Question

i have created a album in my photo library using this code
NSString *albumName=#"iphonemaclover";
ALAssetsLibrary *library = [[ALAssetsLibrary alloc] init];
[library addAssetsGroupAlbumWithName:albumName
resultBlock:^(ALAssetsGroup *group) {
NSLog(#"added album:%#", albumName);
AND
I have download the video from server using this code
-(IBAction)btnDownload:(UIView *)sender {
[DSBezelActivityView newActivityViewForView:self.view withLabel:#"DOWNLOADING..."];
NSString *albumName=#"album name";
NSURL *url = [NSURL URLWithString:#"http://www.ebookfrenzy.com/ios_book/movie/movie.mov"];
ASIHTTPRequest *request = [ASIHTTPRequest requestWithURL:url];
[request setDelegate:self];
[request setDownloadDestinationPath:#"/Users/seemtech/Desktop/dd/vvv.m4v"];//work fine
[ASIHTTPRequest setDefaultTimeOutSeconds:3000];
[request startAsynchronous];
}
failureBlock:^(NSError *error) {
NSLog(#"error adding album");
}];
}
-(void)requestFinished:(ASIHTTPRequest *)request
{
[[[[UIAlertView alloc] initWithTitle:#"Message"
message:#"Success!!!"
delegate:self
cancelButtonTitle:#"OK"
otherButtonTitles:nil] autorelease] show]; [DSBezelActivityView removeViewAnimated:YES];
}
-(void)requestFailed:(ASIHTTPRequest *)request {
NSLog(#"error==%#",request.error); [DSBezelActivityView removeViewAnimated:YES];
}
I need to save the video in the album i created.
How can i do that?

Answer 1

You can save your video to your saved photos album using "ALAssetsLibrary" like this:
ALAssetsLibrary *library = [[ALAssetsLibrary alloc] init];
NSURL *capturedVideoURL = [NSURL URLWithString:#"/Users/seemtech/Desktop/dd/vvv.m4v"];
if ([library videoAtPathIsCompatibleWithSavedPhotosAlbum:capturedVideoURL]) {
// request to save video in photo roll.
[library writeVideoAtPathToSavedPhotosAlbum:capturedVideoURL completionBlock:^(NSURL *assetURL, NSError *error) {
if (error) {
NSLog(#"error while saving video");
} else{
[self addAssetURL:assetURL toAlbum:#"iphonemaclover"];
}
}];
}
Add that asset to your album
- (void)addAssetURL:(NSURL*)assetURL toAlbum:(NSString*)albumName
{
ALAssetsLibrary *library = [[ALAssetsLibrary alloc] init];
[library enumerateGroupsWithTypes:ALAssetsGroupAlbum usingBlock:^(ALAssetsGroup *group, BOOL *stop) {
if ([albumName compare: [group valueForProperty:ALAssetsGroupPropertyName]]==NSOrderedSame) {
//If album found
[library assetForURL:assetURL resultBlock:^(ALAsset *asset) {
//add asset to album
[group addAsset:asset];
} failureBlock:nil];
}
else {
//if album not found create an album
[library addAssetsGroupAlbumWithName:albumName resultBlock:^(ALAssetsGroup *group) {
[self addAssetURL:assetURL toAlbum:albumName];
} failureBlock:nil];
}
} failureBlock: nil];
}
The only problem with this code is it keeps a copy of video in saved photos album. So find a way to delete an asset from albums. This Link might help.
