Loading UIImage from Directory no longer working - ios

Question

For the past 5 or 6 months i have been saving images to a Photos folder in which i created within the documents directory on the users device. The photos would then be loaded into an imageView when the user entered a specific screen, until recently this has been working perfectly.
Now the images no longer show in the image view and when using the URL to print out the image width and height, the values are zero even though the URL has not changed.
I am using the following code to display the image within the image view.
outputImageView = [[UIImageView alloc] init];
[outputImageView setFrame:originalImageViewSize];
outputImageView.image = [UIImage imageWithData:[NSData dataWithContentsOfFile:photoURL]];
NSLog(#"width %f, height %f", outputImageView.image.size.width, outputImageView.image.size.height);
the photoURL is as follows: /Users/fernandosantos/Library/Developer/CoreSimulator/Devices/6F3FCE2A-F7F9-4F77-B66D-3DA2A25BE166/data/Containers/Data/Application/C3867EFA-6AA8-4B71-A856-DCF7F83DEFF0/Documents/AUDIBURY/Photos/COMMTRCIAL-CSRSignature--2014-10-13 10-49-16.jpg

In iOS8 the application documents directory dynamically changes its name on every running. You have to use the following method from Appdelegate in order to get the current documents directory path:
// Returns the URL to the application's Documents directory.
- (NSURL *)applicationDocumentsDirectory
{
return [[[NSFileManager defaultManager] URLsForDirectory:NSDocumentDirectory inDomains:NSUserDomainMask] lastObject];
}
You should only save the relative path of the file, not the full path. This method also works on iOS7.
You can use the iOS simulator and check that the full path actually doesn't exist.

Thanks to everyone that replied with a suggestion.
I combined what everyone had suggested and came up with this solution which works for me.
//get the documents directory, in iOS 8 this is now dynamic everytime you run the app.
NSString *documentsDirectory = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0];
//Create the CurrentPhotoURL by using the current documents directory and the appending the photo name which
//was created when saving the image originally.
NSString *currentPhotoURL = [[documentsDirectory stringByAppendingString:#"/"] stringByAppendingString:photoName];
Since i had created a new a folder within the documents directory called Photos, the photoName variable holds the name of the Photos folder followed by the name of the image when it was originally saved.
I then append the photoName variable to the current documents directory to get the full directory path for that photo.
This may not be the best solution but its what i came up with and it works.
If anyone else needs further information then please contact me.
