For storing in database:::

        NSInteger RandomIndex = arc4random() % 1000; 
        NSString *randomImageName =[NSString stringWithFormat:@"Image%i.png",RandomIndex]; 
        NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
        NSString *documentsDirectory = [paths objectAtIndex:0];
        NSString *savedImagePath = [documentsDirectory stringByAppendingPathComponent:randomImageName];
        if ([[NSFileManager defaultManager] fileExistsAtPath:savedImagePath]) {
            [[NSFileManager defaultManager] removeItemAtPath:savedImagePath error:nil];
            NSLog(@"file removed from path");
        }
        NSLog(@"Saved Image Path : %@",savedImagePath);
         NSData* imageData = UIImagePNGRepresentation (image1 ); 
        [imageData writeToFile:savedImagePath atomically:YES];

         //am is a pointer to my entities class. imageData is just a NSString attribute
        am.imageData = randomImageName;

When you get that image from data base, you can write following code...

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
        NSString *documentsDirectory = [paths objectAtIndex:0];
        NSString *savedImagePath = [documentsDirectory stringByAppendingPathComponent:randomImageName];
NSData *myData = [NSData dataWithContentsOfFile:savedImagePath];
        UIImage *selectedImage = [UIImage imageWithData:myData];

I think it is helpful to you.
