iOS development: Add multiple buttons to the navigation bar and add logos to the left

Add multiple buttons, and you can add just one

Uibarbuttonitem *anotherbutton = [[Uibarbuttonitem alloc] initwithtitle:nslocalizedstring (@ "register", nil) style: Uibarbuttonitemstyleplain target:self Action: @selector (Registerclick:)];            Uibarbuttonitem *anotherbutton2 = [[Uibarbuttonitem alloc] initwithtitle:nslocalizedstring (@ "login", nil) style: Uibarbuttonitemstyleplain target:self Action: @selector (Loginclick:)];            [Self.navigationitem Setrightbarbuttonitems:[nsarray Arraywithobjects:anotherbutton,anotherbutton2,nil];

Add logo, only on the first page, use the following method

Self.sharenavleftview = [[UIView alloc] init];        Self.shareNavleftView.frame = CGRectMake (0.0, 0.0, 191.0, 47.0);        Uiimageview *img = [[Uiimageview alloc] init];        Img.image = [UIImage imagenamed:@ "Oatoslogo.png"];        Img.autoresizingmask = Uiviewautoresizingflexiblewidth;        Img.frame = Self.shareNavleftView.frame;        [Self.sharenavleftview addsubview:img];        Self.navigationItem.leftBarButtonItem = [[Uibarbuttonitem alloc] initWithCustomView:self.shareNavleftView];

In this way, the logo will be added to each of the following pages, do not meet my needs

[Self.navigationController.view AddSubview:self.shareNavleftView];
