iOS － 遍历指定路径下的所有文件（不包括更下级文件）

  NSArray *firstSavePathArray=NSSearchPathForDirectoriesInDomains(NSLibraryDirectory,NSUserDomainMask,YES);
    for (NSString *path in firstSavePathArray) {
        NSLog(@"%@",path);
    }
    NSFileManager *fileManager = [NSFileManager defaultManager];
    NSError *error = nil;
    NSArray *fileList = [[NSArray alloc] init];
    fileList = [fileManager contentsOfDirectoryAtPath:firstSavePathArray[0] error:&error];
    NSLog(@"%@",fileList);
