How to wait for the completion of the embedded animation UITableView?

Question

[self.tableView reloadSections:[NSIndexSet indexSetWithIndexesInRange:NSMakeRange(0, 1)] withRowAnimation:UITableViewRowAnimationLeft]; [self.tableView reloadRowsAtIndexPaths:@[ [NSIndexPath indexPathForItem:1 inSection:1]] withRowAnimation:UITableViewRowAnimationRight]; 

In the above code, how to execute the second line after completing the animation from the first line?

I tried this ...

 [self.tableView beginUpdates]; [self.tableView reloadSections:[NSIndexSet indexSetWithIndexesInRange:NSMakeRange(0, 1)] withRowAnimation:UITableViewRowAnimationLeft]; { [self.tableView beginUpdates]; [self.tableView reloadRowsAtIndexPaths:@[ [NSIndexPath indexPathForItem:1 inSection:1]] withRowAnimation:UITableViewRowAnimationRight]; [self.tableView endUpdates]; } [self.tableView endUpdates]; 

and this...

 [self.tableView beginUpdates]; { [self.tableView reloadSections:[NSIndexSet indexSetWithIndexesInRange:NSMakeRange(0, 1)] withRowAnimation:UITableViewRowAnimationLeft]; } [self.tableView endUpdates]; [self.tableView beginUpdates]; { [self.tableView reloadRowsAtIndexPaths:@[ [NSIndexPath indexPathForItem:1 inSection:1]] withRowAnimation:UITableViewRowAnimationRight]; } 

... but in any case, the animation clearly happens at the same time (and is really obvious with slow animation).

Thanks to Iducool for pointing me to another question.

It worked ...

 [CATransaction begin]; [CATransaction setCompletionBlock:^{ [self.tableView reloadRowsAtIndexPaths:@[ [NSIndexPath indexPathForItem:1 inSection:1]] withRowAnimation:UITableViewRowAnimationRight]; }]; [self.tableView reloadSections:[NSIndexSet indexSetWithIndexesInRange:NSMakeRange(0, 1)] withRowAnimation:UITableViewRowAnimationLeft]; [CATransaction commit]; 

I did not need the UITableView beginUpdates and endUpdates .
