Hi, Thanks, It works now I've fixed the warnings.
Cheers. ________________________________ From: Stamenkovic Florijan <flor...@mac.com> To: Joshua Garnham <joshua.garn...@yahoo.co.uk> Cc: cocoa-dev <cocoa-dev@lists.apple.com> Sent: Thursday, 1 October, 2009 13:32:20 Subject: Re: Deleting CalTasks through an Array. Hi Joshua, You're welcome, but you need to also learn some stuff on your own. 1. Browse the docs: NSArray does not have a contains: method, it has a containsObject: method. My mistake, but one that's easy to spot. 2. Check the method signatures for CalCalendar store. I believe I gave you the right ones (in which case your imports are somehow messed up). If I gave you the wrong ones, change them. Also please keep all communication *on* the list.
