alasset

I want to play multiple videos in infinite loop in my collection view. Each Video represent a cell. I am using ALAsset. I am playing this using AVPLayer but it's not loading and playing smoothly. Any Suggestions. - (UICollectionViewCell *)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath { UICollectionViewCell *cell = [collectionView dequeueReusableCellWithReuseIdentifier:@"cellIdentifier" forIndexPath:indexPath]; CGRect attachmentFrame = CGRectMake(2, 2, cell.frame.size.width-4, cell.frame.size.height-4); ALAsset *asset = self.assets[indexPath

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 am actually creating an iOS app, and want to store some details about Photo Library pictures in an SQLite database. I also would like to be able to share this data across the different devices the user has (imagine someone wanted to reorganize pictures on his iPhone, and wants to retrieve the same order in his iPad). I have searched across the Apple documentation, but did not find any PHAsset identifier that is shared across devices. I also tried to check if the PHImageFileURLKey , hashValue , or localIdentifier of the PHAsset where shared, but none of them are. Has someone already done

iOS 8 broke lots of apps by removing "Camera Roll" from the ALAssetsLibrary enumerating API. I know I can get all photos using the new Photos framework. But my app has a lot of code depending on ALAsset related classes and I need to keep iOS 7 support. Is there a way to enumerate all photos using ALAssetsLibary on iOS 8, without enumerating asset group first? Apple just released 8.0.1 and listed this as a included fix. Might just be best to wait for that. From the 8.0.1 release notes: Fixes an issue that prevented some apps from accessing photos from the Photo Library 来源： https://stackoverflow

I can get images from Photo Library through ALAssetsLibrary: void (^assetEnumerator)(ALAsset *, NSUInteger, BOOL *) = ^(ALAsset *result, NSUInteger index, BOOL *stop){ if([[result valueForProperty:ALAssetPropertyType] isEqualToString:ALAssetTypePhoto]) { // Copy the photo image to the `/Documents` directory of this App here } }; void (^assetGroupEnumerator )(ALAssetsGroup*, BOOL*) = ^(ALAssetsGroup *group, BOOL *stop){ if (group != nil) { [group enumerateAssetsUsingBlock:assetEnumerator]; } }; // fetch ALAssetsLibrary *library = [ALAssetsLibrary new]; [library enumerateGroupsWithTypes

Right now, I am using the ALAssetsLibrary to gather the photos from ALAssetsGroupSavedPhotos and ALAssetsGroupLibrary. Upon reading all the assets into an array, I populate my UITableView ([myTable reloadData]) to show the photos. I find that if the user has many photos, there is an increasing amount of delay. Is there any way to possible speed things up? The default UIIMagePicker seems to have no delay at all, despite the number of photos in the Camera Roll or PhotoLibrary. Is there any way to attain the same speed? Thank you! Just enumerate the assets you currently need to display by using

I am trying to create a method that will return me a ALAsset for a given asset url. (I need upload the asset later and want to do it outside the result block with the result.) + (ALAsset*) assetForPhoto:(Photo*)photo { ALAssetsLibrary* library = [[[ALAssetsLibrary alloc] init] autorelease]; __block ALAsset* assetToReturn = nil; NSURL* url = [NSURL URLWithString:photo.assetUrl]; NSLog(@"assetForPhoto: %@[", url); [library assetForURL:url resultBlock:^(ALAsset *asset) { NSLog(@"asset: %@", asset); assetToReturn = asset; NSLog(@"asset: %@ %d", assetToReturn, [assetToReturn retainCount]); }
