奇妙な行動の原因を見つけようとしています。私の SpriteKit シーンには、プロパティとして SKLabelNode があります。SKLabelNode は、 levelSelected というメソッドで初期化されます。
-(void)levelSelected{
SKSpriteNode* bar = [SKSpriteNode spriteNodeWithColor:[UIColor colorWithHue:0.566f saturation:0.787f brightness:0.792f alpha:1] size:CGSizeMake(self.frame.size.width,60)];
bar.anchorPoint = CGPointMake(0, 0);
bar.position = CGPointMake(0, 50);
float space = (self.size.width - 45*6) / 7;
SKSpriteNode* letterBox = [SKSpriteNode spriteNodeWithImageNamed:@"letter_box_def"];
letterBox.anchorPoint = CGPointMake(0.5, 0.5);
letterBox.position = CGPointMake((space+((space + 45)*2)+22.5), 30);
[bar addChild:letterBox];
self.gl2 = [SKLabelNode labelNodeWithFontNamed:@"Arial"];
self.gl2.fontColor = [SKColor blackColor];
self.gl2.verticalAlignmentMode = SKLabelVerticalAlignmentModeCenter;
self.gl2.fontSize = 30;
self.gl2.text = @"";
NSLog(@"%@", self.gl2);
[letterBox addChild:self.gl2];
[self addChild:bar];
self.gl2.text = @"D";
}
予想どおり、実行時にノードに「D」が表示されます。私のタッチ方法は次のとおりです。
-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event{
NSLog(@"Called touchesBegan");
NSLog(@"Node : %@", self.gl2);
NSLog(@"Text : %@", self.gl2.text);
self.gl2.text = @"k";
NSLog(@"Node : %@", self.gl2);
NSLog(@"Text : %@", self.gl2.text);
}
これで、タッチするとラベルが画面から消えます。ログには次のように表示されます。

私が試したことは、levelSelected メソッドから呼び出される別のメソッドを使用することです。
-(void)levelSelected{
SKSpriteNode* bar = [SKSpriteNode spriteNodeWithColor:[UIColor colorWithHue:0.566f saturation:0.787f brightness:0.792f alpha:1] size:CGSizeMake(self.frame.size.width,60)];
bar.anchorPoint = CGPointMake(0, 0);
bar.position = CGPointMake(0, 50);
float space = (self.size.width - 45*6) / 7;
SKSpriteNode* letterBox = [SKSpriteNode spriteNodeWithImageNamed:@"letter_box_def"];
letterBox.anchorPoint = CGPointMake(0.5, 0.5);
letterBox.position = CGPointMake((space+((space + 45)*2)+22.5), 30);
[bar addChild:letterBox];
self.gl2 = [SKLabelNode labelNodeWithFontNamed:@"Arial"];
self.gl2.fontColor = [SKColor blackColor];
self.gl2.verticalAlignmentMode = SKLabelVerticalAlignmentModeCenter;
self.gl2.fontSize = 30;
self.gl2.text = @"";
NSLog(@"%@", self.gl2);
[letterBox addChild:self.gl2];
[self addChild:bar];
self.gl2.text = @"D";
[self touchedSomething];
}
-(void)touchedSomething {
NSLog(@"Called touchedSomething");
NSLog(@"Node : %@", self.gl2);
NSLog(@"Text : %@", self.gl2.text);
self.gl2.text = @"k";
NSLog(@"Node : %@", self.gl2);
NSLog(@"Text : %@", self.gl2.text);
}
これは完全に機能し、D は k に置き換えられ、log が生成されます。

2014-08-14 06:20:09.935 Guess[3132:608100] Node : <SKLabelNode> name:'(null)' text:'D' fontName:'Arial' position:{0, 0}
2014-08-14 06:20:09.935 Guess[3132:608100] Text : D

しかし、levelSelected から [self touchedSomething] 呼び出しを削除して touchesBegan に追加すると、機能せず、ラベルが再び画面から消えます。
-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event{
NSLog(@"Called touchesBegan");
[self touchedSomething];
}
-(void)touchedSomething {
NSLog(@"Called touchedSomething");
NSLog(@"Node : %@", self.gl2);
NSLog(@"Text : %@", self.gl2.text);
self.gl2.text = @"k";
NSLog(@"Node : %@", self.gl2);
NSLog(@"Text : %@", self.gl2.text);
}
