只有当表格加载并向下滚动到最后一行时，桌面顶部和表格标题之间仍存在一些差距？ [英] Some Gap remains between Table Top and Table Header only when table loads and scrolled down to the last row?

问题描述

编辑：它工作正常，但仍然当表得到负载表顶部和表头之间有一些差距abt 30 pxcls（或1行）..？

It works fine, But still when the table get Loads Some gap remains between table top and table header abt 30 pxcls(or 1 row) ..?

请帮助....

我滚动它工作正常。所有表行都是滚动的，表头是固定的。
但是当我滚动到表的末尾时，它失去了修复的属性。我的意思是边界滚动。我想绝对冻结它。在边界条件下，它会失去桌子的顶部位置并滑动大约20个pxcls。

I am scrolling it works fine. All the table rows are scrolling and table header is fixed. But when I scroll to end of the table it looses its property of fix. I mean is boundry scrolling. I want to freeze it absolutely. At the boundary condition it looses the top position of the table and slides about 20 pxcls.

//Header Format starting
- (CGFloat)tableView:(UITableView *)tableView heightForHeaderInSection:(NSInteger)section
{
    return 20.0;
}

- (UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section     
{
    if (tableView.tableHeaderView) { // header was already created... go away
        return tableView.tableHeaderView;
    }

    CGFloat width = 300.0f;
    CGRect rectArea = CGRectMake(10.0f, 5.0f, width, 25.0);

    tableView.tableHeaderView = [[[UIView alloc] initWithFrame:rectArea] autorelease];

    //UIColor *orange =  [UIColor colorWithRed:(255.0f/255.0f) green:(228.0f/255.0f) blue:0.0f alpha:1.0f];

    [tableView.tableHeaderView setBackgroundColor:[UIColor grayColor]];

    rectArea = CGRectMake(02.0f, 1.0f, width, 20.0);
    UILabel *lbl = [[UILabel alloc] initWithFrame:rectArea];
    lbl.text = NSLocalizedString(@"Bill Total", @"");
    lbl.textAlignment = UITextAlignmentLeft;
    //lbl.font = [UIFont systemFontOfSize:13.0f];
    lbl.font = [UIFont fontWithName:@"Courier New" size:14];
    lbl.font=[UIFont italicSystemFontOfSize:14];
    lbl.textColor = [UIColor blackColor];
    lbl.backgroundColor = [UIColor clearColor];
    lbl.numberOfLines = 2.0f;
    lbl.lineBreakMode = UILineBreakModeWordWrap;
    //[lbl sizeToFit];

    [tableView.tableHeaderView addSubview:lbl];
    [lbl release];

    // self.table.tableHeaderView.layer.cornerRadius = 6.0f;

    return table.tableHeaderView;
}

推荐答案

如果我正确理解你的问题，听起来你只需要桌子不要反弹。如果是这种情况，您需要做的就是在viewDidLoad函数中设置 yourTable.bounces = NO; 。如果你使用一个来布局你的表，那么或者取消选中NIB中的Bounces选项。

If I understand your question correctly, it sounds like you just need the table not to bounce. If that's the case, all you need to do is set yourTable.bounces = NO; in your viewDidLoad function. Either that or uncheck the "Bounces" option in the NIB if you used one to layout your table.

以下是修复编辑中提到的问题的方法...您需要将以下对tableView.headerView的引用替换为对未被传递的新视图的引用进入委托方法。

Here's how to fix the problem you mentioned in your edit... You need to replace the following references to tableView.headerView with references to a new view that's not being passed into the delegate method.

    UIView *headerView = [[[UIView alloc] initWithFrame:rectArea] autorelease];
    //...    
    [headerView setBackgroundColor:[UIColor grayColor]];
    //...
    [headerView addSubview:lbl];
    //...
    return headerView;

我试过了，它为我做了诀窍。希望有所帮助。

I tried it and it did the trick for me. Hope that helps.
