这个效果的实现是用UIScrollView。核心代码如下：

[cpp]view plaincopy

1. NSArray *myImages = [NSArray arrayWithObjects:[UIImage imageNamed:@"1.jpg"],nil];  
2. UIScrollView *scrollView = [[UIScrollView alloc] initWithFrame:CGRectMake(0, 60, 320, imageSizeHeight)];  
3.     for (int i = 0; i <[myImages count]; i++) {  
4.         UIImageView *imageView = [[UIImageView alloc]initWithImage:[myImages objectAtIndex:i]];  
5.         imageView.frame = CGRectMake(imageSizeWidth*i, 0, imageSizeWidth, imageSizeHeight);  
6.         imageView.contentMode = UIViewContentModeScaleAspectFit;  
7.         [scrollView addSubview:imageView];  
8.     }  
9.     scrollView.contentSize = CGSizeMake(imageSizeWidth*[myImages count],imageSizeHeight);  
10. //  scrollView.pagingEnabled = YES;  
11.     scrollView.showsVerticalScrollIndicator = NO;  
12.     scrollView.showsHorizontalScrollIndicator = NO;  
13.     scrollView.userInteractionEnabled = YES;
