转到link，它将描述UITableView所有的基础知识。的UITableView

主要方法是：

– tableView:cellForRowAtIndexPath: //所需的方法

– tableView:numberOfRowsInSection: //所需的方法

– numberOfSectionsInTableView: 

– sectionIndexTitlesForTableView: 

– tableView:sectionForSectionIndexTitle:atIndex: 

– tableView:titleForHeaderInSection: 

– tableView:titleForFooterInSection:

需要一个是那些你必须在代码中包含的。不要忘记将表代表和数据源与文件所有者链接起来。

而且，任何方法返回一个值，这是一个数据源方法和其他剩余的方法是委托方法

下面给出

委托方法

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath

数据源

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath 

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section 
- (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section 
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView

数据源方法：

-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section{}

和

-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{}

委托方法：

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{} 



- (void)tableView:(UITableView *)tableView didDeselectRowAtIndexPath:(NSIndexPath *)indexPath{}

这是我们用它来制作表格视图工作的主要方法。除此之外，还有很多方法。阅读UITableView委托和数据源文档以了解更多方法及其工作。
