ipad中图片的动态显示。

view_base project

2个image view 1个page Control

代码：

- (void) pageTurning: (UIPageControl *) pageController
{
    //---get the page number you can turning to---
    NSInteger nextPage = [pageController currentPage];
    switch (nextPage) {
        case 0:
            [tempImageView setImage:[UIImage imageNamed:@"iMac_old.jpeg"]];
            break;
        case 1:
            [tempImageView setImage:[UIImage imageNamed:@"iMac.jpeg"]];
            break;
        case 2:
            [tempImageView setImage:[UIImage imageNamed:@"Mac8100.jpeg"]];
            break;
        case 3:
            [tempImageView setImage:[UIImage imageNamed:@"MacPlus.jpeg"]];
            break;
        case 4:
            [tempImageView setImage:[UIImage imageNamed:@"MacSE.jpeg"]];
            break;
        default:
            break;
    }
	
    //---switch the two imageview views---
    if (tempImageView.tag==0) { //---imageView1---
        tempImageView = imageView2;
        bgImageView = imageView1;
    }
    else {    //---imageView2---
        tempImageView = imageView1;
        bgImageView = imageView2;
    }
	
    //---animate the two views flipping---
    [UIView beginAnimations:@"flipping view" context:nil];
    [UIView setAnimationDuration:0.5];
    [UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];
    [UIView setAnimationTransition: UIViewAnimationTransitionFlipFromLeft
						   forView:tempImageView cache:YES];
    [tempImageView setHidden:YES];
    [UIView commitAnimations];
	
    [UIView beginAnimations:@"flipping view" context:nil];
    [UIView setAnimationDuration:0.5];
    [UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];
    [UIView setAnimationTransition: UIViewAnimationTransitionFlipFromRight
						   forView:bgImageView cache:YES];
    [bgImageView setHidden:NO];
    [UIView commitAnimations];
	
}

// Implement viewDidLoad to do additional setup after loading the view, typically from a nib.
- (void)viewDidLoad {
	
	//---initialize the first imageview to display an image---
    [imageView1 setImage:[UIImage imageNamed:@"iMac_old.jpeg"]];
    tempImageView = imageView2;
	
    //---make the first imageview visible and hide the second---
    [imageView1 setHidden:NO];
    [imageView2 setHidden:YES];
	
    //---add the event handler for the page control---
    [pageControl addTarget:self action:@selector(pageTurning:)
		  forControlEvents:UIControlEventValueChanged];
	
	[super viewDidLoad];
