iphone练习之TableView

1、第一个要实现的效果如图：

新建一个基于Sigle view Application的项目，拖一个Table View到View上，实现Outlets：dataSource、delegate到File's Owner。

实现代码：

#import <UIKit/UIKit.h>//为了填充表格，必须使用一个协议,并且实现协议中的两个方法@interface ViewController : UIViewController<UITableViewDataSource>@end

#import "ViewController.h"@implementation ViewControllerNSMutableArray *listOfMovies;//设置table中的信息，行的单元格在索引路径-(UITableViewCell*)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{        static NSString *CellIdentifier=@"Cell";    //设置重复用的电池    UITableViewCell *cell=[tableView dequeueReusableCellWithIdentifier:CellIdentifier];    if(cell==nil){        cell=[[[UITableViewCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier]autorelease];            }    //设置一行cell显示的值    NSString *cellValue=[listOfMovies objectAtIndex:indexPath.row];    cell.textLabel.text=cellValue;    //添加图片    UIImage *image=[UIImage imageNamed:@"ic_ic.jpg"];    cell.imageView.image=image;    return cell;}//节的行数-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section{    return [listOfMovies count];}-(NSString*)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section{    //显示页眉    return @"Movie List";}-(NSString*)tableView:(UITableView *)tableView titleForFooterInSection:(NSInteger)section{    //显示页脚    return @"by Denzel Washington";}//选择在指数径行-(void)tableView:(UITableView*)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{    //得到选中该行的内容    NSString *movieSelected=[listOfMovies objectAtIndex:indexPath.row];    //封装成msg    NSString *msg=[NSString stringWithFormat:@"You have selected %@",movieSelected];    //用警告框弹出    UIAlertView *alert=[[UIAlertView alloc]initWithTitle:@"Movie selected" message:msg delegate:self cancelButtonTitle:@"ok" otherButtonTitles: nil];    //显示弹出对话框    [alert show];    //释放alert    [alert release];}//缩进水平排在索引路径-(NSInteger)tableView:(UITableView *)tableView indentationLevelForRowAtIndexPath:(NSIndexPath *)indexPath{    return [indexPath row]%2;}//在索引路径为行高度-(CGFloat)tableView:(UITableView*)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath{    return 70;}- (void)viewDidLoad{    listOfMovies=[[NSMutableArray alloc]init];    [listOfMovies addObject:@"Training Day"];    [listOfMovies addObject:@"Remember the Titans"];    [listOfMovies addObject:@"John Q."];     [listOfMovies addObject:@"The Bone Collector"];    [listOfMovies addObject:@"Ricochet"];     [listOfMovies addObject:@"The Siege"];     [listOfMovies addObject:@"Malcolm X"];    [listOfMovies addObject:@"Antwone Fisher"];     [listOfMovies addObject:@"Courage Under Fire"];    [listOfMovies addObject:@"He Got Game"];     [listOfMovies addObject:@"The Pelican Brief"];     [listOfMovies addObject:@"Glory"];    [listOfMovies addObject:@"The Preacher’s Wife"];    [super viewDidLoad];// Do any additional setup after loading the view, typically from a nib.}-(void)dealloc{    [listOfMovies release];    [super dealloc];}

我只给出相应的方法实现！

2、第二种实现效果

新建一个基于Master-Detail Application；在文件里新建一个Property List类型的文件名为Movies.plist,内容如下：

实现代码：

#import <UIKit/UIKit.h>@class DetailViewController;@interface MasterViewController : UITableViewController{    NSDictionary *movieTitles;    NSArray *years;}@property (nonatomic,retain)NSDictionary *movieTitles;@property (nonatomic,retain)NSArray *years;@property (strong, nonatomic) DetailViewController *detailViewController;@end

