ios5 storyboard 代码获取独立的 viewController对象

//1.storyboard中定义某个独立newViewController（无segue跳转关系）的 identifier

static NSString *controllerId =@"newViewController";

//2.获取UIStoryboard对象

UIStoryboard *story = [UIStoryboard storyboardWithName:@"MainStoryboard" bundle:nil];

//3.从storyboard取得newViewCtroller对象，通过Identifier区分

newViewController *nvc = [storyinstantiateViewControllerWithIdentifier:controllerId];

//4.对newViewController进行压栈实现tableview跳转到newTableview

[ [selfnavigationController]pushViewController:nvc animated:YES ];

if([selfnavigationController] != nil)

NSLog(@"self.navigationController is not nil");

else {

NSLog(@"self.navigationController is nil");

}
