Question

i am storing my “custom button” in NSUserdefaults using the following code.But i am getting an error “[UIImage encodeWithCoder:]: unrecognized selector sent to instance” while converting the object to NSdata..here “custom button” is UIButton class. Anyone know why…? please help me.

 Custom_button *lock11 = (Custom_button*)[menu1 viewWithTag:100];
                 NSLog(@"opened lock1 ========= %@",lock11);
                 lock11.is_menu_lock_opened = YES; 

                 NSData *myEncodedObject = [NSKeyedArchiver archivedDataWithRootObject:lock11]; //[NSKeyedArchiver archivedDataWithRootObject:lock11];
                 [prefs setObject:myEncodedObject forKey:@"set1lock"];

Implement this method into your Custom_button Class

initWithCoder and encodeWithCoder for all object

-(id) initWithCoder: (NSCoder *)coder {

       self = [[CastInnerListData alloc] init];
       if (self != nil) {       
           self.object1 = [coder decodeObjectForKey:@"object1"];
           self.object2 = [coder decodeObjectForKey:@"object2"];    
    }
    return self;
}

-(void) encodeWithCoder: (NSCoder *)coder{

      [coder encodeObject:object1 forKey:@"object1"];
      [coder encodeObject:object2 forKey:@"object2"];
}
