Yeah, cheatsheets can definitely make things alot easier, if you're familiar with C/C++/Java you really shouldn't have any problems. While Objective-C definitely looks weird, it's got more in common with C/C++/and Java than it has differences.

Hi Patty,
When you create a static (or class) method it is not created when you make an object. It belongs to the class, and the same memory location in memory containing that class is used by all objects, and you can use it directly from the class without even creating an object.. like you can run it as [ClassName staticMethod] rather than [objectName staticMethod].

Non-static means that with every object you create that method a different method is created in memory, and you run them usinh [objectName staticMethod].

In Objective-C from what I understand technically the methods are always placed in static, but I mentioned it being similar to the word static, as that is the terminology used in C/C++/Java and the behavior of the +/- modifiers you see at the start of a method cause the behaviour to be similar.

Hope I didn’t confuse you more!

The proceeding “+” and “-” just means “static” and “non-static”?

What does that mean?

Keep up the good work! I’m waiting for the next tutorial
I’m familiar with c, c++ & Java but objective-c gave me a hard time the first time I saw it. With your video and cheatsheet everything seems much easier.

Thanks
