[!]Unable to add a source with url `https://github.com/CocoaPods/Specs.git` named `master-1`.  You can try adding it manually in `~/.cocoapods/repos` or via `pod repo add`.是由于我装了多个Xcode导致路径变了，

解决：hwjdeMacBook-Pro:IJiaXiao_JiaoLian hwj$ sudo xcode-select -switch /Applications/Xcode6.3.1/Xcode.app

3.代理用逗号链接继承的类

class RecordViewController: UIViewController,LFLiveSessionDelegate{

4.appdelegate

dict[NSLocalizedDescriptionKey]= "Failed to initialize the application's saved data" as AnyObject?

5.detailView

5.实现代理方法

extension RecordViewController : LFLiveSessionDelegate {

/*实现协议所规定的内容*/

}

解决:删除masterView

9.跳转隐藏NavigationBar

10.使用第三方框架或者pod,需要桥接文件kaixin01/kaixin01-Bridging-Header.h还有拖入.h和.m文件到项目中

11.枚举元素的限制不能被引用作为实例成员swift?????????????????
