使用xcode15运行工程，控制台会出现如下提示：

Expected dequeued view to be returned to the collection view in preparation for display. When the collection view's data source is asked to provide a view for a given index path, ensure that a single view is dequeued and returned to the collection view. Avoid dequeuing views without a request from the collection view. For retrieving an existing view in the collection view, use -[UICollectionView cellForItemAtIndexPath:] or -[UICollectionView supplementaryViewForElementKind:atIndexPath:]. Dequeued view: <IQEngUICollectionViewCell: 0x130215e00; baseClass = UICollectionViewCell; frame = (396 0; 396 98.1547); clipsToBounds = YES; backgroundColor = UIExtendedGrayColorSpace 0 0; layer = <CALayer: 0x301e371a0>>; Collection view: <UICollectionView: 0x1300caa00; frame = (0 0; 396 98.1547); clipsToBounds = YES; gestureRecognizers = <NSArray: 0x300b706f0>; backgroundColor = <UIDynamicSystemColor: 0x3002a3380; name = systemBackgroundColor>; layer = <CALayer: 0x301d5a080>; contentOffset: {0, 0}; contentSize: {3168, 98.154666666666671}; adjustedContentInset: {0, 0, 0, 0}; layout: <IQEngCollectionViewFlowLayout: 0x1237e7480>; dataSource: IQEngCarouselView:<IQEngCarouselView: 0x130117e00; frame = (16 11.4133; 396 98.1547); clipsToBounds = YES; layer = <CALayer: 0x301d59f20>>>  This will become an assert in a future version.

然后在xcode16运行是会直接闪退的，控制台会显示

*** Assertion failure in -[UICollectionView _updateVisibleCellsNow:], UICollectionView.m:5673

问题原因在于，轮播图在自动轮播的时候调用的方法有问题

这个代码是有问题的    
UICollectionViewCell *cell = [self collectionView:self.collectionView cellForItemAtIndexPath:indexPath];CGFloat f1_minX = cell.frame.origin.x;CGPoint point = CGPointZero;point.x = f1_minX;CGPoint nextPoint = [self.collectionViewLayout targetContentOffsetForProposedContentOffset:point withScrollingVelocity:CGPointZero];[self.collectionView setContentOffset:nextPoint animated:animated];

将上面代码换成

    [self.collectionView scrollToItemAtIndexPath:indexPathatScrollPosition:UICollectionViewScrollPositionLeftanimated:animated];

可以解决问题
