How to delete an image from photo library using UIImagePickerController - ios

Question

I am using UIImagePickerController in my application to pick up the image. I need to delete this image synchronously from iOS PhotoLibrary after picking it up in my application.
- (BOOL)createAndInsertNewElementFromDictionary:(NSDictionary*)dict
{
AlbumElement *newElement;
if ([dict[UIImagePickerControllerMediaType]
isEqualToString:(NSString*)kUTTypeMovie])
{
NSURL *mediaUrl = dict[UIImagePickerControllerMediaURL];
newElement = [AlbumElement createElementWithMediaUrl:mediaUrl
inAlbum:_album.name];
}
else if ([dict[UIImagePickerControllerMediaType]
isEqualToString:(NSString*)kUTTypeImage])
{
UIImage *image = [dict[UIImagePickerControllerOriginalImage] copy];
newElement = [AlbumElement createElementWithImage:image
inAlbum:_album.name];
}
if (newElement != nil)
{
[_album.elements insertObject:newElement atIndex:0];
UIImage *icon = [UIImage imageWithContentsOfFile:[newElement iconFullPath]];
[AlbumElement writeImageToFileWithImage:icon
atFullPath:_album.albumIconPath];
}
else
{
NSLog(#"Element was NOT added!");
return NO;
}
return YES;
}

Answer 1

NSURL *url = [dict objectForKey:#"UIImagePickerControllerReferenceURL"] ;
PHPhotoLibrary *library = [PHPhotoLibrary sharedPhotoLibrary];
[library performChanges:^{
// Here assetsURLs is array of url's you want to delete
PHFetchResult *assetsToBeDeleted = [PHAsset fetchAssetsWithALAssetURLs:[NSArray arrayWithObject:url] options:nil];
[PHAssetChangeRequest deleteAssets:assetsToBeDeleted];
} completionHandler:^(BOOL success, NSError *error)
{
// Check error and success here
}];

You can do something like this,
-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary<NSString *,id> *)info{
NSURL *imgURL = info[UIImagePickerControllerReferenceURL];
[[PHPhotoLibrary sharedPhotoLibrary]performChanges:^{
PHAsset *imageAssetTodelete = [PHAsset fetchAssetsWithALAssetURLs:imgURL options:nil];
[PHAssetChangeRequest deleteAssets:imageAssetTodelete];
} completionHandler:^(BOOL success, NSError * _Nullable error) {
if (error) {
NSLog(#"err description : %#",[error localizedDescription]);
}
if (success) {
NSLog(#"image deleted successfully");
}
}];
}
And don't forget to #import Photos; in your class.
Hope this will help :)

I use the same code like #MOHAMMAD ISHAQ but in my case that not work, the picture are not deleted, I have no any error.
Any help or suggestion please ?
PHAsset *asset = nil;
PHFetchOptions *fetchOptions = [[PHFetchOptions alloc] init];
fetchOptions.sortDescriptors = #[[NSSortDescriptor sortDescriptorWithKey:#"creationDate" ascending:YES]];
PHFetchResult *fetchResult = [PHAsset fetchAssetsWithMediaType:PHAssetMediaTypeImage options:fetchOptions];
if (fetchResult != nil && fetchResult.count > 0) {
// get last photo from Photos
asset = [fetchResult lastObject];
}
if (asset) {
PHContentEditingInputRequestOptions *editOptions = [[PHContentEditingInputRequestOptions alloc] init];
[asset requestContentEditingInputWithOptions:editOptions completionHandler:^(PHContentEditingInput *contentEditingInput, NSDictionary *info) {
if (contentEditingInput.fullSizeImageURL) {
//do something with contentEditingInput.fullSizeImageURL
NSLog(#"¨PATH %#",contentEditingInput.fullSizeImageURL);
NSMutableArray *persons = [[NSMutableArray alloc]initWithCapacity:0];
[persons addObject:contentEditingInput.fullSizeImageURL];
NSArray *myArray = [[NSArray alloc]initWithArray:persons];
PHPhotoLibrary *library = [PHPhotoLibrary sharedPhotoLibrary];
[library performChanges:^{
PHFetchResult *assetsToBeDeleted = [PHAsset fetchAssetsWithALAssetURLs:myArray options:nil];
[PHAssetChangeRequest deleteAssets:assetsToBeDeleted];
} completionHandler:^(BOOL success, NSError *error)
{
//do something here
NSLog(#"DELETE IAMGE");
}];
}
}];
Thank
