大家好,又见面了,我是全栈君,今天给大家准备了Idea注册码。
<span style="font-family: Arial, Helvetica, sans-serif;"></span><pre name="code" class="objc">- (void)initTabBar { // 初始化主页 HomePageViewController *homePage = [[HomePageViewController alloc]init]; UINavigationController *homePageNav = [[UINavigationController alloc]initWithRootViewController:homePage]; // 推断是否存在用户存储的城市 NSUserDefaults *userDefault = [NSUserDefaults standardUserDefaults]; if (![userDefault objectForKey:@"cityDic"]) { CitySelectionViewController *citySelection = [[CitySelectionViewController alloc]init]; [homePageNav pushViewController:citySelection animated:YES]; } // 设置主页-TabBar UITabBarItem *itemHomePage= [[UITabBarItem alloc] initWithTitle:@"首页" image:[UIImage imageWithImage:[UIImage imageNamed:@"1-1.png"] scaledToSize:CGSizeMake(25, 25)] tag:0]; [itemHomePage setFinishedSelectedImage:[UIImage imageWithImage:[UIImage imageNamed:@"1-1.jpg"] scaledToSize:CGSizeMake(25, 25)] withFinishedUnselectedImage:[UIImage imageWithImage:[UIImage imageNamed:@"1-2.jpg"] scaledToSize:CGSizeMake(25, 25)]]; homePageNav.tabBarItem=itemHomePage; [itemHomePage setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:NAVBACKGROUNDCOLOR,UITextAttributeTextColor, nil] forState:UIControlStateSelected]; if (SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO([NSString stringWithFormat:@"7.0"])) { [homePageNav.navigationBar setBarTintColor:NAVBACKGROUNDCOLOR]; }else { [homePageNav.navigationBar setTintColor:NAVBACKGROUNDCOLOR]; } homePageNav.navigationBar.translucent = NO; // 初始化我的购物车 ShoppingCartViewController *shoppingCart = [[ShoppingCartViewController alloc]init]; UINavigationController *shoppingCartNav = [[UINavigationController alloc]initWithRootViewController:shoppingCart]; // 设置购物车-TabBar UITabBarItem *itemShoppingCart= [[UITabBarItem alloc] initWithTitle:@"我的购物车" image:[UIImage imageWithImage:[UIImage imageNamed:@"1-1.png"] scaledToSize:CGSizeMake(25, 25)] tag:0]; [itemShoppingCart setFinishedSelectedImage:[UIImage imageWithImage:[UIImage imageNamed:@"1-1.jpg"] scaledToSize:CGSizeMake(25, 25)] withFinishedUnselectedImage:[UIImage imageWithImage:[UIImage imageNamed:@"1-2.jpg"] scaledToSize:CGSizeMake(25, 25)]]; shoppingCartNav.tabBarItem=itemShoppingCart; [itemShoppingCart setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:NAVBACKGROUNDCOLOR,UITextAttributeTextColor, nil] forState:UIControlStateSelected]; if (SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO([NSString stringWithFormat:@"7.0"])) { [shoppingCartNav.navigationBar setBarTintColor:NAVBACKGROUNDCOLOR]; }else { [shoppingCartNav.navigationBar setTintColor:NAVBACKGROUNDCOLOR]; } shoppingCartNav.navigationBar.translucent = NO; // 初始化我的汇众 IndividualCenterViewController *individualCenter = [[IndividualCenterViewController alloc]init]; UINavigationController *individualCenterNav = [[UINavigationController alloc]initWithRootViewController:individualCenter]; // 设置汇众-TabBar UITabBarItem *itemindividualCenter= [[UITabBarItem alloc] initWithTitle:@"我的幸福家" image:[UIImage imageWithImage:[UIImage imageNamed:@"1-1.png"] scaledToSize:CGSizeMake(25, 25)] tag:0]; [itemindividualCenter setFinishedSelectedImage:[UIImage imageWithImage:[UIImage imageNamed:@"1-1.jpg"] scaledToSize:CGSizeMake(25, 25)] withFinishedUnselectedImage:[UIImage imageWithImage:[UIImage imageNamed:@"1-2.jpg"] scaledToSize:CGSizeMake(25, 25)]]; individualCenterNav.tabBarItem=itemindividualCenter; [itemindividualCenter setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:NAVBACKGROUNDCOLOR,UITextAttributeTextColor, nil] forState:UIControlStateSelected]; if (SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO([NSString stringWithFormat:@"7.0"])) { [individualCenterNav.navigationBar setBarTintColor:NAVBACKGROUNDCOLOR]; }else { [individualCenterNav.navigationBar setTintColor:NAVBACKGROUNDCOLOR]; } individualCenterNav.navigationBar.translucent = NO; self.tabBar = [[UITabBarController alloc] init]; [[UITabBar appearance] setBackgroundImage:[UIImage setBackgroundImageByColor:COLOR(255, 255, 255, 1) withFrame:RectWithPara(0, 0, SCREEN_WIDTH, 44)]]; // 设置UITabBar背景图片 [[UITabBar appearance] setSelectionIndicatorImage: [UIImage imageWithTint:COLOR(235, 235, 235, 1)]]; self.tabBar.viewControllers = [NSArray arrayWithObjects:homePageNav,shoppingCartNav,individualCenterNav, nil]; }
<span style="font-family: Arial, Helvetica, sans-serif;">在程序启动时设置根控制器为 tabbar,例如以下</span>
– (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
[self initTabBar];
self.window.rootViewController = self.tabBar;
self.window.backgroundColor = [UIColor whiteColor];
[self.window makeKeyAndVisible];
return YES;
}
