UIImage imageWithContentsOfFile: not working on real device

I'm creating a tableView which contains the images from gallery picked by the user, then I take the selected imagePath to place it on an UIImageView.

To set an iOS gallery image in a UIImageView, I'm using:

NSString *imgPath = @"/var/mobile/Media/DCIM/105APPLE/IMG_5903.JPG";//Hardcoded path just for test, image actually exists on iOS device

self.imgViewContainer.image = [UIImage imageWithContentsOfFile: imgPath];

This code which works on Simulator.

I tested on a real device and I noticed that the UIImageView is empty after execute the above code.

Is there a way to achieve this using a real device?

Due to app sandboxing, your app does not have permission to view the contents of /var/mobile/Media (or really any subdirectory of /var/). Consider the code below:

do {
    let fileList = try FileManager.default.contentsOfDirectory(atPath: "/var/mobile/Media/DCIM/")
} catch {
    print(error)
}

contentsOfDirectory(atPath:) with throw an error with these details:

Error Domain=NSCocoaErrorDomain Code=257 "The file “DCIM” couldn’t be opened because you don’t have permission to view it." UserInfo={NSFilePath=/var/mobile/Media/DCIM/, NSUserStringVariant=(
    Folder
), NSUnderlyingError=0x170045700 {Error Domain=NSPOSIXErrorDomain Code=1 "Operation not permitted"}}

This example is in Swift, but the equivalent Objective-C code would have the same error.

There is no way around this (unless your are using a jailbroken device running your application as the root user). Use UIImagePickerController to ask the user for an image.
