-、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
//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lyttzx.com
tableView.separatorColor
= [UIColor blueColor];
