UIWebView播放音乐无声音

1.导入AVFoundation.framework

#import 

2.在- (void)viewDidLoad{}里添加一下代码:

AVAudioSession *audioSession = [AVAudioSession sharedInstance];
BOOL flag;
NSError *setCategoryError = nil;
flag = [audioSession setCategory:AVAudioSessionCategoryPlayback error:&setCategoryError];

3.重新运行，大功告成
