在ios中压缩doc文件并将其保存到文档目录

Question

I would like to save a doc file into a zip file in the document directory and when the user chooses they can attach it in an email. I have created the zip file but when I want to open it again it creates a zipfile, zip.cpgz instead of testing.zip .

Here is my code for creating the zip file

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];

    }
}

You must use ssziparchive

An Utility class for zipping and unzipping files for iOS

Example provided:-

// 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];
