您如何通过Parse.com查找1张以上的图像

Question

Following this Question/Answer

https://www.parse.com/questions/pfquerytableviewcontroller-segue

I would like to know how do you set the code on passing more than 1 image. Is there a way to make the UIImageView Reusable? (Like a CollectionView Cell)

This would be the code to follow for 1 Image coming from the cell clicked.

EDITED CODE:

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

static NSString *cellIdentifier = @"Cell";
VestimentaDetailCell *cell = (VestimentaDetailCell *) [collectionView dequeueReusableCellWithReuseIdentifier:cellIdentifier forIndexPath:indexPath];

static int index = 1;

PFFile *imageFile = [self.vestimenta objectForKey: [NSString stringWithFormat:@"image_%d", index++]];

[imageFile getDataInBackgroundWithBlock:^(NSData *data, NSError *error) {
if (!error) {

cell.imageFile.image = [UIImage imageWithData:data];


}
}];

return cell;
}

How can I make the cell reusable and show more images?

Thank you.

It sounds like you're asking if you can change the image that's installed in an image view once it's been created? If so, the answer is most definitely yes.

You can replace the image in an image view as many times as you want. The same goes for the images loaded into buttons, but you have to use a special method for that.
