Is there a guide or cheat sheet somewhere that I can reference all the syntax of objective c?

I'd also like to see cheat sheets that you might have liked or would have liked when you started dev-ing in objective c.

@synthesize wi开发者_开发百科ndow;
#pragma mark -
#pragma mark Application lifecycle
@implementation OpenAlTestingAppDelegate

PS. I've looked at this, and it seems to be out of date.

Yes there is. Here is one. It seems relatively comprehensive to me.

By the way, that was the top hit from Googling Objective-C cheat sheet.

Honestly when I was starting with Objective-C I found the wikipedia page on the subject to be a great help. I don't know if it covers all of the syntax or if it can be considered a "cheat sheet", but it certainly helped me get up to speed with the basics of the language and its syntax quickly.

The one at http://hyperpolyglot.org/c is nifty because it compares syntax for five different C-based languages: C, C++, Objective-C, Java, and C#. I think this one could actually be useful if you already know one or more of the languages listed and are just trying to pick up one of the others. It won't make you an expert overnight, but this and a couple nights at Holiday Inn Express could point you in the right direction.
