update UITableView based on array - objective-c

Question

I have JSON file who's information I put in my table. I have one button for sorting my array
I can sort my array and print it with NSLog. How can I update my table based on my sorted array?
This is my code:
-(void)sortArry:(UIButton *)sender
{
NSSortDescriptor *ageDescriptor = [[NSSortDescriptor alloc] initWithKey:#"name" ascending:YES];
NSArray *sortDescriptors = #[ageDescriptor];
NSArray *sortedArray = [tableData sortedArrayUsingDescriptors:sortDescriptors];
//here i have my data in nslog
NSLog(#"%# sort test",sortedArray);
}
How can I show my sortedArray in the table?
I also used
[self.tableView reloadData];
after sorting but it didn't show the sorted table
Update:
Here is my cellForRowAtIndexPath
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath
*)indexPath
{
static NSString *CellIdentifier = #"Cell";
CustomCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
NSArray *objects = [[NSBundle mainBundle] loadNibNamed:#"CustomCell" owner:nil options:nil];
for (id currentObject in objects)
{
if([currentObject isKindOfClass:[UITableViewCell class]])
{
cell = (CustomCell *) currentObject;
break;
}
}
}
id keyValuePair;
if (tableView == self.searchDisplayController.searchResultsTableView)
{
keyValuePair = [self.filteredTableData objectAtIndex:indexPath.row];
}
else
{
keyValuePair = [self.tableData objectAtIndex:indexPath.row];
}
cell.name.text = keyValuePair[#"name"];
return cell;
}

Answer 1

sortedArray is deleted when it goes out of scope at the end of your sortArry: method. You need to set the property or instance variable that your UITableViewDelegate methods inspect.

Answer 2

Call [tableView reloadData]; after the array is sorted.

Answer 3

sortedArray needs to be a property of your viewController not an instance variable of sortArry , so when you reload all UITableViewdelegate method can access its values and update.
// The array You use to populate the table
#property NSArray ArrayDataSource;
Change the method signature to return the sorted array
-(NSArray *)sortArry
{
NSSortDescriptor *ageDescriptor =
[[NSSortDescriptor alloc] initWithKey:#"name" ascending:YES];
NSArray *sortDescriptors = #[ageDescriptor];
NSArray *sortedArray =
[tableData sortedArrayUsingDescriptors:sortDescriptors];
//here i have my data in nslog
NSLog(#"%# sort test",sortedArray);
return sortedArray;
}
Stored the return value in the datasource:
ArrayDataSource = [self.ArrayDataSource];
Finally reload the table
[self.tableView reloadData];
