I'm trying to upload an image by picking it via UIImagePickerController and uploading it to the server. For this I need the actual local path (url) of the image. As I'm targeting iOS 9.0 and above, I'm using the Photos Framework.
I'm able to fetch the filename as well as the url from PHAsset . I'm also checking if the file is present at this url, but when I'm trying to upload the image I'm not sure if this is the proper url to supply to a php script on the server. The php script requires file name, the actual location on the device as well the file data.
Here is my code:
#import "ViewController.h"
#import <Photos/Photos.h>
#import <MobileCoreServices/MobileCoreServices.h>
@interface ViewController ()
@end
@implementation ViewController
- (void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
[PHPhotoLibrary requestAuthorization:^(PHAuthorizationStatus status) {
switch (status) {
case PHAuthorizationStatusAuthorized:
NSLog(@"PHAuthorizationStatusAuthorized");
break;
case PHAuthorizationStatusDenied:
NSLog(@"PHAuthorizationStatusDenied");
break;
case PHAuthorizationStatusNotDetermined:
NSLog(@"PHAuthorizationStatusNotDetermined");
break;
case PHAuthorizationStatusRestricted:
NSLog(@"PHAuthorizationStatusRestricted");
break;
}
}];
NSLog(@"%@",NSHomeDirectory());
}

I only wish to know where am I going wrong. Is file:///var/mobile/Media/PhotoData/CPLAssets/group125/0888AEED-48C6-4E6E-93AB-CE99A6E706AF.JPG the proper filepath?
The PHP script only needs an image in the data form and file name and that you want to give the file. It's just to name a file and you can keep anything that makes sense to your system.
There is no need to give a file path as you already giving the image in the binary form. So you should reimplement your uploadImage: method to only receive data and file name.
