iphone - 別のビューから NSMutableArray にデータを追加する

Question

MenuViewController.h から NSMutableArray *menu を読みたいのですが、試すのにうんざりしています。これは私のコードです：

//  ViewController.h

#import <UIKit/UIKit.h>

@interface ViewController : UIViewController

@end




//  ViewController.m


#import "ViewController.h"
#import "MenuViewController.h"

@interface ViewController ()

@end

@implementation ViewController

#pragma mark - view Did Load, View Will Appear & didReceiveMemoryWarning

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.

}

-(void)viewWillAppear:(BOOL)animated {

        MenuViewController *menuView = [[MenuViewController alloc] init];
    [self.view addSubview:menuView.view]; // this line is new

    NSLog(@"%@", menuView.self.menu);
    [menuView.menu addObject:@"Darommmm"];

    NSLog(@"%@", menuView.menu);

    [menuView.tableView reloadData];


}

- (void)didReceiveMemoryWarning
{
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}

@end

これが私のviewController.mと.hのコードです。以下に、MenuViewController.h と .m のコードを示します。

//  MenuViewController.h


#import <UIKit/UIKit.h>

@interface MenuViewController : UIViewController <UITableViewDataSource, UITableViewDelegate>

@property (nonatomic, retain) IBOutlet UITableView *tableView;
@property (nonatomic, retain) NSMutableArray *menu;
@property (nonatomic, retain) NSMutableArray *sections;

@end


//  MenuViewController.m

#import "MenuViewController.h"

@interface MenuViewController ()

@end

@implementation MenuViewController

@synthesize menu, sections, tableView;

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
    if (self) {
        // Custom initialization
    }
    return self;
}

#pragma mark - View Did load, View Will Appear & didReceiveMemoryWarning

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view from its nib.



    // set background to transparent + no seperator 
    [self.tableView setSeparatorStyle:UITableViewCellSeparatorStyleNone];
    self.tableView.backgroundColor = [UIColor clearColor];


    // allocate the mutable array for our menu
    self.menu       = [[NSMutableArray alloc] init];


    // standard menu items to our object
    [self.menu addObject:@"Dashboard"];
    [self.menu addObject:@"Chats"];
    [self.menu addObject:@"Visitors"];
    [self.menu addObject:@"Log Out"];
}

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
    // Return the number of rows in the section.
    return [self.menu count];
}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *CellIdentifier = @"Cell";
    UITableViewCell *cell = [self.tableView dequeueReusableCellWithIdentifier:CellIdentifier];

    if (!cell) {

        cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
    }

    cell.textLabel.text = [self.menu objectAtIndex:indexPath.row];

    cell.textLabel.textColor = [UIColor whiteColor];
    UIImageView *bg = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"sidebarcell"]];
    [bg setFrame:CGRectMake(0, 0, 161.5, 42.5)];
    // Configure the cell...
    cell.backgroundView = bg;

    return cell;
}

menuView.self.menu を NSLog しようとすると (null) が表示されます。皆さんが私を助けてくれることを願っています! 乾杯。
