在基于分割的应用程序中手动更改视图

Question

我想让我的应用程序在用户单击“提交”按钮后切换视图。

这是我到目前为止有：

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类中声明（我从苹果示例代码开始）。

代码生成的很好，但是当我调用方法时，什么都不会发生。

我刚刚也要学习最近如何做到这一点。我想要在屏幕上显示一个“关于”按钮，当用户点击按钮时会翻到另一个视图中，然后在点击“完成”按钮时翻转回原始视图。

我觉得你太过复杂了。这是我必须展示关于视图的代码。

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

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

显然，别忘了将其导入你的头：#import <AboutViewController.h>

而且我的代码带回原来的视图（又名隐藏有关视图）是：[self.parentViewController dismissModalViewControllerAnimated:YES];
