iOS: UICollectionViewcell里面的图片不能加载

跟实例基本差不多,但每次都显示image对象为nil,请问大神哪里有问题?

  • (NSInteger) numberOfSectionsInCollectionView:(UICollectionView *)collectionView
    {
    return 1;
    }

  • (NSInteger) collectionView:(UICollectionView *)collectionView numberOfItemsInSection:(NSInteger)section
    {
    return 1;
    }

-(UICollectionViewCell *) collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath
{
ImageCell *cell = [collectionView dequeueReusableCellWithReuseIdentifier:@"Cell" forIndexPath:indexPath];
// UIImage *testImage = [UIImage imageNamed:@"4.JPG"];
cell.image.image = [UIImage imageNamed:@"4.JPG"];
return cell;
}

你的cell.image应该是UIImageView吧 如果是UIImageView的话,先把你的名称改了,image太特殊了,容易与系统命名重名,这句demo我感觉你应该用SDWebimage cell.image = [[UIImageView alloc]initWithImage:[UIImage imageNamed:@"4.JPG"]];
