• (void)viewDidLoad
  {

  // self.collectionView
  self.collectionview.delegate = self;
  self.collectionview.dataSource = self;
  [self.collectionview registerClass: [ImageCell class] forCellWithReuseIdentifier:@"Cell"];
  // self.collectionview.dataSource = self;
  // Do any additional setup after loading the view, typically from a nib.

  }

#pragma Collection View Data Souce

• (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;
}

#pragma custommethod

@end

解决方案

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"]];

解决方案二：
