDescriptor]];

change it to swift code. Its working. I check this code with NSDictionaries.

in Objective C:(answer of user3306145)

NSSortDescriptor *sortDescriptor = [[NSSortDescriptor alloc]
                                    initWithKey: @"name" ascending: YES];

NSArray *sortedArray = [self.displayItems sortedArrayUsingDescriptors: [NSArray arrayWithObject:sortDescriptor]];

var descriptor: NSSortDescriptor = NSSortDescriptor(key: "name", ascending: true) var sortedResults: NSArray = results.sortedArrayUsingDescriptors([descriptor])
