X code不让步自动完成任何有用的信息 [英] XCode does not give any useful information in autocomplete

问题描述

在旧版本的X $ C $的c（提前X code 4.1），按Esc键会给一个非常有用的自动完成窗口，其中包括可用任何方法的返回值。然而，在X $ C $ 4.1Ç，按Esc键给出了一个更实用的自动完成帮手。它DOS不给的方法的返回值，并只列出的方法和已经被利用在当前文件中的变量。有没有一种方法来找回昔日的功能，这是更加有用？

In older versions of Xcode (before Xcode 4.1), hitting ESC would give a very useful autocomplete window, including the return value of any methods available. However, in XCode 4.1, hitting ESC gives a much less useful autocomplete helper. It dos not give the return value of methods, and only lists methods and variables which have already been utilized in the current file. Is there a way to get back the old functionality, which was much more useful?

推荐答案

尝试删除持有该项目的索引信息导出数据文件夹（类和放大器;在项目中采用的方法）并重新打开该项目。这样做会踢X code的索引。

Try deleting derived data folder which holds the project's index information (classes & methods employed in the project) and reopening the project. Doing so will kick in the indexer of Xcode.

路径导出数据文件夹可在主办单位的发现（为Cmd + Shift + 2）项目选项卡。

Path to derived data folder can be found in Organizer's (Cmd+Shift+2) Projects tab.
