启用放在X code IOS禁用扬声器8.1同时呼吁

问题描述

我需要启用扬声器，而从应用程序调用。我可以成功地启用它，但我不能禁用它。

I need to enable speaker while calling from app. I can successfully enable it but I am not able to disable it.

我使用这个方法：

[[UIDevice currentDevice] setProximityMonitoringEnabled:NO];
NSLog(@"%d",enable);

UInt32 route;
route = enable ? kAudioSessionOverrideAudioRoute_Speaker :
kAudioSessionOverrideAudioRoute_None;

AudioSessionSetProperty (kAudioSessionProperty_OverrideAudioRoute,
                         sizeof(route), &route);

先谢谢了。

AudioSessionSetProperty是pcated德$ P $。

AudioSessionSetProperty is Deprecated.https://developer.apple.com/library/ios/documentation/audiotoolbox/reference/audiosessionservicesreference/index.html#//apple_ref/c/func/AudioSessionSetProperty

    - (void)setAudioOutputSpeaker:(BOOL)enabled
    {
    AVAudioSession *session =   [AVAudioSession sharedInstance];
    NSError *error;
    [session setCategory:AVAudioSessionCategoryPlayAndRecord error:&error];
    [session setMode:AVAudioSessionModeVoiceChat error:&error];
    if (enabled) // Enable speaker
        [session overrideOutputAudioPort:AVAudioSessionPortOverrideSpeaker error:&error];
    else // Disable speaker
        [session overrideOutputAudioPort:AVAudioSessionPortOverrideNone error:&error];
    [session setActive:YES error:&error];
    }
