使用objective c创建一个目录来保存iphone上录制的文件

#import <Foundation/Foundation.h>

NSString *documentsPath = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES)[0];

NSString *recordingsPath = [documentsPath stringByAppendingPathComponent:@"Recordings"];
NSError *error;
[[NSFileManager defaultManager] createDirectoryAtPath:recordingsPath withIntermediateDirectories:YES attributes:nil error:&error];
if (error) {
    NSLog(@"创建目录失败：%@", error.localizedDescription);
} else {
    NSLog(@"目录创建成功");
}

NSString *filePath = [recordingsPath stringByAppendingPathComponent:@"recording.wav"];
NSURL *fileURL = [NSURL fileURLWithPath:filePath];
// 将录音文件保存到fileURL指定的路径
