将 swift class 导入 objective c 故事板

Question

我正在尝试将实施项目 https://github.com/ariok/BWWalkthrough 集成到我的 objective c 项目中。

我有一个 Xcode 自动为我创建的 objc 桥接 header

我翻译了 ViewController.swift 代码

UIStoryboard *sb = [UIStoryboard storyboardWithName:@"Walkthrough" bundle:nil];
BWWalkthroughViewController *walkthrough = [sb instantiateViewControllerWithIdentifier:@"walk"];
BWWalkthroughPageViewController *page_zero = [sb instantiateViewControllerWithIdentifier:@"walk0"];
BWWalkthroughPageViewController *page_one = [sb instantiateViewControllerWithIdentifier:@"walk1"];
BWWalkthroughPageViewController *page_two = [sb instantiateViewControllerWithIdentifier:@"walk2"];
BWWalkthroughPageViewController *page_three = [sb instantiateViewControllerWithIdentifier:@"walk3"];

walkthrough.delegate = self;
[walkthrough addViewController:page_zero];
[walkthrough addViewController:page_one];
[walkthrough addViewController:page_two];
[walkthrough addViewController:page_three];

[self presentViewController:walkthrough animated:YES completion:nil];

然后我像这样导入 swift classes:

进口"SkipTheLine-Swift.h"

我的桥接 header 文件的名称是 "SkipTheLine-Bridging-Header.h"

现在，当我运行代码时，我得到了这个

关于如何在界面生成器中使用 swift 代码有什么想法吗？

Answer 1

想通了！

您只需要在界面生成器中将MODULE编辑为项目名称即可！！
