Please do not post the same thing multiple times. The board software automatically flags certain posts as needing moderator attention. This happens the most often for new users. I'm pretty sure this is made clear at the time you attempt to post. Posting the same thing over and over again just makes that many more posts the moderators have to weed through later. This makes us sad. Don't make us sad. If your post/thread doesn't appear, just wait a while. Don't post it again. If it hasn't shown up by the next day, then you can try again. I normally go through posts in the mornings, and try to check a few times throughout the day, but I'm not here 24/7. There will typically be a significant delay before posts are approved. Just be patient.
LOL. I was reaching for the reply button to say EXACTLY the same thing.
That's what you're asking. Some indie devs at game jams make small, simple games with one developer over a weekend. Large production houses spend years with literally hundreds of people working full time on one game. To take a cinema analogy, do you want to make a 30-second YouTube video, or do you want to make the Lord of the Rings trilogy?
That is an extremely low-level function that is used by the "guts" of Cocoa to implement Objective C message passing. Why are you trying to call it directly?
Unless you really know what you are doing, you are way, way too far down in the innards of iOS, (over your head, in other words) and need to rethink what you are doing.
Are you an expert Cocoa developer with several years of experience? If the answer to that question is no, stop, forget you ever read about that method, and find another way to do what you are doing.
I've been programming in Cocoa for Mac and iOS nearly full time since early 2007. I've NEVER had occasion to call objc_msgSend directly.
