一、類名轉(zhuǎn)字符串

class func swiftStringFromClass(cls : AnyClass) -> String{

? ? ? ?let str : String = NSStringFromClass(cls)

? ? ? ?return str

｝

二、字符串轉(zhuǎn)類名

1.轉(zhuǎn)類名

class func swiftClassFromString(className: String) -> AnyClass! {

? ? ? ? ?let cls : AnyClass? = NSClassFromString(className)

? ? ? ? assert(cls != nil, "class not found,please check classname")

? ? ? ? return cls

｝

2.實(shí)例化，以實(shí)例化UIViewController為例

let vcClass : AnyClass? = NSClassFromString(appName.ClassName)

guard let VC = vcClass as? UIViewController.Type ? else {

return

}

let vc = VC.init()
