如何使用自定义单元格整个过程实现可扩展表？

Question

我想在用户点击按钮时自动打开同一视图中的另一个表时实现可扩展表。

这是我的.m文件 strong text

#import "MenuVc.h"
#import "Reachability.h"
#import "YRDropdownView.h"
#import "MenuFirstCell.h"

@interface MenuVc ()

@end

@implementation MenuVc

- (void)viewDidLoad {
    [super viewDidLoad];
    // Do any additional setup after loading the view from its nib.
    menuArr=[[NSMutableArray alloc]init];
     fvd=[[NSMutableArray alloc]init];
     secondNEw=[[NSMutableArray alloc]init];
  //  [self.firstmenutble registerClass:[UITableViewCell class] forCellReuseIdentifier:@"Cell"];

      [self.firstmenutble registerNib:[UINib nibWithNibName:@"MenuFirstCell" bundle:nil] forCellReuseIdentifier:@"Cell"];

    [self countries_delay];


    _sub_menu=[[Submenu alloc]initWithNibName:@"Submenu" bundle:nil];

    [self.view addSubview:_sub_menu.view];
    _sub_menu.delegate=self;
    _sub_menu.view.hidden=YES;
    self.sub_menu.view.frame = CGRectMake(156, 45,156 , 317);
    [self.view addSubview:self.sub_menu.view];



    //[self netcheck];
}




- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {


    return 1;
}


- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {

    return menuArr.count;

}

-(UITableViewCell*)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {

    MenuFirstCell * cell = [tableView dequeueReusableCellWithIdentifier:@"Cell" forIndexPath:indexPath];




      //  UITableViewCell * cell = [tableView dequeueReusableCellWithIdentifier:@"Cell" forIndexPath:indexPath];

        cell.name.text=[[menuArr objectAtIndex:indexPath.row] objectForKey:@"name"];
        cell.name.font =[UIFont fontWithName:@"PT Sans" size:14];
    cell.nextbtn.tag = indexPath.row;
    [cell.nextbtn addTarget:self action:@selector(btnClick:) forControlEvents:UIControlEventTouchUpInside];

        return cell;

    }







- (IBAction)btnClick:(id)sender
{


//    
//    if (self.sub_menu.view.frame.origin.x == 156)
//    {
//                    _sub_menu.view.hidden=NO;
//            //
//            //    CATransition *applicationLoadViewIn = [CATransition animation];
//            //    //
//            //       [applicationLoadViewIn setDuration:0.5];

这是我的.h文件 -

#import "Submenu.h"
#import <UIKit/UIKit.h>
@protocol Scrap_menuDelegate <NSObject>
-(void)HomeBtn;
@end
@interface MenuVc : UIViewController<UITableViewDataSource, UITableViewDelegate,submenu_menuDelegate>
{

    NSMutableArray *menuArr;


    IBOutlet UIActivityIndicatorView *activityView;

      NSMutableArray *fvd;
    NSMutableArray *secondNEw;

}
@property(weak,nonatomic)id delegate;


@property(nonatomic, strong) Submenu *sub_menu;


@property (strong, nonatomic) IBOutlet UIView *firstview;
@property (strong, nonatomic) IBOutlet UITableView *firstmenutble;



- (IBAction)HomeBtn:(id)sender;

@end

请使用此代码扩展表来实现。
