OC语言读取wav文件

用AudioServicesPlaySystemSound进行播轮逗放，代码如下：（wav文件名为end.wav）稿睁

SystemSoundID ph

id sndpath = [[NSBundle mainBundle]pathForResource:@"end" ofType:@"wav" inDirectory:@"/"腊敬卖]

CFURLRef baseUrl = (__bridge CFURLRef)[NSURL fileURLWithPath:sndpath]

AudioServicesCreateSystemSoundID(baseUrl, &ph)

AudioServicesPlaySystemSound(ph)

由于Xcode和MacBook pro经常自己更新，所以我的自己的APP不打算走本地代理了，准备写到本地json

1首先创建路径

//获取文件路径

NSString *filePath = [[NSBundle mainBundle] pathForResource:@"路径名称渣罩派"闷毁 ofType:@"json"]

2读取如贺data

//根据文件路径读取数据

NSData *data = [[NSData alloc] initWithContentsOfFile:filePath]

3data专程json

NSDictionary *dic = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingMutableContainers error:nil]

options的几种类型
