I have a UITableView which I have assigned sections. When using didSelectRowAtIndex with indexPath.row I am not getting the correct value. Let's say I'm in section 2, then it starts the row index at 0 again and therefore I am getting the wrong index.
Can anyone tell me how to fix this? I realize that it is possible to get the section index by indexPath.section but I can't figure out how to use this.
bandDetailViewController.band = [self.programArray objectAtIndex:indexPath.row];
I hope you can help me. Thanks in advance :-)
EDIT:
Sample data. My cells for the table view is loaded from this plist.
<array>
<dict>
<key>name</key>
<string>Alphabeat</string>
<key>description</key>
<string>Long description.</string>
<key>scene</key>
<string>Store Scene</string>
<key>date</key>

I just came across this issue as well. I found a simple solution using the section number as you mentioned The following code uses segues to navigate to new controlView from two different sections with two different rows. VERY simple solution!
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
if (indexPath.section == 0)
{
switch(indexPath.row) {
case 0:
[self performSegueWithIdentifier:@"Mission" sender:self];
break;
case 1:
//[self performSegueWithIdentifier:@"Music" sender:self];
break;
}
}else{
switch(indexPath.row) {
case 0:
[self performSegueWithIdentifier:@"Contact" sender:self];
break;
case 1:
//[self performSegueWithIdentifier:@"Home" sender:self];
break;
}
}
}
The rows
are not consecutive and start from scratch in each section
:
section 0:
row 0
row 1
row 2
row ...
section 1:
row 0
row 1
row 2
row ...
...
The best way is to build an NSMutableArray sections with NSMutableArrays for the rows. Than you code gets very easy:
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
return cellSections.count;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
CellSection *cellSection = [cellSections objectAtIndex:section];
return cellSection.cellElements.count;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
NSString *cellIdentifier = [NSString stringWithFormat:@"Cell-%i-%i", indexPath.section, indexPath.row];
CellSection *cellSection = [cellSections objectAtIndex:indexPath.section];
CellElement *cellElement = [cellSection.cellElements objectAtIndex:indexPath.row];
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:cellIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:cellIdentifier] autorelease];
[cell.contentView addSubview:cellElement.contentView];
}
return cell;
}
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
CellSection *cellSection = [cellSections objectAtIndex:indexPath.section];
CellElement *cellElement = [cellSection.cellElements objectAtIndex:indexPath.row];
}
EDIT:
Just an example:
@interface CellSection : NSObject {
}
@property (nonatomic, retain) NSMutableArray *cellElements;
@property (nonatomic, retain) NSString *headerString;
@property (nonatomic, retain) UIView *headerView;
@end
@interface CellElement : NSObject {
}
@property (nonatomic, retain) UIView *contentView;
@property BOOL isSelectable;
@property BOOL hasAccessoryIndicator;
@property SEL action;
@end
