Create JSONArray of JSONObjects using AFNetworking 2.0 in Objective-C - ios

Question

- The structure that I am trying to create is
[{'category_id': '3'}, {'category_id': '2'}, {'category_id': '1'}]
- I tried creating the same using NSMutableArray of NSMutableDictionary & the structure that i got back was:
<__NSArrayM 0x7c186080>(
{
"category_id" = 1;
},
{
"category_id" = 2;
},
{
"category_id" = 3;
}
)
- I am sending this to server over HTTPPost.
- But on the server the request is reaching as:
{(null)[][category_id]': ['1', '2', '3']}
Which is not in the desired format as i showed above in point 1.
- Can anyone please help me out create an JSONArray of JSONObjects, I would be really obliged.
The code that i used to create and send the request to server is:
-(void) getProductList:(NSString *)strToken andCatId:(NSArray *)arrCategory{
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
[manager.requestSerializer setValue:strToken forHTTPHeaderField:#"Authorization"];
manager.responseSerializer = [AFJSONResponseSerializer serializerWithReadingOptions:NSJSONReadingAllowFragments];
NSString *strSuffix = #"unfollow/productList/";
NSString *strUrl = [NSString stringWithFormat:#"%#%#",BASE_URL,strSuffix];
api_categoryProductList *currentObj = self;
[manager POST:strUrl parameters:arrCategory success:^(AFHTTPRequestOperation *operation, id responseObject) {
[currentObj httpOperationDidSuccess:oper
ation responseObject:responseObject];
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
[currentObj httpOperationDidFail:operation error:error];
}];
}

Try this:
NSMutableArray *array = [[NSMutableArray alloc] init];
NSNumber *id = [NSNumber numberWithInt:1];
for (int i = 0; i < 5; ++i) {
NSMutableDictionary *dict = [[NSMutableDictionary alloc] init];
[dict setObject:id forKey:#"category_id"];
[array addObject:dict];
}
Right now it has static id as 1. You can change it to whatever value you like.
