• my NSDictionary *finalResult print this result

• Actually there are only two records but from web service I am getting this type of result they cannot distinct because of unique imageurl.

• so how can i remove duplicate data set.The same user data are only differ from each other with key imageurl.

• I just want only single record of user does not matter which one(any one). So finally I will get only two record

Answer 1

It may be a webservice error. Best way is to contact web team or you can remove the duplicates by using below way

You can check the duplicate dictionary with the below method

- (BOOL)isEqualToDictionary:(NSDictionary *)otherDictionary

Inside a for loop you can check the duplicates and if there anyone, you can remove it from an NSMutableArray using

- (void)removeObjectAtIndex:(NSUInteger)index

Answer 2

//You can filter you response like this:

//tempArray is data array which content webservice response

NSMutableArray *mainArray = [[NSMutableArray alloc]init];
for (int i = 0; i< [temprray count]; i ++) {
    if ([mainArray count]==0) {
        [mainArray addObject:[temprray objectAtIndex:0]];
    }
    else {

        NSDictionary *tempDict = [temprray objectAtIndex:i];
        BOOL isRecordFound = NO;
        for (int j = 0; j < [mainArray count]; j++) {
            NSDictionary *tempinnerDict = [mainArray objectAtIndex:j];
            if ([[tempinnerDict valueForKey:@"userid"] integerValue] == [[tempDict valueForKey:@"userid"] integerValue]) {
                isRecordFound = YES;
                break;
            }
        }
        if (!isRecordFound) {
            [mainArray addObject:tempDict];
        }
    }
}
