Xcode 9/10 中的代码折叠更改

Code Folding changes in Xcode 9/10

提问by joffd

I know code folding was missing in the early Beta's of Xcode9 and that it is available to fold entire methods with CMD click.

我知道在 Xcode9 的早期 Beta 版中缺少代码折叠，并且可以使用 CMD 单击折叠整个方法。

But in Xcode 8 i was able to fold code in blocks (i.e. individual if statements) via Editor >> Code Folding >> Foldbut in Xcode 9 this folds the entire method.

但是在 Xcode 8 中，我能够通过Editor >> Code Folding >> Fold 将代码折叠成块（即单个 if 语句），但在 Xcode 9 中这折叠了整个方法。

Is there a fix/setting i can change to restore the Xcode 8 functionality?

是否有修复/设置我可以更改以恢复 Xcode 8 功能？

You can fold individual ifstatements also in Xcode 9 however it folds the entire if - (else)expression.

您也可以if在 Xcode 9 中折叠单个语句，但它会折叠整个if - (else)表达式。

Put the cursor somewhere within the block and press ??←

将光标放在块内的某个位置并按 ??←
