-、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cellNSIndexPath *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];
