滑动UITableViewCell出现多个按钮

iOS > = 5.0使用第三方效果图

iOS> = 8.0使用系统方法效果图

MGSwipeTableCell(Github上的三方库)- iOS >= 5.0

直接使用比较简单 通过代码看一下



首先签这个协议MGSwipeTableCellDelegate

添加左边按钮方法

- (NSArray *)btnLeftCount:(int)count
{
    NSMutableArray *result = [NSMutableArray array];
    UIColor *colors[3] = {[UIColor greenColor],
        [UIColor colorWithRed:0 green:0x99/255.0 blue:0xcc/255.0 alpha:1.0],
        [UIColor colorWithRed:0.59 green:0.29 blue:0.08 alpha:1.0]};;
    for (int i = 0; i < count; i ++) {
        // 按钮提供了几个方法, 可以点进去看一看
        MGSwipeButton *btn = [MGSwipeButton buttonWithTitle:@"" backgroundColor:colors[i] padding:15
callback:^BOOL(MGSwipeTableCell *sender) {
            return YES;
        }];
        // 把按钮加到数组中
        [result addObject:btn];
    }
    return result;
}

添加右边按钮的方法

- (NSArray *)btnRightCount:(int)count
{
    NSMutableArray *result = [NSMutableArray array];
    NSArray *titleArray = @[@"删除", @"标记未读"];
    UIColor *color[2] = {[UIColor redColor], [UIColor lightGrayColor]};
    for (int i = 0; i < count; i ++) {
        MGSwipeButton *btn = [MGSwipeButton buttonWithTitle:titleArray[i] backgroundColor:color[i] padding:15
callback:^BOOL(MGSwipeTableCell *sender) {
            BOOL autoHide = i != 0;
            return autoHide;
        }];
        // 把按钮加到数组中
        [result addObject:btn];
    }
    return result;
}

重用池可以这样写

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *cellID = @"cellId";
    // 这里如果MGSwipeTableCell是足够你使用的, 你可以直接使用
    // 或者自定义创建cell继承于MGSwipeTableCell, 像我下面代码这样
    XTCustomCell *cell = [tableView dequeueReusableCellWithIdentifier:cellID];
    if (!cell) {
        cell = [[XTCustomCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:cellID];
    }
    cell.label.text = [NSString stringWithFormat:@"%ld------%@", (long)indexPath.row, self.arrayTest[indexPath.row]];
    cell.label.font = [UIFont systemFontOfSize:20];
    // 指定代理人
    cell.delegate = self;
    // NO: 只有单个可以滑动 , YES: 多个可以滑动
    cell.allowsMultipleSwipe = NO;
    return cell;
}

添加按钮

-(NSArray*) swipeTableCell:(MGSwipeTableCell*) cell swipeButtonsForDirection:(MGSwipeDirection)direction
             swipeSettings:(MGSwipeSettings*) swipeSettings expansionSettings:(MGSwipeExpansionSettings*) expansionSettings;
{
    if (direction == MGSwipeDirectionRightToLeft) {

        return [self btnRightCount:2];
    }
    else {
        return [self btnLeftCount:3];

    }
}

按钮的点击代理方法

-(BOOL) swipeTableCell:(MGSwipeTableCell*) cell tappedButtonAtIndex:(NSInteger) index direction:(MGSwipeDirection)direction
fromExpansion:(BOOL) fromExpansion
{

    switch (direction) {
        case MGSwipeDirectionLeftToRight: {
            if (index == 0) {
                NSLog(@"right ------- 0");
            }else{
                NSLog(@"right ------- 1");
            }
            break;
        }
        case MGSwipeDirectionRightToLeft: {
            if (index == 0) {
                NSLog(@"left ------- 0");
                // 这里简单的做了个删除操作
                NSIndexPath * path = [_tableView indexPathForCell:cell];
                [_arrayTest removeObjectAtIndex:path.row];
                [_tableView deleteRowsAtIndexPaths:@[path] withRowAnimation:UITableViewRowAnimationLeft];
                return NO;
            }else{
                NSLog(@"left ------- 1");
            }
            break;
        }
    }
    return YES;
}

iOS8 之后也提供了类似的实现

- (NSArray *)tableView:(UITableView *)tableView editActionsForRowAtIndexPath:(NSIndexPath *)indexPath
{
    UITableViewRowAction *deleteRowAction = [UITableViewRowAction rowActionWithStyle:UITableViewRowActionStyleDestructive
title:@"删除" handler:^(UITableViewRowAction * _Nonnull action, NSIndexPath * _Nonnull indexPath) {
        [self.arrayTest removeObjectAtIndex:indexPath.row];
        [self.tableView deleteRowsAtIndexPaths:@[indexPath] withRowAnimation:UITableViewRowAnimationAutomatic];
    }];

    UITableViewRowAction *topRowAction = [UITableViewRowAction rowActionWithStyle:UITableViewRowActionStyleDefault title:@"置顶"
handler:^(UITableViewRowAction * _Nonnull action, NSIndexPath * _Nonnull indexPath) {
        [self.arrayTest exchangeObjectAtIndex:indexPath.row withObjectAtIndex:0];
        NSIndexPath *firstIndexPath = [NSIndexPath indexPathForRow:0 inSection:indexPath.section];
        [tableView moveRowAtIndexPath:indexPath toIndexPath:firstIndexPath];
    }];
    topRowAction.backgroundColor = [UIColor blueColor];

    UITableViewRowAction *moreRowAction = [UITableViewRowAction rowActionWithStyle:UITableViewRowActionStyleNormal title:@"更多"
 handler:^(UITableViewRowAction * _Nonnull action, NSIndexPath * _Nonnull indexPath) {
        [self.tableView reloadRowsAtIndexPaths:@[indexPath] withRowAnimation:UITableViewRowAnimationMiddle];
    }];
    return @[deleteRowAction,topRowAction,moreRowAction];
}
