Objective C- numberOfRowsInSection method is not called properly in UITableView - objective-c

Question

In my table view, I have 7 section. Each section count is 3 initially.
When I launch my app, numberOfRowsInSection method is calling from last section count(6) but data are displayed in all sections properly.
When I reload my table after insert event numberOfRowsInSection is calling again from 6 not from 0 so how to resolve it?
-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
NSMutableArray *arrayOfItems = [workScheduleArray objectAtIndex:section];
return arrayOfItems.count;
}
-(void)insertNewDutyTimeRow:(UIButton *)addNewRowBtn atIndexPath:(NSIndexPath *)addNewDutyIndex
{
insertNewRow = [[NSMutableArray alloc]init];
[insertNewRow addObject:#"Start Time"];
[insertNewRow addObject:#"End time"];
[insertNewRow addObject:#"Service type"];
newArray = [workScheduleArray objectAtIndex:addNewDutyIndex.section];
[newArray insertObject:insertNewRow atIndex:addNewDutyIndex.row+1];
NSLog(#"WorkSchedule array:%#",workScheduleArray[addNewDutyIndex.section]);
[self.personalTable reloadData];
}

Answer 1

Your numberOfRowsInSection is generic, it returns the same number for all your sections. it begins by section 0 and ends by your last section (in your case its 6). So this is why you must specify all the cases. For example you can do this:
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
switch (section) {
case 0:
NSMutableArray *arrayOfItems = [workScheduleArray objectAtIndex:section];
return arrayOfItems.count;
{...}
}
}
