IOS中用UIStoryBoard类初始化/跳转控制器

1.空工程中通过创建storyboard文件加载页面

//获取Main.storyboard

UIStoryboard
*mainStory = [UIStoryboard
storyboardWithName:@"Main"
bundle:nil];

//获取Main.storyboard中的第2个视图

SecondViewController
*secondController = [mainStory
instantiateViewControllerWithIdentifier:@"SecondStory"];

//设置窗体的根视图为Storyboard里的视图

self.window.rootViewController
= secondController

StoryBoard的ID在这里设置:

2. 其他控制器中设置StoryBoard的初始控制器为window的根控制器

UIStoryboard *stotyb = [UIStoryboard storyboardWithName:@"Second" bundle:nil];

[self.view.window setRootViewController:stotyb.instantiateInitialViewController];

3.跳转到Storyboard中某个控制器

//获取Main.storyboard

UIStoryboard
*mainStory = [UIStoryboard
storyboardWithName:@"Main"
bundle:nil];

//获取Main.storyboard中的第2个视图

SecondViewController
*secondController = [mainStory
instantiateViewControllerWithIdentifier:@"SecondStory"];

//跳转页面

[self
presentViewController:secondController
animated:YES
completion:nil];
