How to display multiselected images in iOS

Question

I am making an app for iPhone and want to give users the ability to multiselect images from their photo-library. I already have a working code for user to select four images at a time.

But I can't select 1 or 2 or 3 images at a time. I want to select the 1 or 2 or 3 images at a time.

This is my code. I have struggled for 3 days without finding a solution. Please help me anybody.

Thanks in advance.............

-(void)choosePhotoFromExistingImages
{   
    ELCImagePickerController *elcPicker = [[ELCImagePickerController alloc] initImagePicker];   
    elcPicker.maximumImagesCount = 4;   
    elcPicker.returnsOriginalImage = NO; //Only return the fullScreenImage, not the fullResolutionImage 
    elcPicker.imagePickerDelegate = self; 
    [self presentViewController:elcPicker animated:YES completion:nil];   
}

- (void)imagePickerControllerDidCancel:(UIImagePickerController *)picker
{    
    [self.navigationController dismissViewControllerAnimated: YES completion: nil];
}

- (void)displayPickerForGroup:(ALAssetsGroup *)group
{   
    ELCAssetTablePicker *tablePicker = [[ELCAssetTablePicker alloc] initWithStyle:UITableViewStylePlain];   
    tablePicker.singleSelection = YES;  
    tablePicker.immediateReturn = YES;    
    ELCImagePickerController *elcPicker = [[ELCImagePickerController alloc] initWithRootViewController:tablePicker];   
    elcPicker.maximumImagesCount = 0;   
    elcPicker.imagePickerDelegate = self;   
    elcPicker.returnsOriginalImage = NO; //Only return the fullScreenImage, not the fullResolutionImage 
    tablePicker.parent = elcPicker;

    // Move me   
    tablePicker.assetGroup = group;
    [tablePicker.assetGroup setAssetsFilter:[ALAssetsFilter allAssets]];
    [self presentViewController:elcPicker animated:YES completion:nil];
}

Answer 1

Check your code in - (void)elcImagePickerController:(ELCImagePickerController *)picker didFinishPickingMediaWithInfo:(NSArray *)info

For example, you create array with length of 2, but in code below you try to get image3.image=[images objectAtIndex:2]; and image4.image=[images objectAtIndex:3];. It's not a surprise that your code throws exception.

Good luck!
