“NSArray"没有名为“append"的成员 [英] "NSArray' does not have a member named 'append'

问题描述

我刚刚开始快速编码，我正在尝试学习教程.但似乎我关注的编码器可能有旧版本，或者我做错了什么.我正在尝试制作一个声音对象来制作音板.但是当我尝试使用 append 将声音文件添加到数组时，它说方法 append 不是 NSArray 的成员.有人能告诉我解决这个问题的正确方法是什么吗?！]1

解决方案

声明声音为

var 声音:[声音] = []

I just got into swift coding and I am trying to follow a tutorial. but it seems as if the coder I'm following may have an older version, or I am doing something wrong. I am trying to make a sound object to make a soundboard. but when i try to add the sound file to the array using append, it says that the method append is not a member of the NSArray. can someone tell me what is the right way to do solve this?!]1

解决方案

Declare sounds as

var sounds: [Sound] = []
