电子商务网站开发主要实现功能,对外贸营销型网站建设的几点建议,idc数据中心,友情链接也称为项目中有面部认证、声纹认证#xff0c;服务器端要求上传wav格式的音频#xff0c;所以写了这样一个小demo。
刚刚开始写博客还不知道怎么上传代码#xff0c;就复制了#xff0c;嘻嘻 DotimeManage.h class DotimeManage;

} end 在需要录制音频的界面调用这两个文件
录制音频的按钮有两个响应事件代码如下 [recordingBtn addTarget:self action:selector(buttonSayBegin) forControlEvents:UIControlEventTouchDown]; [recordingBtn addTarget:self action:selector(buttonSayEnd) forControlEvents:UIControlEventTouchUpInside]; - (void)buttonSayBegin
{ [self stopAudio]; [[Recorder shareRecorder]startRecord]; } - (void)buttonSayEnd
{ [[Recorder shareRecorder]stopRecord]; [self stopAudio]; // [StateLable setText:播放录音文件中。。]; NSString * string [Recorder shareRecorder].filePath; [self playAudio:string]; } //播放 - (void)playAudio:(NSString *)path { NSURL *url [NSURL URLWithString:path]; NSError *err nil; audioPalyer [[AVAudioPlayer alloc] initWithContentsOfURL:url error:err]; audioPalyer.delegate self; [audioPalyer prepareToPlay]; [audioPalyer play]; } //停止播放 - (void)stopAudio { if (audioPalyer) { [audioPalyer stop]; audioPalyer nil; } } - (void)playing { if([audioPalyer isPlaying]) { [audioPalyer pause]; } else { [audioPalyer play]; } } #pragma mark -AVAudio 代理方法- - (void)audioPlayerDidFinishPlaying:(AVAudioPlayer *)player successfully:(BOOL)flag { } OK 问题解决
