// 一、根据StoryboardID(需要在Storyboard设置)，通过ViewController所在的Storyboard来加载：UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"Main" bundle:nil];UIViewController *vc = [storyboard instantiateViewControllerWithIdentifier:@"FicowVC"];// 二、通过UIViewController对应的.xib文件加载：UIViewController *vc = [[UIViewController alloc] initWithNibName:@"FicowVC" bundle:nil];// 三、直接加载UIViewController类:UIViewController *vc = [[UIViewController alloc] init];/*注意：loadNibNamed和initWithNibName需要加载的xib文件是不一样的。initWithNibName需要加载的xib文件的File Owner应改是需要加载的类，而loadNibNamed需要加载的xib文件的File Owner为NSObject。*/
