今天做了一个简例,用tableView实现excel冻结窗格功能 Demo:https://git.oschina.net/sunflowrs/FreezePanes.git
初始化Tableview 实现代理
1
|
class BasicTableView:UITableView,UITableViewDelegate,UITableViewDataSource |
声明变量时,数组和字典,最好设置成已知类型,避免惹麻烦

2
|
var titleArr:Array<String> = [] var listArr:Array<Dictionary<String,String>> = [] |
改写父类方法时要用override关键字

override func awakeFromNib() { super.awakeFromNib() self.delegate = self self.dataSource = self self.separatorStyle = UITableViewCellSeparatorStyle.none self.showsVerticalScrollIndicator = false } |
需要注意:避免爆红 , 一定要实现一下两种方法
