+
+## API
+
+*  DataSource and Delegate 
+```objc
+
+@protocol TYCyclePagerViewDataSource <NSObject>
+
+- (NSInteger)numberOfItemsInPagerView:(TYCyclePagerView *)pageView;
+
+- (__kindof UICollectionViewCell *)pagerView:(TYCyclePagerView *)pagerView cellForItemAtIndex:(NSInteger)index;
+
+/**
+ return pagerView layout,and cache layout
+ */
+- (TYCyclePagerViewLayout *)layoutForPagerView:(TYCyclePagerView *)pageView;
+
+@protocol TYCyclePagerViewDelegate <NSObject>
+
+@optional
+
+/**
+ pagerView did scroll to new index page
+ */
+- (void)pagerView:(TYCyclePagerView *)pageView didScrollFromIndex:(NSInteger)fromIndex toIndex:(NSInteger)toIndex;
+
+/**
+ pagerView did selected item cell
+ */
+- (void)pagerView:(TYCyclePagerView *)pageView didSelectedItemCell:(__kindof UICollectionViewCell *)cell atIndex:(NSInteger)index;
+
+// More API see project
+```
+
+* Class
+
+```objc
+
+@interface TYCyclePagerView : UIView
+
+// will be automatically resized to track the size of the pagerView
+@property (nonatomic, strong, nullable) UIView *backgroundView; 
+
+@property (nonatomic, weak, nullable) id<TYCyclePagerViewDataSource> dataSource;
+@property (nonatomic, weak, nullable) id<TYCyclePagerViewDelegate> delegate;
+
+// pager view layout is important
+@property (nonatomic, strong, readonly) TYCyclePagerViewLayout *layout;
+
+/**
+ is infinite cycle pageview
+ */
+@property (nonatomic, assign) BOOL isInfiniteLoop;
+
+/**
+ pagerView automatic scroll time interval, default 0,disable automatic
+ */
+@property (nonatomic, assign) CGFloat autoScrollInterval;
+
+
+@interface TYCyclePagerViewLayout : NSObject
+
+@property (nonatomic, assign) CGSize itemSize;
+@property (nonatomic, assign) CGFloat itemSpacing;
+@property (nonatomic, assign) UIEdgeInsets sectionInset;
+
+@property (nonatomic, assign) TYCyclePagerTransformLayoutType layoutType;
+
+@property (nonatomic, assign) CGFloat minimumScale; // sacle default 0.8
+@property (nonatomic, assign) CGFloat minimumAlpha; // alpha default 1.0
+@property (nonatomic, assign) CGFloat maximumAngle; // angle is % default 0.2
+
+
+@interface TYPageControl : UIControl
+
+@property (nonatomic, assign) NSInteger numberOfPages;          // default is 0
+@property (nonatomic, assign) NSInteger currentPage;            // default is 0. value pinned to 0..numberOfPages-1
+
+// indicatorTint color
+@property (nullable, nonatomic,strong) UIColor *pageIndicatorTintColor;
+@property (nullable, nonatomic,strong) UIColor *currentPageIndicatorTintColor;
+
+// indicator image
+@property (nullable, nonatomic,strong) UIImage *pageIndicatorImage;
+@property (nullable, nonatomic,strong) UIImage *currentPageIndicatorImage;
+```
+
+## Usage
+
+```objc
+
+- (void)addPagerView {
+    TYCyclePagerView *pagerView = [[TYCyclePagerView alloc]init];
+    pagerView.layer.borderWidth = 1;
+    pagerView.isInfiniteLoop = YES;
+    pagerView.autoScrollInterval = 3.0;
+    pagerView.dataSource = self;
+    pagerView.delegate = self;
+    // registerClass or registerNib
+    [pagerView registerClass:[TYCyclePagerViewCell class] forCellWithReuseIdentifier:@"cellId"];
+    [self.view addSubview:pagerView];
+    _pagerView = pagerView;
+}
+
+- (void)addPageControl {
+    TYPageControl *pageControl = [[TYPageControl alloc]init];
+    //pageControl.numberOfPages = _datas.count;
+    pageControl.currentPageIndicatorSize = CGSizeMake(8, 8);
+//    pageControl.pageIndicatorImage = [UIImage imageNamed:@"Dot"];
+//    pageControl.currentPageIndicatorImage = [UIImage imageNamed:@"DotSelected"];
+//    [pageControl addTarget:self action:@selector(pageControlValueChangeAction:) forControlEvents:UIControlEventValueChanged];
+    [_pagerView addSubview:pageControl];
+    _pageControl = pageControl;
+}
+- (void)loadData {
+    // load data to _datas
+    _pageControl.numberOfPages = _datas.count;
+    [_pagerView reloadData];
+}
+
+```
