从 UIVIewController 向 SKScene 传递数据
Passing Data to SKScene from UIVIewController
我想要完成的是(至少应该..)非常简单:我想呈现一个 SKScene
,其中包含呈现此场景的 UIViewController
中的数据.换句话说,我有一个变量 chapter
声明如下:
#import <UIKit/UIKit.h>
#import <SpriteKit/SpriteKit.h>
@interface ViewController : UIViewController
@property (nonatomic) NSInteger chapter;
@end
我已经用日志测试了实际上声明了变量章节(在我的例子中,我只是将它作为 4 进行测试)。
这是我的 ViewController.m 文件以及我如何呈现我的场景:
- (void)viewDidLoad {
[super viewDidLoad];
.
.
.
// Configure the view.
SKView *skView = (SKView *)self.view;
if (!skView.scene) {
skView.showsFPS = YES;
skView.showsNodeCount = YES;
// Create and configure the scene.
scene = [OLevel sceneWithSize:CGSizeMake(skView.bounds.size.width, skView.bounds.size.height)];
scene.scaleMode = SKSceneScaleModeResizeFill;
// Set the SKScene chapter #
scene.chapter = self.chapter; // <<<< NOT WORKING?
NSLog(@"CHAP TO PASS: %u", self.chapter);
NSLog(@"CHAP RECEIVED: %u", scene.chapter);
// Present the scene.
[skView presentScene:scene];
}
场景定义如下,viewDidLoad 是上面显示的那个:(我有它 subclassed)
@interface ViewController () {
OLevel *scene;
}
@end
@implementation ViewController
- (void)viewDidLoad {
[super viewDidLoad];
.
.
.
这是我的OLevel.hclass:
#import <SpriteKit/SpriteKit.h>
#import <GameplayKit/GameplayKit.h>
@interface OLevel : SKScene <SKPhysicsContactDelegate, GKAgentDelegate>
@property (nonatomic) NSInteger chapter;
@end
还有我的OLevel.m*:
- (id)initWithSize:(CGSize)size {
if (self = [super initWithSize:size]) {
NSLog(@"Creating scene");
NSLog(@"CHAP: %u", self.chapter);
[self setUpScene];
}
return self;
}
我很困惑为什么这种方法不起作用。我已将 ViewController 中的 属性 设置为所需的章节值,然后我告诉 Olevel 什么值它是并将它自己的章节 属性 设置为这样的值,然后正确呈现场景。为什么我继续得到0??

我知道这个问题已经得到回答here,使用的方法与我在寻找答案之前最初使用的方法相同,但我还没有让它起作用..
如果有人知道我做错了什么,请帮助我。
您也可以尝试使用 NSNotificationCenter 传递您的数据
[[NSNotificationCenter defaultCenter] addObserver:self
selector:@selector(receiveTestNotification:)
name:@"TestNotification"
object:nil];
NSDictionary *userInfo = [NSDictionary dictionaryWithObject:myObject forKey:@"someKey"];
[[NSNotificationCenter defaultCenter] postNotificationName: @"TestNotification" object:nil userInfo:userInfo];
您使用错误的语法初始化场景,没有类型:
...
// Create and configure the scene.
OLevel *scene = [OLevel sceneWithSize:CGSizeMake(skView.bounds.size.width, skView.bounds.size.height)];
scene.scaleMode = SKSceneScaleModeResizeFill;
// Set the SKScene chapter #
scene.chapter = self.chapter;
...
如果你愿意,你也可以使用第
章子类化 init 方法
OLevel.h:
@interface GameScene : SKScene <SKPhysicsContactDelegate, GKAgentDelegate>
@property (nonatomic) NSInteger chapter;
-(id)initWithSize:(CGSize)size chapter:(NSInteger)chapter;
+(id)sceneWithSize:(CGSize)size chapter:(NSInteger)chapter;
@end
OLevel.m:
#import "GameScene.h"
@implementation GameScene
-(id)initWithSize:(CGSize)size chapter:(NSInteger)chapter {
if (self = [super initWithSize:size]) {
self.chapter = chapter;
//some custom code here
NSLog(@"Creating scene");
NSLog(@"CHAP: %ld", (long)self.chapter);
}
return self;
}
+(id)sceneWithSize:(CGSize)size chapter:(NSInteger)chapter {
return ((GameScene *)[[self alloc] initWithSize:size chapter:chapter]);
}
-(void)didMoveToView:(SKView *)view {
...
}
}
在这种情况下,您可以将场景创建为:
// Create and configure the scene.
scene = [OLevel sceneWithSize:CGSizeMake(skView.bounds.size.width, skView.bounds.size.height) chapter:self.chapter];
scene.scaleMode = SKSceneScaleModeResizeFill;
