UICollectionView Cell nib not loading
提问by isal
I'm using a custom subclass of UICollectionViewFlowLayoutthat allows reordering of cells. Source code here.
我正在使用UICollectionViewFlowLayout允许重新排序单元格的自定义子类。源代码在这里。
The issue I am running into is that the nib file I created for the Collection View does not load despite registering it and using the correct identifier. Here are the relevant code snippets.
我遇到的问题是，尽管注册并使用了正确的标识符，但我为集合视图创建的 nib 文件没有加载。以下是相关的代码片段。
This is in the view controller .mfile:
这是在视图控制器.m文件中：
- (void)loadView
{
self.reorderLayout = [[LXReorderableCollectionViewFlowLayout alloc] init];
self.collectionView = [[UICollectionView alloc] initWithFrame:CGRectZero
collectionViewLayout:self.reorderLayout];
UINib *nib = [UINib nibWithNibName:@"CatagoryViewCell" bundle:nil];
[self.collectionView registerNib:nib forCellWithReuseIdentifier:@"CatagoryViewCellID"];
self.collectionView.dataSource = self;
self.collectionView.delegate = self;
}
- (UICollectionViewCell *)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath
{
Catagory *c = [[[CatagoryStore defaultStore] allCatagories]
objectAtIndex:[indexPath item]];
CatagoryViewCell *cell = (CatagoryViewCell *)[collectionView dequeueReusableCellWithReuseIdentifier:@"CatagoryViewCellID" forIndexPath:indexPath];
[cell setController:self];
[[cell nameLabel] setText:c.title];
return cell;
}
These are the only two places I reference the nib.
这是我提到笔尖的仅有的两个地方。
Here is the cell nib:
这是细胞笔尖：
This is what it looks like in the simulator and device:
这是模拟器和设备中的样子：
I tried using similar code and the original UICollectionViewFlowLayoutclass and it works fine. Any insight is greatly appreciated!
我尝试使用类似的代码和原始UICollectionViewFlowLayout类，它工作正常。非常感谢任何见解！

Try with this "initWithFrame" methods inside your CollectionViewCell.m
尝试在 CollectionViewCell.m 中使用此“initWithFrame”方法
-(id)initWithFrame:(CGRect)frame {
self = [super initWithFrame:frame];
if (self) {
NSString *cellNibName = @"YourCollectionViewCell";
NSArray *resultantNibs = [[NSBundle mainBundle] loadNibNamed:misVentasCellNibName owner:nil options:nil];
if ([resultantNibs count] < 1) {
return nil;
}
if (![[resultantNibs objectAtIndex:0] isKindOfClass:[UICollectionViewCell class]]) {
return nil;
}
self = [resultantNibs objectAtIndex:0];
}
return self;
}
Then in the class you have de collection view add:
然后在类中你有 de collection view 添加：
[collectionView registerClass:[YourCollectionViewCell class] forCellWithReuseIdentifier:@"YourCollectionViewCell"];
And Finally
最后
- (UICollectionViewCell *)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath {
// Setup cell identifier
static NSString *cellIdentifier = @"YourCollectionViewCell";
YourCollectionViewCell *cell = (YourCollectionViewCell *)[cvArticles dequeueReusableCellWithReuseIdentifier:cellIdentifier forIndexPath:indexPath];
}
Remember you must insert in your.xib the same cellIdentifier you are using in the Identifier field of the Collection view!!!!!!!!
请记住，您必须在您的.xib 中插入您在 Collection 视图的 Identifier 字段中使用的相同 cellIdentifier！！！！！！！！！
