本文实例为大家分享了ios获取本地音频文件的具体代码，供大家参考，具体内容如下
获取本地音频文件地址：
我要评论
nsstring *songsdirectory=music_file_all;//沙盒地址
nsbundle *songbundle=[nsbundle bundlewithpath:songsdirectory];
nsstring *bundlepath=[songbundle resourcepath];
nsarray *arrmp3=[nsbundle pathsforresourcesoftype:@"mp3" indirectory:bundlepath];
for (nsstring *filepath in arrmp3) {
[self.wmp3url addobject:filepath];
}
解析音频文件属性：
-(void)mdefineupcontrol{
nsstring *filepath = [self.wmp3url objectatindex: 0 ];//随便取一个，说明
//文件管理，取得文件属性
nsfilemanager *fm = [nsfilemanager defaultmanager];
nsdictionary *dictatt = [fm attributesofitematpath:filepath error:nil];
//取得音频数据
nsurl *fileurl=[nsurl fileurlwithpath:filepath];
avurlasset *mp3asset=[avurlasset urlassetwithurl:fileurl options:nil];
nsstring *singer;//歌手
nsstring *song;//歌曲名
uiimage *image;//图片
nsstring *albumname;//专辑名
nsstring *filesize;//文件大小
nsstring *voicestyle;//音质类型
nsstring *filestyle;//文件类型
nsstring *creatdate;//创建日期
nsstring *savepath; //存储路径
for (nsstring *format in [mp3asset availablemetadataformats]) {
for (avmetadataitem *metadataitem in [mp3asset metadataforformat:format]) {
if([metadataitem.commonkey isequaltostring:@"title"]){
song = (nsstring *)metadataitem.value;//歌曲名
}else if ([metadataitem.commonkey isequaltostring:@"artist"]){
singer = (nsstring *)metadataitem.value;//歌手
}
// 专辑名称
else if ([metadataitem.commonkey isequaltostring:@"albumname"])
{
albumname = (nsstring *)metadataitem.value;
}else if ([metadataitem.commonkey isequaltostring:@"artwork"]) {
nsdictionary *dict=(nsdictionary *)metadataitem.value;
nsdata *data=[dict objectforkey:@"data"];
image=[uiimage imagewithdata:data];//图片
}
}
}
savepath = filepath;
float tempflo = [[dictatt objectforkey:@"nsfilesize"] floatvalue]/(1024*1024);
filesize = [nsstring stringwithformat:@"%.2fmb",[[dictatt objectforkey:@"nsfilesize"] floatvalue]/(1024*1024)];
nsstring *tempstrr = [nsstring stringwithformat:@"%@", [dictatt objectforkey:@"nsfilecreationdate"]] ;
creatdate = [tempstrr substringtoindex:19];
filestyle = [filepath substringfromindex:[filepath length]-3];
if(tempflo <= 2){
voicestyle = @"普通";
}else if(tempflo > 2 && tempflo <= 5){
voicestyle = @"良好";
}else if(tempflo > 5 && tempflo < 10){
voicestyle = @"标准";
}else if(tempflo > 10){
voicestyle = @"高清";
}
nsarray *temparr = [[nsarray alloc] initwithobjects:@"歌手:",@"歌曲名称:",@"专辑名称:",@"文件大小:",@"音质类型:",@"文件格式:",@"创建日期:",@"保存路径:", nil nil];
nsarray *temparrinfo = [[nsarray alloc] initwithobjects:singer,song,albumname,filesize,voicestyle,filestyle,creatdate,savepath, nil nil];
for(int i = 0;i < [temparr count]; i ++){
nsstring *strtitle = [temparr objectatindex:i];
uilabel *titlelab = [[uilabel alloc] initwithframe:cgrectmake(5, 5+i*30, 16*[strtitle length], 25)];
[titlelab settext:strtitle];
[titlelab settextcolor:[washaredfontstyle mgetsharedfontcolor]];
[titlelab setfont:[uifont systemfontofsize:16]];
[self.winfosv addsubview:titlelab];
nsstring *strinfo = [temparrinfo objectatindex:i];
uilabel *infolab = [[uilabel alloc] initwithframe:cgrectmake(titlelab.frame.origin.x+titlelab.bounds.size.width+5, 5+i*30, self.view.bounds.size.width-(titlelab.frame.origin.x+titlelab.bounds.size.width+5)-5, 25)];
[infolab settext:strinfo];
[infolab settextcolor:[washaredfontstyle mgetsharedfontcolor]];
[infolab setfont:[uifont systemfontofsize:16]];
[self.winfosv addsubview:infolab];
if(i == [temparr count]-1){
[infolab setframe:cgrectmake(titlelab.frame.origin.x+titlelab.bounds.size.width+5, 5+i*30, self.view.bounds.size.width-(titlelab.frame.origin.x+titlelab.bounds.size.width+5)-5, 30*4)];
[infolab setlinebreakmode:nslinebreakbywordwrapping];
[infolab setfont:[uifont systemfontofsize:12]];
[infolab setnumberoflines:0];
}
[self.winfosv setcontentsize:cgsizemake(self.view.bounds.size.width, i*45)];
}
}
