－、建立 UITableView
?DataTable = [[UITableView alloc] initWithFrame:CGRectMake(0, 0, 320, 420)];?[DataTable setDelegate:self];?[DataTable setDataSource:self];?[self.view addSubview:DataTable];?[DataTable release];?二、UITableView各Method说明?//Section总数- (NSArray *)sectionIndexTitlesForTableView:(UITableView *)tableView{?return TitleData;}?// Section Titles//每个section显示的标题- (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section{?return @"";}?//指定有多少个分区(Section)，默认为1- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {?return 4;}?//指定每个分区中有多少行，默认为1- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section{}?//绘制Cell-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {static NSString *SimpleTableIdentifier = @"SimpleTableIdentifier";???? ?UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:?? ? ? ? ? ? ? ? ? ? ? ? ? ?
