How to sort tableview rows?

Sorting the data source and then triggering a reload of the tableview should be an option.

Here is how I do it with NSMutableArray objects when I need to sort ascending on a string property: (descending add ! after return before bracket: "return ![...")

NSMutableArray *dataToSort = [data mutableCopy];
[dataToSort sortUsingComparator:^NSComparisonResult(MyObject *obj1, MyObject *obj2) {
     return [obj1.aString localizedCompare:obj2.aString];
}];
data = dataToSort;
[self.tableView reloadData];

If your array contains NSDictionary objects, you can also sort by a specific object within the dictionary, e.g.:

NSSortDescriptor *sortByName = [NSSortDescriptor sortDescriptorWithKey:@"dictionaryKey1" ascending:YES];
NSArray *sortDescriptors = [NSArray arrayWithObject:sortByName];
self.tableData = [[self.tableData sortedArrayUsingDescriptors:sortDescriptors]mutableCopy];
[self.tableView reloadData];

I tried this and it doesn't work , output: unrecognized selector sent to instance 0x7f9773609ee0

It seems compare not the array's contents but an address...

@interface ListOfProductsTableViewController ()

@property NSMutableArray *products;

@end

@implementation ListOfProductsTableViewController

// When user taps A-z button sort list of products ascending

- (IBAction)Ordena:(UIBarButtonItem *)sender {

[self.produtos sortUsingSelector:@selector(caseInsensitiveCompare:)];

[self.tableView reloadData];

After hours (and days) reading guides manuals, etc. etc. I found the right way:

NSSortDescriptor *produtoDescriptor = [[NSSortDescriptor alloc]

initWithKey:@"itemName" ascending:YES selector:@selector(localizedStandardCompare:)];

NSArray *sortDescriptors = @[produtoDescriptor];

self.products = [[self.products sortedArrayUsingDescriptors:sortDescriptors]mutableCopy];

[self.tableView reloadData];

Thank You!

My advice :You'd better check the custome method named (LocalizedStandardCompare)
