在標準Flipside視圖內創建一個導航視圖？

Question

有誰知道如何在標準Flipside視圖內創建一個導航視圖來讀取和更新設置？如果是這樣，你可以發佈一些代碼來做到這一點。

Answer 1

您可以使flipside視圖成爲UINavigationController的一個子類。

或者，如果您只需要導航欄，而無需推送/彈出新的視圖控制器，並且從NIB加載翻轉視圖，則只需在NIB文件中添加一個導航欄即可。

Answer 2

您的應用程序委託頭文件（MyAppDelegate.h）：

@interface MyAppDelegate : NSObject <UIApplicationDelegate> { 

    IBOutlet UIWindow *window; 
    // We're assuming the root view for the main view is connected to this outlet of the app delegate 
    // It'll probably have a different class than UIViewController in your app 
    IBOutlet UIViewController *mainViewController; 
    UINavigationController *settingsNavigationController; 
} 

// Other view controllers can do [(MyAppDelegate *)[UIApplication sharedApplication].delegate showSettings] to show the settings 
- (void)showSettings; 
- (void)hideSettings; 

@end 

您的應用程序委託.m文件（MyAppDelegate.m）：

- (void)showSettings 
{ 
    // Load the settings view controller the first time it's needed 
    // We're assuming you created the root view controller for the settings in a nib called SettingsRootViewController.xib. You might also just create the root view programmatically (maybe by subclassing UITableViewController) 
    if(settingsNavigationController == nil) 
    { 
     SettingsRootViewController *settingsRootViewController = [[[SettingsRootViewController alloc] initWithNibName:@"SettingsRootViewController" bundle:nil] autorelease]; 
     settingsNavigationController = [[UINavigationController alloc] initWithRootViewController:settingsRootViewController]; 
     settingsNavigationController.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal 
    } 

    [rootViewController presentModalViewController:settingsNavigationController animated:YES]; 
} 

- (void)hideSettings 
{ 
    [settingsNavigationController dismissModalViewController:YES]; 
}
