objective c reload Rows At

To reload rows in Objective-C, you can use the reloadRowsAtIndexPaths:withRowAnimation: method. This method is used to reload specific rows in a table view, and it requires two parameters: an array of index paths representing the rows to reload, and an animation style for the reload.

Here's an example of how to use the reloadRowsAtIndexPaths:withRowAnimation: method:

// Create an array of index paths for the rows you want to reload
NSIndexPath *indexPath1 = [NSIndexPath indexPathForRow:0 inSection:0];
NSIndexPath *indexPath2 = [NSIndexPath indexPathForRow:1 inSection:0];
NSArray *indexPaths = @[indexPath1, indexPath2];

// Call the reloadRowsAtIndexPaths:withRowAnimation: method
[self.tableView reloadRowsAtIndexPaths:indexPaths withRowAnimation:UITableViewRowAnimationFade];

In this example, we create an array indexPaths that contains two index paths representing the rows at index 0 and 1 in section 0. Then, we call the reloadRowsAtIndexPaths:withRowAnimation: method on the table view (self.tableView) and pass in the indexPaths array and a desired animation style (UITableViewRowAnimationFade in this case).

This will reload the specified rows in the table view with a fade animation. You can choose from different animation styles according to your needs, such as UITableViewRowAnimationAutomatic, UITableViewRowAnimationLeft, UITableViewRowAnimationRight, and more.

Make sure to call this method within a block that is executed on the main thread, as UI updates should always be performed on the main thread in Objective-C.
