TableView详细解释

</pre> －、建立 UITableView<p></p><div style="padding:0px; margin:0px; color:rgb(44,44,44); font-family:宋体,'Arial Narrow',arial,serif; font-size:14px"></div><pre name="code" class="html"> 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)editingStyleforRowAtIndexPath:(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 *)tableViewtitleForDeleteConfirmationButtonForRowAtIndexPath:(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];
