//开发步骤
//1，搭建ui界面，建立scrollview
//2，增加分页功能
//3，添加分页控件
-(void)loadView{
//1，实例化视图view
self.view = [[UIView alloc]initWithFrame:[UIScreen
mainScreen].applicationFrame];
//2，创建滚动视图
UIScrollView *scroll = [[UIScrollView
alloc]initWithFrame:self.view.bounds];
//3，将scroll加载到当前视图
[self.view
addSubview:scroll];
//4，初始化数据
NSMutableArray *array = [[NSMutableArray
alloc]initWithCapacity:5];
for (NSInteger i = 0; i < 5; i++)
{
//创建图片的文件名
NSString
*imageName = [NSString stringWithFormat:@"%d.jpg",i+1];
//建立图像视图
UIImage
*images = [UIImage imageNamed:imageName];
UIImageView
*imageView = [[UIImageView alloc]initWithImage:images];
//将视图添加到数组
[array
addObject:imageView];

width = scroll.bounds.size.width;
//将建立好的数组添加到scrollView
[array
enumerateObjectsUsingBlock:^(id obj, NSUInteger idx, BOOL *stop)
{
//1，从数组中取出imageView
UIImageView *imageView = obj;
//2,设置图像视图的frame
[imageView setFrame:CGRectMake(width * idx, 0, width,
scroll.bounds.size.height)];
//3，将图像视图添加到scroller
[scroll addSubview:imageView];
}];
//设置滚动视图属性
//1，设置滚动区域
[scroll
setContentSize:CGSizeMake(scroll.bounds.size.width * 5,
scroll.bounds.size.width)];
//2,允许分页
[scroll
setPagingEnabled:YES];
//3，关闭弹簧效果
[scroll
setBounces:NO];
//4，关闭水平滚动条
[scroll
setShowsHorizontalScrollIndicator:NO];
//设置滚动视图代理
[scroll
setDelegate:self];
//添加分页控件
UIPageControl *pageControl = [[UIPageControl alloc]init];
//根据指定的页数，返回分页控件的大小
CGSize size
= [pageControl sizeForNumberOfPages:5];
[pageControl
setFrame:CGRectMake(0, 0, size.width, size.height)];
//设置分页控件的位子
[pageControl
setCenter:CGPointMake(width / 2 , 400)];
//设置分页控件的页数
[pageControl
setNumberOfPages:5];
[pageControl
setCurrentPage:0];
//设置分页控件的颜色
[pageControl
setCurrentPageIndicatorTintColor:[UIColor redColor]];
[pageControl setPageIndicatorTintColor:[UIColor blackColor]];
//添加到视图
[self.view
addSubview:pageControl];
self.pageController =pageControl;
self.scrollder = scroll;
//添加分页空间的监听方法
[pageControl
addTarget:self action:@selector(pageChange:)
forControlEvents:UIControlEventValueChanged];
