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)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];
