推荐答案

您可以使用以下任一代码片段来隐藏 UITableView 的标准分隔线.添加自定义分隔符的最简单方法是添加一个简单的UIView 1px 高度:

You can hide UITableView's standard separator line by using any one of the below snippets of code. The easiest way to add a custom separator is to add a simple UIView of 1px height:

UIView* separatorLineView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 320, 1)];
separatorLineView.backgroundColor = [UIColor clearColor]; // set color as you want.
[cell.contentView addSubview:separatorLineView];

或

    self.tblView=[[UITableView alloc] initWithFrame:CGRectMake(0,0,320,370) style:UITableViewStylePlain];
    self.tblView.delegate=self;
    self.tblView.dataSource=self;
    [self.view addSubview:self.tblView];

    UIView *v = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 320, 10)];
    v.backgroundColor = [UIColor clearColor];
    [self.tblView setTableHeaderView:v];
    [self.tblView setTableFooterView:v];
    [v release];

或

- (float)tableView:(UITableView *)tableView heightForFooterInSection:(NSInteger)section {
    // This will create a "invisible" footer
    return 0.01f;
}

- (UIView *)tableView:(UITableView *)tableView viewForFooterInSection:(NSInteger)section
{
    // To "clear" the footer view
    return [[UIView new] autorelease];
}

还要检查 nickfalk 的回答，它非常简短而且也很有帮助.你也应该试试这一行，

And also check nickfalk's answer, it is very short and helpful too. And you should also try this single line,

self.tableView.tableFooterView = [[UIView alloc] init];

不确定，但它适用于我检查过的所有 iOS 版本，iOS 5 及更高版本，直到 iOS 7.

Not sure but it's working in all the version of iOS that I checked, with iOS 5 and later, up to iOS 7.
