Question

Je suis nouveau sur Photo framework je ne sais pas comment l'utiliser. J'ai utilisé beaucoup de liens mais j'ai confondu comment afficher l'image en imageview.

Je veux obtenir le tout photo de la galerie en utilisant cadre photo je suis en train

NSMutableOrderedSet *recentsDataSource; 
PHFetchResult *assetCollection = [PHAssetCollection fetchAssetCollectionsWithType:PHAssetCollectionTypeSmartAlbum | PHAssetCollectionTypeAlbum subtype:PHAssetCollectionSubtypeAny options:nil]; 
    for (PHAssetCollection *sub in assetCollection) 
    { 
     PHFetchResult *assetsInCollection = [PHAsset fetchAssetsInAssetCollection:sub options:nil]; 

     for (PHAsset *asset in assetsInCollection) 
     { 
      [self.recentsDataSource addObject:asset]; 
     } 
    } 

    if (self.recentsDataSource.count > 0) 
    { 
     NSArray *array = [self.recentsDataSource sortedArrayUsingDescriptors:@[[NSSortDescriptor sortDescriptorWithKey:@"creationDate" ascending:NO]]]; 
     NSLog(@"Photo Array : %@",array); 
     self.recentsDataSource = [[NSMutableOrderedSet alloc]initWithArray:array]; 
    } 

i ont obtenir ce type de tableau.

Comment afficher les images sur une visualisation.

Answer 1

Ajouter ce dans .h/fichier .m

#import <Photos/Photos.h> 

Variable globale:

@property(nonatomic , strong) PHFetchResult *assetsFetchResults; 
@property(nonatomic , strong) PHCachingImageManager *imageManager; 

Code viewDidLoad:

// Fetch all assets, sorted by date created. 
    PHFetchOptions *options = [[PHFetchOptions alloc] init]; 
    options.sortDescriptors = @[[NSSortDescriptor sortDescriptorWithKey:@"creationDate" ascending:NO]]; 
    _assetsFetchResults = [PHAsset fetchAssetsWithOptions:options]; 

    _imageManager = [[PHCachingImageManager alloc] init]; 

méthode numberOfItemsInSection:

- (NSInteger)collectionView:(UICollectionView *)collectionView numberOfItemsInSection:(NSInteger)section 
{ 
    return [_assetsFetchResults count]; 
} 

UICollectionView cellForItemAtIndexPath: Code:

UICollectionViewCell *cell = [collectionView dequeueReusableCellWithReuseIdentifier:@"cellID" forIndexPath:indexPath]; 

UIImageView *imageView = (UIImageView *)[cell viewWithTag:101]; 
PHAsset *asset = _assetsFetchResults[indexPath.item]; 

     [_imageManager requestImageForAsset:asset targetSize:imageView.frame.size contentMode:PHImageContentModeAspectFill options:nil resultHandler:^(UIImage *result, NSDictionary *info) 
     { 
      imageView.image = result; 
     }];

accès à l'image:

- (void)collectionView:(UICollectionView *)collectionView didSelectItemAtIndexPath:(NSIndexPath *)indexPath 
{ 
    PHAsset *asset = _assetsFetchResults[indexPath.item]; 

    [_imageManager requestImageForAsset:asset targetSize:CGSizeMake(200, 200) contentMode:PHImageContentModeAspectFill options:nil resultHandler:^(UIImage *result, NSDictionary *info) 
     { 
      // result is the actual image object. 
     }]; 
}
