一、建立 UITableView
DataTable = [[UITableView alloc] initWithFrame:CGRectMake(0, 0, 320, 420)]; [DataTable setDelegate:self]; [DataTable setDataSource:self]; [self.view addSubview:DataTable];
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];
三、设置cell边框线长度
tableView.separatorInset=UIEdgeInsetsZero;
四、设置cell边框线颜色
tableView.separatorColor = Colour(224, 231, 227, 1);
五、设置没有内容的cell没有分割线
原理：从新对footView进行重置
table.tableFooterView = [[UIView alloc] init];
六、设置UITableView是否显示滚动条
[table setShowsHorizontalScrollIndeiator:YES]; //设置水平滚动条可见[table setShowsVerticalScrollIndicator:YES]; //设置垂直滚动条可见
七、当点击cell时显示灰色，取消点击后显示正常颜色
[tableView deselectRowAtIndexPath:indexPath animated:YES];
八、删除某一行
//设置删除时编辑状态
-(void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath{ if (editingStyle==UITableViewCellEditingStyleDelete) { //如果是删除就从数组中移除元素 [list removeObjectAtIndex:indexPath.row]; [contentTableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationFade]; }}
修改名字
//-(NSString *)tableView:(UITableView *)tableView titleForDeleteConfirmationButtonForRowAtIndexPath:(NSIndexPath *)indexPath//{// return @"下载"; //}
九、添加一行
1、———----- [hist getHistoryModel:^(HistoryCaseModel *model) { [self.historyCaseArray addObject:model]; [contentTableView beginUpdates]; [contentTableView insertRowsAtIndexPaths:[NSArray arrayWithObject:[NSIndexPath indexPathForRow:self.historyCaseArray.count-1 inSection:2]] withRowAnimation:UITableViewRowAnimationFade]; [contentTableView endUpdates];// }]; 2、----------- (void)viewDidLoad{ [super viewDidLoad]; contentTableView = [[UITableView alloc] initWithFrame:CGRectMake(0, 0, 320, 480) style:UITableViewStylePlain]; [contentTableView setEditing:YES animated:YES]; contentTableView.delegate = self; contentTableView.dataSource =self; [self.view addSubview:contentTableView]; array = [[NSMutableArray alloc] initWithObjects:@"1",@"2",@"3",@"4", nil];}#pragma mark - UITableViewDelegate**UITableViewDataSource-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section{ return array.count;}-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{ static NSString *cellIdentifier = @"Cell"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:cellIdentifier]; if (cell==nil) { cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:cellIdentifier]; } cell.textLabel.text = array[indexPath.row]; return cell;}-(void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath{ NSUInteger row = [indexPath row]; if(editingStyle==UITableViewCellEditingStyleInsert) { NSArray *insertIndexPaths = [NSArray arrayWithObjects:indexPath, nil]; [array insertObject:@"insert new cell" atIndex:row]; [tableView insertRowsAtIndexPaths:insertIndexPaths withRowAnimation:UITableViewRowAnimationMiddle]; }}-(UITableViewCellEditingStyle)tableView:(UITableView *)tableView editingStyleForRowAtIndexPath:(NSIndexPath *)indexPath{ return UITableViewCellEditingStyleInsert;}
//设置分割线长度
[self.contentTableView setSeparatorInset:UIEdgeInsetsMake(0, 0, 0, 0)];
//加载xib文件cell
cell=[[[NSBundle mainBundle]loadNibNamed:@"ActivitieTableViewCell" owner:self options:nil]lastObject];
