关于第26条
一个项目中类一般会有成百上千个,这样貌似会增加app启动时间吧
假如交换了一个UITableView和一个UIView中的方法,分别需要在这两个类的Extension中写awake函数,UIView是UITableView的父类,静态方法又不允许重写,就会有问题,有什么好的解决办法吗,想尝试用泛型去约束也没搞出来。(貌似在一个NSObject的Extension中实现协议的这个默认方法再添加@objc重写可以实现,但是感觉这样不优雅。)
如题
我看你代码中习惯这样定义一个静态方法(11.华丽的tableView中第二条)
enum AnimationFactory {
static func makeFade() {
//TODO:
}
}
一般我这样写都是声明为struct类型,不知道声明成enum类型是出于性能考虑还是个人喜好?
