// 主要代碼

第一步：

- (BOOL)tableView:(UITableView *)tableView canEditRowAtIndexPath:(NSIndexPath *)indexPath {
    return YES;
}

第二步：
#pragma mark 在滑動手勢刪除某一行的時候，顯示出更多的按鈕

- (NSArray *)tableView:(UITableView *)tableView editActionsForRowAtIndexPath:(NSIndexPath *)indexPath

{

    // 添加一個刪除按鈕

    UITableViewRowAction *deleteRowAction = [UITableViewRowAction rowActionWithStyle:UITableViewRowActionStyleDestructive title:@"刪除" handler:^(UITableViewRowAction *action, NSIndexPath *indexPath) {

        NSLog(@"點(diǎn)擊了刪除");

        

        // 1. 更新數(shù)據(jù)

        //[_allDataArray removeObjectAtIndex:indexPath.row];

        // 2. 更新UI

        //[tableView deleteRowsAtIndexPaths:@[indexPath] withRowAnimation:UITableViewRowAnimationAutomatic];

    }];

//這個可以用來刷新特定行
       // [tableView reloadRowsAtIndexPaths:@[indexPath]withRowAnimation:UITableViewRowAnimationAutomatic];


    // 刪除一個置頂按鈕

    UITableViewRowAction *topRowAction = [UITableViewRowAction rowActionWithStyle:UITableViewRowActionStyleDefault title:@"置頂" handler:^(UITableViewRowAction *action, NSIndexPath *indexPath) {

        NSLog(@"點(diǎn)擊了置頂");

        

        // 1. 更新數(shù)據(jù)

        //[_allDataArray exchangeObjectAtIndex:indexPath.row withObjectAtIndex:0];

        

        // 2. 更新UI

        //NSIndexPath *firstIndexPath = [NSIndexPath indexPathForRow:0 inSection:indexPath.section];

        //[tableView moveRowAtIndexPath:indexPath toIndexPath:firstIndexPath];

    }];

    topRowAction.backgroundColor = [UIColor blueColor];

    

    // 添加一個更多按鈕

    UITableViewRowAction *moreRowAction = [UITableViewRowAction rowActionWithStyle:UITableViewRowActionStyleNormal title:@"更多" handler:^(UITableViewRowAction *action, NSIndexPath *indexPath) {

        NSLog(@"點(diǎn)擊了更多");

        

        [tableView reloadRowsAtIndexPaths:@[indexPath] withRowAnimation:UITableViewRowAnimationMiddle];

    }];

    moreRowAction.backgroundEffect = [UIBlurEffect effectWithStyle:UIBlurEffectStyleDark];

    

    // 將設(shè)置好的按鈕放到數(shù)組中返回

    return @[deleteRowAction, topRowAction, moreRowAction];

}

-(void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath{
    editingStyle = UITableViewCellEditingStyleDelete;
}

第三步：

-(void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath{
    editingStyle = UITableViewCellEditingStyleDelete;
}

第四步：（如果需要更改 刪除或編輯 按鈕的高度 寬度的話，在cell中重寫此方法）

    // 改變滑動刪除按鈕樣式
    - (void)layoutSubviews {
        [super layoutSubviews];
        for (UIView *subView in self.subviews){
            if([subView isKindOfClass:NSClassFromString(@"UITableViewCellDeleteConfirmationView")]) {
                CGRect cRect = subView.frame;
                cRect.origin.y = self.contentView.frame.origin.y+10;
                cRect.size.height = self.contentView.frame.size.height - 10;
                subView.frame = cRect;
                
                UIView *confirmView=(UIView *)[subView.subviews firstObject];
                // 改背景顏色
                confirmView.backgroundColor=[UIColor colorWithRed:254/255.0 green:85/255.0 blue:46/255.0 alpha:1];
                for(UIView *sub in confirmView.subviews){
                    if([sub isKindOfClass:NSClassFromString(@"UIButtonLabel")]){
                        UILabel *deleteLabel=(UILabel *)sub;
                        // 改刪除按鈕的字體
                        deleteLabel.font=[UIFont boldSystemFontOfSize:15];
                        // 改刪除按鈕的文字
                        deleteLabel.text=@"刪除";
                    }
                }
                break;
            }
        }
    }
