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

//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];
}
}
}

Answer 2

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
