创建一个简单表-UITableView

 1.创建基于View-based Application的工程，添加一个UITableView控键.

 2. .h文件中加入委托协议 UITableViewDelegate,UITableViewDataSource  并链接

 3. .m文件中方法实现：代码如下：

 

重写VIewDidLoad方法

 

- (void)viewDidLoad
{
    [super viewDidLoad];
    NSArray *array = [[NSArray alloc] initWithObjects:@"The First One",@"The Second One",@"The Third One",@"The Four one", nil];
    self.listData = array;
    [array release];
}

 @end 之前加入如下代码：

 

#pragma mark -
#pragma mark Table View Data Source Methods

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section //返回目标行数
{
    return [self.listData count];
}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath   //返回每行的内容
{
    static NSString *thekey = @"thekey";   //定义键值标示符
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:thekey];
    if(cell == Nil){
        cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:thekey] autorelease];
    }
    
    NSUInteger row = [indexPath row];
  UIImage image = [UIImage imageNamed:@"apple.png"];
    cell.image = image;   //添加cell前的图像
    cell.textLabel.text = [listData objectAtIndex:row];
    return cell;
    
}
#pragma mark Table Delegate Methods

- (NSInteger)tableView:(UITableView *)tableView indentationLevelForRowAtIndexPath:(NSIndexPath *)indexPath  //缩进方法
{
    NSUInteger row = [indexPath row];
    return row;
}

- (NSIndexPath *)tableView:(UITableView *)tableView willSelectRowAtIndexPath:(NSIndexPath *)indexPath //行选择
{
    NSUInteger row = [indexPath row];
    if(row == 0){
        return nil;
    }
    return indexPath;

}
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
 //选择后执行的事件
{
    NSUInteger row = [indexPath row];
    NSString *Value = [listData objectAtIndex:row];
    NSString *showMessage = [[NSString alloc] initWithFormat:@"%@" ,Value];
    UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"You Select" message:showMessage delegate:self cancelButtonTitle:@"Yes" otherButtonTitles: nil];
    [alert show];
    [alert release];
    [showMessage release];

     }

- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath     //改变行高
{
    return 150;
}
