Xcode crashes when I try to create a outlet from a UIWebview to Header file
提问by Steve Sahayadarlin
I am currently using Xcode 5 on my Macbook Pro which is running OSX Yosemite. I am trying to create an outlet from a UIWebview to a header file. When I let go of my mouse to create the connection, Xcode freezes and crashes. This is repeatedly happening no matter what I have done. I have tried restarting Xcode and my Macbook. Does anyone else have this problem or know how to fix it? Thanks!
我目前在运行 OSX Yosemite 的 Macbook Pro 上使用 Xcode 5。我正在尝试创建一个从 UIWebview 到头文件的插座。当我松开鼠标创建连接时，Xcode 冻结并崩溃。无论我做了什么，这都会反复发生。我尝试重新启动 Xcode 和我的 Macbook。有没有其他人有这个问题或知道如何解决它？谢谢！
I have added the logs from the crash(I couldn't include the backtrace because it exceeded the maximum characters in the body)
我已经添加了崩溃的日志（我无法包含回溯，因为它超过了正文中的最大字符数）

I think you should declare a IBOutlet in your header file. And then in Storyboard you try to connect the header file.
我认为您应该在头文件中声明一个 IBOutlet。然后在 Storyboard 中尝试连接头文件。
回答by Sai
Have you ever tried to clean your product(Product->Clean)? Then, open the xib file as source code and delete your IBOutlet info. Maybe XCode get confused about your IBOutlet.
你有没有试过清洁你的产品（产品->清洁）？然后，打开 xib 文件作为源代码并删除您的 IBOutlet 信息。也许 XCode 对您的 IBOutlet 感到困惑。
