如何获得AVAudioPlayer输出到扬声器 [英] How to get AVAudioPlayer output to the speaker

问题描述

在<一看到我记录与AVAudioRecorder音频href=\"http://stackoverflow.com/questions/1010343/how-do-i-record-audio-on-iphone-with-avaudiorecorder/1011273#1011273\">http://stackoverflow.com/questions/1010343/how-do-i-record-audio-on-iphone-with-avaudiorecorder/1011273#1011273

然后我用AVAudioPlayer播放录音。然而，发出声音的听筒，而不是外放。我怎么会去重定向声音外放？

I then use AVAudioPlayer to play back the recording. However the sound is coming out of the ear speaker, not the loud speaker. How would I go about redirecting the sound to the loud speaker ?

TIA！

UInt32 sessionCategory = kAudioSessionCategory_MediaPlayback;
AudioSessionSetProperty(kAudioSessionProperty_AudioCategory, sizeof(sessionCategory), &sessionCategory);    
UInt32 audioRouteOverride = kAudioSessionOverrideAudioRoute_Speaker;
AudioSessionSetProperty (kAudioSessionProperty_OverrideAudioRoute,sizeof (audioRouteOverride),&audioRouteOverride);
