Xamarin Studio / VS for Mac Storyboard无法打开

时间：2017-07-25 14:05:50

标签： c# ios macos xamarin storyboard

我买了一台用于开发iOS通用应用程序的新MacBook Pro。在我销售旧的之前，我将代码推送到BitBucket存储库。

现在我已经安装了VS for Mac和Xamarin Studio，并从bitbucket中提取了源代码。一切都很好（构建，调试等），但在故事板设计师的设计不会工作。

我遇到以下异常：

根据例外我的xml（storyboard）无效且无法解析。不知何故，我能够在旧MacBook（6个月前）上打开故事板。也可以通过XCode Interface Builder打开故事板。

有任何建议如何解决这个问题？我真的不想开始重新设计我的应用程序。

谢谢！

答案 0 :(得分：3)

问题是Xcode界面构建器添加了一个名为＆＃39; device＆＃39;的附加属性。它指定了初始设备设置。使用源代码编辑器打开.xib，然后只需删除＆＃39;设备＆＃39;属性，它应该工作正常。

答案 1 :(得分：1)

经过很长一段时间，没有Xamarin的帮助，我发现问题所在。

我为解决问题所做的步骤：

  1. 将整个错误堆栈复制到编辑器
  2. 从底部开始阅读（照例）
  3. 找出最后发生的异常的位置
  4. 在xml out
    5. 中注释相应的元素/属性
  5. 重复步骤2 - ＆gt; 4直到没有出现错误消息

    6. 在我的案例中，有几个无效元素，例如：

        2017-11-30 23:50:42.8] ERROR: Error in type parser for: UIKit.UIFont
System.NotImplementedException: <font key="NSFont" metaFont="smallSystem" />

    和

    com.xamarin.MTHosting.3d875c911.stderr: 2017-11-30 23:45:45.638 MonoTouchDesignServerUnified[64451:979709] [2017-11-30 23:45:45.6] ERROR: Error in type parser for: UIKit.UIFont
System.NotImplementedException: <font key="NSFont" metaFont="cellTitle" />

    所以我刚用“源代码编辑器”打开了我的故事板，并对这些元素进行了评论。

    最后，我可以再次编辑我的故事板。

答案 2 :(得分：0)

尽管安德烈（Andre）的建议是好的，但在许多情况下仍然无效。 我有一个3年前创建的旧项目，向该项目添加新的故事板会返回此错误。 例如，我找不到类似function registrationSendFunction() { const xhr = new XMLHttpRequest(); const url = "/register"; xhr.open("POST", url, true); xhr.setRequestHeader("Content-Type", "application/json"); let regVariable1 = document.getElementById("username").value; let regVariable2 = document.getElementById("psw2").value; let regVariable3 = document.getElementById("fullname").value; let regVariable4 = document.getElementById("email").value; let regVariable5 = document.getElementById("nationality").value; let regVariable6 = document.getElementById("favourite").value; let registrationDetails = { "username" : regVariable1, "secret" : regVariable2, "fullname" : regVariable3, "emailAddress" : regVariable4, "nationality" : regVariable5, "favourite" : regVariable6 } let dataToSend = JSON.stringify(registrationDetails) xhr.send(dataToSend); xhr.onreadystatechange = function () { if (xhr.readyState === 4 && xhr.status === 200) { regModal.style.display = "none"; } } } 和useTraitCollections的错误。我手动添加了它们，但仍然返回相同的错误。 我在另一个项目上找到了一个有效的情节提要代码，并将其复制到了我不工作的项目中。首先解决此问题，然后您可以修改此情节提要。
