UINavigationController（导航控制器）

添加根视图

//
//  ViewController.m
//  NavigationController
#import "ViewController.h"
#import "FirstViewController.h"

@interface ViewController ()

@end

@implementation ViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    //容器
    self.view.backgroundColor = [UIColor redColor];
    
}
- (void)touchesBegan:(NSSet<UITouch *> *)touches withEvent:(UIEvent *)event{
    
    FirstViewController *vc = [[FirstViewController alloc]init];
    UINavigationController *nc = [[UINavigationController alloc]initWithRootViewController:vc];
    [nc.navigationBar setTranslucent:NO];
    [self presentViewController:nc animated:YES completion:^{
        
    }];
    
    
}
@end

@implementation FirstViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    self.view.backgroundColor = [UIColor yellowColor];
    
    self.title = @"First";
  UIBarButtonItem *item = [[UIBarButtonItem alloc]initWithTitle:@"编辑" style:UIBarButtonSystemItemEdit target:self action:@selector(edit:)];
    
    
    UIButton *editButton = [UIButton buttonWithType:UIButtonTypeCustom];
    [editButton setTitle:@"自定义的编辑" forState:UIControlStateNormal];
    [editButton setTitleColor:[UIColor greenColor] forState:UIControlStateNormal];
    [editButton setBackgroundColor:[UIColor yellowColor]];
    [editButton addTarget:self action:@selector(edit:) forControlEvents:UIControlEventTouchUpInside];
    
    
    UIBarButtonItem *item1 = [[UIBarButtonItem alloc]initWithCustomView:editButton];
    
    self.navigationItem.rightBarButtonItem = item1;
}

- (void)edit:(UIBarButtonItem *)sender{
    SecondViewController *secondViewC = [[SecondViewController alloc]init];
    [self.navigationController pushViewController:secondViewC animated:YES];
}
@end

UITabBarController（选项卡导航器）

将UINavigationController放到UITabController中

//
//  ViewController.m
//  UITabBarController

#import "ViewController.h"
#import "FirstViewController.h"
#import "SecondViewController.h"
#import "ThirdViewController.h"

@interface ViewController ()

@end

@implementation ViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    
}

- (void)touchesBegan:(NSSet<UITouch *> *)touches withEvent:(UIEvent *)event{
    //tabbarController  最大
    //navigationControlelr
    //里面放的是viewcontroller
    FirstViewController *first = [[FirstViewController alloc]init];
    UINavigationController *nav1 = [[UINavigationController alloc]initWithRootViewController:first];
    [nav1.navigationBar setTranslucent:NO];
    nav1.title = @"First";
    
    UIImage *nav1DefImage = [UIImage imageNamed:@"home_discovergray"];
    nav1DefImage = [nav1DefImage imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];
    
    
    UIImage *nav1SelectedImage = [UIImage imageNamed:@"home_discovegreen"];
    nav1SelectedImage = [nav1SelectedImage imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];
    
    nav1.tabBarItem.image = nav1DefImage;
    nav1.tabBarItem.selectedImage = nav1SelectedImage;
    
    
    
    SecondViewController *second = [[SecondViewController alloc]init];
    UINavigationController *nav2 = [[UINavigationController alloc]initWithRootViewController:second];
    nav2.title = @"Second";
    nav2.tabBarItem.image = [UIImage imageNamed:@"home_personalgray"];
    nav2.tabBarItem.selectedImage = [UIImage imageNamed:@"home_personalgreen"];

    ThirdViewController *third = [[ThirdViewController alloc]init];
    UINavigationController *nav3 = [[UINavigationController alloc]initWithRootViewController:third];
    nav3.title = @"Third";
    nav3.tabBarItem.image = [UIImage imageNamed:@"home_studygray"];
    nav3.tabBarItem.selectedImage = [UIImage imageNamed:@"home_studygreen"];

    
    
    UITabBarController *tabBarControlelr = [[UITabBarController alloc]init];
    tabBarControlelr.viewControllers = @[nav1,nav2,nav3];
    tabBarControlelr.tabBar.translucent = NO;
    
    [[UITabBarItem appearance]setTitleTextAttributes:@{NSForegroundColorAttributeName:[UIColor lightGrayColor]} forState:UIControlStateNormal];
    
    [[UITabBarItem appearance]setTitleTextAttributes:@{NSForegroundColorAttributeName:[UIColor orangeColor]} forState:UIControlStateSelected];

