第三天

代码摘录一: - (void)viewDidLoad { MainViewController *viewController = [[MainViewController alloc] initWithNibName:@"MainView" bundle:nil]; self.mainViewController = viewController; [viewController release]; [self.view insertSubview: mainViewController.view belowSubview: infoButton]; } - (void)loadFlipsideViewController { FlipsideViewController *viewController = [[FlipsideViewController alloc] initWithNibName:@"FlipsideView" bundle:nil]; self.flipsideViewController = viewController; [viewController release]; // Set up the navigation bar UINavigationBar *aNavigationBar = [[UINavigationBar alloc] initWithFrame:CGRectMake(0.0, 0.0, 320.0, 44.0)]; aNavigationBar.barStyle = UIBarStyleBlackOpaque; self.flipsideNavigationBar = aNavigationBar; [aNavigationBar release]; UIBarButtonItem *buttonItem = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemDone target:self action:@selector(toggleView)]; UINavigationItem *navigationItem = [[UINavigationItem alloc] initWithTitle:@"openURL"]; navigationItem.rightBarButtonItem = buttonItem; //显示Item. [flipsideNavigationBar pushNavigationItem: navigationItem animated:NO]; [navigationItem release]; [buttonItem release]; } - (IBAction)toggleView { /* This method is called when the info or Done button is pressed. It flips the displayed view from the main view to the flipside view and vice-versa. */ if (flipsideViewController == nil) { [self loadFlipsideViewController]; } UIView *mainView = mainViewController.view; UIView *flipsideView = flipsideViewController.view; [UIView beginAnimations:nil context:NULL]; [UIView setAnimationDuration:1]; [UIView setAnimationTransition:([mainView superview] ? UIViewAnimationTransitionFlipFromRight : UIViewAnimationTransitionFlipFromLeft) forView:self.view cache:YES]; if ([mainView superview] != nil) { [flipsideViewController viewWillAppear:YES]; [mainViewController viewWillDisappear:YES]; [mainView removeFromSuperview]; [infoButton removeFromSuperview]; [self.view addSubview:flipsideView]; [self.view insertSubview:flipsideNavigationBar aboveSubview:flipsideView]; [mainViewController viewDidDisappear:YES]; [flipsideViewController viewDidAppear:YES]; } else { [mainViewController viewWillAppear:YES]; [flipsideViewController viewWillDisappear:YES]; [flipsideView removeFromSuperview]; [flipsideNavigationBar removeFromSuperview]; [self.view addSubview:mainView]; [self.view insertSubview:infoButton aboveSubview:mainViewController.view]; [flipsideViewController viewDidDisappear:YES]; [mainViewController viewDidAppear:YES]; } [UIView commitAnimations]; }

设置背影颜色: self.view.backgroundColor = [UIColor viewFlipsideBackgroundColor];
