得到iPhone当前系统的音量 [英] get current system volume level on iPhone

问题描述

有没有一种方法我可以在iPhone上？

当前系统的音量级别

我想也许有一种方法，使从一个 MPVolumeView 和获得的价值。

解决方案

  musicPlayer = [[MPMusicPlayerController iPodMusicPlayer]currentVolume = musicPlayer.volume;
 

这是现在pcated为iOS8.0，所以请尝试以下去$ P $

 ＃进口＆LT; AVFoundation / AVAudioSession.h＆GT;AVAudioSession * audioSession = [AVAudioSession sharedInstance];
CGFloat的体积= audioSession.outputVolume;
 

Is there a way I can get the current system volume level on the iPhone?

I'm thinking maybe there's a way to make an MPVolumeView and get the value from that.

解决方案

musicPlayer = [[MPMusicPlayerController iPodMusicPlayer];

currentVolume = musicPlayer.volume;

This is now deprecated as of iOS8.0 so try the following

#import <AVFoundation/AVAudioSession.h>

AVAudioSession *audioSession = [AVAudioSession sharedInstance];
CGFloat volume = audioSession.outputVolume;
