Xcode custom font not showing in app
提问by Blip
I have downloaded Open Sans font and added all the .tfffiles into my Xcode project, and have checked the checkbox in "Target Membership" pane for each file. I have added the UIAppFontskey and values in Info.plist, and I am sure that the values are typo-free. Plus, the .tfffiles are added to "Copy Bundle Resources", and the custom font is showing up in Interface Builder. And then I changed the font of all the labels to Open Sans in the Interface Builder (no code).
我已经下载了 Open Sans 字体并将所有.tff文件添加到我的 Xcode 项目中，并选中了每个文件的“目标成员资格”窗格中的复选框。我已经UIAppFonts在 Info.plist 中添加了键和值，并且我确信这些值没有拼写错误。另外，这些.tff文件被添加到“Copy Bundle Resources”中，并且自定义字体显示在 Interface Builder 中。然后我在 Interface Builder 中将所有标签的字体更改为 Open Sans（无代码）。
But when I run the app in the simulator, all the labels and buttons are showing the system font in ultra small sizes, like this:
但是当我在模拟器中运行该应用程序时，所有标签和按钮都以超小尺寸显示系统字体，如下所示：
One thing to note is that I am using Xcode 7 beta 5, and the app's Base SDK is iOS 9.
需要注意的一件事是，我使用的是 Xcode 7 beta 5，并且该应用程序的 Base SDK 是 iOS 9。
But why is there this problem? Is it a bug? Thanks!
但是为什么会出现这个问题呢？这是一个错误吗？谢谢！

Check That fonts inside the proyect are part of the target. Select fonts, verify the property Target Membershipfor your app is checkedat the right in File Inspector.
检查项目内的字体是否是目标的一部分。选择字体，确认在 File Inspector 的右侧选中了应用程序的Target Membership属性。
That solved the problem for me:

Blip, here's a photo of what I did in an empty "Single View" project. And, I could see the font on sim and IB editor. Anything look different for your project? Maybe recreate the basics in a new project, just to double check? All of my notes on the image were associated with my original thoughts...just use them for reference as you double check things.
Blip，这是我在一个空的“单一视图”项目中所做的照片。而且，我可以在 sim 和 IB 编辑器上看到字体。您的项目有什么不同吗？也许在新项目中重新创建基础知识，只是为了仔细检查？我在图像上的所有笔记都与我的原始想法相关……请在仔细检查时将它们用作参考。

I recently encountered this problem too. But it only happened for one font-style of a font-family, the others worked fine. I could only solve it by using this font in a button, then the font was also available for other controls such as labels or the large title.
我最近也遇到了这个问题。但它只发生在一个字体系列的一种字体样式上，其他的工作正常。我只能通过在按钮中使用这种字体来解决它，然后该字体也可用于其他控件，例如标签或大标题。
