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.
