What's the difference between using a plus or minus in Objective-C?

For example, most of the time code starts -(void)somethingSomethingelse, but sometimes it will be +(void)somethingSomethingelse

Thanks!

member and public functions respectively.

Such that

id object = [[NSObject alloc] init];
+ (id)alloc;
- (id)init;

Where NSObject is a Class and id is an object

If you have ever used C++, a + is equivalent to static
