iPhone開發之UITableView詳解(2)

轉自：http://zyc-to.blog.163.com/blog/static/171524002010112831630425/


－、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說明






//Section總數
- (NSArray *)sectionIndexTitlesForTableView:(UITableView *)tableView{
return TitleData;
}




// Section Titles
//每個section顯示的標題
- (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section{
return @"";
}




//指定有多少個分區(Section)，默認爲1
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
return 4;
}




//指定每個分區中有多少行，默認爲1
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section{
}




//繪製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;//未選cell時的圖片
cell.imageView.highlightedImage=highlightImage;//選中cell後的圖片
cell.text=//.....
return cell;
}




//行縮進
-(NSInteger)tableView:(UITableView *)tableView indentationLevelForRowAtIndexPath:(NSIndexPath *)indexPath{
NSUInteger row = [indexPath row];
return row;
}




//改變行的高度
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath{
return 40;
}




//定位
[TopicsTable setContentOffset:CGPointMake(0, promiseNum * 44 + Chapter * 20)];




//返回當前所選cell
NSIndexPath *ip = [NSIndexPath indexPathForRow:row inSection:section];
[TopicsTable selectRowAtIndexPath:ip animated:YES scrollPosition:UITableViewScrollPositionNone];




[tableView setSeparatorStyle:UITableViewCellSelectionStyleNone];




//選中Cell響應事件
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{


[tableView deselectRowAtIndexPath:indexPath animated:YES];//選中後的反顯顏色即刻消失
}




//判斷選中的行（阻止選中第一行）
-(NSIndexPath *)tableView:(UITableView *)tableView willSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
NSUInteger row = [indexPath row];
if (row == 0)
return nil;


return indexPath;
}




//划動cell是否出現del按鈕
- (BOOL)tableView:(UITableView *)tableView canEditRowAtIndexPath:(NSIndexPath *)indexPath {
}




//編輯狀態
- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle
forRowAtIndexPath:(NSIndexPath *)indexPath
{
｝




[topicsTable setContentSize:CGSizeMake(0,controller.promiseNum * 44)];
//右側添加一個索引表
- (NSArray *)sectionIndexTitlesForTableView:(UITableView *)tableView{
}


//返回Section標題內容
- (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section{
}


//自定義划動時del按鈕內容
- (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多行顯示


- (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;
}








//選中cell時的顏色


typedef enum {
UITableViewCellSelectionStyleNone,
UITableViewCellSelectionStyleBlue,
UITableViewCellSelectionStyleGray
} UITableViewCellSelectionStyle




//cell右邊按鈕格式


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 
 


//是否加換行線


typedef enum {
UITableViewCellSeparatorStyleNone,
UITableViewCellSeparatorStyleSingleLine
} UITableViewCellSeparatorStyle




//改變換行線顏色


tableView.separatorColor = [UIColor blueColor];
