原地址：http://blog.youkuaiyun.com/lrenjun/article/details/10235687

1. 从xib的viewcontroll中启动storyboard   或者   从一个storyboard切换到另一个storyboard：

[cpp]  view plain copy

1. - (IBAction)openStoryboard:(id)sender {    
2.     UIStoryboard *secondStoryboard = [UIStoryboard storyboardWithName:@"SecondStoryboard" bundle:nil];    
3.     [self presentModalViewController:[secondStoryboard instantiateInitialViewController] animated:YES];    
4. }  

2. 从storyboard切换到xib：

[plain]  view plain copy

1. LoginViewController *loginViewController = [[LoginViewController alloc] initWithNibName:@"LoginViewController" bundle:nil];    

然后用push或者modal方法启用这个controller

3. 从xib或者storyboard中启动里一个storyboard的某一个controller上：

[cpp]  view plain copy

1. [storyboard instantiateViewControllerWithIdentifier"actionList"];
