• swift系统学习控件篇:UITableView+UICollectionView


    工作之余,学习下swift大法.把自己的学习过程分享一下.当中的布局很乱,就表在意这些细节了.直接上代码:

    UITableView:

     2 //  ViewController.swift
     3 //  UItableView-swift

    14         super.viewDidLoad()
    15         //定义一个UITableView
    16             let mytableView = UITableView(frame: CGRectMake(0, 0, UIScreen.mainScreen().bounds.size.width, UIScreen.mainScreen().bounds.size.height), style: UITableViewStyle.Plain)
