迅速膨胀的[UInt8]无法用miniz lib压缩

[英]Swift inflated [UInt8] fails to deflate with miniz lib

I have an iOS app where I use DeflateSwift to deflate a byte array ( [UInt8] ). 我有一个iOS应用程序，使用DeflateSwift压缩字节数组（ [UInt8] ）。 When I try to inflate this data using the miniz library it is not working. 当我尝试使用miniz库向这些数据充气时，它无法正常工作。 This is executed in another platform. 这是在另一个平台上执行的。 The DeflateSwift is a very simple wrapper around the zlib library which have been around for ages. DeflateSwift是围绕zlib库的非常简单的包装，这种库已经存在了很长时间。

I have tried to set different value on windowsBits as well as compressionLevel when doing the inflate in the app. 在应用中进行充气时，我尝试在windowsBits和compressionLevel上设置不同的值。 This has not solved the problem. 这还没有解决问题。 The miniz use windowsBits = 15 by default which is the default setting for DeflateSwift as well. 最小默认情况下使用windowsBits = 15 ，这也是DeflateSwift的默认设置。

According to the documentation miniz should be 100% compatible with zlib, which does not seems to be the case. 根据文档， miniz应该与zlib 100％兼容，但事实并非如此。

Has anybody else encountered similar problems? 还有其他人遇到过类似的问题吗？ Are there any more settings than windowsBits & compressionLevel that I could fiddle with? 除了windowsBits和compressionLevel ，还有什么我可以摆弄的设置吗？

As it turns out I did not get the DeflateSwift classes to work with the miniz library. 事实证明，我没有让DeflateSwift类与miniz库一起使用。 However the NSData+Compression found in CocoaGit works for this. 但是，在CocoaGit中找到的NSData+Compression可以解决此问题。
