Question

我有一个UICollectionView。没有缓存，因为到目前为止我还没有需要应用，只有7个不同的图像，但可能有40个单元格。我对这种方法也没有经验。

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

UICollectionViewCell *cell=[collectionView dequeueReusableCellWithReuseIdentifier:@"Cell" forIndexPath:indexPath];

UIImageView *collectionImageView = (UIImageView *)[cell viewWithTag:102];
UILabel *ballLabel = (UILabel *)[cell viewWithTag:103];
UILabel *ballLabelInfo = (UILabel *)[cell viewWithTag:110];

ballShot *selectedBall = [self.statsView.visitBallShotCollection objectAtIndex:indexPath.row];

NSString *ballDetail;
NSString *labelInfo;



ballDetail = [NSString stringWithFormat:@"Foul"];
labelInfo = [NSString stringWithFormat:@"%@",[selectedBall getFoulTypeText:selectedBall.foulid]];

collectionImageView.image = [UIImage imageNamed:selectedBall.imageNameLarge];
ballLabel.text = ballDetail;
ballLabelInfo.text = labelInfo;


return cell;
}

我能够使用正确的内容大小保存UICollectionView的显示内容，但不能保存整个内容。

- (UIImage *) imageWithCollectionView:(UICollectionView *)collectionBreakView
{
CGSize widthHeight = CGSizeMake(collectionBreakView.contentSize.width, collectionBreakView.contentSize.height);
UIGraphicsBeginImageContextWithOptions(widthHeight, collectionBreakView.opaque, 0.0);
[collectionBreakView.layer renderInContext:UIGraphicsGetCurrentContext()];
UIImage * img = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
return img;
}

如何获取整个内容并放入UIImage？如果缓存是答案，有人可以给我一个启动设置吗？提前谢谢。
