objective-c Table 推送视图

Question

我目前正在处理推送 table 视图控制器我的 table 视图上有一个导航控制器。我需要让它为我的类别加载推送视图：电影、电视节目等。我做了第二个 Table-View 控制器来加载 table Push View 我不确定我需要做什么才能完成这个？！... 这是我使用数组加载项目的第二个控制器的代码；

#import "itemViewController.h"

@interface itemViewController () <UIAlertViewDelegate>

@property (nonatomic) NSMutableArray *items;

@end

@implementation itemViewController

//Buttons and Cells View.
- (void)viewDidLoad {
    [super viewDidLoad];

       //Edit/Done Button.
    self.navigationItem.leftBarButtonItem = [[UIBarButtonItem alloc] initWithTitle:@"Edit" style:UIBarButtonItemStylePlain target:self action:@selector(toggleEditing:)];
    //Add Item.
    self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemAction target:self action:@selector(addNewItem:)];
    
    
    
   //The Stuff Below I need to turn into a switch statement to load the right one how can I accomplish this?
//movie
    self.items = @[@{@"name" : @"Avatar"},@{@"name" : @"SharkNado"},@{@"name" : @"Kung Fu Panda"}].mutableCopy;
    self.navigationItem.title = @"Movies";
    /*
//Tv Shows
    self.items = @[@{@"name" : @"Avatar the last Airbender"},@{@"name" : @"Reguluar Show"},@{@"name" : @""}].mutableCopy;
    self.navigationItem.title = @"TV Shows";
    
//Restaurants
    self.items = @[@{@"name" : @""},@{@"name" : @""},@{@"name" : @""}].mutableCopy;
    self.navigationItem.title = @"Restaurants";
    
//Concert Venues
    self.items = @[@{@"name" : @""},@{@"name" : @""},@{@"name" : @""}].mutableCopy;
    self.navigationItem.title = @"Concert Venues";

//Video Games
    self.items = @[@{@"name" : @""},@{@"name" : @""},@{@"name" : @""}].mutableCopy;
    self.navigationItem.title = @"Video Games";
