In iOS 10 I start to replace asset-library to PhotoKit to manage image picker. But there is an issue.
The specific step is that app needs system camera and user shot a photo after that the delegate method imagePickerController:didFinishPickingMediaWithInfo:
will be called.
Then, here is my code:
UIImage *pickerImage = [[info objectForKey:UIImagePickerControllerOriginalImage] fixOrientation];
PHPhotoLibrary *photoLibrary = [PHPhotoLibrary sharedPhotoLibrary];
__block NSString *localId;
[photoLibrary performChanges:^{
PHAssetChangeRequest *assetChangeRequest = [PHAssetChangeRequest creationRequestForAssetFromImage:pickerImage];
localId = [[assetChangeRequest placeholderForCreatedAsset] localIdentifier];
} completionHandler:^(BOOL success, NSError * _Nullable error) {
if (success) {
// to get localIdentifier and reload collectionView
}
}];
line 1 that fixOrientation
is a custom category that return UIImage
instance.
Only call [PHAssetChangeRequest creationRequestForAssetFromImage:]
method performs fine. However, when I want to fetch newly created photo to use [assetChangeRequest placeholderForCreatedAsset]
, it shows memory leak and app crash.
Above all, any solution to fetch created photo just moment or other methods to solve that by using Photos Framework?
