ios - UICollectionViewCell加载问题？

Question

在UIViewController里定义了一个UICollectionView，注册cell

UIViewController.h里面

@property (weak, nonatomic) IBOutlet UICollectionView *pictureCollection;

UIViewController.m里面

[self.pictureCollection registerClass:[CAPictureCell class] forCellWithReuseIdentifier:@"capicture"];

加载cell的代码

-(UICollectionViewCell )collectionView:(UICollectionView )collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath{

CAPictureCell *cell = [collectionView dequeueReusableCellWithReuseIdentifier:@"capicture" forIndexPath:indexPath];
if (cell==nil) {
    cell=[[CAPictureCell alloc]init];
}
NSDictionary *dic = [[NSDictionary alloc] init];
[cell setInfo:dic];
return cell;

}

CAPictureCell.m文件里面

• (void)setInfo:(NSDictionary*)d{

  self.backgroundColor = [UIColor redColor];
  [self.CAPicture setImage:[UIImage imageNamed:@"logoGrey.png"]];
  self.CALabel.text = @"222";

  }

想要实现cell

目前只有backgroundColor出来了

求助。

Answer 1

加断点，看setInfo有么有走到

Answer 2

如果你是用 nib/storyboard 做的 cell，不要用：

[self.pictureCollection registerClass:[CAPictureCell class] forCellWithReuseIdentifier:@"capicture"];

而是：

UINib *cellNib = [UINib nibWithNibName:<#Your Nib File#> bundle:nil];
[self.tableView registerNib:cellNib forCellReuseIdentifier:@"capicture"];
