LDCopying

LDCopying is a category of NSObject. It provides an infinite layer deep copy of objects, include of custom objects and collection objects.

Installation

LDCopying is available through CocoaPods. To install it, simply add the following line to your Podfile:

pod 'LDCopying'

Useage

Import the header file.

#import <NSObject+LDCopying.h>

Use LDDeepCopy instead of copy or mutableCopy.

[obj LDDeepCopy]

The obj must be key-value coding compliant.

If you want to customize the copy process for a class, you can override the LDDeepCopy method of that class. For example:

@implementation Car
- (id)LDDeepCopy {
    Car *car = [[Car alloc]init];
    car.name = [self.name stringByAppendingString:@"_Copy"];
    return car;
}
@end
