一 于StoryBoard相关的类、方法和属性

1 UIStoryboard

 // 根据StoryBoard名字获取StoryBoard+ (UIStoryboard *)storyboardWithName:(NSString *)name bundle:(nullabßle NSBundle *)storyboardBundleOrNil;// 获取指定StoryBoard的第一个视图控制器- (nullable __kindof UIViewController *)instantiateInitialViewController;// 获取指定StoryBoard的标识符为identifier的视图控制器- (__kindof UIViewController *)instantiateViewControllerWithIdentifier:(NSString *)identifier;

2 UIStoryboardSegue

 // 标识符@property (nullable, nonatomic, copy, readonly) NSString *identifier;// 源视图控制器@property (nonatomic, readonly) __kindof UIViewController *sourceViewController;// 目的视图控制器@property (nonatomic, readonly) __kindof UIViewController *destinationViewController;

3 UIStoryboardUnwindSegueSource

4 UIStoryboardPopoverSegue

5 UIViewController

 // 处理标识符为identifier的StoryBoardSegue- (void)performSegueWithIdentifier:(NSString *)identifier sender:(nullable id)sender NS_AVAILABLE_IOS(5_0);

二 动态加载StoryBoard

AppDelegate.m 动态加载StoryBoard，TARGETS设置中Deployment Info 项Main Interface删除main

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];self.window.backgroundColor = [UIColor whiteColor];[self.window makeKeyAndVisible];UIViewController *vc = [[UIStoryboard storyboardWithName:@"Main" bundle:nil] instantiateInitialViewController];self.window.rootViewController = vc;return YES;
}

三 StoryBoard->StoryBoard切换和传值

1 视图切换

方法一：

方法二：

// StoryBoard 跳转到 StoryBoard
- (IBAction)StoryBoardCodePushButton:(id)sender
{// 已经连线的seg[self performSegueWithIdentifier:@"Detail" sender:self];
}

2 视图传值

// UIViewController 方法 用于处理视图控制器之间的传值
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{if ([sender isKindOfClass:[UIButton class]]){// 方法一,使用KVC给B 也就是目标场景传值UIViewController *destinationController=[segue destinationViewController];[destinationController setValue:@"StoryBoard Segue Push" forKey:@"name"];}else{// 方法2,使用属性传值,需导入相关的类.hDetailViewController *bController=[segue destinationViewController];bController.name=@"StoryBoard Code Push";}
}

四 StoryBoard->Code视图控制器切换和传值（Xib视图控制器原理一样）

self视图控制器是用StoryBoard创建的

// StoryBoard 跳转到 Code
- (IBAction)StoryBoardtoCodeVCPush:(id)sender
{CodeViewController *vc = [[CodeViewController alloc] init];vc.name = @"StoryBoard to CodeVC Push";[self.navigationController pushViewController:vc animated:YES];
}

五 Code视图控制器->StoryBoard切换和传值（Xib视图控制器原理一样）

self视图控制器是用Code（Xib）创建的

- (void)barButton
{// 从Code视图控制器跳转到StoryBoard中的视图控制器 （Xib原理一样）UIStoryboard *story = [UIStoryboard storyboardWithName:@"Main" bundle:nil];DetailViewController *vc = [story instantiateViewControllerWithIdentifier:@"VC"];vc.name = @"Code to StoryBoard Push";[self.navigationController pushViewController:vc animated:YES];
}
