iOS Cell Registration & Reusing with Swift Protocol Extensions and Generics

A common task when developing iOS apps is to register custom cell subclasses for both UITableView and UICollectionView. Well, that is if you don’t use Storyboards, of course.

Both UITableView and UICollectionView offer a similar API to register custom cell classes:

public func registerClass(cellClass: AnyClass?, forCellWithReuseIdentifier identifier: String)
public func registerNib(nib: UINib?, forCellWithReuseIdentifier identifier: String)

1.同一台电脑可以有2个git账号（不同网站的）

首先不同网站，当然可以使用同一个邮箱，比如我的github，gitlab，bitbucket的账号都是monkeysuzie[at]gmail.com 这时候不用担心密钥的问题，因为这些网站push pull 认证的唯一性的是邮箱 比如我的windows 上 2个账号一个gitlab 一个github （用的都是id_rsa）

host github
  hostname github.com
  Port 22

host gitlab.zjut.com
