cellForItemAtIndexPath未调用但numberOfItemsInSection确实调用了 [英] cellForItemAtIndexPath not called but numberOfItemsInSection does
问题描述
这可能是一个重复的帖子,但我没有找到任何一个解决方案:
This could be a duplicate post but I haven't found the solution in any of this:
我正在设置我的 UICollectionView
as:
I'm setting my UICollectionView
as:
UINib *nib = [UINib nibWithNibName:@"CollectionViewCell"
bundle:[NSBundle mainBundle]];
[_collectionView registerNib: nib forCellWithReuseIdentifier:@"bCell"];
(我试图设置委托,没有委托,等等)。
(I've tried to set delegate, without delegate, etcetera).
但是,只有
- (NSInteger)collectionView:(UICollectionView *)collectionView numberOfItemsInSection:(NSInteger )
- (NSInteger)collectionView:(UICollectionView *)collectionView numberOfItemsInSection:(NSInteger)section
gets called while
- (UICollectionViewCell *)collectionView :( UICollectionView *)collectionView cellForItemAtIndexPath :( NSIndexPath *) )indexPath
没有。
我检查了 numberOfItemsInSection 我返回,它总是> 0(它正好是17)。
I've checked the numberOfItemsInSection I return, and it's always > 0 (it's exactly 17).
我已经检查过调用 [_ collectionView reloadData];
并且没有任何反应。
I've checked to call [_collectionView reloadData];
and nothing happens either.
我尝试了不同的东西,但我无法使其发挥作用。
I've tried different things but I can't make it work.
此外,我的 UICollectionView
应该在这里,但不是:
Furthermore, my UICollectionView
should be here but it's not:
有没有人有一个线索?
谢谢。
Does anyone have a clue? Thank you.
推荐答案
好的我认为这对今后的问题有用...
Ok I think this could be useful for future problems with this...
这是因为StoryBoard的限制。我真的不明白为什么会这样,因为我刚刚固定了一个水平空间。我删除了水平空间作为该视图的约束,一切正常。
It was because of constraints on the StoryBoard. I don't really understand why that happens, because I just had fixed an horizontal space. I removed the horizontal space as constraint for that View and everything works fine.
好吧,让我们的生命流。
Well, let's life flow.
