storyboard not opening in xamarin ios designer
提问by ncruz
This is my first project with Xamarin.iOS and am getting familiarized with the IDE for iOS.
这是我使用 Xamarin.iOS 的第一个项目，并且正在熟悉适用于 iOS 的 IDE。
I created a simple Xamarin.iOS 'Single Page Application' project. I did not add any code - the project files are as they are when created from 'New Project'.
我创建了一个简单的 Xamarin.iOS 'Single Page Application' 项目。我没有添加任何代码 - 项目文件与从“新项目”创建时一样。
When opening the main storyboard file in Xamarin Studio, the spinner image just keeps spinning and hangs. When I try to close Studio, it also hangs. I have to kill the process in Activity Monitor.
在 Xamarin Studio 中打开主情节提要文件时，微调器图像只是不断旋转并挂起。当我尝试关闭 Studio 时，它也会挂起。我必须在活动监视器中终止该进程。
If I open the storyboard in 'Source Code Editor' or in Xcode Interface Builder, it opens fine.
如果我在“源代码编辑器”或 Xcode Interface Builder 中打开故事板，它会打开得很好。
I did some research and saw this discussion thread on the Xamarin forums: https://forums.xamarin.com/discussion/23566/ios-designer-bug-there-was-problem-rendering-this-document-not-opening-storyboard
我做了一些研究，并在 Xamarin 论坛上看到了这个讨论主题：https: //forums.xamarin.com/discussion/23566/ios-designer-bug-there-was-problem-rendering-this-document-not-opening-故事板
I tried the solution that was mentioned by user Krunoslavterle, by opening the
storyboard in code editor but it still does not open. Here's what he posted:
"I had the same issue, resolved by opening storyboard with TextEdit,
there I changed: version="3.0" to 2.0, save, refresh and try to open the
storyboard. Xamarin studio will throw an error ("The format of this
legacy storyboard file is not supported"), then click on ("Upgrade this
file to a supported format"). After that the storyboard can be opened."
我尝试了用户 Krunoslavterle 提到的解决方案，在代码编辑器中打开故事板，但它仍然没有打开。这是他发布的内容：
“我遇到了同样的问题，通过使用 TextEdit 打开故事板解决了，我将：version="3.0" 更改为 2.0，保存、刷新并尝试打开故事板。Xamarin Studio 将抛出错误（“The不支持此旧故事板文件的格式”），然后单击（“将此文件升级为支持的格式”）。之后即可打开故事板。”
I have checked memory usage to see if it doesn't have enough to open and render the storyboard and it has enough memory to spare.
我已经检查了内存使用情况，看看它是否没有足够的内存来打开和渲染故事板，并且它有足够的内存来备用。
I opened Console.app and saw .spin and .hang logs that I can provide but am not comfortable in posting them publicly as they probably have sensitive info.
我打开了 Console.app 并看到了我可以提供的 .spin 和 .hang 日志，但我不愿意公开发布它们，因为它们可能包含敏感信息。

尝试从 beta 频道更新 xamarin studio。我遇到了同样的问题，从 beta 频道故事板更新 xamarin studio 后开始加载。

Got it to open by adding more memory - went from 2GB to 4GB - and now it opens, but it takes 1-2 minutes. I recommend having at least 6GB and ideally 8-10GB.
通过添加更多内存来打开它 - 从 2GB 到 4GB - 现在它打开了，但需要 1-2 分钟。我建议至少有 6GB，最好是 8-10GB。

My best advice is to NEVERuse the IOS designer. It's rubbish. Always use Xcode Interface Builder. The main reason is, you're guaranteed the storyboard will be valid with IOS. I once created an empty storyboard in IOS Designer and compared the XML it generated to an empty storyboard created in Xcode. It was totally different. The designer version was missing a hell of a lot of information. Since then I have never trusted the IOS designer. Not only that, but constraints are pain in the ass to use on the IOS designer, whereby, they're a lot easier in Xcode. I've also have storyboards render totally wrong in the IOS designer if the layout is particularly complex.
我最好的建议是NEVER使用IOS designer. 这是垃圾。始终使用 Xcode Interface Builder。主要原因是，您可以保证故事板对 IOS 有效。我曾经在 IOS 设计器中创建了一个空的故事板，并将它生成的 XML 与在 Xcode 中创建的空的故事板进行了比较。这是完全不同的。设计师版本缺少大量信息。从那以后我就再也不相信IOS设计师了。不仅如此，在 IOS 设计器上使用约束也很麻烦，因此，它们在 Xcode 中要容易得多。如果布局特别复杂，我也会让故事板在 IOS 设计器中呈现完全错误。
