Change duration of UITableView animation (Insert/Delete rows with table beginUpdates)

Question

Is there a way to change the duration of [table beginUpdates]/[table endUpdates] animations?

This is what I\'ve tried, with no luck:

@Gautam Jain 's solution is great. However, it has a problem, at least in iOS 9: the completion block will be executed at once but not when the animation completes.

I usually do like below, with a little more code but works better.

[UIView beginAnimations:@"animation" context:nil];
[UIView setAnimationDuration:0.25];
[CATransaction begin];
[CATransaction setCompletionBlock:^{
   // completion block
}];

[self.tableView beginUpdates];
// updates  
[self.tableView endUpdates];

[CATransaction commit];
[UIView commitAnimations];
