代碼中建立：

1、appdelegate 該contoller放置controller下一個

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions{    self.window = [[UIWindow alloc] initWithFrame:[UIScreen mainScreen].bounds];        self.window.rootViewController = [[MJOneViewController alloc] init];        [self.window makeKeyAndVisible];    return YES;}

2、oneViewController跳轉的action

拿到要跳轉的控制器的，然後通過當前的controller 來 調用 presentViewController

- (IBAction)jump {    // 展示MJTwoViewController    MJTwoViewController *two = [[MJTwoViewController alloc] init];        UINavigationController *nav = [[UINavigationController alloc] initWithRootViewController:two];        [self presentViewController:nav animated:YES completion:^{        NSLog(@"展示MJTwoViewController完成.......");    }];}

3、twoController 返回之前的controller

調用 dismissViewController方法

- (IBAction)cancel {//    NSLog(@"%@", self.view.window.rootViewController);//    NSLog(@"%@", self.view.window.subviews);    [self dismissViewControllerAnimated:YES completion:^{        NSLog(@"關閉MJTwoViewController....");    }];//    [self.navigationController dismissViewControllerAnimated:YES completion:^{//        NSLog(@"關閉MJTwoViewController....");//    }];}

在storyBoard建立modal控制器也非常方便。直接ctrl  右鍵點擊 選舉moadal狀態
