本文主要介绍scrollView的使用，使用scrollView来做一个手机相册。

内容不多，直接上代码

#import "RootViewController.h"#define Kwidth _scrollView.frame.size.width #define kHight _scrollView.frame.size.height@interface RootViewController ()@property(nonatomic,retain)UIScrollView * scrollView;@end@implementation RootViewController- (void)viewDidLoad {    [super viewDidLoad];    self.scrollView = [[UIScrollView alloc]initWithFrame:CGRectMake(30, 100, 320, 480)];    self.view.backgroundColor = [UIColor whiteColor];    _scrollView.backgroundColor = [UIColor greenColor];    [self.view addSubview:_scrollView];    _scrollView.contentSize = CGSizeMake(19*Kwidth,kHight);    for (int i = 0; i<19; i++) {        NSString *imageName = [NSString stringWithFormat:@"image%d.jpg",i+1];        UIImage *image = [UIImage imageNamed:imageName];        UIImageView *imageView = [[UIImageView alloc]initWithFrame:CGRectMake(i*Kwidth, 0, Kwidth, kHight)];        imageView.image = image;        [_scrollView addSubview:imageView];        [imageView release];    }    _scrollView.pagingEnabled = YES;    [_scrollView release];    // Do any additional setup after loading the view.}
