我有一个非常具体的问题。我是Xcode的新手，但到目前为止，我能够使用标签栏控制器创建一个应用程序，其中一个标签控制器是tableviewcontroller。我在tableviewcontroller中显示表格单元格没有问题，甚至点击其中的任何一个都是segueing到detailviewcontroller，其中表格单元格有广泛的信息，但我的问题是当我试图通过点击菜单按钮，我想要一个标签时更进一步以及要显示的菜单图像。我得到一个空白的屏幕。我甚至看不到标题，甚至没有谈论推动图像。 我认为问题在于通过一个级别推送信息。 这是TableViewController.h：
#import <UIKit/UIKit.h>
@interface TableViewController1 : UITableViewController
@property (nonatomic, strong) NSArray *Menus;
@property (nonatomic, strong) NSArray *Images;
@property (nonatomic, strong) NSArray *Title;
@property (nonatomic, strong) NSArray *Description;
@end
和TableViewController.m：
#import "TableViewController1.h"
#import "TableCell1.h"
#import "DetailViewController.h"
#import "MenuViewController.h"
@interface TableViewController1 ()
@end
@implementation TableViewController1

self = [super initWithStyle:style];
if (self) {
// Custom initialization
}
return self;
}

{
[super viewDidLoad];
// Uncomment the following line to preserve selection between presentations.
// self.clearsSelectionOnViewWillAppear = NO;
// Uncomment the following line to display an Edit button in the navigation bar for this view controller.
// self.navigationItem.rightBarButtonItem = self.editButtonItem;
self.tableView.separatorColor = [UIColor colorWithRed:0/255.0 green:181/255.0 blue:0/255.0 alpha:0.5];
UIBarButtonItem *NewBackButton = [[UIBarButtonItem alloc] initWithTitle:@"Back" style:UIBarButtonItemStyleBordered target:nil action:nil];
[[self navigationItem] setBackBarButtonItem:NewBackButton];
_Title = @[@"Velvet Sport Villa",
@"GQ",
