WHCycleScrollView

• 輪播循環滾動，可自定義循環時間，方向；
• 數據源支持URL和本地資源圖片同時混用；
• 通過block和協議回調點擊和長按事件；
• 集成UIPageControl,且支持左中右三個位置；
</ul>

一行代碼實現自動輪播和pageControl

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




屬性說明:

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

dataSource支持URL和本地圖片名混用，URL元素以NSURL形式，本地圖片以NSString形式放入數組中。在數據源有變化時，直接設置此屬性即可，PageControl會跟著變化。

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

placeholderImage是加載URL資源時的占位圖

---

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

needPageControl默認為NO，如果需要可設置為YES，即可集成

@property (nonatomic, assign) WHPageControlLocation pageControlType;

pageControlType是設置pageControl位置的屬性，有三個枚舉值，默認是在中間

typedef NS_ENUM(NSInteger, WHPageControlLocation ){
    WHPageControlLocationLeft,
    WHPageControlLocationCenter,
    WHPageControlLocationRight,
};

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

這兩個屬性用于設置pageContol的當前page顏色和其它page顏色

---

@property (nonatomic, assign) BOOL needAutoCycle;

needAutoCycle默認為NO，如果需要輪播則設置為YES

@property (nonatomic, assign) NSTimeInterval autoCycleInterval;

autoCycleInterval用于設置輪播間隔，默認為5.0f

@property (nonatomic, assign) WHCycleDirection cycleDirection

cycleDirection用于設置輪播滾動方向,默認是向右

typedef NS_ENUM(NSInteger, WHCycleDirection){
    WHCycleDirectionRight,
    WHCycleDirectionLeft,
};

---

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

tapAction，單擊事件block回調

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

longPressAction,長按事件block回調

---

• 除了用block回調外，還可以通過WHCycleScrollViewDelegate協議來回調
• ps:URL加載采用SDWebImage
