UIImagePickerController, saveing 2 images to documentsdir with different names - ios

Question

i would like to save 2 images as they get picked to separate names.
i used this guide to make my uiimagepickercontroller : guide
basically it's one uiimagepickercontroller that manages 2 uiimageviews, is it possible to make it save 2 different images with separate names ? or should i try to make uiimagepickercontroller different ?
here's my code, and it not's working for saving.
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *imagePath = [documentsDirectory stringByAppendingPathComponent:#"latest_photo.png"];
//extracting image from the picker and saving it
NSString *mediaType = [info objectForKey:UIImagePickerControllerMediaType];
if ([mediaType isEqualToString:#"public.image"]){
UIImage *editedImage = [info objectForKey:UIImagePickerControllerEditedImage];
NSData *webData = UIImagePNGRepresentation(editedImage);
[webData writeToFile:imagePath atomically:YES];
}
switch (_selectedPhotoType) {
case imageView1Type:
imageView1.image = [info objectForKey:UIImagePickerControllerOriginalImage];
break;
case imageView2Type:
imageView2.image = [info objectForKey:UIImagePickerControllerOriginalImage];
break;
default:
break;
}
[self dismissViewControllerAnimated:YES completion:^{ }];
}

Answer 1

Take a look at this implementation. Is that you need?
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *imagePath = [documentsDirectory stringByAppendingPathComponent:#"latest_photo.png"];
//extracting image from the picker and saving it
NSString *mediaType = [info objectForKey:UIImagePickerControllerMediaType];
UIImage *editedImage = [info objectForKey:UIImagePickerControllerEditedImage];
NSData *webData = UIImagePNGRepresentation(editedImage);
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
switch (_selectedPhotoType) {
case imageView1Type: {
NSString *imagePath = [documentsDirectory stringByAppendingPathComponent:#"latest_photo1.png"];
imageView1.image = [info objectForKey:UIImagePickerControllerOriginalImage];
}
break;
case imageView2Type: {
NSString *imagePath = [documentsDirectory stringByAppendingPathComponent:#"latest_photo2.png"];
imageView2.image = [info objectForKey:UIImagePickerControllerOriginalImage];
}
break;
default:
break;
}
[webData writeToFile:imagePath atomically:YES];
[self dismissViewControllerAnimated:YES completion:^{ }];
}

Answer 2

figured it out with little help from #Heximal
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *imagePath = [documentsDirectory stringByAppendingPathComponent:#"latest_photo.png"];
//extracting image from the picker and saving it
NSString *mediaType = [info objectForKey:UIImagePickerControllerMediaType];
switch (_selectedPhotoType) {
case imageView1Type: {
NSString *imagePath = [documentsDirectory stringByAppendingPathComponent:#"latest_photo1.png"];
imageView1.image = [info objectForKey:UIImagePickerControllerEditedImage];
if ([mediaType isEqualToString:#"public.image"]){
UIImage *editedImage = [info objectForKey:UIImagePickerControllerEditedImage];
NSData *webData = UIImagePNGRepresentation(editedImage);
[webData writeToFile:imagePath atomically:YES];
}
}
break;
case imageView2Type: {
NSString *imagePath = [documentsDirectory stringByAppendingPathComponent:#"latest_photo2.png"];
imageView2.image = [info objectForKey:UIImagePickerControllerEditedImage];
if ([mediaType isEqualToString:#"public.image"]){
UIImage *editedImage = [info objectForKey:UIImagePickerControllerEditedImage];
NSData *webData = UIImagePNGRepresentation(editedImage);
[webData writeToFile:imagePath atomically:YES];
}
}
break;
default:
break;
}
[self dismissViewControllerAnimated:YES completion:^{ }];
}
