Answer 1

Make your custom class conform to NSCoding protocol and then serialize it.

For more info, visit the Apple documentation

Also, this link will also help you. As suggested in this link, archive your custom class to NSData and serialize that as provided in the Apple documentation.

Edit Make your Animal.m as follows:

#import "Animal.h"

@implementation Animal
@synthesize name, description, imageURL;

-(id)initWithName:(NSString *)n description:(NSString *)d url:(NSString *)u {
    self = [super init];
    if( self )
    {
       self.name = n;
       self.description = d;
       self.imageURL = u;
    }
    return self;
}

- (id)initWithCoder:(NSCoder *)aDecoder
{
    self = [super init];
    if( self )
    {
        self.name = [aDecoder decodeObjectForKey:@"name"];
        self.description = [aDecoder decodeObjectForKey:@"description"];
        self.imageURL = [aDecoder decodeObjectForKey:@"imageURL"];
    }
    return self;
}

- (void)encodeWithCoder:(NSCoder *)encoder
{
    [encoder encodeObject:name forKey:@"name"];
    [encoder encodeObject:description forKey:@"description"];
    [encoder encodeObject:imageURL forKey:@"imageURL"];
}
