It seems that you used the description method to convert an NSArray into a string and store that into the SQLite database. There is no reliable way to reconstruct the array/dictionary from the description string (see stackoverflow.com/a/16783704/1187415 for an unreliable method). You should store the dictionary in a different way, e.g. in JSON format. — Martin R

If the format is json (as your tags suggest) the easiest way is to use NSJSONSerialization

Using

+ (id)JSONObjectWithData:(NSData *)data options:(NSJSONReadingOptions)opt error:(NSError **)error

Will get you a foundation class object returned (NSArray, NSDictionary, depending on the json data)

it is not a json.it is a string value from sqlite db

@user2775424 then why do you use the json tag? Google "NSString parsing", it will tell you everything you need.

u want dict values from array..so

 dataArray =[NSMutableArray array];
    NSMutableDictionary *dic =[[NSMutableDictionary alloc]init];
    [dic setObject:@"SUE1291ST" forKey:@"studentId"];
    [dic setObject:@"Student123Sdfw" forKey:@"studentName"];

    [dataArray addObject:dic];

     dic =[[NSMutableDictionary alloc]init];
    [dic setObject:@"SUE13291ST" forKey:@"studentId"];
    [dic setObject:@"name123Sdfw" forKey:@"studentName"];

    [dataArray addObject:dic];

    NSLog(@"dataArray:%@",dataArray);

    for (NSDictionary *dic in dataArray) {

        NSLog(@"DICTIONARY IS:%@",dic);
    }
