使用VCFloatingActionButton可可。为了获得更好的动画，按钮隐藏菜单，请使用下面的代码。

-(void) dismissMenu:(id) sender

{
    [UIView animateWithDuration:animationTime / 2 animations:^{
        self.pressedImageView.alpha = 0.0f;
        self.pressedImageView.transform = CGAffineTransformMakeRotation(M_PI/2);
        self.normalImageView.transform = CGAffineTransformMakeRotation(0);
        self.normalImageView.alpha = 1.0f;

        [UIView animateWithDuration:0.3f animations:^{

            [self.bgView setAlpha:1.0f];
            NSMutableArray* arrayIndexpath = [[NSMutableArray alloc] init];
            while (noOfRows > 0) {
                noOfRows -= 1;
                NSIndexPath* indexPath = [NSIndexPath indexPathForRow:noOfRows inSection:0];
                [arrayIndexpath addObject:indexPath];
            }
            [_menuTable deleteRowsAtIndexPaths:arrayIndexpath withRowAnimation:UITableViewRowAnimationFade];
            [_menuTable reloadData];

        }
            completion:^(BOOL finished) {

                [UIView animateWithDuration:0.3f animations:^{

                    [self.bgView setAlpha:0.0f];

                }
                                 completion:nil];

            }];

    }
        completion:^(BOOL finished){

        }];
}
