Question

由于加密出口法规，可以使用此库吗？或者我可以使用哪一个来压缩/解压缩文件？

Answer 1

我不知道是否允许SSZipArchive在分布式应用中使用，但我使用的库是Objective-Zip。

它可以轻松集成到任何项目中。

压缩的示例代码：

// create a zip file for writing
ZipFile *zipFile= [[ZipFile alloc] initWithFileName:pathOfTheFileToBeZipped mode:ZipFileModeCreate];

// Add a file, write to its stream and close it
ZipWriteStream *stream1= [zipFile writeFileInZipWithName:@"abc.txt" fileDate:[NSDate dateWithTimeIntervalSinceNow:-86400.0] compressionLevel:ZipCompressionLevelBest];
NSString *text= @"abc";
[stream1 writeData:[text dataUsingEncoding:NSUTF8StringEncoding]];
[stream1 finishedWriting];

// Add another file, write to its stream and close it
ZipWriteStream *stream2= [zipFile writeFileInZipWithName:@"x/y/z/xyz.txt" compressionLevel:ZipCompressionLevelNone];
NSString *text2= @"XYZ";
[stream2 writeData:[text2 dataUsingEncoding:NSUTF8StringEncoding]];
[stream2 finishedWriting];

// Close the zip file
[zipFile close];

解压缩的示例代码：

// open the zip file for reading
ZipFile *unzipFile = [[ZipFile alloc] initWithFileName:pathOfTheFileToBeUnzipped mode:ZipFileModeUnzip];

// retrieve the info of the files inside
NSArray *infos= [unzipFile listFileInZipInfos];

// iterate over files
for (FileInZipInfo *info in infos) {        
    // locate the file in the zip
    [unzipFile locateFileInZip:info.name];

    // expand the file in memory
    ZipReadStream *read= [unzipFile readCurrentFileInZip];
    NSData *data = [read readDataOfLength:info.length];
    [read finishedReading];

    // construct the folder/file path structure
    NSString *unzipPathFilename = [unzipPath stringByAppendingPathComponent:info.name];
    NSString *unzipPathFoldername = [[unzipPathFilename stringByDeletingLastPathComponent] copy];
    NSError *errorw;

    // write the unzipped files, with some consistency checks
    NSRange range = [unzipPathFoldername rangeOfString:@"__MACOSX"];

    if (range.location == NSNotFound) {
        if ([fileManager createDirectoryAtPath:unzipPathFoldername withIntermediateDirectories:YES attributes:nil error:&errorw]) {
            if (![[unzipPathFilename pathExtension] isEqualToString:@""] && ![[[unzipPathFilename lastPathComponent] substringToIndex:1] isEqualToString:@"." ]) {
                [data writeToFile:unzipPathFilename atomically:NO];
            }
        }
        else {
            NSLog(@"Directory Fail: %@", errorw);
        }
    }
}

// close the zip file
[unzipFile close];

Answer 2

实际上，您可以在iOS应用程序中加密。您只需向NSA提交申请，您的应用程序具有哪种加密功能。通常在30分钟内响应您的注册号码。它是自动或半自动的。他们只收集有关开发人员的信息

然后注册为iOS开发人员更简单。

我的意见： -

如果您不在ZIP库中使用加密，那么您应该提交任何申请。链接器将在优化后删除该代码。该代码未使用。但是，如果你使用iOS附带的加密，那么你应该申请。例如如果UIWebView打开https：// URL（例如Facebook），但如果您使用UIWebView打开非安全页面，则不应该应用。

允许在App Store中使用ssziparchive库吗？
