XCode Show Function Parameters Hotkey
提问by Mr. Smith
One of the few things I haven't figured out how to do in XCode that I could do in Visual Studio is list the parameters of a function. I've Googled this a few times now, and still haven't found an answer.
我还没有想出如何在 XCode 中做而我可以在 Visual Studio 中做的几件事之一是列出函数的参数。我已经在谷歌上搜索了几次，但仍然没有找到答案。
If I start typing out, for example round(I get a list of the parameters and its return type. However, if I already typed out the code
例如，如果我开始输入，round(我会得到一个参数列表及其返回类型。但是，如果我已经输入了代码
x = round(y);
and I cursor over to it, I don't know how to show parameter info without retyping it. Anyone know how the hotkey for this?
我将光标移到它上面，我不知道如何在不重新键入的情况下显示参数信息。有谁知道这个的热键如何？

Just discovered Option + Escapeby browsing through the XCode Preferences Hotkeys section. It actually lists the parameter info in a tooltip (no other hotkey I've seen so far does this!), but isn't quite as friendly as Visual Studio's Ctrl+Shift+Space function. For instance, the text selection cursor (caret) must be on the function name (not on a parameter to that function).
刚刚通过浏览 XCode 首选项热键部分发现了Option + Escape。它实际上在工具提示中列出了参数信息（到目前为止我还没有看到其他热键可以这样做！），但不如 Visual Studio 的 Ctrl+Shift+Space 功能那么友好。例如，文本选择光标（插入符号）必须位于函数名称上（而不是该函数的参数上）。
Having explored the XCode hotkeys exhaustively, I'm going to assume that this is the best it gets in XCode.
在详尽地探索了 XCode 热键之后，我将假设这是 XCode 中最好的。

Control + Command + Shift + /is the keyboard equivalent of Option + click mentioned in other answers
Control + Command + Shift + /是等价于其他答案中提到的 Option + click 的键盘吗

Command + clickthe function will navigate you to the function definition, while Option + clickbrings up tooltip of function definition.
Command + 单击函数将导航到函数定义，而Option + 单击会显示函数定义的工具提示。
