StoryBoard学习1 tabbar实现

1、建立基于 Tabbed Application  项目: (压缩包中 1.jpg)


2、打开 Main.storyboard ,拖2个NavigationController到 storyboad中,并加在tabbarController中:  (压缩包中 2.jpg)

3、系统的图标太难看了,并且!!点击只能是系统默认的蓝色,找了好久,只能用代码搞定它了,在四个tabbarController中的第一个显示的tabbarController的viewDidLoad实现如下代码: (压缩包中 3.jpg)

static bool isReseted = false;

- (void)resetTabarItemOnlyOnce{

    if (isReseted == false) {

        UITabBarController *tabBarVC = self.tabBarController;

        NSArray *imageArr = @[@"Home",@"Product",@"Cart",@"Self"];

        for (int i=0; i<imageArr.count; i++) {

            UITabBarItem *tabBarItem = [tabBarVC.tabBar.items objectAtIndex:i];

            tabBarItem.selectedImage = [[UIImage imageNamed:STRING_FORMAT(@"%@-on",imageArr[i])] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];

            tabBarItem.image = [UIImage imageNamed:STRING_FORMAT(@"%@-off",imageArr[i])];

        }

        isReseted = true;

        NSLog(@"<=== 默认tabbar图片 ===>");

    }else{

        NSLog(@"<=== 默认tabbar图片只会执行一次 ===>");

    }

}


字体也一样:

 NSDictionary *textDic = [NSDictionary dictionaryWithObjectsAndKeys:NavBarColor,NSForegroundColorAttributeName,nil];

[tabBarItem setTitleTextAttributes:textDic forState:UIControlStateSelected];
