Я пытаюсь загрузить изображение, выбрав его через UIImagePickerController и загрузив на сервер. Для этого мне нужен фактический локальный путь (URL) изображения. Поскольку я ориентируюсь на iOS 9.0 и выше, я использую Photos Framework.
Я могу получить имя файла, а также URL-адрес из PHAsset. Я также проверяю, присутствует ли файл по этому URL-адресу, но когда я пытаюсь загрузить изображение, я не уверен, является ли это правильным URL-адресом для предоставления php-скрипту на сервере. Для сценария php требуется имя файла, фактическое местоположение на устройстве, а также данные файла.
Вот мой код:
#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());

Я только хочу знать, где я иду не так. Является
Файл: ///var/mobile/Media/PhotoData/CPLAssets/group125/0888AEED-48C6-4E6E-93AB-CE99A6E706AF.JPG
правильный путь к файлу?
