Answer 1

我沒有測試過什麼，我要寫，但你可以試試這個：

-(void)viewDidLoad { 

    //declare before NSMutableArray *_mutableArray; 
    _mutableArray = [[NSMutableArray alloc] init]; 
} 

... 

-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info { 
    //dismiss UIImagePickerController 
    [picker dismissViewControllerAnimated:YES completion:Nil]; 

    //take image from info 
    UIImage *image = [info objectForKey:UIImagePickerControllerOriginalImage]; 

    //store image into NSMutableArray 
    [_mutableArray addObject:image]; 

    //reload collectionView 
    [self.collectionView reloadData]; 
} 

和collectionView cellForItemAtIndexPath

- (UICollectionViewCell *)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath 
{ 
    //this is a custom CollectionViewCell 
    CollectionCell *cell = [collectionView dequeueReusableCellWithReuseIdentifier:@"Cell" forIndexPath:indexPath]; 

    cell.imageA.image = [_mutableArray objectAtIndex:indexPath.row]; 

    return cell; 

}
