あるシーンから別のシーンにテキストフィールドを更新する

Question

あるシーンから別のシーンにデータ（textFieldテキスト）を配置する際に問題があります。 このメールでソースコードを添付しています。 私のコードで何か問題があれば助けてください。

NSString *result; 

@implementation MYSCENE 
-(id) init 
{ 
     [super init]; 

     id layer = [ColorLayer layerWithColor: 0x2266FFff]; 
     [self add:layer z:0]; 
     [MenuItemFont setFontSize:15]; 
     [MenuItemFont setFontName:@"Helvetica"]; 
     MenuItem *backMenu = [MenuItemFont itemFromString:@"Back" target:self selector:@selector(menuBack:)] 
; 
     Menu *menu = [Menu menuWithItems:backMenu,nil]; 

     [menu alignItemsVertically]; 
     [self add:menu]; 

    /*Text field creation*/ 
    myTextField = [[UITextField alloc]initWithFrame:CGRectMake(60, 165, 100, 10)]; 
    myTextField.placeholder=@"<Enter text>"; 
    [myTextField setDelegate:self]; 
    [window addSubview:myTextField]; 


    return self; 
} 

-(void)menuBack:(id)sender{ 
    NSLog(@"Back"); 
    TestScene *ts = [TestScene node]; 
    [[Director sharedDirector]replaceScene:ts]; 
} 

-(BOOL)textFieldShouldReturn:(UITextField *)textField { 
    [textField resignFirstResponder]; 
    return YES; 
} 

-(void)textFieldDidEndEditing:(UITextField *)textField{ 
    if(textField==myTextField){ 
     [myTextField endEditing:YES]; 

     result = myTextField.text; 
     [label setString:result]; 
     [myTextField removeFromSuperview]; 
    } 
} 

-(void) dealloc 
{ 
    [super dealloc]; 
} 
@end 

@implementation MenuLayer 

-(id)init { 
    self = [super init]; 



    return self; 
}

    Scene *scene = [Scene node]; 
    [scene add: [MYSCENE node]]; 

    [window makeKeyAndVisible]; 

    [[Director sharedDirector] runWithScene: scene];

ない完全に確認してください、私は

label = [Label labelWithString:@"result" fontName:@"Helvetica" fontSize:20.0]; 

label = [Label labelWithString:result fontName:@"Helvetica" fontSize:20.0];
