易用的半透明浮层操作引导，只需给出需要高亮的view或rect区域，支持多个高亮区域。
Translucent guide window control.Just needs views or rects to highlight.
// show
JHGuideController *guideController = [JHGuideController new];
guideController.snapshotViewUpdates = YES;
[guideController showWithViewsToSnapshot:@[view1, view2, view3]];
// callback
[guideController setTapBlock:^(UIView *snapshotView, CGRect rect) {
// do something
}];
详见Demo工程
// 通过复制view实现效果
- (void)showWithViewToSnapshot:(UIView *)view;
- (void)showWithViewsToSnapshot:(NSArray<__kindof UIView *> *)array;
// 通过镂空半透明浮层实现效果
- (void)showWithRectToHollow:(CGRect)rect;
- (void)showWithRectsToHollow:(NSArray <__kindof NSValue *>*)array;
