如何解决 UICollectionViewFlowLayoutBreakForInvalidSizes

如何解决如何解决 UICollectionViewFlowLayoutBreakForInvalidSizes

我找不到这个问题的答案,也许是因为我的代码不同,我不知道,但最后,我没有找到答案,collectionView 一直抱怨 UICollectionViewFlowLayoutBreakForInvalidSizes 并希望我抓住错误符号断点,但我即使断点调试器也没有显示有关错误的任何信息,这是我实现 collectionView 的方法,如果有人能在我的代码中找到问题,请告诉我

The relevant UICollectionViewFlowLayout instance is <UICollectionViewFlowLayout: 0x7f86d50a9b70>,and it is attached to <UICollectionView: 0x7f86d4944000; frame = (0 61; 414 317); clipsToBounds = YES; gestureRecognizers = <NSArray: 0x600002e397a0>; layer = <CALayer: 0x60000201b120>; contentOffset: {-5,1169.5}; contentSize: {404,1557.1875}; adjustedContentInset: {5,5,5}; layout: <UICollectionViewFlowLayout: 0x7f86d50a9b70>; dataSource: <DELEVARE___ÿØŸäŸÑŸäŸÅÿ±Ÿä.DriverChat: 0x7f86d4849c00>>. 2021-01-16 17:57:24.377551+0200 DELEVARE - ديليفري[63548:1297733] Make a symbolic breakpoint at UICollectionViewFlowLayoutBreakForInvalidSizes to catch this in the debugger.
