一、类名转字符串
class func swiftStringFromClass(cls : AnyClass) -> String{
let str : String = NSStringFromClass(cls)
return str
｝
二、字符串转类名
1.转类名
class func swiftClassFromString(className: String) -> AnyClass! {
let cls : AnyClass? = NSClassFromString(className)
assert(cls != nil, "class not found,please check classname")
return cls
｝
2.实例化，以实例化UIViewController为例
let vcClass : AnyClass? = NSClassFromString(appName.ClassName)
guard let VC = vcClass as? UIViewController.Type else {
return
}
let vc = VC.init()
