获取指定路径内的文件和文件夹

1.包含子路径

NSArray<NSString *> *subPaths = [manager subpathsAtPath:zipPath];

2.不包含子路径

- (NSString *)getFileName:(NSString *)zipPath {
    NSString *filename = @"";
    //文件操作对象
    NSFileManager *manager = [NSFileManager defaultManager];
    NSError *error = nil;
    //不包含子路径
    NSArray<NSString *> *subPaths = [manager contentsOfDirectoryAtPath:zipPath error:&error];
    
    for (NSString *s in subPaths) {
        if ([[s pathExtension] isEqualTo:@"zip"]) {//筛选出文件后缀名是zip的文件
            filename = [s lastPathComponent];
            break;
        }
    }
    return filename;
}