#import "MasterViewController.h"#import "DetailViewController.h"@implementation MasterViewController@synthesize movieTitles,years;- (void)dealloc{    [_detailViewController release];    [movieTitles release];    [years release];    [super dealloc];}- (void)viewDidLoad{    //文件名字及类型    NSString *path=[[NSBundle mainBundle]pathForResource:@"Movies" ofType:@"plist"];    //获取内容为字典类型    NSDictionary *dic=[[NSDictionary alloc]initWithContentsOfFile:path];    //把所有内容赋给movieTitles    self.movieTitles=dic;    [dic release];    /*获取所有的年份，并且升序键     2000,    2001,    2002,    2004,    2006,    2007,    2008*/        NSArray *array=[[self.movieTitles allKeys]sortedArrayUsingSelector:@selector(compare:)];    //赋给数组年    self.years=array;        [super viewDidLoad];// Do any additional setup after loading the view, typically from a nib.}-(NSInteger)numberOfSectionsInTableView:(UITableView *)tableView{    //返回多少总行    return [self.years count];}//每节的行数-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section{    //获取每一年    NSString *year=[self.years objectAtIndex:section];    //获取每个年里的值，得到一个数组    NSArray *movieSection=[self.movieTitles objectForKey:year];    //返回这个键总共有多少值    return [movieSection count];}//添写每一节的内容-(UITableViewCell*)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{        static NSString *CellIdentifier = @"Cell";        UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];                if(cell==nil){        cell=[[[UITableViewCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier]autorelease];    }    //获取每一年    NSString *year=[self.years objectAtIndex:[indexPath section]];   //获取每年里的值    NSArray *movieSection=[self.movieTitles objectForKey:year];   //设置每一节里的内容    cell.textLabel.text=[movieSection objectAtIndex:[indexPath row]];    return cell;}//年的页眉-(NSString*)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section{    NSString *year=[self.years objectAtIndex:section];    return year;}- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{    if (!self.detailViewController) {        self.detailViewController = [[[DetailViewController alloc] initWithNibName:@"DetailViewController" bundle:nil] autorelease];    }    [self.navigationController pushViewController:self.detailViewController animated:YES];}

打开MasterViewController.xib文件把Table View的属性Style改成Grouped,并在MasterViewController.m添加一个索引方法如下代码：

//有时候列表过长，添加此方法实现索引，按每一年索引-(NSArray*)sectionIndexTitlesForTableView:(UITableView *)tableView{    return years;}

实现的效果如下图：

下面是切换到另一个节目，并把电影的名字带回去：

首先在DetailViewController.m文件中添加如入代码：

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{    NSString *year = [self.years objectAtIndex:[indexPath section]];    NSArray *movieSection = [self.movieTitles objectForKey:year];    NSString *movieTitle = [movieSection objectAtIndex:[indexPath row]];    NSString *message = [[NSString alloc]initWithFormat:@"%@", movieTitle];        if (!self.detailViewController) {        self.detailViewController = [[[DetailViewController alloc] initWithNibName:@"DetailViewController" bundle:nil] autorelease];    }    self.detailViewController.movieSelected=message;    [self.navigationController pushViewController:self.detailViewController animated:YES];}

在DetailViewController.xib文件中添加一个label;

在DetailViewController.h文件中添加如下信息：

#import <UIKit/UIKit.h>@interface DetailViewController : UIViewController{    NSString *movieSelected;//电影的名字    IBOutlet UILabel *label;}@property (strong, nonatomic) id detailItem;@property (strong, nonatomic) IBOutlet UILabel *detailDescriptionLabel;@property (nonatomic,retain)NSString *movieSelected;@property (nonatomic,retain)IBOutlet UILabel *label;@end

在DetailViewController.m文件中添加：

@interface DetailViewController ()- (void)configureView;@end@implementation DetailViewController@synthesize detailItem = _detailItem;@synthesize detailDescriptionLabel = _detailDescriptionLabel;@synthesize movieSelected,label;- (void)dealloc{    [_detailItem release];    [_detailDescriptionLabel release];    [movieSelected release];    [super dealloc];}- (void)viewDidLoad{    self.navigationItem.title = movieSelected;    label.text=movieSelected;    [super viewDidLoad];// Do any additional setup after loading the view, typically from a nib.    [self configureView];}

实现效果图：
