This solution is in Objective C

UIImage *settingImageName = [UIImage imageNamed:@"Menu_Burger_Icon"];
UIButton * settingButton = [UIButton buttonWithType:UIButtonTypeCustom];
[settingButton setImage:settingImageName forState:UIControlStateNormal];
[settingButton addTarget:self action:@selector(settingsBtnClicked) forControlEvents:UIControlEventTouchUpInside];
settingButton.frame = CGRectMake(0, 0, 30, 30);

UIBarButtonItem *settingBarButton = [[UIBarButtonItem alloc] initWithCustomView:settingButton];

UIImage *notificationImageName = [UIImage imageNamed:@"NotificationON"];
UIButton * notificationButton = [UIButton buttonWithType:UIButtonTypeCustom];
[notificationButton setImage:notificationImageName forState:UIControlStateNormal];
[notificationButton addTarget:self action:@selector(notificationButtonClicked) forControlEvents:UIControlEventTouchUpInside];
notificationButton.frame = CGRectMake(0, 0, 30, 30);
UIBarButtonItem *notificationBarButton = [[UIBarButtonItem alloc] initWithCustomView:notificationButton];

self.navigationItem.rightBarButtonItems  = @[settingBarButton,notificationBarButton];
