ios - 在我的应用程序中开源 iCarousel

Question

我在我的 CoverFlow 应用中实现了 iCarousel。我找不到检测方法，现在显示的是哪个 View 。

有人知道吗？谢谢。

Answer 1

根据documentation ，您可以使用属性 currentItemIndex:

@property (nonatomic, readonly) NSInteger currentItemIndex;

The index of the currently centered item in the carousel (read only).

或者属性currentItemView:

@property (nonatomic, retain, readonly) UIView *currentItemView;

The currently centered item view in the carousel. The index of this view matches currentItemIndex.

例如:

// Current index
NSInteger currentIndex = myCarousel.currentItemIndex;

// Current view
UIView *currentView = myCarousel.currentItemView;
