Question

In my Application i got the data in MutableDictionary like this,

 ApproverDetails:(
    {
    "APPROVER_ID" = "5000";
    "APPROVER_USER_NAME" = "38400 user";
    "END_DATE" = "12/29/10";
    "START_DATE" = "12/14/10";
    "SUBSTITUTE_ID" = SUPERVISOR;
    "SUBSTITUTE_USER_NAME" = "ACCESS ONLY";
    },
    {
    "APPROVER_ID" = "6000";
    "APPROVER_USER_NAME" = "ACCESS ONLY";
    "END_DATE" = "12/31/10";
    "START_DATE" = "12/15/10";
    "SUBSTITUTE_ID" = SSEEMON;
    "SUBSTITUTE_USER_NAME" = "Sunil Seemon";
    },
    {
    "APPROVER_ID" = "7000";
    "APPROVER_USER_NAME" = mit;
    "END_DATE" = "11/22/10";
    "START_DATE" = "11/09/10";
    "SUBSTITUTE_ID" = 2000;
    "SUBSTITUTE_USER_NAME" = mitul;
   }
 )

From above dictionary i want bifurcate data by key “Approved_User_Name” starting with “ACC”

and get bifurcated data into other Array.

Please suggest me how can i do this?

Answer 1

Try this

NSMutableArray *bifurcateArray=[[NSMutableArray alloc]initWithArray:nil];
for (NSDictionary *temp in ApproverDetails) {
    NSString *string=[temp objectForKey:@"APPROVER_USER_NAME"];
    if ([string rangeOfString:@"ACC"].location!=NSNotFound && [string rangeOfString:@"ACC"].location==0 ) {
        [bifurcateArray addObject:temp];
    }
}
NSLog(@"bifurcated data : %@",bifurcateArray);
