我想要完成的是(至少应该......)非常简单:我想提供一个SKScene
,其中包含我在展示此场景的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
我已经使用日志测试了变量章实际上已声明(在我的情况下,我只是用它测试为4)。
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];
}
将场景定义如下,viewDidLoad如上所示:(我有子类)
@interface ViewController () {
OLevel *scene;
}
@end
@implementation ViewController
- (void)viewDidLoad {
[super viewDidLoad];
.
.
.
这是我的 OLevel.h 类:
#import <SpriteKit/SpriteKit.h>
#import <GameplayKit/GameplayKit.h>
@interface OLevel : SKScene <SKPhysicsContactDelegate, GKAgentDelegate>
@property (nonatomic) NSInteger chapter;
@end
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,然后告诉我 Olevel 它的值是什么,并将它自己的章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用here回答了我在寻找答案之前最初使用过的方法,但我还没有让它发挥作用..
如果有人知道我做错了什么,请帮助我。

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;
...
如果您愿意,也可以使用章节
继承init方法<强> OLevel.h 强>:
@interface GameScene : SKScene <SKPhysicsContactDelegate, GKAgentDelegate>
@property (nonatomic) NSInteger chapter;
-(id)initWithSize:(CGSize)size chapter:(NSInteger)chapter;
+(id)sceneWithSize:(CGSize)size chapter:(NSInteger)chapter;
@end
<强> OLevel.m 强>:
#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;

您还可以尝试使用NSNotificationCenter
传递数据[[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];
