How to add cells to custom sections in UITableView - ios

Question

I have three sections in my UITableView and when I create objects to go into this UITableView, I want to specify which section I want it to go into. I do this by adding it to one of three arrays. Note all objects are initially added to a holder NSMutableArray called objects.
for (Profile *p in self.objects) {
if ([p.type isEqualToString:#"eol"]) {
[self.eolobjects addObject:p];
}
else if ([p.type isEqualToString:#"ae"]) {
[self.aeobjects addObject:p];
}
else if ([p.type isEqualToString:#"mw"]) {
[self.mwobjects addObject:p];
}
The problem arises when I want to segue to a detailViewController
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {
if ([[segue identifier] isEqualToString:#"showDetail"]) {
NSIndexPath *indexPath = [self.tableView indexPathForSelectedRow];
Profile *object = self.objects[indexPath.row];
[[segue destinationViewController] setDetailItem:object];
}
}
Because of the line:
Profile *object = self.objects[indexPath.row];
If I click (for example)the first object in any section, I will always create an object of the item at the first index of the objects array, not the object in the first index of the array which populates the section I am clicking in. The same is true if I change self.objects to any of my three other arrays.
Is there an easier way to add cells to sections in a UITableView or is there a way to fix my problem? Thanks
My data source methods look like this:
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
// Return the number of sections.
return 3;
}
- (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section
{
if (section ==0) {
return #"Evolution of Life";
}
else if (section==1){
return #"Active Earth";
}
else if (section==2){
return #"Mineral Wealth";
}
return #"";
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
// Return the number of rows in the section.
switch (section) {
case 0: return self.eolobjects.count; break;
case 1: return self.aeobjects.count; break;
case 2: return self.mwobjects.count; break;
}
return 0;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:#"Cell" forIndexPath:indexPath];
if (indexPath.section == 0) {
Profile *profile = self.eolobjects[indexPath.row];
cell.textLabel.text = [profile name];
return cell;
}
else if (indexPath.section ==1){
Profile *profile = self.aeobjects[indexPath.row];
cell.textLabel.text = [profile name];
return cell;
}
else if (indexPath.section ==2){
Profile *profile = self.mwobjects[indexPath.row];
cell.textLabel.text = [profile name];
return cell;
}
return cell;
}

Answer 1

You have two solutions
Try this
Profile *object =nil;
switch (indexPath.) {
case 0: object = self.eolobjects[indexPath.row]; break;
case 1: object = self.aeobjects[indexPath.row]; break;
case 2: object = self.mwobjects[indexPath.row]; break;
}
Or you can put all the 3 arrays in one array and access them easily like this allObjects[indexPath.section][indexPath.row]
