property'scrollView'需要定义方法'-scrollView' - 使用@synthesize，@dynamic或提供方法实现？

Question

这是什么意思？

属性'scrollView'需要方法'-scrollView'来定义 - 使用@synthesize，@dynamic还是提供一个方法实现？

它告诉我，在同一行@end

#import <UIKit/UIKit.h> 

@class ViewScrollViewController; 

@interface ViewScrollAppDelegate : NSObject <UIApplicationDelegate> { 
    UIWindow *window; 
    ViewScrollViewController *viewController; 
    UIScrollView *scrollView; 
    UITextView *textView; 
} 

@property (nonatomic, retain) IBOutlet UIWindow *window; 
@property (nonatomic, retain) IBOutlet ViewScrollViewController *viewController; 
@property (nonatomic, retain) IBOutlet UIScrollView *scrollView; 
@property (nonatomic, retain) IBOutlet UITextView *textView; 

@end

你合成的财产？

这样的..

//your .h file... 
@interface myViewController:UIViewController{ 
    ScrollView *scrollView; 
} 
@property(nonatomic,retain)ScrollView *scrollView; 
@end 


//your .m file 

@implementation myViewController 
@synthesize scrollView;  //are you doing this? 

... 
... 
... 
@end 

编辑：基于编辑的问题，提问者的代码片断..

在您.m文件..

@implementation ViewScrollAppDelegate 

@synthesize scrollView,window,viewController,textView; 

//Now your implementation.. 
... 
.. 
@end
