Remove Image Cache

I am using AfNetworking version ~> 1.3.4, which is added by cocoaPods. And I can't upgrade to 2.0 because most of the methods are used in my Application.

AFImageCache (in UIImageView+AFNetworking) cannot be cleared when a new image with the same URL is used

I supposed to add the following method in "UIImageView+AFNetworking" Class for this . 

+ (void)clearCachedImages {
     [[[self class] af_sharedImageCache] removeAllObjects];
}

As because AFNetworking is in my cocoaPods. I am unable to add. Please help me how to add this method by category / Subclass?

EDIT:

I have tried the following

@class AFImageCache;

@interface SPUtility : NSObject
{

}
@end

@implementation SPUtility

+ (void)clearCachedImages {
    [[AFImageCache af_sharedImageCache] removeAllObjects]; //shows following error
}
@end

Error: No Known class method for selector 'af_sharedImageCache' 2. Receiver 'AFImageCache' for class message is a forward Declaration

Make a category for UIImageView as your af_sharedImageCache is in UIImageView (AFNetworking)

SPUtility.m

@interface UIImageView (MyMethods)
+ (NSCache *)af_sharedImageCache;
@end
//you don't have to implement method since it's already defined in UIImageView (AFNetworking)
//It's just for the happiness of the compiler



@implementation SPUtility

+ (void)clearCachedImages {
  [[UIImageView af_sharedImageCache] removeAllObjects];
}
@end
