先在AppDelegate类里面添加窗口和导航控制器
#import "AppDelegate.h"！！！切记：引入别的视图的.h头文件#import "ViewController.h"@interface AppDelegate ()@end@implementation AppDelegate- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { //创建Window self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]]; self.window.backgroundColor = [UIColor redColor]; //让当前的Window成为主窗口 [self.window makeKeyAndVisible]; //设置Window的根视图 ViewController *a = [[ViewController alloc]init]; //1.创建一个导航控制器 UINavigationController *nav=[[UINavigationController alloc]initWithRootViewController:a]; //2.设置导航控制器为window的根视图 self.window.rootViewController=nav; //给导航控制器着色 nav.navigationBar.barTintColor = [UIColor yellowColor]; //给导航栏添加图片 [nav.navigationBar setBackgroundImage:[UIImage imageNamed:@"qidong.jpg"] forBarMetrics:UIBarMetricsDefault]; //设置导航的透明度 [nav.navigationBar setBarStyle:UIBarStyleBlack]; nav.navigationBar.translucent = YES; return YES;}
接着在第一个视图里面设置一个Button，点击跳到下一个界面，里面有导航栏的各种设置
#import "ViewController.h"！！！切记：引入别的视图的.h头文件#import "TwoViewController.h"@interface ViewController ()@end@implementation ViewController- (void)viewDidLoad { [super viewDidLoad]; //新建一个按钮 UIButton *myButtonOne = [[UIButton alloc]initWithFrame:CGRectMake(100, 100, 100, 100)]; myButtonOne.backgroundColor = [UIColor blueColor]; [myButtonOne addTarget:self action:@selector(haha:) forControlEvents:UIControlEventTouchUpInside]; [self.view addSubview:myButtonOne]; //设置当前界面的颜色 self.view.backgroundColor = [UIColor orangeColor]; //设置导航栏的标题// self.navigationItem.title = @"微信"; //自定义标题（也就是导航栏里面中间的标题可以点击，所以是个Button） UIButton *titleButton = [UIButton buttonWithType:UIButtonTypeCustom]; //设置标题的大小 titleButton.frame = CGRectMake(0, 0, 100, 40); //设置标题文字的内容 [titleButton setTitle:@"我可以点击" forState:UIControlStateNormal]; //设置标题文字的颜色 [titleButton setTitleColor:[UIColor yellowColor] forState:UIControlStateNormal]; //设置标题文字的字体和大小 titleButton.titleLabel.font = [UIFont systemFontOfSize:20]; //给标题文字（其实是个Button）添加触动方法 [titleButton addTarget:self action:@selector(xixi:) forControlEvents:UIControlEventTouchUpInside]; //设置标题文字的底色 [titleButton setBackgroundColor:[UIColor redColor]]; //将标题文字（其实是个Button）赋给导航栏的标题 self.navigationItem.titleView =titleButton; //设置左右两边的按钮 //设置左边的按钮// UIBarButtonItem *left = [[UIBarButtonItem alloc]initWithTitle:@"左边" style:UIBarButtonItemStylePlain target:self action:@selector(selfhaha:)];// self.navigationItem.leftBarButtonItem = left; //设置右边的按钮 UIBarButtonItem *right = [[UIBarButtonItem alloc]initWithTitle:@"右边" style:UIBarButtonItemStylePlain target:self action:@selector(righthaha:)]; //设置右边第二个按钮 UIBarButtonItem *rightTwo = [[UIBarButtonItem alloc]initWithTitle:@"右二" style:UIBarButtonItemStylePlain target:self action:@selector(rightTwohaha:)]; //设置右边第三个按钮 UIBarButtonItem *rightThree = [[UIBarButtonItem alloc]initWithTitle:@"右三" style:UIBarButtonItemStylePlain target:self action:@selector(rightThreehaha:)]; //如果一次有很多按钮的话，要用数组来设置 self.navigationItem.rightBarButtonItems = @[right,rightTwo,rightThree]; //将左边的按钮换成图片 UIBarButtonItem *leftImage = [[UIBarButtonItem alloc]initWithImage:[UIImage imageNamed:@"666"] style:UIBarButtonItemStylePlain target:self action:@selector(leftImagehaha:)]; self.navigationItem.leftBarButtonItem = leftImage; }//按钮的方法-(void)haha:(id)a{ //push到下一个界面 TwoViewController *x = [[TwoViewController alloc]init]; [self.navigationController pushViewController:x animated:YES]; }-(void)xixi:(id)a{ NSLog(@"我是中间的标题，我被点击了");}-(void)selfhaha:(id)a{ NSLog(@"我是左边");}-(void)righthaha:(id)a{ NSLog(@"我是右边");}-(void)rightTwohaha:(id)a{ NSLog(@"我是右二");}-(void)rightThreehaha:(id)a{ NSLog(@"我是右三");}-(void)leftImagehaha:(id)a{ NSLog(@"我是左边的图片");}
