Get image name from UIImage - ios

Question

In one of my project there is a functionality to pick image from Photos. So for that I've used one third party lib named "YangMingShan". The functionality works perfect as per my requirement.
But the problem is that, I want to get the image name picked from the Photos. Whenever I picked single image from photos, it called below method. And it gives me image.
func photoPickerViewController(_ picker: YMSPhotoPickerViewController!, didFinishPicking image: UIImage!) {
}
Can anyone please help me to get the image name from image ?

Answer 1

func photoPickerViewController(_ picker: YMSPhotoPickerViewController!, didFinishPickingImages photoAssets: [PHAsset]!) {
// Remember images you get here is PHAsset array, you need to implement PHImageManager to get UIImage data by yourself
picker.dismiss(animated: true) {
let options = PHImageRequestOptions.init()
options.deliveryMode = .highQualityFormat
options.resizeMode = .exact
options.isSynchronous = true
var imagesWithName:[ImageModel] = []
for asset: PHAsset in photoAssets {
print(asset.originalFilename)
let image = asset.getImage()
let fileName = asset.originalFilename
imagesWithName.append(ImageModel(name: fileName, image: image))
}
print(imagesWithName)
// Assign to Array with images
}
}
the extension of PHAsset to get file name as follows
extension PHAsset {
var primaryResource: PHAssetResource? {
let types: Set<PHAssetResourceType>
switch mediaType {
case .video:
types = [.video, .fullSizeVideo]
case .image:
types = [.photo, .fullSizePhoto]
case .audio:
types = [.audio]
case .unknown:
types = []
#unknown default:
types = []
}
let resources = PHAssetResource.assetResources(for: self)
let resource = resources.first { types.contains($0.type)}
return resource ?? resources.first
}
var originalFilename: String {
guard let result = primaryResource else {
return "file"
}
return result.originalFilename
}
func getImage() -> UIImage {
let manager = PHImageManager.default()
let option = PHImageRequestOptions()
var thumbnail = UIImage()
option.isSynchronous = true
manager.requestImage(for: self,
targetSize: CGSize(width: self.pixelWidth, height: self.pixelHeight),
contentMode: .aspectFit,
options: option,
resultHandler: {(result, info) -> Void in
thumbnail = result!
})
return thumbnail
}
}
and the model
struct ImageModel {
let name:String
let image:UIImage
}
replace the line 77 in Pod -> YangMingSha -> YMSPhotoPicker -> YMSPhotoPickerViewController.h with
- (void)photoPickerViewController:(YMSPhotoPickerViewController *)picker didFinishPickingImage:(UIImage *)image didFinishPickingAssets:(PHAsset *)photoAssets;
then after build it will raise two error for that photoAsset parameter missing in delete function
in YMSPhotoPickerViewController.m replace the error part line 256 with
[self.delegate photoPickerViewController:self
didFinishPickingImage:[self yms_orientationNormalizedImage:image] didFinishPickingAssets:asset];
and in other error also replace the code with
PHAsset *asset = self.currentCollectionItem[#"assets"];
[self.delegate photoPickerViewController:self
didFinishPickingImage:[self yms_orientationNormalizedImage:image] didFinishPickingAssets:asset];
and the singleImage delegate method now should be like this
func photoPickerViewController(_ picker: YMSPhotoPickerViewController!, didFinishPicking image: UIImage!, didFinishPickingAssets photoAssets: PHAsset!) {
let asset = photoAssets.originalFilename
let image = photoAssets.getImage()
print(asset)
picker.dismiss(animated: true)
}
