本文写的是关于基础的模板样式，TabBar上有四个item，然后绑定NavigationController，在具体的实现过程中可能会有不同的样式和需求，所以需要看情况更改。
首先封装NavigationController
新建一个HHBaseNavigationController，继承自UINavigationController
然后在其.m文件中设置
+ (void)initialize {
// 设置导航items数据主题
[self setupNavigationItemsTheme];
// 设置导航栏主题
[self setupNavigationBarTheme];
}
#pragma mark - 设置导航items数据主题
+ (void)setupNavigationItemsTheme {
UIBarButtonItem *barButtonItem = [UIBarButtonItem appearance];
// 设置字体颜色
[barButtonItem setTitleTextAttributes:@{NSForegroundColorAttributeName : [UIColor blackColor], NSFontAttributeName : [UIFont systemFontOfSize:14]} forState:UIControlStateNormal];
[barButtonItem setTitleTextAttributes:@{NSForegroundColorAttributeName : [UIColor redColor]} forState:UIControlStateHighlighted];
[barButtonItem setTitleTextAttributes:@{NSForegroundColorAttributeName : [UIColor lightGrayColor]} forState:UIControlStateDisabled];
}
#pragma mark - 设置导航栏主题
+ (void)setupNavigationBarTheme {
UINavigationBar * navBar = [UINavigationBar appearance];
// 设置导航栏title属性
[navBar setTitleTextAttributes:@{NSForegroundColorAttributeName : [UIColor blackColor]}];
// 设置导航栏颜色
[navBar setBarTintColor:[UIColor cyanColor]];
UIImage *image = [UIImage imageNamed:@"nav_64"];
[navBar setBackgroundImage:image forBarMetrics:UIBarMetricsDefault];
}
#pragma mark - 拦截所有push方法
- (void)pushViewController:(UIViewController *)viewController animated:(BOOL)animated {
if (self.viewControllers.count > 0) {
// 如果navigationController的字控制器个数大于两个就隐藏
viewController.hidesBottomBarWhenPushed = YES;
viewController.navigationItem.leftBarButtonItem = [[UIBarButtonItem alloc] initWithTitle:@"返回" style:UIBarButtonItemStyleDone target:self action:@selector(back)];
}
[super pushViewController:viewController animated:YES];
}
#pragma mark - 拦截所有pop方法
- (void)back {
[super popViewControllerAnimated:YES];
//这里就可以自行修改返回按钮的各种属性等
}
再封装一个TabBarController
新建一个HHTabBarViewController，继承自UITabBarController
然后在其.m文件中设置
//首先就是包含NavigationController的头文件
#import "HHBaseNavigationController.h"
#import "XBSViewController.h" //这是我要绑定的几个主页面
#import "SearchViewController.h" //这是我要绑定的几个主页面
#import "HomeViewController.h"//这是我要绑定的几个主页面
#import "MeViewController.h"// 这是我要绑定的几个主页面
+ (void)initialize {
// 设置UITabBarItem主题
[self setupTabBarItemTheme];
// 设置UITabBar主题
[self setupTabBarTheme];
}
+ (void)setupTabBarItemTheme {
UITabBarItem *tabBarItem = [UITabBarItem appearance];
/**设置文字属性**/
// 普通状态
[tabBarItem setTitleTextAttributes:@{NSFontAttributeName : [UIFont systemFontOfSize:12.0f], NSForegroundColorAttributeName : [UIColor grayColor]} forState:UIControlStateNormal];
// 选中状态
[tabBarItem setTitleTextAttributes:@{NSFontAttributeName : [UIFont systemFontOfSize:12.0f],NSForegroundColorAttributeName : [UIColor orangeColor]} forState:UIControlStateSelected];
// 高亮状态
// [tabBarItem setTitleTextAttributes:@{} forState:UIControlStateHighlighted];
// 不可用状态(disable)
// [tabBarItem setTitleTextAttributes:@{} forState:UIControlStateDisabled];
}
+ (void)setupTabBarTheme {
// UITabBar *tabBar = [UITabBar appearance];
}
- (void)viewDidLoad {
[super viewDidLoad];
// 添加所有子控制器
[self addAllViewControllers];
// 创建自定义TabBar
[self addCustomTabBar];
}
#pragma mark - 添加所有子控制器
- (void)addAllViewControllers {
//将需要绑定的页面添加进来
XBSViewController *XBSVc = [XBSViewController new];
[self addOneChildVc:XBSVc title:@"幼儿园" imageName:@"app_icon02" selectedImageName:@"app_icon02_b"];
SearchViewController *searchVc = [SearchViewController new];
[self addOneChildVc:searchVc title:@"家庭教育" imageName:@"app_icon03" selectedImageName:@"app_icon03_b"];
HomeViewController *homeVc = [HomeViewController new];
[self addOneChildVc:homeVc title:@"发现" imageName:@"app_icon04" selectedImageName:@"app_icon04_b"];
MeViewController *meVc = [MeViewController new];
[self addOneChildVc:meVc title:@"我" imageName:@"app_icon01" selectedImageName:@"app_icon01_b"];
}
#pragma mark - 添加一个子控制器
- (void)addOneChildVc:(UIViewController *)childVc title:(NSString *)title imageName:(NSString *)imageName selectedImageName:(NSString *)seletedImageName {
childVc.tabBarItem.title = title;
childVc.tabBarItem.image = [UIImage imageNamed:imageName];
childVc.tabBarItem.selectedImage = [[UIImage imageNamed:seletedImageName] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];
// [[UITabBarItem appearance] setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:[UIColor grayColor], NSForegroundColorAttributeName, [UIFont fontWithName:title size:12.0f],NSFontAttributeName,nil] forState:UIControlStateNormal];
// [[UITabBarItem appearance] setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:[UIColor orangeColor], NSForegroundColorAttributeName, [UIFont fontWithName:title size:12.0f],NSFontAttributeName,nil] forState:UIControlStateSelected];
//将NavigationController给包含进来。
[self addChildViewController:[[HHBaseNavigationController alloc] initWithRootViewController:childVc]];
}
#pragma mark - 自定义TabBar
- (void)addCustomTabBar {
// GLTabBar *tabBar = [GLTabBar new];
// tabBar.tabBarDelegate = self;
// [self setValue:tabBar forKeyPath:@"tabBar"];
}
最后就是在AppDelegate.m里边设置开始页面了
//包含刚才封装的两个头文件
#import "HHBaseNavigationViewController.h"
#import "HHTabBarViewController.h"
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
// Override point for customization after application launch.
_window.backgroundColor = [UIColor whiteColor];
// _window = [[UIWindow alloc]initWithFrame:[UIScreen mainScreen].bounds];
_window.rootViewController = HHTabBarViewController.new;
[_window makeKeyAndVisible];
//设置状态栏
// [[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleLightContent];
return YES;
}
以上就完成了最基本的设置
通过看这次简单的封装，我们能找到封装的思路，然后模仿着去做一些改动。
不过想要达到各种效果，就需要去进行一些符合自己要求的更改封装了。