接着在第二个视图里面设置一个Button，点击跳到下一个界面
#import "TwoViewController.h"//！！！切记：引入别的视图的.h头文件#import "ThreeViewController.h"@interface TwoViewController ()@end@implementation TwoViewController- (void)viewDidLoad { [super viewDidLoad]; //设置界面颜色 self.view.backgroundColor = [UIColor purpleColor]; //新建一个按钮 UIButton *myButtonOne = [[UIButton alloc]initWithFrame:CGRectMake(100, 100, 100, 100)]; myButtonOne.backgroundColor = [UIColor blueColor]; [myButtonOne addTarget:self action:@selector(haha2:) forControlEvents:UIControlEventTouchUpInside]; [self.view addSubview:myButtonOne]; }//按钮的方法-(void)haha2:(id)a{ //跳到指定的页面 ThreeViewController *x = [[ThreeViewController alloc]init]; [self.navigationController pushViewController:x animated:YES]; }
接着在第三个视图里面设置一个Button，点击跳回上一个页面、或者任意视图，或者直接返回主视图
#import "ThreeViewController.h"//！！！切记：引入别的视图的.h头文件#import "ViewController.h"@interface ThreeViewController ()@end@implementation ThreeViewController- (void)viewDidLoad { [super viewDidLoad]; //设置界面的颜色 self.view.backgroundColor = [UIColor greenColor]; //新建一个按钮 UIButton *myButtonOne = [[UIButton alloc]initWithFrame:CGRectMake(100, 100, 100, 100)]; myButtonOne.backgroundColor = [UIColor blueColor]; [myButtonOne addTarget:self action:@selector(haha3:) forControlEvents:UIControlEventTouchUpInside]; [self.view addSubview:myButtonOne]; }//按钮的方法-(void)haha3:(id)a{ //！！！切记：引入别的视图的.h头文件 //跳到最根的视图 [self.navigationController popToRootViewControllerAnimated:YES]; //返回上一级视图 [self.navigationController popViewControllerAnimated:YES]; //跳到任意指定视图 for (UIViewController *temp in self.navigationController.viewControllers) { if ([temp isKindOfClass:[ViewController class]]) { [self.navigationController popToViewController:temp animated:YES]; } } }
直接设置导航栏上的标题字体和颜色
//直接设置导航栏上的标题字体和颜色 [self.navigationController.navigationBar setTitleTextAttributes:@{NSFontAttributeName:[UIFont systemFontOfSize:18], NSForegroundColorAttributeName:[UIColor blackColor]}];
在当前页面隐藏导航栏，并设置透明度（从导航栏下面作为 Y轴 的0起点）
//每次进来都会加载一次- (void)viewWillAppear:(BOOL)animated{ //取消隐藏导航栏(如果要隐藏，改为yes就行了) self.navigationController.navigationBarHidden = NO; //设置导航栏透明度 self.navigationController.navigationBar.translucent = NO; }
去掉push到的视图中 自带的返回箭头< 右边的文字，并改变箭头 < 的颜色
//去掉子视图（push到的视图）中的返回箭头 < 右边的文字 UIBarButtonItem *item = [[UIBarButtonItem alloc] initWithTitle:@"" style:UIBarButtonItemStylePlain target:nil action:nil]; self.navigationItem.backBarButtonItem = item; //改变上面箭头的颜色（会全部都改变） [[UINavigationBar appearance] setTintColor:[UIColor blackColor]]; //左边返回箭头颜色（改变左边返回箭头颜色） self.navigationController.navigationBar.tintColor = [UIColor whiteColor];
第二种方法：
//去掉PUSH后的back文字(第二种方法) [[UIBarButtonItem appearance] setBackButtonTitlePositionAdjustment:UIOffsetMake(0, -60) forBarMetrics:UIBarMetricsDefault];
清除滑动时 cell 中间的缝隙
//清除滑动时中间的缝隙 choiceTableView.separatorColor=[UIColor clearColor];
