NSSortDescriptor Not Sorting Array

Question

I am using NSSortDescriptor to sort my array on the basis of a key. Yesterday the same code was working very fine. But today its not sorting my array. I dont know what happened. There is not even a single code change.

Here is my code

NSSortDescriptor *sort = [[NSSortDescriptor alloc] initWithKey:keyName ascending:is_asc];
NSArray *temp = [arrayDFRValues sortedArrayUsingDescriptors:[NSArray arrayWithObject:sort]];
arrayDFRValues = [NSMutableArray arrayWithArray:temp];
[self.myTableView reloadData];

Please anyone can help?

Answer 1

NSSortDescriptor * sort = [[NSSortDescriptor alloc] initWithKey:@"keyName" ascending:YES];
NSArray *sortDesc = [NSArray arrayWithObject:sort];
[arrayDFRValues sortUsingDescriptors:sortDesc];
[self.myTableView reloadData];
