推荐答案

In didload方法调用两个方法来创建滚动视图和缩略图按钮。以相同的顺序保存缩略图图像和壁纸图像数组。

In didload method call two methods to create scroll view and thumbnail button.Keep both thumbnail images and wallpaper images array in the same order.

-(void)createScrollView
{
scrollView = [[UIScrollView alloc] initWithFrame:CGRectMake(0, 0, 320, 440)];
scrollView.pagingEnabled = YES;
scrollView.showsHorizontalScrollIndicator = NO;
scrollView.showsVerticalScrollIndicator = NO;
scrollView.scrollsToTop = NO;
scrollView.delegate = self;
scrollView.contentSize = CGSizeMake(320 * (([imagesArray count]- 1) / 25 + 1), 440);

scrollView.backgroundColor=[UIColor blackColor];
[self.view addSubview:scrollView];

}

 -(void)createButton{
for (int i = 0; i < [imagesArray count]; i++) 
{

    thumbNailButton = [UIButton buttonWithType:UIButtonTypeCustom];
    thumbNailButton.frame = CGRectMake(6 + 62 * (i % 5) + 320 * (i / 25), 5+65 * ((i / 5) % 5), 56,56);

    img = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 56, 56)];
    [img setImage:[UIImage imageNamed:[imagesArray objectAtIndex:i]]];
    thumbNailButton.tag=i;
    [thumbNailButton addTarget:self action:@selector(imageClicked:) forControlEvents:UIControlEventTouchUpInside];   
    [thumbNailButton addSubview:img];
    [scrollView addSubview:thumbNailButton];

}

}

 -(void)imageClicked:(id)sender{
UIButton* button = (UIButton*)sender;
    AppDelegate *appDelegate=(AppDelegate *)[[UIApplication sharedApplication]delegate];
[appDelegate setimageClickedValue:button.tag];

LargeWallPaperviewController *largeWallPaperViewController=[[LargeWallPaperviewController alloc]initWithNibName:@"LargeWallPaperviewController" bundle:nil];
[self.navigationController pushViewController:largeWallPaperViewController animated:YES];
[largeWallPaperViewController release];
}

在didload方法的largewallpaperviewcontroller类中

In largewallpaperviewcontroller class in didload method

   [imagesArray addObjectsFromArray:[NSArray arrayWithObjects:@"wallf1.jpg",@"wallf2.jpg",@"wallf3.jpg",@"wallf4.jpg",@"wallf5.jpg",@"wallf6.jpg",@"wallf7.jpg",nil]];

scrollView = [[UIScrollView alloc] initWithFrame:CGRectMake(0, 0, 320, 440)];
scrollView.pagingEnabled = YES;
scrollView.showsHorizontalScrollIndicator = NO;
scrollView.showsVerticalScrollIndicator = NO;
scrollView.scrollsToTop = NO;
scrollView.delegate = self;
scrollView.contentSize = CGSizeMake(320 * ([imagesArray count] ), 440);
scrollView.backgroundColor = [UIColor blackColor];
[self.view addSubview:scrollView];

for (int i = 0; i < [imagesArray count]; i++) 
{

    wallPaperButton=[UIButton buttonWithType:UIButtonTypeCustom];
    wallPaperButton.tag=i;
    wallPaperButton.frame=CGRectMake((320*i),0, 320, 325);

    UIImageView *img =[ [UIImageView alloc]initWithFrame:CGRectMake(0,0, 320, 325)];

    img.image=[UIImage imageNamed:[imagesArray objectAtIndex:i]];
    img.contentMode=UIViewContentModeScaleAspectFit;            
    [wallPaperButton addSubview:img];
    [img release];


    [wallPaperButton addTarget:self action:@selector(imageSelected:) forControlEvents:UIControlEventTouchUpInside];     [scrollView addSubview:wallPaperButton];
}
appDelegate=(AppDelegate *)[[UIApplication sharedApplication]delegate];
int imageValue=[appDelegate getimageClickedValue];
[scrollView scrollRectToVisible:CGRectMake(320*imageValue, 0, 320 , 440) animated:NO];

我在largewallpaer视图中使用了一个按钮。如果你想删除它并直接添加到图像视图。这个代码对我有用，可以根据您的要求进行更改。它很容易理解。

i have used a button in the largewallpaer view.If you want you remove it and directly add it to image view.This code is working for me ,change it to your requirement.Its easy to understand.

一切都很好。
