alassetslibrary

I iterate through a list of photo albums on a iOS device. After having iterated through this group I want to simply print out the number of albums that were found. What do I have to change in my code that the NSLog statement is only executed, when all the albums were loaded. ALAssetsLibrary *library = [[ALAssetsLibrary alloc] init]; NSMutableArray *tempArray = [[NSMutableArray alloc] init]; void (^groupBlock)(ALAssetsGroup *, BOOL *) = ^(ALAssetsGroup *group, BOOL *stop){ if (group == nil){return;} [tempArray addObject:group]; }; void (^failureBlock)(NSError *) = ^(NSError *error) { NSLog(@"A

I am handling with the ALAssetsLibrary. When I get all the thumbnails, I just use the UIImageViews to hold the thumbnails and add them to the holder. Problem is here, it is really slow to add them. Maybe ten seconds or more. If there is much photos, it will be slower. I would want to know what is the best practice to hold these thumbnails. (Many thanks!) Shamsudheen TK Use AlAsset aspectRatioThumbnail instead of fullResolutionImage for high performance The class ALAsset has two methods to get thumbnails: - (CGImageRef)thumbnail - (CGImageRef)aspectRatioThumbnail example: //ALAssetsLibrary

I trying to retrive images from Photo Library & display in my app using AssetsLibrary. I got the URL path of photos but I don't know how to get photo through it. My Code is as Follow: NSMutableArray* assetURLDictionaries = [[NSMutableArray alloc] init]; void (^assetEnumerator)( ALAsset *, NSUInteger, BOOL *) = ^(ALAsset *result, NSUInteger index, BOOL *stop) { if(result != nil) { if([[result valueForProperty:ALAssetPropertyType] isEqualToString:ALAssetTypePhoto]) { [assetURLDictionaries addObject:[result valueForProperty:ALAssetPropertyURLs]]; NSLog(@"result is:%@",result); NSLog(@"asset

Given an ALAsset that represents a photo, is it possible to retrieve the size of the photo (height and width) without loading the image into a UIImageView and also without using the aspectRationThumnail method? Just a note: iOS 5.1 introduces a new property dimensions for an ALAssetRepresentation instance. This returns a CGSize structure with the dimensions of the original image and might be the best solution for this problem in the future. Cheers, Hendrik float width = asset.defaultRepresentation.dimensions.width; float height = asset.defaultRepresentation.dimensions.height; it fast, stable,

I am trying to write a method that read assets from a album I am getting all images from all album using ALAsset, my question is how can I customize this method to read images from myAlbum /** * This method is used to get all images from myAlbum * folder in device if getAlbumImages is set to 1 * else loads all images from devices library */ -(void)readImages:(int)getAlbumImages { imageArray = [[NSArray alloc] init]; mutableArray =[[NSMutableArray alloc]init]; NSMutableArray* assetURLDictionaries = [[NSMutableArray alloc] init]; library = [[ALAssetsLibrary alloc] init]; if(getFolderImages == 1)

I'm developing a camera application where I'd like to put some functions that are already present in the stock app. My problem is replicating the little square in the bottom left corner (in portrait mode) where the micro-thumbnail of the photo that the user has just taken is shown; then, when the user tap on it, the photo app should open, on the last photo saved in the camera roll. I can load the thumbnail of the newest photo in camera roll with ALAssetsLibrary - I've access to it with [UIImage imageWithCGImage:[result thumbnail]] - but even if I have its ALAsset URL, I can't open the photo

I tried below code to get all videos from photo library by using ALAsset . For now, i want to display all videos to a UICollectionview but it doesn't seem to display anything. Please give me some advice. Thanks in advance. -ViewDidLoad() : get all videos from Photo Library allVideos = [[NSMutableArray alloc] init]; ALAssetsLibrary *assetLibrary = [[ALAssetsLibrary alloc] init]; [assetLibrary enumerateGroupsWithTypes:ALAssetsGroupAll usingBlock:^(ALAssetsGroup *group, BOOL *stop) { if (group) { [group setAssetsFilter:[ALAssetsFilter allVideos]]; [group enumerateAssetsUsingBlock:^(ALAsset *asset
