编辑和删除按钮UITableView [英] Edit and Delete Button UITableView

问题描述

我可以将UITableView置于编辑模式并显示删除按钮。我如何在删除按钮旁边添加一个蓝色的编辑按钮？

I can put a UITableView into edit mode and show the delete button. How would I add a blue "Edit" button beside the delete button?

就像在ios6中向左滑动邮件一样，除了邮件应用程序显示更多之外，我想要一个编辑按钮。

Just like swiping left in the mail in ios6, except the mail app shows "More", I want a "Edit" button.

推荐答案

这不是Apple的 UITableViewCell 的标准功能。 -您将需要使用自己的滑动识别器来创建自己的 UITableViewCell 子类。

This isn't a feature that comes standard with Apple's UITableViewCell - you're going to need to make your own subclass of UITableViewCell with your own swipe recognizer.

此GitHub项目是一个不错的开始-使用它，您应该可以使用以下代码：

This GitHub project is a great start - using it, you should be able to use this code:

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
    static NSString *cellIdentifier = @"Cell";

    SWTableViewCell *cell = (SWTableViewCell *)[tableView dequeueReusableCellWithIdentifier:cellIdentifier];

    if (cell == nil) {
        NSMutableArray *rightUtilityButtons = [NSMutableArray new];

        [rightUtilityButtons sw_addUtilityButtonWithColor:
                    [UIColor colorWithRed:0.78f green:0.78f blue:0.8f alpha:1.0]
                    title:@"More"];
        [rightUtilityButtons sw_addUtilityButtonWithColor:
                    [UIColor colorWithRed:1.0f green:0.231f blue:0.188 alpha:1.0f] 
                        title:@"Delete"];

        cell = [[SWTableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle 
                    reuseIdentifier:cellIdentifier 
                    containingTableView:_tableView // For row height and selection
                    leftUtilityButtons:nil 
                    rightUtilityButtons:rightUtilityButtons];
        cell.delegate = self;
    }
...

return cell;

然后为该单元实现委托方法：

You then implement the delegate method for the cell:

- (void)swippableTableViewCell:(SWTableViewCell *)cell didTriggerRightUtilityButtonWithIndex:(NSInteger)index {
    switch (index) {
        case 0:
            NSLog(@"More button was pressed");
            break;
        case 1:
        {
            // Delete button was pressed
            NSIndexPath *cellIndexPath = [self.tableView indexPathForCell:cell];

            [_testArray removeObjectAtIndex:cellIndexPath.row];
            [self.tableView deleteRowsAtIndexPaths:@[cellIndexPath] 
                    withRowAnimation:UITableViewRowAnimationAutomatic];
            break;
        }
        default:
            break;
    }
}
