iPhone开发之UITableView简单应用（5）

  1.单击菜单File->New->Proget.....新建一个项目：

   

   2.选择Single View Application模板，单击Next：

   

   3.将项目命名为Simple Table，单击Next->Create，新建项目：

   

   4.单击ViewController.xib文件,在View视图上添加控件Table View：

  

  5.为控件Table View添加数据、方法委托：

  

 

  6.单击ViewController.h头文件，为ViewController添加数据成员：

#import <UIKit/UIKit.h>

@interface ViewController : UIViewController<UITableViewDelegate,UITableViewDataSource>
{
   NSArray *list;
}
@property(nonatomic,retain)NSArray *list;

@end

  7.单击ViewController.m文件，为ViewController添加数据和协议方法：

#import "ViewController.h"

@interface ViewController ()

@end

@implementation ViewController
@synthesize list;

- (void)viewDidLoad
{
    [super viewDidLoad];
	// Do any additional setup after loading the view, typically from a nib.
    NSArray *array = [[NSArray alloc]initWithObjects:@"广东",@"湖南",@"北京",@"上海",@"香港",@"澳门", nil];
    self.list = array;
    [array release];
}

- (void)viewDidUnload
{
    [super viewDidUnload];
    // Release any retained subviews of the main view.
    self.list = nil;
}

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
    return (interfaceOrientation != UIInterfaceOrientationPortraitUpsideDown);
}

-(void)dealloc
{
    [super dealloc];
    [list release];
}

#pragma mark -
#pragma mark Table Data Source Methods

-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
    return [list count];
}

-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *identfier=@"placetable";
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:identfier];
    if(cell==nil)
    {
        cell = [[UITableViewCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:identfier];
    }
    NSInteger row = [indexPath row];
    cell.textLabel.text = [list objectAtIndex:row];
    return cell;
}

-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    NSInteger row = [indexPath row];
    NSString *message = [list objectAtIndex:row];
    UIAlertView *alert = [[UIAlertView alloc]initWithTitle:@"你选择:" message:message delegate:self cancelButtonTitle:@"确定" otherButtonTitles:nil];
    [alert show];
    [alert release];
}

@end

  8.现在可以单击运行按钮，测试程序，单击其中的选项“广东”，效果如下：
