Question

如何在一个视图控制器类中用Swift调用Storyboard

Answer 1

首先你要在storyboard里面设置这个vc对应的Storyboard ID，如图

然后你在代码里就能直接通过这个id加载这个对象了

XXXViewController *vc = [self.storyboard instantiateViewControllerWithIdentifier:@"xx_id"];

如果
self.storyboard为nil
可以用

UIStoryboard* storyboard = [UIStoryboard storyboardWithName:@"XX_storyboard_name" bundle:[NSBundle mainBundle]];  
XXXViewController *vc = [storyboard instantiateViewControllerWithIdentifier:@"xx_id"];
