iphone練習之TableView

1、第一個要實現的效果

建立一個基於Sigle view Application的項目，拖一個Table View到View上，實現Outlets：dataSource、delegate到File's Owner。

實現代碼：

#import <UIKit/UIKit.h>//為了填充表格，必須使用一個協議,並且實現協議中的兩個方法@interface ViewController : UIViewController<UITableViewDataSource>@end

#import "ViewController.h"@implementation ViewControllerNSMutableArray *listOfMovies;//設定table中的資訊，行的儲存格在索引路徑-(UITableViewCell*)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{        static NSString *CellIdentifier=@"Cell";    //設定重複用的電池    UITableViewCell *cell=[tableView dequeueReusableCellWithIdentifier:CellIdentifier];    if(cell==nil){        cell=[[[UITableViewCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier]autorelease];            }    //設定一行cell顯示的值    NSString *cellValue=[listOfMovies objectAtIndex:indexPath.row];    cell.textLabel.text=cellValue;    //添加圖片    UIImage *image=[UIImage imageNamed:@"ic_ic.jpg"];    cell.imageView.image=image;    return cell;}//節的行數-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section{    return [listOfMovies count];}-(NSString*)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section{    //顯示頁首    return @"Movie List";}-(NSString*)tableView:(UITableView *)tableView titleForFooterInSection:(NSInteger)section{    //顯示頁尾    return @"by Denzel Washington";}//選擇在指數徑行-(void)tableView:(UITableView*)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{    //得到選中該行的內容    NSString *movieSelected=[listOfMovies objectAtIndex:indexPath.row];    //封裝成msg    NSString *msg=[NSString stringWithFormat:@"You have selected %@",movieSelected];    //用警告框彈出    UIAlertView *alert=[[UIAlertView alloc]initWithTitle:@"Movie selected" message:msg delegate:self cancelButtonTitle:@"ok" otherButtonTitles: nil];    //顯示彈出對話方塊    [alert show];    //釋放alert    [alert release];}//縮排水平排在索引路徑-(NSInteger)tableView:(UITableView *)tableView indentationLevelForRowAtIndexPath:(NSIndexPath *)indexPath{    return [indexPath row]%2;}//在索引路徑為行高度-(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];}

我只給出相應的方法實現！

2、第二種實現效果

建立一個基於Master-Detail Application；在檔案裡建立一個Property List類型的檔案名稱為Movies.plist,內容如下：

實現代碼：

#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{    //檔案名稱字及類型    NSString *path=[[NSBundle mainBundle]pathForResource:@"Movies" ofType:@"plist"];    //擷取內容為字典類型    NSDictionary *dic=[[NSDictionary alloc]initWithContentsOfFile:path];    //把所有內容賦給movieTitles    self.movieTitles=dic;    [dic release];    /*擷取所有的年份，並且升序鍵     2000,    2001,    2002,    2004,    2006,    2007,    2008*/        NSArray *array=[[self.movieTitles allKeys]sortedArrayUsingSelector:@selector(compare:)];    //賦給數組年    self.years=array;        [super viewDidLoad];// Do any additional setup after loading the view, typically from a nib.}-(NSInteger)numberOfSectionsInTableView:(UITableView *)tableView{    //返回多少總行    return [self.years count];}//每節的行數-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section{    //擷取每一年    NSString *year=[self.years objectAtIndex:section];    //擷取每個年裡的值，得到一個數組    NSArray *movieSection=[self.movieTitles objectForKey:year];    //返回這個鍵總共有多少值    return [movieSection count];}//添寫每一節的內容-(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];    }    //擷取每一年    NSString *year=[self.years objectAtIndex:[indexPath section]];   //擷取每年裡的值    NSArray *movieSection=[self.movieTitles objectForKey:year];   //設定每一節裡的內容    cell.textLabel.text=[movieSection objectAtIndex:[indexPath row]];    return cell;}//年的頁首-(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];}

開啟MasterViewController.xib檔案把Table View的屬性Style改成Grouped,並在MasterViewController.m添加一個索引方法如下代碼：

//有時候列表過長，添加此方法實現索引，按每一年索引-(NSArray*)sectionIndexTitlesForTableView:(UITableView *)tableView{    return years;}

實現的效果如：

下面是切換到另一個節目，並把電影的名字帶回去：

首先在DetailViewController.m檔案中添加如入代碼：

- (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檔案中添加一個label;

在DetailViewController.h檔案中添加如下資訊：

#import <UIKit/UIKit.h>@interface DetailViewController : UIViewController{    NSString *movieSelected;//電影的名字    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檔案中添加：

@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];}
