I have tried this and my Table is Animated with smooth animation

//Put this code where you want to reload your table view

dispatch_async(dispatch_get_main_queue(), ^{
    [UIView transitionWithView:<"TableName"> 
                      duration:0.1f 
                       options:UIViewAnimationOptionTransitionFlipFromRight 
                    animations:^(void) {
                        [<"TableName"> reloadData];
                    } completion:NULL];        
});

Try Animating while Transition Change of a view while reloading UITableView

[UIView transitionWithView:_yourTableView 
                  duration:0.40f 
                   options:UIViewAnimationOptionTransitionCrossDissolve 
                animations:^(void) {[_yourTableView reloadData];}  
                completion:nil];

You first tell the tableView to expect updates with beginUpdates. Then update the relevant sections (if your tableView has only one section then just pass zero for the section number). Here's where you specify the animation - you can play around with it to get the effect that you want. After that you call endUpdates on the tableView. The typedef for UITableViewRowAnimation specifies:

typedef enum {
   UITableViewRowAnimationFade,
   UITableViewRowAnimationRight,
   UITableViewRowAnimationLeft,
   UITableViewRowAnimationTop,
   UITableViewRowAnimationBottom,
   UITableViewRowAnimationNone,
   UITableViewRowAnimationMiddle,
   UITableViewRowAnimationAutomatic = 100
} UITableViewRowAnimation;

Play around to see which one you want. Even selecting UITableViewRowAnimationNone can have a nice effect sometimes. Table update code below:

    [self.tableView beginUpdates];
    [self.tableView reloadSections:[NSIndexSet indexSetWithIndex:0] withRowAnimation:UITableViewRowAnimationNone];
    [self.tableView endUpdates];
