![enter image description here](https://img.shields.io/badge/Objective--C-compatible-orange.svg)[本Demo](https://github.com/ChenYilong/CYLTabBarControllerDemoForWeib) 使用
[CYLTabBarController](https://github.com/ChenYilong/CYLTabBarController)
实现了微博Tabbar框架,效果如下

能实现低耦合的实现 TabBarController。使用[CYLTabBarController](https://github.com/ChenYilong/CYLTabBarController)
四步完成主流App框架搭建:## 第一步:使用cocoaPods导入CYLTabBarController
在 `Podfile` 中如下导入:
```Objective-C
pod 'CYLTabBarController'
```然后使用 `cocoaPods` 进行安装:
建议使用如下方式:
```Objective-C
# 不升级CocoaPods的spec仓库
pod update --verbose
```## 第二步:设置CYLTabBarController的两个数组:控制器数组和TabBar属性数组
```Objective-C
- (void)setupViewControllers {
CYLHomeViewController *firstViewController = [[CYLHomeViewController alloc] init];
UIViewController *firstNavigationController = [[UINavigationController alloc]
initWithRootViewController:firstViewController];
CYLSameFityViewController *secondViewController = [[CYLSameFityViewController alloc] init];
UIViewController *secondNavigationController = [[UINavigationController alloc]
initWithRootViewController:secondViewController];
CYLTabBarController *tabBarController = [[CYLTabBarController alloc] init];
[self customizeTabBarForController:tabBarController];
[tabBarController setViewControllers:@[
firstNavigationController,
secondNavigationController,
]];
self.tabBarController = tabBarController;
}/*
*
在`-setViewControllers:`之前设置TabBar的属性,
*
*/
- (void)customizeTabBarForController:(CYLTabBarController *)tabBarController {
NSDictionary *dict1 = @{
CYLTabBarItemTitle : @"首页",
CYLTabBarItemImage : @"home_normal",
CYLTabBarItemSelectedImage : @"home_highlight",
};
NSDictionary *dict2 = @{
CYLTabBarItemTitle : @"同城",
CYLTabBarItemImage : @"mycity_normal",
CYLTabBarItemSelectedImage : @"mycity_highlight",
};NSArray *tabBarItemsAttributes = @[ dict1, dict2 ];
tabBarController.tabBarItemsAttributes = tabBarItemsAttributes;
}
```## 第三步:将CYLTabBarController设置为window的RootViewController
```Objective-C
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
/* *省略部分: * */
[self.window setRootViewController:self.tabBarController];
/* *省略部分: * */
return YES;
}
```## 第四步:创建自定义的形状不规则加号按钮
创建一个继承于 CYLPlusButton 的类,要求和步骤:
1. 实现 `CYLPlusButtonSubclassing` 协议
2. 子类将自身类型进行注册,一般可在 `application` 的 `applicationDelegate` 方法里面调用 `[YourClass registerSubClass]` 或者在子类的 `+load` 方法中调用:
```Objective-C
+(void)load {
[super registerSubclass];
}
```协议提供了两个可选方法:
```Objective-C
+ (NSUInteger)indexOfPlusButtonInTabBar;
+ (CGFloat)multiplerInCenterY;
```作用分别是:
```Objective-C
+ (NSUInteger)indexOfPlusButtonInTabBar;
```
用来自定义加号按钮的位置,如果不实现默认居中,但是如果 `tabbar` 的个数是奇数则必须实现该方法,否则 `CYLTabBarController` 会抛出 `exception` 来进行提示。```Objective-C
+ (CGFloat)multiplerInCenterY;
```该方法是为了调整自定义按钮中心点Y轴方向的位置,建议在按钮超出了 `tabbar` 的边界时实现该方法。返回值是自定义按钮中心点Y轴方向的坐标除以 `tabbar` 的高度,如果不实现,会自动进行比对,预设一个较为合适的位置,如果实现了该方法,预设的逻辑将失效。
详见Demo中的 `CYLPlusButtonSubclass` 类的实现。
## 补充说明
如果想更进一步的自定义 `TabBar` 样式可在 `-application:didFinishLaunchingWithOptions:` 方法中设置```Objective-C
/**
* tabBarItem 的选中和不选中文字属性、背景图片
*/
- (void)customizeInterface {
// 普通状态下的文字属性
NSMutableDictionary *normalAttrs = [NSMutableDictionary dictionary];
normalAttrs[NSForegroundColorAttributeName] = [UIColor grayColor];
// 选中状态下的文字属性
NSMutableDictionary *selectedAttrs = [NSMutableDictionary dictionary];
selectedAttrs[NSForegroundColorAttributeName] = [UIColor darkGrayColor];
// 设置文字属性
UITabBarItem *tabBar = [UITabBarItem appearance];
[tabBar setTitleTextAttributes:normalAttrs forState:UIControlStateNormal];
[tabBar setTitleTextAttributes:normalAttrs forState:UIControlStateHighlighted];
UITabBar *tabBarAppearance = [UITabBar appearance];
[tabBarAppearance setBackgroundImage:[UIImage imageNamed:@"tabbar_background"]];
}- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
/* *省略部分: * */
[self.window makeKeyAndVisible];
[self customizeInterface];
return YES;
}
