Storing the wrong image filepath in Sqlite database. Objective C, iOS

Question

I have a sqlite database in which I can store images and data and then display it in a ViewController to edit.

I don't have a problem with storing the path in my database.

I am having some trouble where when I finish using the camera or photo roll I use the following code with UIImagePickerController. The UIPickerController class saves the image to the directory and the save class saves the image path but renames it.

But the big trouble comes in where I use a similar piece of code to send to my file where I save my stuff in my database.

What this code does because it is only executed after I push save , is it renames the filepath from when I first ended the UIImagePickerController this means I am storing the wrong image path to the database and it shows in the previous entry.

So after I use my camera or photo roll I get the following in my NSLOG:

This is for when I use UIImagePickerController (Which is the path I want to put in my database)

2013-06-06 17:50:48.019 shotplacementguide001[7235:907] photo_1.png - - /var/mobile/Applications/EE759F67-DA8F-4232-BE4F-35D16D047D24/Documents/photo_1.png

And this is for when I push save:

2013-06-06 17:50:53.827 shotplacementguide001[7235:907] photo_2.png - - /var/mobile/Applications/EE759F67-DA8F-4232-BE4F-35D16D047D24/Documents/photo_2.png

This is my code for the UIImagePickerController:

 -(void)imagePickerController:(UIImagePickerController *)picker
didFinishPickingMediaWithInfo:(NSDictionary *)info
{
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSError *error = nil;
NSArray *dirContents = [[NSFileManager defaultManager] contentsOfDirectoryAtPath:documentsDirectory error:&error];
NSString *fileName = [NSString stringWithFormat:@"photo_%i.png", [dirContents count]];
NSString *imagePath = [documentsDirectory stringByAppendingPathComponent:fileName];
// self.presentImageFileName = [NSString stringWithFormat:fileName];
self.presentImageFileName = [NSString stringWithFormat:@"%@", fileName];
NSLog(@"%@ - - %@", self.presentImageFileName,imagePath );


// Then save the image to the Documents directory
NSString *mediaType1 = [info objectForKey:UIImagePickerControllerMediaType];
if ([mediaType1 isEqualToString:@"public.image"]){
    UIImage *editedImage = [info objectForKey:UIImagePickerControllerOriginalImage];
    NSData *webData = UIImagePNGRepresentation(editedImage);
    [webData writeToFile:imagePath atomically:YES];
}

NSString *mediaType = info[UIImagePickerControllerMediaType];

[self dismissViewControllerAnimated:YES completion:nil];

if ([mediaType isEqualToString:(NSString *)kUTTypeImage]) {
    UIImage *image = info[UIImagePickerControllerOriginalImage];

    animalEditImageView.image = image;
    if (_newMedia)
        UIImageWriteToSavedPhotosAlbum(image,
                                       self,
                                       @selector(image:finishedSavingWithError:contextInfo:),
                                       nil);
}
else if ([mediaType isEqualToString:(NSString *)kUTTypeMovie])
{
    // Code here to support video if enabled
}
}

And for when I push save:

-(IBAction) done:(id) sender
{
Customer *customer = [[Customer alloc] init];
    customer.dateTimeZone = self.dateTimeTextField.text;
    customer.species = self.speciesTextField.text;
    customer.gender = self.genderTextField.text;
    customer.location_name = self.locationTextField.text;
    customer.latitude = self.speciesTextField.text;
    customer.longitude = self.speciesTextField.text;
    customer.firearm = self.firearmTextField.text;
    customer.comments = self.commentsTextField.text;

    // Capture the file name of the image
    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    NSString *documentsDirectory = [paths objectAtIndex:0];
    NSString *fileName = addCustomerFileName;
    self.customerToEdit.imagePath = [documentsDirectory stringByAppendingPathComponent:fileName];
    // self.presentImageFileName = [NSString stringWithFormat:fileName];
    self.presentImageFileName = [NSString stringWithFormat:@"%@", fileName];
    NSLog(@"%@ - - %@", self.presentImageFileName,self.customerToEdit.imagePath );
}

How can I change my above code to only take the imagepath that I saved in -(void)imagePickerController:(UIImagePickerController *)picker not to rename it without actually saving the renamed image to the to the directory like I have done it which is wrong.

Because I save the wrong image path so it will display in the previous entry EditViewController.

I am having trouble using customer.imagePath in the UIPickerController class that I have and using info in my save class because of this:

 -(void)imagePickerController:(UIImagePickerController *)picker
didFinishPickingMediaWithInfo:(NSDictionary *)info

Answer 1

I finally coded a solution that just took the filepath from the UIPhotoPickerController and stored it instead of renaming it.

 // Capture the file name of the image
    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    NSString *documentsDirectory = [paths objectAtIndex:0];
    NSString *fileName = addCustomerFileName;
    self.customerToEdit.imagePath = [documentsDirectory stringByAppendingPathComponent:fileName];
    // self.presentImageFileName = [NSString stringWithFormat:fileName];
    self.presentImageFileName = [NSString stringWithFormat:@"%@", fileName];
    NSLog(@"%@ - - %@", self.presentImageFileName,self.customerToEdit.imagePath );

Your problem is caused by the "naming" algorithm, there is no rename there. So first, you get the files count in the documents folder which by your logs seems to be 1 for the first call, you name the image image_1.jpg and you save it into the documents directory after that you simply have 2 files in your documents folder so when you try again to get the image file path your files count from documents folder will be 2 so you get the image_2.jpg file name.

So we identified the issue, now let's fix it. What you should do is save the file path if you can, and send it to the view controller that will add it to the database or you could just simply change the naming algorithm, you could use the current date ([NSDate date]) as the file name and you sort them and get the last image added...or other algorithm.
