Cocoa doesn't provide anything called abstract. We can create a class abstract which gets check only at runtime, compile time this is not checked.

@interface AbstractClass : NSObject
@end
@implementation AbstractClass
+ (id)alloc{
if (self == [AbstractClass class]) {
NSLog(@”Abstract Class cant be used”);
}
return [super alloc];
@end
