IOS 中的页面跳转（navigaitonController）+带自动返回

页面1 跳至 页面2





代码如下：



1.AppDelegate.h

#import <UIKit/UIKit.h>

@interface AppDelegate : UIResponder <UIApplicationDelegate>

@property (strong, nonatomic) UIWindow *window;

@property (strong, nonatomic)UINavigationController *navigationController;

@end

2. AppDelegate.m

#import "AppDelegate.h"

#import "FirstViewController.h"

@interface AppDelegate ()

@end

@implementation AppDelegate

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {

UIWindow *window = [[UIWindow alloc]initWithFrame:[[UIScreen mainScreen]bounds]];

FirstViewController *viewController = [[FirstViewController alloc]initWithNibName:@"FirstViewController" bundle:nil];

_navigationController = [[UINavigationController alloc]initWithRootViewController:viewController];

[self.window addSubview:_navigationController.view];

self.window.rootViewController = _navigationController;

// self.window.rootViewController = viewController;

[self.window makeKeyAndVisible];

return YES; return YES;

}

3. FirstViewController.h

#import <UIKit/UIKit.h>

@interface FirstViewController : UIViewController{

}

- (IBAction)pressToSecond:(id)sender;

@end

4.FirstViewController.m

#import "FirstViewController.h"

#import "SecondViewController.h"

#import "AppDelegate.h"

@interface FirstViewController ()

@end

@implementation FirstViewController

- (void)viewDidLoad {

[super viewDidLoad];

// [self.next addTarget:self action:@selector(pressToSecond:) forControlEvents:UIControlEventTouchUpInside];

}

- (void)didReceiveMemoryWarning {

[super didReceiveMemoryWarning];

// Dispose of any resources that can be recreated.

}

- (IBAction)pressToSecond:(id)sender {

SecondViewController *secondView = [[SecondViewController alloc]initWithNibName:@"SecondViewController" bundle:nil];

// 页面跳转：

// 方法1:（传不了值，不知道为什么？？？）

AppDelegate *myDelegate = [[UIApplication sharedApplication]delegate];

[myDelegate.navigationController pushViewController:secondView animated:YES];

}

@end

这样就可以有上面的效果了，但是如果secondViewController里设置此controller的navigationController的

navigationBar就不会自动显示返回按钮了，需要在secondViewController里设置一下。

-(void)viewDidAppear:(BOOL)animated{

[super viewDidAppear:animated];

AppDelegate *myDelegate = [[UIApplication sharedApplication]delegate];

// myDelegate.navigationController.navigationBarHidden = YES;

self.navigationController.navigationBarHidden = YES;

}
