iOS 第9課 導航視圖 NavigationView

導航視圖和android 中的viewpager類似

//導覽列相關的是navigationItem，控制器相關的是navigationController

0: 首先還是通過純的代碼來實現

0：刪除3個檔案ViewController.h，ViewController.m，Main.storyboard

1：修改點擊左邊的藍色按鈕，然後選擇general－》developer info－》main interface ，將這個main interface 晴空

1: 修改appdeleget

2: 建立三個控制器，

2.1: 第一個控制器：

////  FirstViewController.m//  NineNavigationDemo////  Created by 千雅爸爸 on 16/10/15.//  Copyright © 2016年 kodulf. All rights reserved.//#import "FirstViewController.h"#import "SecondViewController.h"@interface FirstViewController ()@end@implementation FirstViewController- (void)viewDidLoad {    //導覽列的座標是（0，20，寬度，44）；        //導覽列相關的是navigationItem，控制器相關的是navigationController    [super viewDidLoad];    [self setTitle:@"第一頁"];    [self.view setBackgroundColor:[UIColor greenColor]];//    UIBarButtonItem *item =[[UIBarButtonItem alloc]initWithBarButtonSystemItem:UIBarButtonSystemItemAdd target:self action:NULL];    //設定導航的item    self.navigationItem.rightBarButtonItem = item;        //自訂view作為導航的菜單    UIButton *itemButton = [UIButton buttonWithType:UIButtonTypeCustom];    [itemButton setTitle:@"UIButton" forState:UIControlStateNormal];    [itemButton setTitleColor:[UIColor greenColor] forState:UIControlStateHighlighted];    [itemButton setFrame:CGRectMake(0,0,100,100)];        UIBarButtonItem *item2 = [[UIBarButtonItem alloc]initWithCustomView:itemButton];        //設定多個button    self.navigationItem.leftBarButtonItems = @[item,item2];        //設定導航藍上面的顏色    self.navigationController.navigationBar.backgroundColor = [UIColor blueColor];    [self.navigationController.navigationBar setBackgroundImage:[UIImage imageNamed:@"background"] forBarMetrics:UIBarMetricsCompact];//後面的是圖片的渲染的樣式的。    //UIBarMetricsDefault預設的,背景的圖片和顏色是不能重複的，像這裡圖片會覆蓋顏色的    //UIBarMetricsCompac 會使用圖片的顏色            //注意了，這裡的尺寸裡面的位置，    UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];    [button setTitle:@"Push" forState:UIControlStateNormal];    [button setTitleColor:[UIColor redColor] forState:UIControlStateHighlighted];    [button setBackgroundColor:[UIColor blackColor]];    [button setFrame:CGRectMake(100,80,100,100)];    [button addTarget:self action:@selector(pushController) forControlEvents:UIControlEventTouchUpInside];//當在內部點擊的時候觸發    [self.view addSubview:button];        //導覽列控制器在控制多個視圖控制的時候的跳轉        // Do any additional setup after loading the view.}//相當於入戰的操作-(void) pushController{    NSLog(@"點擊了first");    [self.navigationController pushViewController:[[SecondViewController alloc]init] animated:YES];}- (void)didReceiveMemoryWarning {    [super didReceiveMemoryWarning];    // Dispose of any resources that can be recreated.}/*#pragma mark - Navigation// In a storyboard-based application, you will often want to do a little preparation before navigation- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {    // Get the new view controller using [segue destinationViewController].    // Pass the selected object to the new view controller.}*/@end

2.2 第二個控制器

////  SecondViewController.m//  NineNavigationDemo////  Created by 千雅爸爸 on 16/10/15.//  Copyright © 2016年 kodulf. All rights reserved.//#import "SecondViewController.h"#import "FirstViewController.h"#import "ThirdViewController.h"@interface SecondViewController ()@end@implementation SecondViewController- (void)viewDidLoad {    //導覽列相關的是navigationItem，控制器相關的是navigationController        [super viewDidLoad];    //預設的切換的時候是有一些卡頓的。    [self.view setBackgroundColor:[UIColor yellowColor]];    [self setTitle:@"第二頁"];    //多個子控制器對象是公用一個導航條的        //添加統一的返回按鈕,簡單的就是一個子    UIBarButtonItem *leftItem =[[UIBarButtonItem alloc] initWithTitle:@"回退" style:UIBarButtonItemStylePlain target:self action:@selector(popController)];    self.navigationItem.leftBarButtonItem = leftItem;            UIBarButtonItem *rightItem =[[UIBarButtonItem alloc]initWithTitle:@"下一個" style:UIBarButtonItemStylePlain target:self action:@selector(pushController)];        // Do any additional setup after loading the view.        self.navigationItem.rightBarButtonItem = rightItem;    //公用一套導航條的    [self.navigationController.navigationBar setTitleTextAttributes:@{NSForegroundColorAttributeName:[UIColor whiteColor]}];}-(void )popController{    [self.navigationController popViewControllerAnimated:YES];}-(void)pushController{    [self.navigationController pushViewController:[[ThirdViewController alloc]init] animated:YES];}- (void)didReceiveMemoryWarning {    [super didReceiveMemoryWarning];    // Dispose of any resources that can be recreated.}/*#pragma mark - Navigation// In a storyboard-based application, you will often want to do a little preparation before navigation- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {    // Get the new view controller using [segue destinationViewController].    // Pass the selected object to the new view controller.}*/@end

2.3: 第三個控制器

////  ThirdViewController.m//  NineNavigationDemo////  Created by 千雅爸爸 on 16/10/15.//  Copyright © 2016年 kodulf.
