How to update a UITableVIewCell without reloading full table [duplicate]

Answer 1

As you are making a GUI update, it's better to use reloadData rather then using any other methods. reloadData is the best way in your case to update the UITableView as it avoids inconsistency. The other thing which you can do is, you can add a condition in your cellForRowAtIndexPath and let execution happen only for the cell which is modified.

Answer 2

If you're just adding one item, and you wish to have that added to the table, you can manually insert it into your UITableView, here's an example:

NSIndexPath *indexPath = [NSIndexPath indexPathForRow:_directions.count-1 inSection:0];
NSArray *indexPaths = [NSArray arrayWithObject:indexPath];
[self.tableView insertRowsAtIndexPaths:indexPaths withRowAnimation:YES];

Answer 3

You can use this..

NSArray *indexPathArray = [NSArray arrayWithObject:[NSIndexPath indexPathForRow:1 inSection:0]];
//You can add one or more indexPath in this array...

[tblview reloadRowsAtIndexPaths:indexPathArray withRowAnimation:UITableViewRowAnimationFade];

Answer 4

You can get the cell object by -

UITableViewCell *cell = [table cellForRowAtIndexPath:indexPath];

now change its related values as per your object from data array. It should reflect in the table. Hope this helps.

Answer 5

 - (void)reloadRowsAtIndexPaths:(NSArray *)indexPaths withRowAnimation:(UITableViewRowAnimation)animation;

Use this

Answer 6

You can reload particular image row using index path .

    [mainTableView reloadRowsAtIndexPaths:[NSArray arrayWithObject:indexPath]
                         withRowAnimation:UITableViewRowAnimationNone];
