swift知识点--反射

反射创建对象和方法

class TestSW: NSObject {

override required init() {

print("init333333")

}

@objc func test(){

print("000")

}

@objc func test11(from:String){

print("111")

}

}

反射方法：

//反射创建对象

let module = Bundle.main.infoDictionary!["CFBundleExecutable"] as! String

let sw = NSClassFromString(module + ".TestSW") as! TestSW.Type;

let testSWModel = sw.init() //必须含有init方法

//被反射的方法需要在方法前面添加 @objc 修饰,可用以下方法反射

let methodSelector = NSSelectorFromString("test")

// let methodSelector = #selector(TestSW.test11(from:))

// let methodSelector = NSSelectorFromString("test11From:" )

testSWModel.perform(methodSelector)
