将 doc 文件压缩到 ios 并保存到 document 目录

Question

我想将 doc 文件保存到文档目录中的 zip 文件中，当用户选择时，他们可以将其附加到电子邮件中。我已经创建了 zip 文件，但是当我想再次打开它时，它创建了一个 zip 文件，zip.cpgz 而不是 testing.zip。

这是我创建 zip 文件的代码

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];

NSArray *filePathsArray = [[NSFileManager defaultManager] subpathsOfDirectoryAtPath:documentsDirectory  error:nil];

int index =0;
for (NSString *item in filePathsArray){
    if ([[item pathExtension] isEqualToString:@"doc"])
    {
       NSString *filePath = [documentsDirectory stringByAppendingPathComponent:[filePathsArray objectAtIndex:index]];
        //NSString *FileName=[stringPath1 stringByAppendingPathComponent:@"Console.doc"];

        NSString *stringPath=[documentsDirectory stringByAppendingPathComponent:[@"testing" stringByAppendingFormat:@".zip"]];

        ZipFile *zipFile = [[ZipFile alloc]initWithFileName:stringPath mode:ZipFileModeCreate];


        ZipWriteStream *stream= [zipFile writeFileInZipWithName:@"doc" compressionLevel:ZipCompressionLevelBest];
        NSData *data = [NSData dataWithContentsOfFile:filePath];
        [stream writeData:data];
        [stream finishedWriting];

    }
}

你必须使用ssziparchive

用于压缩和解压缩 iOS

文件的实用程序 class

提供的示例：-

// Unzipping
NSString *zipPath = @"path_to_your_zip_file";
NSString *destinationPath = @"path_to_the_folder_where_you_want_it_unzipped";
[SSZipArchive unzipFileAtPath:zipPath toDestination:destinationPath];


    // Zipping
    NSString *zippedPath = @"path_where_you_want_the_file_created";
    NSArray *inputPaths = [NSArray arrayWithObjects:
                           [[NSBundle mainBundle] pathForResource:@"photo1" ofType:@"jpg"],
                           [[NSBundle mainBundle] pathForResource:@"photo2" ofType:@"jpg"]
                           nil];
    [SSZipArchive createZipFileAtPath:zippedPath withFilesAtPaths:inputPaths];
