Question

Scroll down to EDIT 1. This top bit is irrelevant now.

This is my code:

NSMutableDictionary *dictionary = [self.media objectAtIndex:index];
    NSLog(@"dictionary: %@", dictionary);
    NSString *originalImagePath = [dictionary objectForKey:@"OriginalImage"];
    NSLog(@"path: %@", originalImagePath);
    UIImage *originalImage = [UIImage imageWithContentsOfFile:originalImagePath];
    NSLog(@"original image: %@", originalImage);
    return originalImage;

And my NSLog:

dictionary: {
    IsInPhotoLibrary = 1;
    MediaType = 0;
    OriginalImage = "/var/mobile/Applications/5E25F369-9E05-4345-A0A2-381EDB3321B8/Documents/Images/E9904811-B463-4374-BD95-4AD472DC71A6.jpg";
}
path: /var/mobile/Applications/5E25F369-9E05-4345-A0A2-381EDB3321B8/Documents/Images/E9904811-B463-4374-BD95-4AD472DC71A6.jpg
original image: (null)

Any ideas why this might be coming out as null, despite everything appearing to be in place?

EDIT:

This is the code to write the image to file:

+(NSString *)writeImageToFile:(UIImage *)image {
    NSData *fullImageData = UIImageJPEGRepresentation(image, 1.0f);

NSString *path = [NSHomeDirectory() stringByAppendingPathComponent:@"Documents/Images/"];
NSString *name = [NSString stringWithFormat:@"%@.jpg", [JEntry generateUuidString]];
NSString *filePath = [path stringByAppendingPathComponent:name];
[fullImageData writeToFile:filePath atomically:YES];
NSLog(@"original image 2: %@", [UIImage imageWithContentsOfFile:filePath]);
}

This NSLog also comes out as null. So the problem lies here, most likely. Any ideas?

EDIT 2:

So, back-tracing even more now, and I’ve realised that it’s because this fails:

[fullImageData writeToFile:filePath atomically:YES];

You can return a bool on that line, telling if it was successful or not, and it’s returning NO for me. Any ideas why this might be?

EDIT 3:

The image that gets passed in is NULL. Trying to figure out where that’s gone wrong now.

Answer 1

Almost certainly your file does not exist. Modify your code as follows to log if a file exists or not:

NSString *originalImagePath = [dictionary objectForKey:@"OriginalImage"];
NSLog(@"path: %@", originalImagePath);
BOOL fileExists = [[NSFileManager defaultManager] fileExistsAtPath:originalImagePath];
NSLog(@"file exists: %d", fileExists);
