Getting name of the class from an instance

Question

I have the following problem: I get an instance of a class passed and want to know the name of the class of this instance. How to get this?

Answer 1

Just add a category:

NSObject+Extensions.h
- (NSString *)className;

NSObject+Extensions.m
- (NSString *)className {
    return NSStringFromClass(self.class);
}

Then use the following code:

NSString *className = [[SomeObject new] className];

or even:

NSString *className = SomeObject.new.className;

To use it anywhere add the category to YourProject.pch file.
