一、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];
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];
