将信息从 collectionView 传递到 gameScene

问题描述：

我使用 SpriteKit(GameScene 和 GameViewController)和 Objective-C 创建了一个游戏.那里一切正常.在同一个应用程序中，我在使用 CollectionView 的故事板中创建了一个 UIViewController 和第二个 viewController.我有 collectionView 加载数组.

I have created a game using SpriteKit (GameScene and GameViewController) and Objective-C. Everything there works fine. Within the same App I have created a UIViewController and a second viewController in storyboard that uses CollectionView. I have the collectionView loading the array.

我希望能够点击 collectionView Cell 并让它打开游戏视图.我能做的.但是，我想将 collectionView 中的一些信息传递给 GameScene，以便我可以加载背景图像和其他信息，以便为每个 collectionViewCell 个性化 GameScene.

I want to be able to tap on a collectionView Cell and have it open the gameView. Which I can do. However I would like to pass some information from the collectionView to the GameScene so I can load the background image and other information to individualize the GameScene for each collectionViewCell.

这是我的 collectionView 代码

Here is my code for the collectionView

#import "collectionViewController.h"
#import "GameScene.h"
#import "GameViewController.h"
@implementation collectionViewController
@synthesize animalArray,theImage,StringPicture,myCell;

-(void) viewDidLoad {
    [super viewDidLoad];
   animalArray = [NSArray arrayWithObjects:@"Cat.png",
                     @"image1.png",
                     @"image2.png",
                     @"image3.png",
                    ,nil];
}

-(NSInteger) numberOfSectionsInCollectionView:(UICollectionView *)collectionView {
    return 1;
}




-(NSInteger) collectionView:(UICollectionView *)collectionView numberOfItemsInSection:(NSInteger)section {
    return animalArray.count;

}

-(UICollectionViewCell *)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath {
    myCell = [collectionView dequeueReusableCellWithReuseIdentifier:@"cell" forIndexPath:indexPath];

    UIImage *images;
    long row = [indexPath row];
    images = [UIImage imageNamed:animalArray[row]];

    myCell.image1.image = images;

    return myCell;
}




-(void) collectionView:(UICollectionView *)collectionView didDeselectItemAtIndexPath:(NSIndexPath *)indexPath {

    NSLog(@"indexPath.row:%ld",(long)indexPath.row);


    if (indexPath.row==1) {
        UIStoryboard *sb = [UIStoryboard storyboardWithName:@"Main" bundle:nil];
        UIViewController *vc = [sb instantiateViewControllerWithIdentifier:@"GameSceneOne"];
       vc.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;
        NSLog(@"mycell.image1.image:%@",myCell.image1.image);

        [self presentViewController:vc animated:YES completion:NULL];


    }

    if (indexPath.row==2) {
        UIStoryboard *sb = [UIStoryboard storyboardWithName:@"Main" bundle:nil];
        UIViewController *vc = [sb instantiateViewControllerWithIdentifier:@"GameSceneOne"];
        vc.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;
        [self presentViewController:vc animated:YES completion:NULL];

    }
}

我尝试将 GameScene.image 分配给 vc.image，但一个是 GameView，另一个是 UIViewController，所以我不能这样做.

I have tried assigning the GameScene.image to the vc.image but one is a GameView and the other is a UIViewController so I can't do that.

我尝试过使用 segue，但仍然无法将信息传递给另一个.

I have tried using a segue but still the information can't be passed from on to the other.

我该怎么做?

答

有几种方法可以做到这一点.其中之一是使用 NSUserDefaults.

Couple of ways to do this. One of them is using NSUserDefaults.

要将数据存储在 NSUserDefaults 中，请执行以下操作:

To store data in NSUserDefaults, do this:

// object can be almost anything. Strings, arrays, dictionaries...

NSString *object = @"WellDone";

NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
[defaults setObject:object forKey:@"Hamburger"];
[defaults synchronize];

要读取 NSUserDefaults，请执行以下操作:

To read NSUserDefaults, do this:

NSString *myString = [[NSUserDefaults standardUserDefaults] objectForKey:@"Hamburger"];

关键在于您使用的密钥与创建时相同.

The key being that you use the same key as when you created it.

当然，请阅读文档(废话，废话，废话).

And of course, read the docs (blah,blah, blah).
