滾動查看網格TabelView

-3

我爲全新的iPhone開發，這是我有一個關於如何使用下面的代碼滾動查看網格TabelView

#import <UIKit/UIKit.h> 

@class ScrollViewViewController; 

@interface ScrollViewAppDelegate : NSObject <UIApplicationDelegate> { 
    UIWindow *window; 
    ScrollViewViewController *viewController; 
} 

@property (nonatomic, retain) IBOutlet UIWindow *window; 
@property (nonatomic, retain) IBOutlet ScrollViewViewController *viewController; 

@end

在上面的代碼中，如果我爲UIIMage設置滾動，那麼它的工作原理，但如果我爲RootViewController設置滾動視圖，那麼它不工作。

請幫助在此先感謝

首先格式化您的問題，並且不要將您的所有代碼放在這裏。StackOverflow用於幫助您堅持不要代碼審查的地方。只輸入相關的代碼，並確切地告訴我們你想要達到的目標。 – lukya 2010-07-23 06:24:37

@lukya：好的，這次我爲他做了。 @aman：請在下次格式化您的代碼 – vodkhang 2010-07-23 06:26:38

天啊。這麼多的代碼......沒有人會讀所有的。請在你的問題中更簡潔。 – Nubsis 2010-07-23 06:52:25

我沒看過你的代碼，請重新格式化，以便其他人可以輕鬆地閱讀它。

你是指在UITableView中的UIScrollView是什麼意思？在細胞內部？我仍然不明白。僅供參考UITableView繼承自UIScrollView ...

您真正想要實現哪些功能？我會推薦閱讀一些Apple給出的樣本。關於UIKit有很多很好的例子。
