iphone - coverflow 就像给定的图片

Question

我想制作 UIScrollView 或像这样的封面流 我尝试了一些像 icaraousal 等的封面流，但那些没有产生像这样的感觉所以如果有人知道这种类型的封面那么请给我建议.

和iCarousal创造了这种类型的 View ，可以看到侧面图像的位置和角度的差异

Answer 1

您可能正在寻找这个 awsome library这将完全按照您的要求进行

但是你必须在里面做一些编辑才能达到你想要的方式

它有大量的委托(delegate)，可以用来实现你正在寻找的东西

@protocol iCarouselDataSource <NSObject>

- (NSUInteger)numberOfItemsInCarousel:(iCarousel *)carousel;
- (UIView *)carousel:(iCarousel *)carousel viewForItemAtIndex:(NSUInteger)index reusingView:(UIView *)view;

@optional

- (NSUInteger)numberOfPlaceholdersInCarousel:(iCarousel *)carousel;
- (UIView *)carousel:(iCarousel *)carousel placeholderViewAtIndex:(NSUInteger)index reusingView:(UIView *)view;
- (NSUInteger)numberOfVisibleItemsInCarousel:(iCarousel *)carousel;

//deprecated, use carousel:viewForItemAtIndex:reusingView: and carousel:placeholderViewAtIndex:reusingView: instead
- (UIView *)carousel:(iCarousel *)carousel viewForItemAtIndex:(NSUInteger)index __deprecated;
- (UIView *)carousel:(iCarousel *)carousel placeholderViewAtIndex:(NSUInteger)index __deprecated;

@end


@protocol iCarouselDelegate <NSObject>
@optional

- (void)carouselWillBeginScrollingAnimation:(iCarousel *)carousel;
- (void)carouselDidEndScrollingAnimation:(iCarousel *)carousel;
- (void)carouselDidScroll:(iCarousel *)carousel;
- (void)carouselCurrentItemIndexUpdated:(iCarousel *)carousel;
- (void)carouselWillBeginDragging:(iCarousel *)carousel;
- (void)carouselDidEndDragging:(iCarousel *)carousel willDecelerate:(BOOL)decelerate;
- (void)carouselWillBeginDecelerating:(iCarousel *)carousel;
- (void)carouselDidEndDecelerating:(iCarousel *)carousel;
- (CGFloat)carouselItemWidth:(iCarousel *)carousel;
- (CGFloat)carouselOffsetMultiplier:(iCarousel *)carousel;
- (BOOL)carouselShouldWrap:(iCarousel *)carousel;
- (CGFloat)carousel:(iCarousel *)carousel itemAlphaForOffset:(CGFloat)offset;
- (CATransform3D)carousel:(iCarousel *)carousel itemTransformForOffset:(CGFloat)offset baseTransform:(CATransform3D)transform;
- (CGFloat)carousel:(iCarousel *)carousel valueForTransformOption:(iCarouselTranformOption)option withDefault:(CGFloat)value;

//deprecated, use transformForItemAtIndex:withOffset:baseTransform: instead
- (CATransform3D)carousel:(iCarousel *)carousel transformForItemView:(UIView *)view withOffset:(CGFloat)offset __deprecated;


- (BOOL)carousel:(iCarousel *)carousel shouldSelectItemAtIndex:(NSInteger)index;
- (void)carousel:(iCarousel *)carousel didSelectItemAtIndex:(NSInteger)index;
