－、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];
-
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
-
{
-
UITableViewCell *cell = [selftableView:tableView cellForRowAtIndexPath:indexPath];
-
return cell.frame.size.height;
-
}
-
-
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
-
{
-
NSArray* nibView = [[NSBundle mainBundle] loadNibNamed:@"ManagerTileCell" owner:nil options:nil];
-
UITableViewCell *cell = [nibView objectAtIndex:0];
-
cell.selectionStyle = UITableViewCellSelectionStyleNone;
-
///
-
-
UILabel *label = (UILabel*)[cell viewWithTag:0];
-
label.text = @"test";
-
return cell;
-
}
