Swift 通过运行时获取属性名列表

import UIKit

//必须要有@objcMembers修饰符，否则获取到的成员属性为0

@objcMembers

class Person: NSObject {

var name: String?

var age: Int = 0

var title: String?

class func propertyList() -> [String] {

var arr: [String] = []

var count: UInt32 = 0

let list = class_copyPropertyList(self, &count)

print("参数的长度为\(count)")

for i in 0..<Int(count) {

let pty = list?[i]

//得到C字符串

let cName = property_getName(pty!)

//将C字符串转化为String

let name = String(utf8String: cName)

arr.append(name!)

}

return arr

}

}
