清除UITableView底部多余的分割线

第一种方法:设置uitableView的footerView

1.在.m中加如下方法

-(void)setExtraCellLineHidden: (UITableView *)tableView
{
    UIView *view = [UIView new];
    view.backgroundColor = [UIColor clearColor];
    [tableView setTableFooterView:view];
    [view release];
}

 2.调用

- (void)viewDidLoad

{

    [super viewDidLoad];

    //设置tableView不能滚动

    [self.tableView setScrollEnabled:NO];

    //在此处调用一下就可以啦 :此处假设tableView的name叫:tableView

    [self setExtraCellLineHidden:self.tableView];

}

 

  在iOS4.3和iOS5.0中通过:值得注意的是在iOS4.3中可以直接设置footer为nil,但是在5.0不行,因为UITableView会默认生成一个Footer。(详见iOS Release Notes中的说明:Returning nil from the tableView:viewForHeaderInSection: method (or its footer equivalent) is no longer sufficient to hide a header. You must override tableView:heightForHeaderInSection: and return 0.0 to hide a header.)

plain类型的tableview当显示的数据很少时,下面的cell即使不显示数据也会有分割线,可以通过下面这个函数去掉多余的分割线。

- (void)setExtraCellLineHidden: (UITableView *)tableView
{
    UIView *view =[ [UIView alloc]init];
    view.backgroundColor = [UIColor clearColor];
    [tableView setTableFooterView:view];
    [view release];
}

 

第二种,隐藏原来的在cell中自定义:

 

if (cell == nil) {
    cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier] autorelease];

    // Drawing our own separatorLine here because I need to turn it off for the
    // last row. I can only do that on the tableView and on on specific cells.
    // The y position below has to be 1 less than the cell height to keep it from
    // disappearing when the tableView is scrolled.
    UIImageView *separatorLine = [[UIImageView alloc] initWithFrame:CGRectMake(0.0f, cell.frame.size.height - 1.0f, cell.frame.size.width, 1.0f)];
    separatorLine.image = [[UIImage imageNamed:@"grayDot"] stretchableImageWithLeftCapWidth:1 topCapHeight:0];
    separatorLine.tag = 4;

    [cell.contentView addSubview:separatorLine];

    [separatorLine release];
}

// Setup default cell setttings.
...
UIImageView *separatorLine = (UIImageView *)[cell viewWithTag:4];
separatorLine.hidden = NO;
...
// In the cell I want to hide the line, I just hide it.
seperatorLine.hidden = YES;
...

 设置tableview的样式为none

self.tableView.separatorStyle = UITableViewCellSeparatorStyleNone;
