objective-c - Xcode block (NSMallocBlock) 缩进(大括号自动从新行开始)

Question

我想用大括号从新行开始打开 block 。

让我们远离关于这是否是一个好的决定的哲学讨论 -- 不管“哪里”和“何时”，“如何”仍然是绝对的。

所以，问题描述如下:

有什么办法可以实现吗？

---

找了半天，没找到解决办法。

我已经知道这样的事情:

1. Snippet Edit -- 这个小程序将允许编辑默认 Xcode 的代码片段。因此，您将能够在 if、for、while 等中从新行打开大括号。但是，这不允许更改 block 缩进。

2. Uncrustify -- 这可能会解决我的问题，但看起来并不容易设置。而且它只会在代码编写完成后对其进行格式化，而不是在“进行中”进行格式化。此外，即使我正确设置了 uncrustify，它仍然会很慢——大约需要点击 4 次鼠标来格式化 block ，这很耗时。

有人知道任何其他解决方案吗？

编辑:

更具体地说，我希望在这一步按下 ENTER 时立即缩进该 block :

我找到的最简单的解决方案是:

下载Karabiner并更改您的 private.xml(您还可以查看文档 here)

您的 private.xml 可能如下所示:

<?xml version="1.0"?>
<root>
    <item>
        <name>Command+Enter to complete single block</name>
        <identifier>private.swap_cmnd+Enter_to_complete__single_block</identifier>
        <autogen>
            __KeyToKey__
            KeyCode::RETURN, ModifierFlag::COMMAND_L | ModifierFlag::NONE,
            KeyCode::RETURN,

            KeyCode::CURSOR_DOWN,
            KeyCode::CURSOR_RIGHT, ModifierFlag::COMMAND_L,
            KeyCode::DELETE, ModifierFlag::COMMAND_L,
            KeyCode::BRACKET_RIGHT, ModifierFlag::SHIFT_L,
            KeyCode::BRACKET_RIGHT,
            KeyCode::SEMICOLON,
            KeyCode::CURSOR_UP,
            KeyCode::CURSOR_UP,
            KeyCode::CURSOR_RIGHT, ModifierFlag::COMMAND_L,
            KeyCode::CURSOR_LEFT,
            KeyCode::RETURN,
            KeyCode::CURSOR_DOWN,
            KeyCode::CURSOR_DOWN,
            KeyCode::CURSOR_RIGHT, ModifierFlag::COMMAND_L,

            KeyCode::CURSOR_UP, ModifierFlag::SHIFT_L,
            KeyCode::CURSOR_UP, ModifierFlag::SHIFT_L,
            KeyCode::CURSOR_UP, ModifierFlag::SHIFT_L,

            KeyCode::I, ModifierFlag::CONTROL_L,
            KeyCode::CURSOR_RIGHT,
            KeyCode::CURSOR_UP,
            KeyCode::CURSOR_LEFT, ModifierFlag::SHIFT_L,
            KeyCode::TAB,
        </autogen>
    </item>

    <item>
        <name>Option+Enter to complete double block</name>

            __KeyToKey__
            KeyCode::RETURN, ModifierFlag::OPTION_L | ModifierFlag::NONE,
            KeyCode::CURSOR_RIGHT,
            KeyCode::RETURN,
            KeyCode::CURSOR_UP,
            KeyCode::CURSOR_LEFT, ModifierFlag::COMMAND_L,
            KeyCode::TAB,

            KeyCode::RETURN,

            KeyCode::CURSOR_DOWN,
            KeyCode::CURSOR_DOWN,
            KeyCode::CURSOR_LEFT, ModifierFlag::COMMAND_L,
            KeyCode::TAB,
            KeyCode::RETURN,
            KeyCode::DELETE,
            KeyCode::CURSOR_DOWN,

            KeyCode::CURSOR_UP,
            KeyCode::CURSOR_RIGHT, ModifierFlag::COMMAND_L,
            KeyCode::CURSOR_LEFT,
            KeyCode::RETURN,
            KeyCode::CURSOR_UP,
            KeyCode::CURSOR_UP,
            KeyCode::CURSOR_UP,
            KeyCode::CURSOR_UP,
            KeyCode::CURSOR_RIGHT, ModifierFlag::COMMAND_L,
            KeyCode::CURSOR_LEFT,

            KeyCode::CURSOR_DOWN,
            KeyCode::CURSOR_DOWN,
            KeyCode::CURSOR_DOWN,
            KeyCode::CURSOR_DOWN,
            KeyCode::CURSOR_RIGHT, ModifierFlag::COMMAND_L,

            KeyCode::CURSOR_UP, ModifierFlag::SHIFT_L,
            KeyCode::CURSOR_UP, ModifierFlag::SHIFT_L,
            KeyCode::CURSOR_UP, ModifierFlag::SHIFT_L,
            KeyCode::CURSOR_UP, ModifierFlag::SHIFT_L,
            KeyCode::CURSOR_UP, ModifierFlag::SHIFT_L,
            KeyCode::CURSOR_UP, ModifierFlag::SHIFT_L,
            KeyCode::CURSOR_UP, ModifierFlag::SHIFT_L,

            KeyCode::I, ModifierFlag::CONTROL_L,
            KeyCode::CURSOR_RIGHT,
            KeyCode::CURSOR_UP,
            KeyCode::CURSOR_UP,
            KeyCode::CURSOR_UP,
            KeyCode::CURSOR_UP,
            KeyCode::CURSOR_UP,
            KeyCode::CURSOR_LEFT, ModifierFlag::COMMAND_L,
            KeyCode::TAB,
        </autogen>
    </item>
</root>

完成此操作后，您现在可以通过按 ⌘+ENTER(而不是按 ENTER，打开区 block 时按⌘+ENTER)。这是 preview (放慢速度，以便您看到详细信息)。

以上仅适用于单个 block 。如果你想一次打开两个 block ，你可以按ALT+ENTER。这是 preview (放慢速度，以便您看到详细信息)。

这是 preview与实际速度:
