IOS开发（7）之UINavigationController导航

本文主要是介绍IOS开发（7）之UINavigationController导航，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

1 前言

UINavigationController会让App从一个试图控制器切换到另一个，在开发中十分常见，今天我们来学习一下这个控件。

2 UINavigation简介

delegate代码

.h文件：

#import <UIKit/UIKit.h>
#import "ZYRootViewController.h"@interface ZYAppDelegate : UIResponder <UIApplicationDelegate>@property (strong, nonatomic) UIWindow *window;
@property(nonatomic,strong) ZYRootViewController *zYRootViewController;
@property(nonatomic,strong) UINavigationController *navigationController;@end

.m文件：

@synthesize navigationController;
@synthesize zYRootViewController;- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];// Override point for customization after application launch.self.window.backgroundColor = [UIColor whiteColor];[self.window makeKeyAndVisible];self.zYRootViewController = [[ZYRootViewController alloc] initWithNibName:nil bundle:nil];//实例化导航栏self.navigationController = [[UINavigationController alloc] initWithRootViewController:self.zYRootViewController];//向当前视图添加导航栏self.window.rootViewController = self.navigationController;
//    [self.window addSubview:self.navigationController.view];return YES;
}

ZYRootViewController代码

.m文件：

- (void)viewDidLoad
{[super viewDidLoad];// Do any additional setup after loading the view.self.title = @"First";//设置标题[self performSelector:@selector(pushSecondController) withObject:nil afterDelay:3.0f];//3秒后调用自身pushSecondController方法
}-(void)pushSecondController{ZYSecondViewController *zYSecondViewController = [[ZYSecondViewController alloc] initWithNibName:nil bundle:nil];[self.navigationController pushViewController:zYSecondViewController animated:YES];//向导航栏堆栈推入zYSecondViewController视图
}

ZYSecondViewController代码

.m文件：

- (void)viewDidLoad
{[super viewDidLoad];self.title = @"Second";// Do any additional setup after loading the view.[self performSelector:@selector(goBack) withObject:nil afterDelay:3.0f];//3秒后调用自身goBack方法
}-(void)goBack{[self.navigationController popViewControllerAnimated:YES];//将自身视图弹出导航栏堆栈
}

运行结果：
