从NSDatePicker添加声音以在播放时播放 [英] Add sound to play at time from NSDatePicker

问题描述

我正在创建一个项目，该项目要求用户能够设置在特定时间播放的声音，而我目前正在通过本地通知进行操作.我想将其更改为使用AVAudioPlayer，我想知道什么是最好的方法?

I'm creating a project which requires the user to be able to set a sound to play at a specific time and I'm currently doing that with local notification. I would like to change that to use AVAudioPlayer, and I was wondering, what would be the best approach?

此刻我得到的对象是NSDatePicker和stringFromDate字符串.我的目的是创建一个警报，以便用户可以使用NSDatePicker设置时间，然后声音会消失.

The objects I've got at the moment are a NSDatePicker and a stringFromDate string. My aim is to create an alarm so that the user can set a time using the NSDatePicker and at that time the sound will go off.

推荐答案

请使用Global变量或Class变量来播放警报.

Please use Global variable or Class variable to play the alarm.

@property AVAudioPlayer * player;

......

_player = [AVAudioPlayer alloc]...
[_player play];

对您的项目来说效果很好.

It'll works fine for your project.
