Swift 获取属性数组

//创建数组的类方法

class func propertList() ->Array{

 var count:UInt32 = 0

 let arr = NSMutableArray()

 //获取模型属性, 返回值是所有属性的数组

let list:UnsafeMutablePointer<objc_property_t>! = class_copyPropertyList(self, &count)

for i in 0..count{

//获取属性

let property:objc_property_t = list[Int(i)];

//获取属性名称

let cName = property_getName(property)

// UnsafePointer转成字符串

let name = UnsafeRawPointer(cName)

 arr.add(name) 

 } 

 //释放属性组

 free(list)

 return arr.copy() as! Array<Any>

}
