//根据文件名来获取文件路径
- (NSString *)dataFilePath:(NSString *)sender {
    NSArray *path = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,
                NSUserDomainMask,
                YES);
    NSString *documentDirectory = [path objectAtIndex:0];
    return [documentDirectory stringByAppendingPathComponent:sender];
}

 

 

 

resource目录下

NSString *defaultDBPath = [[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:filename];

 

Cache目录下

NSArray *cache = NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES);
   NSString *cachePath = [cache objectAtIndex:0] ;

   NSString *voiceName = [cachePath stringByAppendingPathComponent:[sender stringByAppendingString:@".wav"]];
