TYPagerController v2.0

TYPagerController 简单,强大,高度定制,页面控制器,水平滚动内容和标题栏,包含多种barStyle。
TYPagerController v2.0 重构优化代码,分离出TYPagerViewLayout布局类,添加更多功能,更加强大。
如果还想使用以前的版本可以查看分支v1.0.6 和 pod ‘TYPagerController’, ‘~> 1.0.6’

  • TYPagerViewLayout 水平滚动页面的layout类,只需要initWithScrollView:即可实现水平滚动页面.
  • TYPagerView 包含TYPagerViewLayout的水平滚动页面View
  • TYPagerController 包含TYPagerViewLayout的水平滚动页面Controller。
  • TYTabPagerBar Pager的标题 tabBar
  • TYTabPagerView 包含TabBar的TYPagerView
  • TYTabPagerController 包含TabBar的TYPagerController

Class

  • TYPagerViewLayout
    
    @interface TYPagerViewLayout<__covariant ItemType> : NSObject

@property (nonatomic, weak, nullable) id dataSource;
@property (nonatomic, weak, nullable) id delegate;

// strong,will control the delegate,don’t set delegate on other place.
@property (nonatomic, strong, readonly) UIScrollView *scrollView;
// if viewcontroller’s automaticallyAdjustsScrollViewInsets YES ,will cause frame problems, you can set YES, default YES
@property (nonatomic, assign) BOOL adjustScrollViewInset;

@property (nonatomic, assign, readonly) NSInteger countOfPagerItems;
@property (nonatomic, assign, readonly) NSInteger curIndex;// default -1

@property (nonatomic, strong, readonly) NSCache<NSNumber ,ItemType> memoryCache;; // will cache pagerView,you can set countLimit
@property (nonatomic, assign) BOOL autoMemoryCache; // default YES

@property (nonatomic, assign) NSInteger prefetchItemCount;// preload left and right item’s count , default 0

@property (nonatomic, assign, readonly) NSRange prefetchRange;
@property (nonatomic, assign, readonly) NSRange visibleRange;

@property (nonatomic, strong, nullable, readonly) NSArray<NSNumber > visibleIndexs;
@property (nonatomic, strong, nullable, readonly) NSArray * visibleItems;

// default YES, if NO,will not call delegate transitionFromIndex:toIndex:progress:,but will call transitionFromIndex:toIndex:
@property (nonatomic, assign) BOOL progressAnimateEnabel;

// default NO, when scroll visible range change will add item.If YES add item only when scroll animate end, suggest set prefetchItemCount 1 or more
@property (nonatomic, assign) BOOL addVisibleItemOnlyWhenScrollAnimatedEnd;

// default 0.5,when scroll progress percent will change index, only progressAnimateEnabel is NO or don’t implement delegate transitionFromIndex: toIndex: progress:

Usage Demo

  • TYTabPagerView
  • (void)addTabPagerView {
    TYTabPagerView *pagerView = [[TYTabPagerView alloc]init];
    pagerView.tabBar.layout.barStyle = TYPagerBarStyleCoverView;

    pagerView.dataSource = self;
    pagerView.delegate = self;
    [self.view addSubview:pagerView];
    _pagerView = pagerView;
    }
