AVAudioSession.mm:1177:-[AVAudioSession setActive:withOptions:error:]: Deactivating an audio session that has running I/O. All I/O should be stopped or paused prior to deactivating the audio session.

解决方法

新建一个AVAudioSession的扩展类SXAudioSession

.h文件

#import  
@interface AVAudioSession (SXAudioSession)
@end

.m文件

#import "AVAudioSession+SXAudioSession.h"

@implementation AVAudioSession (SXAudioSession)

- (BOOL)setActive:(BOOL)active withOptions:(AVAudioSessionSetActiveOptions)options error:(NSError * _Nullable __autoreleasing *)outError
{
    return YES; //默认是 NO，修改成 YES
}
@end
