Inspired by RestKit. A very simple objective-c framework that maps a JSON response from NSDictionary or NSArray to NSObject subclasses for iOS.
Suppose this is a JSON User object response represented in NSDictionary after parsing
{
"create_date" = "1970-01-01T00:00:00+0000";
"p_age" = 30;
"p_childs" = (
Mary,
James
);
"p_name" = Bob;
"p_title" = Manager;
}
Get ready with your JSON use [NSObject objectFromJSONObject:json mapping:mapping] to convert.
...
NSDictionary *json = <Parsed JSON response from above>;
//
// Use +[NSObject objectFromJSONObject:mapping:] to convert
// the NSDictionary into your JTUserTest object
//
JTUserTest *user = [JTUserTest objectFromJSONObject:json mapping:mapping];
...
Define necessary mappings, from a dictionary key to a property keyPath.
NSDictionary *mapping = [NSDictionary dictionaryWithObjectsAndKeys:
@"name", @"p_name",
@"title", @"p_title",
@"age", @"p_age",
@"childs", @"p_childs",
[NSDate mappingWithKey:@"createDate"
dateFormatString:@"yyyy-MM-dd'T'hh:mm:ssZ"], @"create_date",
nil];
Of course you need to define your own User object with corresponding @synthesize properties, and thats all for what you need.
// JTUserTest.h
@interface JTUserTest : NSObject
@property (nonatomic, copy) NSString *name;
@property (nonatomic, copy) NSString *title;
@property (nonatomic, copy) NSNumber *age;
@property (nonatomic, retain) NSDate *createDate;
@property (nonatomic, retain) NSArray *childs;
@end
// JTUserTest.m
#import "JTUserTest.h"
@implementation JTUserTest
@synthesize name, title, age;
@synthesize createDate;
@synthesize childs;
@end
For more detailed usage, see JTObjectMappingTests.m, will be adding more detailed description soon.
