2 years ago - (void)scrollToIndex:(int)targetIndex { if (targetIndex >= _totalItemsCount) { if (self.infiniteLoop) { targetIndex = _totalItemsCount * 0.5; [_mainView scrollToItemAtIndexPath:[NSIndexPath indexPathForItem:targetIndex inSection:0] atScrollPosition:UICollectionViewScrollPositionNone animated:NO]; } return; } [_mainView scrollToItemAtIndexPath:[NSIndexPath indexPathForItem:targetIndex inSection:0] atScrollPosition:UICollectionViewScrollPositionNone animated:YES]; } 如上， [_mainView scrollToItemAtIndexPath:[NSIndexPath indexPathForItem:targetIndex inSection:0] atScrollPosition:UICollectionViewScrollPositionNone animated:YES]会导致内存泄漏，麻烦修复，谢谢
