最近遇到了两次电脑（RMBP）插入耳机后耳机无声的问题，第一次重启解决，第二次不想重启，在做了一番搜索尝试后，最终的有效方案是重新加载下驱动。在终端执行如下命令即可:

sudo kextunload /System/Library/Extensions/AppleHDA.kext

希望可以帮到有类似烦恼的人。

Recently I have open-sourced my projectTCTitleLoading and made it supporting Cocoapods. Below is the procedure.

1. Create Your Project and Submit It to Github

Create your project and submit it to Github，Record the address for later useage, for example：https://github.com/TravelC/TCTitleLoading.git

2. Create a Branch for Cocoapods

Create a branch for Cocoapods. Naming it with version number is recommended, e.g.‘0.0.1’

最近做了一个支持Cocoapods的开源项目TCTitleLoading,总结了一下相关步骤。

1. 创建项目并提交到Github

创建你的项目并提交到github，记下代码地址备用，如：https://github.com/TravelC/TCTitleLoading.git

2. 创建Cocoapods使用的分支

创建一个供Cocoapods使用的分支，建议以版本号命名，如‘0.0.1’

开源了自己写的一个在导航栏标题下方的Loading，可自定义颜色及设置哪些页面不需要Loading。代码请见TCTitleLoading

TCTitleLoading

This is a loading in the bottom of navigation bar title area.
This project is inspired by XHLoadingNavigationItemTitleView

话不多说，上代码：

NSString *test=@"2015/11/12;*1-年2+3年月"; 
NSString *newString = [[test componentsSeparatedByCharactersInSet: [[NSCharacterSet decimalDigitCharacterSet] invertedSet]] componentsJoinedByString:@""]; 
NSLog(@"%@", newString);
