libz.1.2.3.dylib not found in iOS5, XCode 4.2

It seems that libz.1.2.3.dylib is not included in iOS5 sdk. Here is simple method to fix this:

1. Open your project in XCode 4.2

2. Remove libz.1.2.3.dylib from framework

3. Add new framework libz.1.2.5

4. Run you app

It works fine. At least for me šŸ˜‰

    • Blenglish should step aside in the Clutha elrceotate. It is plain to see that he can’t handle the rigours of a Ministerial post, and his inability to counter the machinations of Brash’s ACT coup, clearly display his inability to even be viable against a worthy political opponent, all mean that he should just retire from politics, and go back to fiddling with what ever it is he fiddles with up in Karori, now that he isn’t around sheep any-more.

  2. Hi Muzammil, i am using Flash Builder 4.6 to develop iphone app on windows platform so i want your suggestion that is it right to do this or not and what kind of limitations in this method.

    • Thanks, this helped me. Pretty new to iOS dpemloveent and XCode in general.FYI, this failed for me until I enabled Always Search User Paths . This might be obvious for people used to XCode etc but as a settled C#/Visual Studio guy, wasn’t aware of this myself, so this may help anyone who can’t quite get this working.Cheers,Alex

    • Ok i admit, I am noob but I just wanted to know. When we ilsnatl this kernal (vanilla doesn’t work for me and I have to run 10.4 sigh) where do i place the package before activation? DO i place it on my desktop or do i place it in the root directory through Finder? I tried it before and i do not think it ilsnatled it properly. I am able to use my laptop with 10.6.5 but my current kernel is 10.4 and I want to upgrade that to this one. My laptop is the MSI GT725-212US. No one seems to have been able to get this going on SL but I have it running (although at 1024 768 because of my ATI mobility HD Radeon 4850). So please let me know and thank you for your boot CD as that allowed me to ilsnatl my retail DVD when the other boot cds failed.
