xcode 默认启用代码折叠

Enable code-folding by default

提问by Infinite

Is there a way to tell XCode fold methods/functions by default when opening a file?

打开文件时，有没有办法在默认情况下告诉 XCode 折叠方法/函数？

Not sure if this is an OS change, or an Xcode change, but on Lion with Xcode 4, some of these commands cited by Griffo are performed with the Option modifier (the ? key), not control. I've made some changes to reflect this:

不确定这是操作系统更改还是 Xcode 更改，但在带有 Xcode 4 的 Lion 上，Griffo 引用的其中一些命令是使用 Option 修饰符（? 键）执行的，而不是控制。我进行了一些更改以反映这一点：

Fold? ? ? ? ? ? ? ? ? ? ? ???← ? ? ?option+command+left
Unfold ? ? ? ? ? ? ? ? ? ? ???→ ? ? ?option+command+right
Unfold All ? ? ? ? ? ? ? ? ??U ? ? ? ?option+U
Fold Methods/Functions ? ? ???↑ ? ? ?option+command+up
Unfold Methods/Functions ? ???↓ ? ? ?option+command+down

Sorry to necro a thread, but I thought this was worthwhile to revise.

对不起，我死了一个线程，但我认为这是值得修改的。

If you want to fold / unfold specific blocks of code, since Xcode 7, you have to enable that.

如果你想折叠/展开特定的代码块，从 Xcode 7 开始，你必须启用它。

Go to Xcode > Preferences > Text Editing > and check 'Code folding ribbon'.

转到 Xcode > Preferences > Text Editing > 并选中“代码折叠功能区”。

(No idea why they disabled this useful feature by default.)

（不知道为什么他们默认禁用了这个有用的功能。）

I feel your pain. It is difficult to press cmd+option+shift+left every time I open an implementation file to collapse all the methods. I would be grateful to know of a way to set this by default. On the other hand, a probably obvious workaround may be to select the method from the method picker at the top of the window. I suppose this is how the Xcode developers intended us to find methods.. still cmd+option+shift+left is my preference.. it just hurts my hand :/

我感觉到你的痛苦。每次打开一个实现文件都很难按cmd+option+shift+left来折叠所有方法。我很高兴知道默认情况下设置它的方法。另一方面，一个可能明显的解决方法可能是从窗口顶部的方法选择器中选择方法。我想这就是 Xcode 开发人员希望我们找到方法的方式.. 仍然 cmd+option+shift+left 是我的偏好..它只是伤害了我的手：/
