cell左滑加删除置顶功能 iOS

需求：开发下面这种样式，列表左滑有置顶和删除功能

- (BOOL)tableView:(UITableView *)tableView canEditRowAtIndexPath:(NSIndexPath *)indexPath {

    return YES;

}

 

-(UISwipeActionsConfiguration *)tableView:(UITableView *)tableView trailingSwipeActionsConfigurationForRowAtIndexPath:(NSIndexPath *)indexPath {

    UIContextualAction *delete = [UIContextualAction contextualActionWithStyle:UIContextualActionStyleNormal title:@"删除".ntes_localized handler:^(UIContextualAction * _Nonnull action, __kindof UIView * _Nonnull sourceView, void (^ _Nonnull completionHandler)(BOOL)) {

        [tableView setEditing:NO animated:YES];

        completionHandler(YES);

    }];

    UIContextualAction *top = [UIContextualAction contextualActionWithStyle:UIContextualActionStyleNormal title:@"置顶" handler:^(UIContextualAction * _Nonnull action, __kindof UIView * _Nonnull sourceView, void (^ _Nonnull completionHandler)(BOOL)) {

        NSLog(@"%@",@"置顶");

        [tableView setEditing:NO animated:YES];

        completionHandler(YES);

    }];

    top.backgroundColor = UIColorFromRGB(0xEEF7FF);

    

    UISwipeActionsConfiguration *config = [UISwipeActionsConfiguration configurationWithActions:@[delete,top]];

    //禁止滑动到底直接执行第一个按钮的事件

    config.performsFirstActionWithFullSwipe=NO;

    return config;

}

修改左滑按钮的样式

- (void)tableView:(UITableView *)tableView willBeginEditingRowAtIndexPath:(NSIndexPath *)indexPath {

    UITableViewCell *cell = (UITableViewCell *)[tableView cellForRowAtIndexPath:indexPath];

    [CATransaction begin];

    [CATransaction setDisableActions:YES];

    for (UIView * subView in cell.superview.subviews) {

        if ([subView isKindOfClass:NSClassFromString(@"UISwipeActionPullView")]) {

            for (UIView * sonView in subView.subviews) {

                if ([sonView isKindOfClass:NSClassFromString(@"UISwipeActionStandardButton")]) {

                    UIButton *aBtn = (UIButton *)sonView;

                    aBtn.titleLabel.font = kFont(14);

                    if (![aBtn.currentTitle isEqualToString:@"删除"]) {

                        [aBtn setTitleColor:UIColorFromRGB(0x3072F6) forState:UIControlStateNormal];

                    }

                }

            }

        }

    }

    [CATransaction commit];

}
