但是有问题:(
2016-05-21 20:36:53.108 [13794:5338746] the behavior of the
UICollectionViewFlowLayout is not defined because:
2016-05-21 20:36:53.109 [13794:5338746] the item height must
be less than the height of the UICollectionView minus the
section insets top and bottom values, minus the content insets
top and bottom values.
2016-05-21 20:36:53.109 [13794:5338746] Please check the values
return by the delegate.
2016-05-21 20:36:53.110 [13794:5338746] The relevant
UICollectionViewFlowLayout instance is <UICollectionViewFlowLayout: 0x137c836e0>,
and it is attached to <XLPagerTabStrip.ButtonBarView: 0x13715ec00;
baseClass = UICollectionView; frame = (0 66; 375 45);
clipsToBounds = YES; autoresize = RM+BM;
gestureRecognizers = <NSArray: 0x137c82f30>;
layer = <CALayer: 0x137c64ff0>; contentOffset: {0, 0};
contentSize: {239.5, 128}> collection view layout:
<UICollectionViewFlowLayout: 0x137c836e0>.
2016-05-21 20:36:53.110 [13794:5338746] Make a symbolic breakpoint
at UICollectionViewFlowLayoutBreakForInvalidSizes to catch
this in the debugger.
我找不到任何解决方案。有人知道这个吗？
