TableView详细解释

－、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:
                             SimpleTableIdentifier];
    if (cell == nil) {  
        cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault
                                       reuseIdentifier: SimpleTableIdentifier] autorelease];
 }
 cell.imageView.image=image;//未选cell时的图片
 cell.imageView.highlightedImage=highlightImage;//选中cell后的图片
 cell.text=//.....
 return cell;
}

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

//改变行的高度
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath{
    return 40;
}

//定位
[TopicsTable setContentOffset:CGPointMake(0, promiseNum * 44 + Chapter * 20)];

//返回当前所选cell
NSIndexPath *ip = [NSIndexPath indexPathForRow:row inSection:section];
[TopicsTable selectRowAtIndexPath:ip animated:YES scrollPosition:UITableViewScrollPositionNone];

[tableView setSeparatorStyle:UITableViewCellSelectionStyleNone];

//选中Cell响应事件
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{
 [tableView deselectRowAtIndexPath:indexPath animated:YES];//选中后的反显颜色即刻消失
}

//判断选中的行（阻止选中第一行）
-(NSIndexPath *)tableView:(UITableView *)tableView willSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    NSUInteger row = [indexPath row];
    if (row == 0)
        return nil;
   
    return indexPath;
}

//划动cell是否出现del按钮
- (BOOL)tableView:(UITableView *)tableView canEditRowAtIndexPath:(NSIndexPath *)indexPath {
}

//编辑状态
- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle
forRowAtIndexPath:(NSIndexPath *)indexPath
{
｝
[topicsTable setContentSize:CGSizeMake(0,controller.promiseNum * 44)];
//右侧添加一个索引表
- (NSArray *)sectionIndexTitlesForTableView:(UITableView *)tableView{
}
//返回Section标题内容
- (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section{
}
//自定义划动时del按钮内容
- (NSString *)tableView:(UITableView *)tableView
titleForDeleteConfirmationButtonForRowAtIndexPath:(NSIndexPath *)indexPath
//跳到指的row or section
[tableView scrollToRowAtIndexPath:[NSIndexPath indexPathForRow:0 inSection:0] atScrollPosition:UITableViewScrollPositionBottom animated:NO];
三、在UITableViewCell上建立UILable多行显示
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
    static NSString *CellIdentifier = @"Cell";   
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (cell == nil) {
        cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:CellIdentifier] autorelease];
  UILabel *Datalabel = [[UILabel alloc] initWithFrame:CGRectMake(10, 0, 320, 44)];
  [Datalabel setTag:100];
  Datalabel.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;
  [cell.contentView addSubview:Datalabel];
  [Datalabel release];
 } 
 UILabel *Datalabel = (UILabel *)[cell.contentView viewWithTag:100];
 [Datalabel setFont:[UIFont boldSystemFontOfSize:18]];
 Datalabel.text = [data.DataArray objectAtIndex:indexPath.row];
 cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
    return cell;
}
//选中cell时的颜色
typedef enum {
    UITableViewCellSelectionStyleNone,
    UITableViewCellSelectionStyleBlue,
    UITableViewCellSelectionStyleGray
} UITableViewCellSelectionStyle 
//cell右边按钮格式
typedef enum {
    UITableViewCellAccessoryNone,                   // don't show any accessory view
    UITableViewCellAccessoryDisclosureIndicator,    // regular chevron. doesn't track
    UITableViewCellAccessoryDetailDisclosureButton, // blue button w/ chevron. tracks
    UITableViewCellAccessoryCheckmark               // checkmark. doesn't track
} UITableViewCellAccessoryType
//是否加换行线
typedef enum {
    UITableViewCellSeparatorStyleNone,
    UITableViewCellSeparatorStyleSingleLine
} UITableViewCellSeparatorStyle//改变换行线颜色
tableView.separatorColor = [UIColor blueColor];
