ZipKit and iPhone

Question

Hello,

I tried to use the ZipKit framework (http://bitbucket.org/kolpanic/zipkit/wiki/UsingZipKit) in the test application for iPad. I followed the "Traditional way" of the installation (as it is described on their page) with no success. Hope somebody can help me with it:

1/ I used hg to get sources
2/ I build the ZipKit project (Release build)
3/ After doing this there was created in the build folder the new ZipKit.framework folder
4/ I have created a new test project for the iPad 3.2 (XCode 3.2.4)
5/ I have drag&dropped the ZipKit.framework folder created in the step 3) into Frameworks section on my new test project
6/ In Targets section I have created new Copy File Build Phase and I drag&drop the ZipKit.Framework from Frameworks section to the new Copy Files folder.
7/ Then I build and run the project.

The project cannot be even started, it is being closed after I press the project icon - so I must do something terribly wrong. In the console output I can see the error - it is pretty clear what is missing, but I do not know what to do with that... Might be some XCode expert or someone, who used the ZipKit can help me - this must some really stupid mistake I am doing...

There is the console output:

dyld: Library not loaded: @rpath/Frameworks/ZipKit.framework/Versions/A/ZipKit
  Referenced from: /Users/sten/Library/Application Support/iPhone Simulator/3.2/Applications/3C51FC4F-0E85-48D2-BC68-D01ADD73DAE1/ZipExample.app/ZipExample
  Reason: image not found
Failed to launch simulated application: iPhone Simulator failed to find the process ID of com.yourcompany.ZipExample.

BTW - I have tried to run the ZipKit Touch example provided with the framework and it works perfectly...

Thanks a lot BR STeN

There is the screenshot of my test project - on the left side you can see the ZipKit.framework I drag&drop into my project:

Answer 1

You should go back and read it again.

The "traditional way" is not the right way to do this - Apple don't allow iOS applications with external frameworks like this - you want to link against the static library instead using the process described under "Static Library Target".

Answer 2

Hi,

I have tried also the "Better Way" as described here http://bitbucket.org/kolpanic/zipkit/wiki/UsingZipKit. I tried to follow all steps, but the description is not too 100% clear to me. Anyway I was able to build the project and call the following code copied from example provided in the ZipKit Touch demo application:

NSString *archivePath = [[NSBundle mainBundle] pathForResource:@"ZipKitTest" ofType:@"zip"];
ZKDataArchive *archive = [ZKDataArchive archiveWithArchivePath:archivePath];
[archive inflateAll];

Unfortunately it crashes in the 2nd line of the code with the following error:

2010-10-20 05:11:10.625 ZipExample[10123:207] *** -[NSCFString zk_precomposedUTF8Length]: unrecognized selector sent to instance 0xd1c4

Hope someone could figure out the problem.

Answer 3

I've updated the Using ZipKit page to make it clear which ZipKit target should be used for what type of product.

Answer 4

Is there a basic page which shows some simple code for inflating and deflating files and directories for ZipKit?

UPDATE: I figured this out but it was a scavenger hunt:

NSString *filePath = [userDocumentsDirectory stringByAppendingPathComponent:@"newFile.zip"];

ZKFileArchive *archive = [ZKFileArchive archiveWithArchivePath:filePath];
[archive deflateDirectory:exportDirectory relativeToPath:nil usingResourceFork:NO];
