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:15callback:^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:15callback:^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)directionfromExpansion:(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:UITableViewRowActionStyleDestructivetitle:@"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];}
