WHCycleScrollView

• 轮播循环滚动，可自定义循环时间，方向；
• 数据源支持URL和本地资源图片同时混用；
• 通过block和协议回调点击和长按事件；
• 集成UIPageControl,且支持左中右三个位置；

一行代码实现自动轮播和pageControl

      WHCycleScrollView* cycleScrollView = [WHCycleScrollView cycleScrollViewWithFrame:self.view.bounds dataSource:urls pageControl:YES autoCycle:YES];

属性说明:

@property (nonnull, nonatomic, strong) NSArray * dataSource;

dataSource支持URL和本地图片名混用，URL元素以NSURL形式，本地图片以NSString形式放入数组中。在数据源有变化时，直接设置此属性即可，PageControl会跟着变化。

@property (nullable, nonatomic, strong) UIImage * placeholderImage;

placeholderImage是加载URL资源时的占位图

@property (nonatomic, assign) BOOL needPageControl; //default is NO

needPageControl默认为NO，如果需要可设置为YES，即可集成

@property (nonatomic, assign) WHPageControlLocation pageControlType;

pageControlType是设置pageControl位置的属性，有三个枚举值，默认是在中间    typedef NS_ENUM(NSInteger, WHPageControlLocation ){      WHPageControlLocationLeft,      WHPageControlLocationCenter,      WHPageControlLocationRight,  };

@property (nullable, nonatomic, strong) UIColor * pageIndicatorTintColor; @property (nullable, nonatomic, strong) UIColor *currentPageIndicatorTintColor;

这两个属性用于设置pageContol的当前page颜色和其它page颜色

@property (nonatomic, assign) BOOL needAutoCycle;

needAutoCycle默认为NO，如果需要轮播则设置为YES

@property (nonatomic, assign) NSTimeInterval autoCycleInterval;

autoCycleInterval用于设置轮播间隔，默认为5.0f

@property (nonatomic, assign) WHCycleDirection cycleDirection

cycleDirection用于设置轮播滚动方向,默认是向右    typedef NS_ENUM(NSInteger, WHCycleDirection){      WHCycleDirectionRight,      WHCycleDirectionLeft,  };

@property (nullable, nonatomic, copy) void (^tapAction)(NSInteger index);

tapAction，单击事件block回调

@property (nullable, nonatomic, copy) void (^longPressAction)(NSInteger index);

longPressAction,长按事件block回调

• 除了用block回调外，还可以通过WHCycleScrollViewDelegate协议来回调
• ps:URL加载采用SDWebImage
