iPhone UITableView Sections - iphone

Question

I have been programming a UITableView and each cells pushes a new view, All I Want to do is add two new sections one male and one female, first and second voice need to be in the male section and the third voice needs to be in the female section.
#import "FirstLevelViewController.h"
#import "SecondLevelViewController.h"
#import "DisclosureDetailController.h"
#import "SecondVoiceController.h"
#import "ThirdVoiceController.h"
#implementation FirstLevelViewController
#synthesize controllers;
-(void)viewDidLoad {
self.title = #"Voices";
NSMutableArray *male = [[NSMutableArray alloc] init];
DisclosureDetailController *th = [DisclosureDetailController alloc];
th.title = #"First Voice";
[male addObject:th];
[th release];
SecondVoiceController *array2 = [SecondVoiceController alloc];
array2.title = #"Second Voice";
[male addObject:array2];
[array2 release];
ThirdVoiceController *array3 = [ThirdVoiceController alloc];
array3.title = #"Third Voice";
[male addObject:array3];
[array3 release];
self.controllers = male;
[male release];
[super viewDidLoad];
}
-(void)viewDidUnload {
self.controllers = nil;
[super viewDidUnload];
}
-(void)dealloc {
[controllers release];
[super dealloc];
}
-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
return [self.controllers count];
}
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *FirstLevelCell= #"FirstLevelCell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:FirstLevelCell];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:FirstLevelCell] autorelease];
}
NSUInteger row = [indexPath row];
SecondLevelViewController *controller = [controllers objectAtIndex:row];
cell.textLabel.text = controller.title;
cell.imageView.image = controller.rowImage;
cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
return cell;
}
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
NSUInteger row = [indexPath row];
SecondLevelViewController *nextViewController = [self.controllers
objectAtIndex:row];
[self.navigationController pushViewController:nextViewController animated:YES];
}
All I Want to do is add two new sections one male and one female, first and second voice need to be in the male section and the third voice needs to be in the female section. Please help been stuck on this for a while!

Answer 1

The tableView delegate has a method called numberOfSectionsInTableView. Return the number of sections that you want to create.
Then, in the cellForRowAtIndexPath use indexPath's other property [indexPath section] to segregate rows based on sections.
An example
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
return 2; //one male and other female
}
-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
switch(section){
case 0:
return [male count];
break;
case 1:
return [female count];
break;
}
}
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *FirstLevelCell= #"FirstLevelCell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:FirstLevelCell];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:FirstLevelCell] autorelease];
}
SecondLevelViewController *controller;
switch([indexPath section]){
case 0:
controller = [male objectAtIndex: [indexPath row] ];
break;
case 1:
controller = [female objectAtIndex: [indexPath row] ];
break;
}
cell.textLabel.text = controller.title;
cell.imageView.image = controller.rowImage;
cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
return cell;
}

Hows this?
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
// Return the number of sections.
return 2;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
// Return the number of rows in the section.
switch (section) {
case 0:
return # of rows in section;
break;
case 1:
return # of rows in section;
break;
}
return 0;
}