    
    [self presentViewController:tabBarControlelr animated:YES completion:^{
        
    }];
   
}

页面跳转

使用presenter进行跳转

//  ViewController.m
//  页面的跳转
#import "ViewController.h"
#import "FirstViewController.h"
#import "SecondViewController.h"

@interface ViewController ()

@end

@implementation ViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    self.view.backgroundColor = [UIColor redColor];
    /*
     push与present都可以推出新的界面。
     present与dismiss对应，push和pop对应。
     present只能逐级返回，push所有视图由视图栈控制，可以返回上一级，也可以返回到根vc，其他vc。
     present一般用于不同业务界面的切换，push一般用于同一业务不同界面之间的切换
     */
    
}

- (void)touchesBegan:(NSSet<UITouch *> *)touches withEvent:(UIEvent *)event{
    
    
    FirstViewController *first = [[FirstViewController alloc]init];
    UINavigationController *nv = [[UINavigationController alloc]initWithRootViewController:first];
    
    [self presentViewController:nv animated:YES completion:^{
        
    }];
    
}
@end

使用dismiss销毁和push进行跳转

//  FirstViewController.m
//  页面的跳转
#import "FirstViewController.h"
#import "SecondViewController.h"

@interface FirstViewController ()

@end

@implementation FirstViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    self.view.backgroundColor = [UIColor yellowColor];
    self.title = @"First";
    
    UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
    [button setTitle:@"返回" forState:UIControlStateNormal];
    [button addTarget:self action:@selector(back:) forControlEvents:UIControlEventTouchUpInside];
    [self.view addSubview:button];
    button.frame = CGRectMake(0, 100, 100, 40);
    [button setBackgroundColor:[UIColor whiteColor]];
    [button setTitleColor:[UIColor blueColor] forState:UIControlStateNormal];
    
    
    UIButton *button1 = [UIButton buttonWithType:UIButtonTypeCustom];
    [button1 setTitle:@"跳转" forState:UIControlStateNormal];
    [button1 addTarget:self action:@selector(push:) forControlEvents:UIControlEventTouchUpInside];
    [self.view addSubview:button1];
    button1.frame = CGRectMake(0, 200, 100, 40);
    [button1 setBackgroundColor:[UIColor whiteColor]];
    [button1 setTitleColor:[UIColor blueColor] forState:UIControlStateNormal];
    
}

- (void)back:(UIButton *)sender{
    [self dismissViewControllerAnimated:YES completion:^{
        
    }];
}


- (void)push:(UIButton *)sender{
    
    SecondViewController *second = [[SecondViewController alloc]init];
    
    [self.navigationController pushViewController:second animated:YES];
    
}

@end

使用pop返回上一页

//  SecondViewController.m
//  页面的跳转

#import "SecondViewController.h"
#import "ThirdViewController.h"

@interface SecondViewController ()

@end

@implementation SecondViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    self.view.backgroundColor = [UIColor greenColor];
    self.title = @"Second";
    UIButton *button1 = [UIButton buttonWithType:UIButtonTypeCustom];
    [button1 setTitle:@"返回" forState:UIControlStateNormal];
    [button1 addTarget:self action:@selector(back:) forControlEvents:UIControlEventTouchUpInside];
    [self.view addSubview:button1];
    button1.frame = CGRectMake(0, 200, 100, 40);
    [button1 setBackgroundColor:[UIColor whiteColor]];
    [button1 setTitleColor:[UIColor blueColor] forState:UIControlStateNormal];
    
    
    UIButton *button2 = [UIButton buttonWithType:UIButtonTypeCustom];
    [button2 setTitle:@"跳转" forState:UIControlStateNormal];
    [button2 addTarget:self action:@selector(push:) forControlEvents:UIControlEventTouchUpInside];
    [self.view addSubview:button2];
    button2.frame = CGRectMake(0, 100, 100, 40);
    [button2 setBackgroundColor:[UIColor whiteColor]];
    [button2 setTitleColor:[UIColor blueColor] forState:UIControlStateNormal];

}
- (void)back:(UIButton *)sender{
//    [self.navigationController popViewControllerAnimated:YES];
    [self.navigationController popToRootViewControllerAnimated:YES];
}

- (void)push:(UIButton *)sender{
    ThirdViewController *third = [[ThirdViewController alloc]init];
    [self.navigationController pushViewController:third animated:YES];
}
