在基於分割的應用程序中手動更改視圖

Question

我想讓我的應用程序在用戶單擊「提交」按鈕後切換視圖。

這是我到目前爲止有：

viewA.h

@property (nonatomic, retain) RootViewController *root; 

viewA.m

-(void)switchToLogView{ 

NSLog(@"switch to log view"); 

UIViewController <SubstitutableDetailViewController> *detailViewController = nil; 
LogDetailViewController *newDetailViewController = [[LogDetailViewController alloc] initWithNibName:@"LogDetailViewController" bundle:nil]; 
detailViewController = newDetailViewController; 

// Update the split view controller's view controllers array. 
NSArray *viewControllers = [[NSArray alloc] initWithObjects:self.navigationController, detailViewController, nil]; 
root.splitViewController.viewControllers = viewControllers; 

// Dismiss the popover if it's present. 
if (root.popoverController != nil) { 
    [root.popoverController dismissPopoverAnimated:YES]; 
} 

// Configure the new view controller's popover button (after the view has been displayed and its toolbar/navigation bar has been created). 
if (root.rootPopoverButtonItem != nil) { 
    [detailViewController showRootPopoverButtonItem:self.root.rootPopoverButtonItem]; 
} 

[detailViewController release]; 

} 

的splitViewController，popoverController和rootPopoverButtonItem都在我的RootViewController類中聲明（我從蘋果示例代碼開始）。

代碼生成的很好，但是當我調用方法時，什麼都不會發生。

我剛剛也要學習最近如何做到這一點。我想要在屏幕上顯示一個「關於」按鈕，當用戶點擊按鈕時會翻到另一個視圖中，然後在點擊「完成」按鈕時翻轉回原始視圖。

我覺得你太過複雜了。這是我必須展示關於視圖的代碼。

AboutViewController *aboutViewController = [[AboutViewController alloc] initWithNibName:@"AboutViewController" bundle:nil]; 

aboutViewController.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal; 
[self presentModalViewController:aboutViewController animated:YES]; //Show it! 

顯然，別忘了將其導入你的頭：#import <AboutViewController.h>

而且我的代碼帶回原來的視圖（又名隱藏有關視圖）是：[self.parentViewController dismissModalViewControllerAnimated:YES];
