iphone - 像给定的图片一样的coverflow


                                            <p><p>我想制作 <code>UIScrollView</code> 或这样的封面流.</p>

<p>和 iCarousal 创建这种类型的 View ，看看侧面图像的位置和角度的差异</p>

<p> <img src="/image/FUXm3.png" alt="enter image description here"/> </p></p>

                                            <p><p>您可能正在寻找 <a href="https://github.com/nicklockwood/iCarousel" rel="noreferrer noopener nofollow">awsome library</a>这将完全符合您的要求</p>

<p>但是你必须在里面做一些编辑才能达到你想要的方式</p>

<p>它有大量的委托(delegate)，可以用来实现你正在寻找的东西</p>

<pre><code>@protocol iCarouselDataSource &lt;NSObject&gt;

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

//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 &lt;NSObject&gt;
