IPhone: static method versus sharedManager in Objective-C

Question

I have a bunch of functions that return the commonly used UIView in my application, for example.

+ (UIView *) getLikeRow:(CGRect) frame ofType:(LikeType) type

So far I have used static methods for this, but recently I also noticed a concept sharedManager. Now I am wondering if I prefer to use sharedManager for this.

What are the differences and advantages / disadvantages of using static methods or instance methods of SingleMan? sharedManager?

You use the singleton / shared-managed template when it is important that only one instance of the class is available at any time.
