iPhone UITableView部分

Question

我一直在编写一个UITableView,每个单元格都会推出一个新的视图,我只想添加两个新的部分,一个是男性,一个是女性,第一个和第二个声音需要在男性部分,第三个声音需要在女性部分.

#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];
}

我想做的就是添加两个新的部分,一个是男性,一个是女性,第一个和第二个声音需要在男性部分,第三个声音需要在女性部分.请帮忙坚持一段时间!

Answer 1

tableView委托有一个名为numberOfSectionsInTableView的方法.返回要创建的部分数.

然后,在cellForRowAtIndexPath中使用indexPath其他属性[indexPath section]根据节来隔离行.

一个例子

- (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;
}
