IOS开发：xib和storyboard的混用

转自：http://blog.csdn.net/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：

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

2. 从storyboard切换到xib：

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：

[storyboard instantiateViewControllerWithIdentifier"actionList"];

4、storyBoard指向一个自身添加的控制器：

//加载storyBoard(这里加载的是名称为Main的storyBoard,并不会创建storyBoard中的控件或控制器)
UIStoryboard * loginStoryBoard = [UIStoryboard storyboardWithName:@"Main" bundle:[NSBundle mainBundle]];

//这个方式代表只加载的storyBoard箭头所指向的控制器
LoginViewController * loginVC = [loginStoryBoard instantiateViewControllerWithIdentifier:@"login"];

//将控制器显示出来
[self showViewController:loginVC sender:nil];

5、StoryBoard 在xcode中只有三个方法：

+ (UIStoryboard *)storyboardWithName:(NSString *)name bundle:(NSBundle *)storyboardBundleOrNil;

- (id)instantiateInitialViewController;
- (id)instantiateViewControllerWithIdentifier:(NSString *)identifier;
