I am using objective-c and trying to deserialize JSON into an array of a custom class called Blog. So the code below should generate three objects and add them to an array of objects. I've looked at this tutorial but still ran into issues.
The JSON structure looks like this:
{
"-KGN0p1I4YFI2YNOcbv3" : {
"BlogDomain" : "blg1",
"BlogName" : "n1"
},
"-KGN198bzC54opL47vUl" : {
"BlogDomain" : "blg2",
"BlogName" : "n2"
},
"-KGN66aqkhIxBAKTcFCx" : {
"BlogDomain" : "blg3",
"BlogName" : "n3"
}
}
any help would be appreciated.

Please try out the below code:
NSString* path = [[NSBundle mainBundle] pathForResource:#"JSON" ofType:#"json"];
NSString* jsonString = [[NSString alloc] initWithContentsOfFile:path encoding:NSUTF8StringEncoding error:nil];
NSData* jsonData = [jsonString dataUsingEncoding:NSUTF8StringEncoding];
NSError *error = nil;
NSDictionary *object = [NSJSONSerialization
JSONObjectWithData:jsonData
options:0
error:&error];
if(! error) {
NSMutableArray *array = [[NSMutableArray alloc] init];
for (NSString *dictionaryKey in object) {
Blog *oBlog = [[Blog alloc] init];
oBlog.blogDomain = [[object valueForKey:dictionaryKey] objectForKey:#"BlogDomain"];
oBlog.blogName = [[object valueForKey:dictionaryKey] objectForKey:#"BlogName"];
[array addObject:oBlog];
}
} else {
NSLog(#"Error in parsing JSON");
}
//Blog.h
#import <Foundation/Foundation.h>
#interface Blog : NSObject
#property (nonatomic, strong) NSString *blogDomain;
#property (nonatomic, strong) NSString *blogName;
#end
//Blog.m
#import "Blog.h"
#implementation Blog
#end
//JSON.json
{
"-KGN0p1I4YFI2YNOcbv3" : {
"BlogDomain" : "blg1",
"BlogName" : "n1"
},
"-KGN198bzC54opL47vUl" : {
"BlogDomain" : "blg2",
"BlogName" : "n2"
},
"-KGN66aqkhIxBAKTcFCx" : {
"BlogDomain" : "blg3",
"BlogName" : "n3"
}
}
