更新CocoaPods需要Xcode命令行工具

问题描述：想更新CocoaPods，在终端运行sudo gem update cocoapods，出现如下错误：

Updating cocoapods
Building native extensions. This could take a while...
ERROR: Error installing cocoapods:
ERROR: Failed to build gem native extension.

问题解决：Go to Xcode, Preferences -> Downloads，download Command Line Tools.

Xcode中Git提交问题

问题描述：今天在做TAG App用Xcode中的Git提交代码，出现如下错误：

The working copy "ViewDeck" failed to commit files.

error: pathspec 'IIWrapController.m' did not match any file(s) known to git.
error: pathspec 'IIWrapController.h' did not match any file(s) known to git.

error: pathspec 'IISideController.h' did not match any file(s) known to git.

问题解决：用GitHub进行提交，OK了

Undo “New Group from Selection” project

问题描述：今天在做TAG App 时在Project上不小心“New Group from Selection” 了下。然后无法撤销了。。。Project上就一直顶着一个New Group。

问题解决：

  1. close xcode
  2. right click on your project's .xcodeproj, then click "Show Package Contents"
  3. inside .xcodeproj, remove the project.xcworkspace
  4. save it and re-open your xcode project and it would be rebuild the file

 

使用Uncrustify在Xcode中格式化Objective-C代码（转）

Xcode是开发iOS应用和Mac OS应用的必备工具，但这个工具的辅助功能相对于Eclipse之类的IDE来说，还是比较少，在Eclipse里只要按Ctrl+Shift+F，就可以将Java代码格式化得非常好看。而在Xcode里，只有Re-Indent（Ctrl+I）这一个调整缩进的功能，显然不够用。

如果想要完成完备的代码格式化，得要借助Uncrustify这样的工具。更进一步，我们用Automate配置一个针对Text的Service，再加上快捷键，就可以在Xcode里间接实现和Eclipse同样效果的代码格式化功能了。

首先安装Uncrustify工具。安装的方法很多，推荐用Homebrew来安装。如果机器上没有Homebrew，先用这条命令安装：

/usr/bin/ruby -e "$(curl -fksSL http://u.aodaren.com/homebrew)"

安装好Homebrew后，用这条命令安装Uncrustify：

brew install uncrustify

详细的Automate配置步骤可以参考这篇文章，如果不想自己配置，也可以直接下载已经配置好的workflow包，复制到~/Library/Services/，并解压就可以了：

mv Uncrustify-Objective-C.workflow.tar.gz ~/Library/Services/
cd ~/Library/Services/
tar zxvf Uncrustify-Objective-C.workflow.tar.gz

下载针对Objective-C语言的Uncrustify配置文件，移动到 ~/ 目录，并更名为 .uncrustify_obj_c.cfg，注意目标文件名前面有个 .：

mv uncrustify_obj_c.txt ~/.uncrustify_obj_c.cfg

如果上面已经顺利完成，那么现在到Xcode里选中一段代码，点右键，在Services里面应该已经有一个Uncrustify Objective-C服务了。选择后，即可将代码格式化。当然，如果每次都点鼠标显然太麻烦，下面来配置快捷键。

点屏幕左上角的苹果图标，选 System Preferences – Keyboard – Keyboard Shortcuts – Services，在Text分区里，找到刚添加的服务Uncrustify Objective-C，给这个服务加上快捷键。注意不要和Xcode里其它快捷键冲突，推荐设置为：Opt+Cmd+字母O。

这样以后在Xcode里，先用Cmd+A全选代码，再用Opt+Cmd+O来格式化代码。整个效果和Eclipse基本上差不多。

最后，如果对格式有不同的需求，还可以修改cfg文件里的设置，每个选项都有详细的说明，这里就不再赘述了。

Could-HllmatoMacBook-Pro:~ CouldHll$

问题解决：安装脚本是需要在安装程序目录的，所以要先进入安装目录：

Could-HllmatoMacBook-Pro:cocos2d-x-2.1.4 CouldHll$ cd /Users/CouldHll/Downloads/cocos2d-x-2.1.4

然后安装，一切正常。

Xcode设置代码提示的左花括号换行单独成行

Xcode代码提示生成源代码程序块默认格式如下，注意左花括号的位置：

if ( condition ) {
do ...
}

因为以前的使用习惯，我想让自动生成的左右花括号都单独成行，变成下面的样子：

if ( condition )
{
do ...
}

在Terminal里面，运行下面命令，然后重启Xcode：

defaults write com.apple.Xcode XCCodeSenseFormattingOptions -dict BlockSeparator "\n"

这个命令修改了~/Library/Preferences/com.apple.Xcode.plist，这是Xcode的配置文件
