How do I get the data from UIImagePickerControllerReferenceURL?

Question

I am using ELCImagePickerController in my app and I don\'t want to save the selected fullScreenImage to my array because if i selected 40 iPad images then that is not good.

Answer 1

in ELCImagePickers "Selected assets" you can do

-(void)selectedAssets:(NSArray*)_assets {

"... your code .?.?."

    NSMutableArray *returnArray = [[NSMutableArray alloc] init];

    for(ALAsset *asset in _assets) {

        NSMutableDictionary *workingDictionary = [[NSMutableDictionary alloc] init];
        [workingDictionary setObject:[[asset valueForProperty:ALAssetPropertyURLs] valueForKey:[[[asset valueForProperty:ALAssetPropertyURLs] allKeys] objectAtIndex:0]] forKey:@"UIImagePickerControllerReferenceURL"];

".. any other properties you need ?"

        [returnArray addObject:workingDictionary];

    }
}

Then in your other class to save from array

- (void) importImagesFromArray:(NSArray *)_images toFolder:(NSString *)folderPath
{
   if ([_images count] > 0) {

    //... YOUR CODE HERE FOR CHECKING YOUR ARRAY...Maybe a loop or something//
    //
    //
    //

    //ex:

ALAssetsLibrary *library = [[ALAssetsLibrary alloc] init];
    for (NSDictionary *dict in _images) {



        [library assetForURL:[dict objectForKey:@"UIImagePickerControllerReferenceURL"]
                 resultBlock:^(ALAsset *asset){

                     //You Can Use This

                     UIImage *theImage = [UIImage imageWithCGImage:[[asset defaultRepresentation] fullResolutionImage]
                                                             scale:1.0
                                                       orientation:[[asset valueForProperty:@"ALAssetPropertyOrientation"] intValue]];

                     //[....save image blah blah blah...];

                     ///////////////////////////////////////////////////
                     ///////////////////////////////////////////////////

                     ////// OR YOU CAN USE THIS////////////////////

                     ALAssetRepresentation *rep = [asset defaultRepresentation];
                     Byte *buffer = (Byte*)malloc(rep.size);
                     NSUInteger buffered = [rep getBytes:buffer fromOffset:0.0 length:rep.size error:nil];
                     NSData *data = [NSData dataWithBytesNoCopy:buffer length:buffered freeWhenDone:YES];//this is NSData may be what you want
                     [data writeToFile:[folderPath stringByAppendingPathComponent:@"Some Filename You Need To Assign"] atomically:YES];


                 }

                failureBlock:^(NSError *error){
                    NSLog(@"Error saving image");

                }];

        // Dont forget to release library

    }
}
}
