UITableView取消选中颜色、常用操作

UITableView取消选中颜色、常用操作

 

使用空白view取代cell

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

　　//取消选中颜色

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

　　//取消边框线

　　[cell setBackgroundView:[[UIView alloc] init]];          //取消边框线
      cell.backgroundColor = [UIColor clearColor];

｝

//在navigation中tableviewCell选中后返回无选中项

//单击一个cell
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    UITableViewCell *cell = (UITableViewCell *)[tableView cellForRowAtIndexPath:indexPath]; 
    if(cell.tag == 0){

　　　//注销cell单击事件
        cell.selected = NO;
    }else {
        [tableView deselectRowAtIndexPath:[tableView indexPathForSelectedRow] animated:YES];　　//取消选中项
        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线颜色
    self.tempGroupTableView.separatorStyle=UITableViewCellSeparatorStyleNone;   //不带分割线样式
    self.tempGroupTableView.rowHeight=45.0;
    
    self.navigationItem.rightBarButtonItem = self.editButtonItem;   //添加navigation按钮
    self.groupList = [DBManager selectTempGroup];   //获取分组信息
//    NSLog(@"-----%d",[groupList count]);
    [super viewDidLoad];
}

if (!cell)----当cell为空？真：假

//设置cell的高度

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

//返回自定义hrader
-(UIView*) tableView:(UITableView*)tableView viewForHeaderInSection:(NSInteger)section
{
    if (section==1) { //第二区
        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填充数据
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    //当第一个分区得最后一行
    if ((indexPath.section==0)&&(indexPath.row==[groupList count])) {
        static NSString *AddGroupViewCellIdentifier = @"AddGroupViewCell";
        
        UITableViewCell *cell=[[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:AddGroupViewCellIdentifier] autorelease];
        // key 说明性文字
        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";
    //使用自定义cell
    //查找SimpleTableIdentifier的cell，为空初始化
    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];

//设置cell右边箭头，v等等，有枚举变量可供选择
//    cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
    NSUInteger row = [indexPath row];
    cell.tag = row;
    [SimpleTableIdentifier release];
    return cell;
    
}

cell可删除

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

// 删除之后
- (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
    }   
}

//当前选中行设为非选中

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