iphone開發之TableView控制項執行個體

也許您對android中ListView控制項很熟悉，ListView為我們展示了一個列表形式的資料，在ios下的TableView為我們實現同樣的功能。TableView實現起來很簡單，下面看具體例子。建立一個項目，我們要在ViewController.h添加如下代碼：

<UITableViewDelegate, UITableViewDataSource>

顯而易見，這樣做的目的是為了為TableView添加資料，和實現UITableView委託方法。在ViewController.m中添加如下代碼：

#pragma mark - View lifecycle- (void)viewDidLoad       //{    [super viewDidLoad];    self.title = @"First Level";    NSArray *array = [[NSArray alloc] initWithObjects:@"Kobe", @"James", @"Wade", @"Rose", @"Yao", nil];  //Set tableViewCell's text     self.listData = array;    [array release];}- (void)viewDidUnload{    [super viewDidUnload];    // Release any retained subviews of the main view.    // e.g. self.myOutlet = nil;    self.listData = nil;}- (void) dealloc{    [self.listData release];    [super dealloc];}#pragma mark - Table view data source- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section{   // Return the number of rows in the section.    return [self.listData count];     //}- (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];    }        // Configure the cell...    NSUInteger row = [indexPath row];    cell.textLabel.text = [self.listData objectAtIndex:row];    cell.detailTextLabel.text = [self.listData objectAtIndex:row];

    UIImage *image = [UIImage imageNamed:@"wolfSpiderThumb.jpg"];    cell.imageView.image = image;    return cell;}/*// Override to support conditional editing of the table view.- (BOOL)tableView:(UITableView *)tableView canEditRowAtIndexPath:(NSIndexPath *)indexPath{    // Return NO if you do not want the specified item to be editable.    return YES;}*//*// Override to support editing the table view.- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath{    if (editingStyle == UITableViewCellEditingStyleDelete) {        // Delete the row from the data source        [tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationFade];    }       else if (editingStyle == UITableViewCellEditingStyleInsert) {        // Create a new instance of the appropriate class, insert it into the array, and add a new row to the table view    }   }*//*// Override to support rearranging the table view.- (void)tableView:(UITableView *)tableView moveRowAtIndexPath:(NSIndexPath *)fromIndexPath toIndexPath:(NSIndexPath *)toIndexPath{}*//*// Override to support conditional rearranging of the table view.- (BOOL)tableView:(UITableView *)tableView canMoveRowAtIndexPath:(NSIndexPath *)indexPath{    // Return NO if you do not want the item to be re-orderable.    return YES;}*/#pragma mark - Table view delegate- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{    // Navigation logic may go here. Create and push another view controller.         }

注釋很簡單，雖然是英文但我們看一下函數名就知道其作用了，這裡就不過多解釋了。
