Pull to refresh resulting app to crash: NSRangeException, reason: index 8 beyond bounds [0 .. 4]

Sorry if this has been asked before but I can't find the answer to my problem.

I wrote code for pull to refresh but it crashed IF the result array count is different from the

indexPath.row

my code goes for this:

-(void)loadMore:(id) sender {
    loadFlag = 1; 
    NSString *employeeID = @"aaa"; 
    days = 3;
    int projIDNum = 1234; 
    int depCode = 1234000001;     
    int caseNum = 45678; 
    NSString *result = [client report_search:employeeID case_no:caseNum status:loadFlag day:days project_id:projIDNum 
        dep_code:depCode count:10];

    if ([result isEqualTo:@"[]"]) {
        [Utilities callAlert:self title:@"No More Data" body:@"There is no other data contains"];
        [refresh endRefreshing]; 
    } else { 
        NSData *jsonData = [result dataUsingEncoding: NSUTF8StringEncoding]; 
        NSError *error; [resultArr removeAllObjects]; 
        // resultArr is a NSMutableArray and it is the data source of the table
        resultArr = [[NSJSONSerialization JSONObjectWithData:jsonData options: 0 error:&error] mutableCopy]; 
        [refresh endRefreshing]; 
        [_mSearchTableView reloadData]; 
    } 
}

If I get full 10 data result, the program itself won't crash but it happens when I get less than 10 datas from web service. I kept getting this exception,

NSRangeException, reason: index 8 beyond bounds [0 .. 4]

My tableview setting:

-(NSInteger) numberOfSectionsInTableView:(UITableView *)tableView { 
    return 1; 
}

-(NSInteger) table:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
     return [resultArr count];
 }

-(UITableViewCell) tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
    NSString *cellIdentifier = @"cell"; 
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:cellIdentifier forIndexPath:indexPath]; 

    // to clear the cell
    for ([UIView *view in [cell.contentView subviews]]) { 
        if ([view isKindOfClass:[UIView class]]) { 
            [view removeFromSuperview]; 
        } 
    } 

    UILabel *titleLabel = [[UILabel alloc] init];
    if (cell == nil) { 
        cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:cellIdentifier]; 
    } else {
        titleLabel = [cell.contentView viewWithTag:100]; 
    } 

    CGRect location = CGRectMake(20, 20, 71/75, 40/146); 
    titleLabel = [[UILabel alloc] initWithFrame:location]; 
    titleLabel.textAlignment = NSTextAlignmentNatural; 
    titleLabel.text = [resultArr valueForKey:@"title"][indexPath.row]; // this is where the app crashed
    [cell.contentView addSubview:titleLabel];

    return cell; 
}

also giving out the resultArr's format and the content at the time it crashed

print out result: [

    Content = "Test\nTest\n";
    "Create_Datetime" = "2016-09-12 10:18:25"; 
    "Project_ID" = 2023; 
    Status = 4; "CASE_NO" = 17704; 
    Title = "Table title"; 
    "Update_Datetime" = "2016-09-12 10:19:09"; 
    },
    {
    Content = "Fhujhfdfhjoookbvv\nGu..."; 
    "Create_Datetime" = "2016-09-12 10:09:28"; 
    "Project_ID" = 2023;
