makeScrollViewScrollToIndex 这个方法 是什么意思?大问题呀,算法有问题

[LoSenTrad]

看源码 为啥要进行传进来的index 的换算? 大家都没发现这个问题?

简单解决了，随便看看吧！重写了个方法makeScrollToIndex:

• (void)makeScrollViewScrollToIndex:(NSInteger)index { if (self.autoScroll) { [self invalidateTimer]; } if (0 == _totalItemsCount) return;

  [self makeScrollToIndex:index];

  if (self.autoScroll) { [self setupTimer]; } }

• (void)makeScrollToIndex:(NSInteger)targetIndex { if (self.infiniteLoop) { targetIndex = targetIndex%(_totalItemsCount/100); targetIndex = _totalItemsCount * 0.5 + targetIndex; if (targetIndex < [self currentIndex]) { [_mainView scrollToItemAtIndexPath:[NSIndexPath indexPathForItem:(_totalItemsCount * 0.5 -1) inSection:0] atScrollPosition:UICollectionViewScrollPositionNone animated:NO]; } }else if (targetIndex >= _totalItemsCount){ return; } [_mainView scrollToItemAtIndexPath:[NSIndexPath indexPathForItem:targetIndex inSection:0] atScrollPosition:UICollectionViewScrollPositionNone animated:YES]; }

好的 我自己改了源码 啊哈
