Call a method after [self.tableView endUpdates] ended

Question

I want to add my sliderButton after the animation has ended but this doesn't work, it adds the button while the deletion of the section is being animated.

    [coursesTable beginUpdates];
    [coursesTable deleteSections:[NSIndexSet indexSetWithIndex:0] withRowAnimation:UITableViewRowAnimationTop];
    [coursesTable endUpdates];
    [self.view addSubview:sliderButton];

Is there a possibility I can call a method that does that for me when the animation ended?

add sliderButton with some animation so that after animation of deletion of the section is complete your button is added. — hchouhan02, Mar 07 '12 at 08:30

I believe that wrapping your table update in animateWithDuration would work:

[UIView animateWithDuration:0.0 animations:^{
    [coursesTable beginUpdates];
    …
    [coursesTable endUpdates];
} completion:^(BOOL finished) {
    // Code to run when table updates are complete.
}];

Other methods that I found suggested here on Stack Overflow did not work for me.

I used this technique at one time and tested it enough to verify that the completion block was called after I called the table's endUpdates method, but rewrote my code so I didn't need it any more before I had completely verified that the animation was actually finished.

Using this method will skip the animating part of the animation and simply complete it instantly, even if you put in a longer duration like 1.0. — Rob Norback, Sep 10 '16 at 19:23

I have also not found the solution of this.I have to use performSelector:withObject:afterDelay: for getting my work done.

[coursesTable deleteSections:[NSIndexSet indexSetWithIndex:0] withRowAnimation:UITableViewRowAnimationTop];

after this the tableview again asks data from its datasource... so all the datasource methods including cellforRow is again called..

i suggest keeping a BOOL is Deleting.

so now do this

    [coursesTable beginUpdates];
        [coursesTable deleteSections:[NSIndexSet indexSetWithIndex:0] withRowAnimation:UITableViewRowAnimationTop];
        [coursesTable endUpdates];
Deleting = YES;

in cellForRow method

{
if (index path.row == lastrow ) // last rowcell is reached
if(Deleting)
{
//tableView has reloaded.
    [self.view addSubview:sliderButton];
    Deleting = NO;;


}
}

Call a method after [self.tableView endUpdates] ended
