在UITableView中更新部分页脚标题而不重新加载 [英] Update section footer title in UITableView without reloading

问题描述

我希望能够以编程方式更新表格视图中部分的页脚标题，同时我通过键盘输入文本。当我单击一个单元格以使其详细的文本视图可编辑时，键盘出现，所以我想更新页脚标题而不从数据源重新加载。

I would like to be able to programmatically update the footer title of a section inside a table view, while I am typing text through a keyboard. The keyboard appears when I click on a cell to make its detailedText view editable, so I would like to update the footer title without reloading from the data source.

实际上，如果我这样做，键盘会消失，所以它不是一种很好的互动形式。我无法找到解决这个问题的好方法......有什么建议吗？

In fact, if I did this, the keyboard would disappear so it is not a good form of interaction. I've not been able to find a good solution to this problem... any suggestions?

谢谢

推荐答案

如果你有分组表，你可以使用：

If you have groupped table, you can use:

- (UIView *)tableView:(UITableView *)tableView viewForFooterInSection:(NSInteger)section {
    yourLabel = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, 320, 17)]; //I'm not sure about the frame...
    yourLabel.font = [UIFont systemFontOfSize:16];
    yourLabel.shadowColor = [UIColor whiteColor];
    yourLabel.shadowOffset = CGSizeMake(0, 1);
    yourLabel.textAlignment = UITextAlignmentCenter;
    yourLabel.textColor = RGB(76, 86, 108);
    yourLabel.backgroundColor = [UIColor clearColor];
    yourLabel.opaque = NO;
    return yourLabel;
}

声明 yourLabel in你的 .h 文件。然后，你可以通过

Declare yourLabel in your .h file. Then, you can access it via

yourLabel.text = @"whatever you want";

请检查是否有效：）
