TableView詳細解釋

</pre> －、建立 UITableView<p></p><div style="padding:0px; margin:0px; color:rgb(44,44,44); font-family:宋體,'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];
