AUCustomNavigationBar

AUCustomNavigationBar，使用过程中发现，rightItem加不上，测试发现，只有满族下面两个条件才可以显示在相应位置

        [navBar setRightItem:photo];
        [navBar addSubview: photo];

完整代码如下

        AUCustomNavigationBar *navBar = [AUCustomNavigationBar navigationBarForCurrentVC:self];
        [navBar setNavigationBarBlurEffective]; // 毛玻璃效果
        [self.view addSubview:navBar];
        [navBar setBackgroundColor:UIColor.clearColor];
        navBar.title = @"扫码登录";
        navBar.titleColor = UIColor.whiteColor;
        navBar.backButtonTitleColor = UIColor.whiteColor;
        
        AUButton * photo = [[AUButton alloc] initWithFrame:CGRectMake(0, 0, 35, 35)];
        [photo setTitleColor:UIColor.whiteColor forState:UIControlStateNormal];
        [photo setTitle:@"相册" forState:UIControlStateNormal];
        [photo addTarget:self action:@selector(selectPhoto) forControlEvents:UIControlEventTouchUpInside];
        [navBar setRightItem:photo];
        [navBar addSubview: photo];
        navBar.backButtonTitle = @"返回";
        
        _navBar = navBar;
