我在 iOS4 上的应用程序（ipad）有问题。键盘不起作用，在第一个视图（登录视图）之后不会显示在我的 web 视图上。

应用程序：

AppDelegate.h 
    @class RootViewController;
    @interface StandardFacileAppDelegate : NSObject <UIApplicationDelegate> {
        UIWindow *window;
        RootViewController *rootViewController;
    }
    @property (nonatomic, retain) IBOutlet UIWindow *window;
    @property (nonatomic, retain) IBOutlet RootViewController *rootViewController;

AppDelegate.m
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{

    rootViewController = [[RootViewController alloc] init];                
     window.rootViewController = rootViewController;
    //[window addSubview:rootViewController.view];
    [window makeKeyAndVisible];

    return YES;
}

根视图控制器：

- (void)viewDidLoad {
[super viewDidLoad];
[self loadViewController];
[self.view addSubview:viewController.view];
}
- (void)loadViewController {
ViewController *viewControllertemp = [[ViewController alloc]initWithNibName:@"ViewController" bundle:nil];
self.viewController = viewControllertemp;
[viewControllertemp release];}

viewController 是我请求后的登录视图，我调用了更改视图的方法（我的 webview）：

- (void)changeViewToIpadTheWebView:(UIViewController *)fromView{

UIViewController *currentView = (UIViewController*)fromView;
NSLog(@"currentView =>%@",currentView);
if(!ipadTheWebView)
    [self loadipadTheWebView];
[currentView.view removeFromSuperview];
for (UIView *view in [self.view subviews]) {
    [view removeFromSuperview];
}
[self.view addSubview:ipadTheWebView.view];

NSURL *url = [NSURL URLWithString:@"http://www.google.com/"];

NSURLRequest *requestURL = [NSURLRequest requestWithURL:url];
[ipadTheWebView.webView loadRequest:requestURL];

我的 webview 没问题，但如果我想在 google 中搜索单词，当文本字段获得焦点时，键盘不会显示（视图滚动）。

有什么问题，这段代码适用于 iOS5 而不是 ios4？

谢谢你的帮助 ;）

编辑：谢谢马修，

RootViewController.h

#import <UIKit/UIKit.h>

@class ViewController;
@class IpadTheWebView;


@interface RootViewController : UIViewController {
    ViewController *viewController;
    IpadTheWebView *ipadTheWebView;

}
@property (nonatomic,retain) ViewController *viewController;
- (void)loadViewController;
- (void)changeViewToViewController:(UIViewController *)fromView;

@property (nonatomic,retain) IpadTheWebView *ipadTheWebView;
- (void)loadipadTheWebView;
- (void)changeViewToIpadTheWebView:(UIViewController *)fromView;

- (void)keyboardWillShow:(NSNotification *)notification;
- (void)keyboardWillHide:(NSNotification *)note;
