IOS开发 分栏控制器高级

本节学习内容：

1.分栏控件器的代理使用

2.分校控制器的协义方法

3.分栏控制器的高级使用

分栏控制器高级协义函数

willBeginCustomizingViewcontrollers:即将显示编辑方法

willEndCustomizingViewControllers:妈将结束编辑方法

didEndCustonmizingViewControllers:已经结束编辑方法

didSelectViewController:选中控制器切换方法

---

创建6个视图控器，分别为VCFirst,VCSecond,VCThird,VCFour,VCFive,VCSix都继承于UIViewController

【AppDelegate.h】

#import<UIKit/UIKit.h>

@interface

//添加UITabBarController代理  UITabBarControllerDelegate

AppDelegate:UIResponder<UIApplicationDelegate,UITabBarControllerDelegate>

@property(strong,nonatomic)UIWindow *window;

@end

【AppDelegate.m】

#import "AppDelegate.h"

#import"VCFirst.h"

#import"VCSecond.h"

#import"VCThird.h"

#import"VCFour.h"

#import"VCFive.h"

#import"VCSix.h"

@interface AppDelegate()

@end
