Loading obj-c files with storyboard in Swift project
问题
我是Swift世界的新手，已经创建了一个非常基本的应用程序，从名为Main的故事板控制器加载了3个视图。
@IBAction func view2ButtonClicked(_ sender: Any) {
if let vc = self.storyboard?.instantiateViewController(withIdentifier: String(describing: Test2ViewController.self)) as? Test2ViewController {
self.navigationController?.pushViewController(vc, animated: true)
}
}
@IBAction func view3ButtonClicked(_ sender: Any) {
if let vc = self.storyboard?.instantiateViewController(withIdentifier: String(describing: Test3ViewController.self)) as? Test3ViewController {
self.navigationController?.pushViewController(vc, animated: true)
}
}
然而，我还复制了一个.h和.m文件，以及一个来自较旧的obj-c项目的故事板。我已经设置了桥接头文件，并尝试使用以下方法加载它：
@IBAction func view1ButtonClicked(_ sender: Any) {
let storyboard = UIStoryboard(name: "CompassView", bundle: nil)
let vc = storyboard.instantiateViewController(withIdentifier: "CompassViewController")
self.navigationController!.pushViewController(vc, animated: true)
}
但是它崩溃并显示以下错误：
*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'Could not find a storyboard named 'CompassView' in bundle NSBundle
当我找到Compass故事板文件时，我检查了名称，它是Compass.storyboard，自定义类是CompassViewController，故事板ID是CompassView。
英文:
I am new to the Swift world, and have created a very basic app that loads up 3 views from a storyboard controller called Main
@IBAction func view2ButtonClicked(_ sender: Any) {
if let vc = self.storyboard?.instantiateViewController(withIdentifier: String(describing: Test2ViewController.self)) as? Test2ViewController {
self.navigationController?.pushViewController(vc, animated: true)
}
}
@IBAction func view3ButtonClicked(_ sender: Any) {
if let vc = self.storyboard?.instantiateViewController(withIdentifier: String(describing: Test3ViewController.self)) as? Test3ViewController {
self.navigationController?.pushViewController(vc, animated: true)
}
}
However, I have also copied over a .h & .m as well as a storyboard from an older obj-c project, I have setup the bridging header, and I am trying to load it using the following method;
@IBAction func view1ButtonClicked(_ sender: Any) {
let storyboard = UIStoryboard(name: "CompassView", bundle: nil)
let vc = storyboard.instantiateViewController(withIdentifier: "CompassViewController")
self.navigationController!.pushViewController(vc, animated: true)
}
However it crashes with the error;
*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'Could not find a storyboard named 'CompassView' in bundle NSBundle
When I locate the Compass storyboard file, I check the name and it is Compass.storyboard
and the custom class is CompassViewController and storyboard ID is CompassView

得分: 2
当我找到Compass的故事板文件时，我检查名称，它是Compass.storyboard，然后您应该像这样加载它：
let storyboard = UIStoryboard(name: "Compass", bundle: nil)
英文:
> When I locate the Compass storyboard file, I check the name and it is Compass.storyboard
then you should load it like this
let storyboard = UIStoryboard(name: "Compass", bundle: nil)
