Swift 5 动态获取一个类的属性，方法，和变量

1、获取一个类的所有属性

func getAllPropertys(view: Any?) -> [String] {
    var result = [String]()
    let count = UnsafeMutablePointer<UInt32>.allocate(capacity: 0)
    let buff = class_copyPropertyList(object_getClass(view), count)
    let countInt = Int(count[0])
    for i in 0..<countInt {
        if let temp = buff?[i] {
            let cname = property_getName(temp)
            let proper = String(cString: cname)
            result.append(proper)
        }
    }
    return result
}

2、获取一个类的成员变量

func getAllIvarList(view: Any?) -> [String] {
    var result = [String]()
    let count = UnsafeMutablePointer<UInt32>.allocate(capacity: 0)
    let buff = class_copyIvarList(object_getClass(view), count)
    let countInt = Int(count[0])
    for i in 0..<countInt {
        if let temp = buff?[i],let cname = ivar_getName(temp) {
            let proper = String(cString: cname)
            result.append(proper)
        }
    }
    return result
}
