(1) 打开nib文件

(2)点击"File‘s Owner", 按command+4,设置Class为xxxViewControler

(3) 按Control+"Files‘s Owner", 里面有个默认的IBOutlet变量view, 看一下后面有没有做关联，如果没有就拉到下面的View和视图做个关联

FirstViewController* firstViewController =[[FirstViewControlleralloc]initWithNibName:@"firstTT"bundle:nil];

2.用storyboard  中的View Controller 创建view界面

 1.在storyboard中创建view controller 界面

  

 2.把storyboard 中的view controller Sotryboard ID 设置为first

3.添加代码 创建界面

UIStoryboard *futureStoryBoard = [UIStoryboardstoryboardWithName:@"Main"bundle:nil];

FirstViewController* firstViewController = [futureStoryBoard instantiateViewControllerWithIdentifier:@"first"];

为了大家写代码时能有完整参考，特传上了源码
