Appdelegate中的使用：

    tabbarVC.setupItemTitles(@[@"首页",@"发现",@"我的"]).setUpUnSelectImages(@[@"shouye",@"faxian",@"geren"]).setUpSelectImages(@[@"shouye",@"faxian",@"geren"]);
    self.window.rootViewController = tabbarVC;

ViewControler中单航条的设置：

    self.setUpNaviTitle(@"首页").setUpTitleFont([UIFont systemFontOfSize:17]).setUpTitleColcor([UIColor whiteColor]);
    [self rightImageItem:@"shouye" action:^{
        
    }];
