I'm facing a issue when try to build the app in xcode.
It says that UnityZIP is not a arm7 architecture.

I'm using Unity 5.0.3 and I get this error in Xcode after uilding the app:

I found out that disabling ARC form the files ZipArchive and UnityZipFile by using the flag -fno-objc-arc solves the problem. That said, is it possible to not have the build error while keeping ARC enabled?

Thanks

Since adding this library, whilst I can play it in Unity and even build from Unity (for Android), I seem to get errors in Cloud Build, stating:

error CS0103: The name `ZipUtil' does not exist in the current context

All the Asset files are in my project, along with the PluginsCode directory. As mentioned, it works fine running via Unity on Windows and if I build for Android myself.

Any idea whats going on?

could you attach ZipArchive.h? The .mm file included .h file but it cannot found .h file.

I tried the following code with ur unzipper.
But it doesn't work on Android 2.3
string filepath = "jar:file://" + Application.dataPath + "!/assets/" + "/TEST.zip";
pathtoExtract = filepath;
pathtoExport = Application.persistentDataPath;
try{
ZipUtil.Unzip(pathtoExtract, pathtoExport);
}
catch (Exception err)
{
text.text = err.ToString();
}

It says the same for the other architectures as well. Not able to build for iOS atm.

Hello,
I have to build my project using the xcodebuild command line, and I have some trouble with linking the UnityZip files.
Do you have an idea how I can achieve this?
Thanks by advance,

I am new to ios and xcode.

When I build the project to xcode, it always give me error, how to add the ZipArchive to xcode project, add the whole folder? and waht about the references?

Thanks

Hello, I have used it, but I don't know how to do it with multiple zip file?

When I try to build the generated project from Unity in Xcode, I get undefined symbols errors when linking. The symbols are:
_zip
_unzip
_addZipFile

I've tried adding the folder ZipArchive from PluginsCode, as instructed in README.md, at the Classes folder of my Xcode project, and also at Libraries/Plugins/iOS folder, but get the same errors.

What can I do to succeed the build?

hello

Not sure if I've done something weong, but when I make a build and try to use the zipping, I get this:
(Filename: C:/buildslave/unity/build/artifacts/generated/common/runtime/UnityEngineDebugBindings.gen.cpp Line: 65)

ArgumentException: Encoding name 'IBM437' not supported

Have you tested the project using the new IL2CPP compiler for iOS?
Builds using UnityZip, seem to always fail.

Here's a bug on Unity's Issue Tracker mentioned by someone else:
http://issuetracker.unity3d.com/issues/il2cpp-regression-projects-with-ionic-zlib-assembly-fail-to-build-in-4-dot-6-2p1

I am testing in 4.6.2P1 and seeing the same issues.

Thanks!

I get this error when I try unzipping a zipped file

The description mentions it works on mac, doesn't it!? Could any explain the issue? Thanks in advance

If you build with the unizip plugin, you will get this error.
What should I do
