Displaying images in UICollectionViewCell from database in iOS

Anonymous User 1558 30-Nov-2015

I am a beginner in iPhone app development, I want to display image in UICollectionViewCell from using database.
In our programming I am using code like this :

SqliteDB *images;
images = [SQliteDB alloc] init];
imgArray = [images OpenMyDatabase: @"SELECT images FROM exterior" :
                                   @"images"];

So, my problem is how can I display those images?

Use my code to display UIImage grid. and add uicollectionView in your xib file.

- (NSInteger)numberOfSectionsInCollectionView:(UICollectionView *)collectionView {
   return  1;
}
- (NSInteger)collectionView:(UICollectionView *)collectionView numberOfItemsInSection:(NSInteger)section {
   return [imgArray count];
}
- (UICollectionViewCell *)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath {
   static NSString *identifier = @"Cell";
   UICollectionViewCell *cell = [collectionView dequeueReusableCellWithReuseIdentifier:
 identifier forIndexPath:indexPath];
   UIImageView *imgView = (UIImageView *)[cell viewWithTag:100];
   imgView.image = [UIImage imageNamed:[imgArray objectAtIndex:indexPath.row]];
   return cell;
}

and, don't forget to set delegate in collection before using that code.
and also in your xib file add UIImageView to your collection view cell and set its tag value to 100.
