ios学习--TableView详细解释

－、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];
