UITableView取消選中顏色、常用操作

使用空白view取代cell

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{

　　//取消選中顏色

　　UIView *backView = [[UIView alloc] initWithFrame:cell.frame];
　　cell.selectedBackgroundView = backView;
　　cell.selectedBackgroundView.backgroundColor = [UIColor clearColor];

　　//取消邊框線

　　[cell setBackgroundView:[[UIView alloc] init]];          //取消邊框線
      cell.backgroundColor = [UIColor clearColor];

｝

 

//在navigation中tableviewCell選中后返回無選中項

//單擊一個cell
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    UITableViewCell *cell = (UITableViewCell *)[tableView cellForRowAtIndexPath:indexPath];
    if(cell.tag == 0){

　　　//注銷cell單擊事件
        cell.selected = NO;
    }else {
        [tableView deselectRowAtIndexPath:[tableView indexPathForSelectedRow] animated:YES];　　//取消選中項
        BabyScheduler *babyScheduler=[listData objectAtIndex:indexPath.row-1];
        [delegate showVaccinationView:babyScheduler];    
    }
}

- (void)viewDidLoad
{
    self.title = NSLocalizedString(@"TempGroupViewTitle", @"");
    self.view.backgroundColor=[UIUtils defaultViewBackground];
    self.tempGroupTableView.backgroundColor=[UIColor clearColor];
    self.tempGroupTableView.separatorColor=[UIColor clearColor];    //分割cell線顏色
    self.tempGroupTableView.separatorStyle=UITableViewCellSeparatorStyleNone;   //不帶分割線樣式
    self.tempGroupTableView.rowHeight=45.0;
    
    self.navigationItem.rightBarButtonItem = self.editButtonItem;   //添加navigation按鈕
    self.groupList = [DBManager selectTempGroup];   //獲取分組信息
//    NSLog(@"-----%d",[groupList count]);
    [super viewDidLoad];
}

if (!cell)----當cell為空？真：假

//設置cell的高度

#pragma mark - Table view delegate
-(CGFloat)tableView:(UITableView*)tableView heightForHeaderInSection:(NSInteger)section
{
    if(section==1)return 45;
    return 0;
}

//返回自定義hrader
-(UIView*) tableView:(UITableView*)tableView viewForHeaderInSection:(NSInteger)section
{
    if (section==1) { //第二區
        UIView *view=[[UIView alloc] initWithFrame:CGRectMake(0, 0, 305, 38)];
        UIImageView* backgroundView=[[UIImageView alloc] initWithImage:[UIImage imageNamed:@"title.png"]];
        backgroundView.frame=CGRectMake(0, 0, 123, 38);
        [view addSubview:backgroundView];
        [backgroundView release];
        view.backgroundColor=[UIColor clearColor];
        UILabel *label=[[UILabel alloc] initWithFrame:CGRectMake(30, 0, 93, 38)];
        label.backgroundColor=[UIColor clearColor];       
        label.textColor=[UIColor whiteColor];
        label.text=NSLocalizedString(@"Section_Title_My_Group_Name", @"");
        [view addSubview:label];
        [label autorelease];
        return  [view autorelease];
    }
    return nil;
}

//向tableview填充數據
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    //當第一個分區得最后一行
    if ((indexPath.section==0)&&(indexPath.row==[groupList count])) {
        static NSString *AddGroupViewCellIdentifier = @"AddGroupViewCell";
        
        UITableViewCell *cell=[[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:AddGroupViewCellIdentifier] autorelease];
        // key 說明性文字
        cell.textLabel.text=NSLocalizedString(@"Add_New_Group", @"add new group");
        cell.textLabel.backgroundColor=[UIColor clearColor];
        cell.textLabel.textAlignment=UITextAlignmentCenter;     //cell中text文本居中
        cell.backgroundColor=[UIUtils defaultContactCellBackgroundColor];
        cell.tag=-1;
        return  cell;
    }
    static NSString *SimpleTableIdentifier = @"GroupListViewCell";
    //使用自定義cell
    //查找SimpleTableIdentifier的cell，為空初始化
    GroupListViewCell *cell = (GroupListViewCell *)[tableView dequeueReusableCellWithIdentifier:SimpleTableIdentifier];
    if (!cell)
    {
        [[NSBundle mainBundle] loadNibNamed:SimpleTableIdentifier owner:self options:nil];
        cell = groupCell;
        cell.backgroundColor=[UIUtils defaultContactCellBackgroundColor];
        self.groupCell = nil;        
    }
    cell.group=[groupList objectAtIndex:indexPath.row];

//設置cell右邊箭頭，v等等，有枚舉變量可供選擇
//    cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
    NSUInteger row = [indexPath row];
    cell.tag = row;
    [SimpleTableIdentifier release];
    return cell;
    
}

 

cell可刪除

// 指定tableview可刪除的區域
- (BOOL)tableView:(UITableView *)tableView canEditRowAtIndexPath:(NSIndexPath *)indexPath
{
    return indexPath.section==1?YES:NO;
}
//可刪除的cell
-(UITableViewCellEditingStyle)tableView:(UITableView *)tableView
          editingStyleForRowAtIndexPath:(NSIndexPath *)indexPath{
    NSUInteger row = [indexPath row];
    if (row == [groups count]) {
        return UITableViewCellEditingStyleNone;
    }else {
        return UITableViewCellEditingStyleDelete;
    }
}

// 刪除之后
- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath
{
    if (editingStyle == UITableViewCellEditingStyleDelete) {
        // Delete the row from the data source
        [self deleteGroup:indexPath.row];
        [tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationFade];
    }   
    else if (editingStyle == UITableViewCellEditingStyleInsert) {
        // Create a new instance of the appropriate class, insert it into the array, and add a new row to the table view
    }   
}

 

//當前選中行設為非選中

[self.membersListView deselectRowAtIndexPath:membersListView.indexPathForSelectedRow animated:YES];
