How to use Class object in Objective C code

I have four screens that are exactly the same except they use four different classes. I thought I could reduce them to one by putting this property in my header:

@property Class *classType;

Then I could set the class and be done.

HOWEVER, when I try to use classType like the following:

NSArray *myArray = [classType allobjects];

I get the following: "Bad receiver type __unsafe_unretained Class *"

This really doesn't make much sense. The class method returns and NSArray. When I use the explicit class name there is no error and everything works fine.

I'm using xcode 4.5 with ARC.

Quick search on Google, even better in the runtime's headers:

typedef struct objc_class *Class;

The Class type is a pointer itself - you don't need an extra * sign when declaring the property.

Try using

@property Class classType;

Note the missing *. Class is like id, the pointer type is implied.
