When I am fetching photos using the ALAssetLibrary, for some images, the AssetRepresentation.size comes zero, which does not make the image, on my ImageView. Here is the code:
ALAssetsLibrary *library = [[ALAssetsLibrary alloc] init];
[library enumerateGroupsWithTypes:ALAssetsGroupAlbum usingBlock:^(ALAssetsGroup *group, BOOL *stop) {
if ([[group valueForProperty:ALAssetsGroupPropertyName] isEqual:self.groupName]) {
[group enumerateAssetsUsingBlock:^(ALAsset *result, NSUInteger index, BOOL *stop){
//Get the asset type
NSString *assetType = [result valueForProperty:ALAssetPropertyType];
if ([assetType isEqualToString:ALAssetTypePhoto]) {
NSLog(@"Photo Asset");
}
//Get URLs for the assets
NSDictionary *assetURLs = [result valueForProperty:ALAssetPropertyURLs];
NSUInteger assetCounter = 0;
for (NSString *assetURLKey in assetURLs) {
assetCounter++;
}
//Get the asset's representation object
ALAssetRepresentation *assetRepresentation = [result defaultRepresentation];
//From this asset representation, we take out data for image and show it using imageview.
dispatch_async(dispatch_get_main_queue(), ^(void){
CGImageRef imgRef = [assetRepresentation fullResolutionImage];
//Img Construction
UIImage *image = [[[UIImage alloc] initWithCGImage:imgRef] autorelease];
NSLog(@"before %@:::%lld", [image description], [assetRepresentation size]); //Prints '0' for size
if((image != nil)&& [assetRepresentation size] != 0){
//display in image view
}
else{
// NSLog(@"Failed to load the image.");
}
});
}];
}
}failureBlock:^(NSError *error){
NSLog(@"Error retrieving photos: %@", error);
}];
[library release];
Please Help. What am I doing wrong here? and how should I get the image?
