本文介绍如何创建自定义的UITableViewCell类并使用XIB文件进行布局。通过注册和复用自定义单元格的方式，提高UITableView的数据展示效率。

新建一个类ContactCell，继承自UITableViewCell。新建一个xib文件（ContactCell.xib），视图为selfCell类。




在- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath方法中使用自定义的cell。

static NSString *CellIdentifier = @"Cell";

    UINib *nib = [UINib nibWithNibName:@"ContactCell" bundle:nil];

   BOOL registered = NO;

   if(!registered){

    [tableView registerNib:nib forCellReuseIdentifier:@"Cell"];

    ContactCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];

    registered = YES;

}


或者

    ContactCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];

    if (!cell) {

        cell = [[ContactCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:@"Cell"];

    }

    


iOS：使用Table View类(表视图）实现显示数据列表详解

1.将Table View控件（UITableView类的一个实例）添加到视图控制器中，Table View类实现显示数据列表时使用Table View Cell控件(UITableViewCell类的一个实例)来实现每一行。 2.Table View控件用于显示数据列表中的数据来源是所在的视图控制器。 Table View控件需要委托(delegate)和数据源(dataSource)（即将所在视图控制器作为其委托和数据源），Table View将一些工作分配给它的委托和数据源： 委托：用于配置表视图的外

这个方法是用来设置你的TableView中每一行显示的内容和格式的。 indexPath 用来指示当前单元格，它的row方法可以获得这个单元格的行号，section方法可以获得这个单元格所处的区域号 static NSString *CellIdentifier = @"cell";//可复用单元格标识 UITableViewCell *cell = [table...
