no visible #interface for 'UIImagePickerController - xcode

Question

So my code says
no visible #interface for UIImagePicker Controller
I am using a Tab View Controller
My code for my FirstViewController.m is
#import "FirstViewController.h"
#interface FirstViewController () <UIImagePickerControllerDelegate, UINavigationControllerDelegate> {
UIImagePickerController *bailey;
UIImagePickerController *baileys;
UIImage *image;
IBOutlet UIImageView *imageView;
}
- (IBAction)takePhoto;
- (IBAction)chooseExisting;
#end
#implementation FirstViewController
- (IBAction)takePhoto {
bailey = [[UIImagePickerController alloc]init];
bailey.delegate = self;
[bailey setSourceType:UIImagePickerControllerSourceTypeCamera];
[self presentViewController:bailey animated:YES completion:NULL];
}
- (IBAction)chooseExisting {
baileys = [[UIImagePickerController alloc] init];
baileys.delegate = self;
[baileys setSourceType:UIImagePickerControllerSourceTypePhotoLibrary];
[self presentViewController:baileys animated:YES completion:NULL];
}
- (void) imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
image = [info objectForKey:UIImagePickerControllerOriginalImage];
[imageView setImage:image];
[self dismissViewControllerAnimated:YES completion:NULL];
}
- (void) imagePickerControllerDidCancel:(UIImagePickerController *)bailey {
[self dismissViewControllerAnimated:YES completion:NULL];
}
- (IBAction)ShareFB {
if ([SLComposeViewController isAvailableForServiceType:SLServiceTypeFacebook]) {
slComposeViewController = [SLComposeViewController composeViewControllerForServiceType:SLServiceTypeFacebook];
[slComposeViewController addImage:[UIImage imageNamed:#"image"]];
[slComposeViewController addURL:[NSURL URLWithString:#"http://www.agfg.com.au"]];
[self presentViewController:slComposeViewController animated:YES completion:NULL];
//I borrowed these lines of code from http://www.bit.ly/174eqjy
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *appFile = [documentsDirectory stringByAppendingString:#"upload.png"];
NSString *upLoad = [documentsDirectory stringByAppendingString:#"upload.png"];
NSData *myData = [[NSData alloc]initWithContentsOfFile:appFile];
//Here is the line that fails
[bailey addAttachmentData:myData mimeType:#"image/png" fileName:#"upload"];
//Up to here are the borrowed code lines.
}
else {
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"No Facebook Account Detected" message:#"There are no Facebook Accounts Detected. You can configure them in Settings." delegate:nil cancelButtonTitle:#"Dismiss" otherButtonTitles:nil];
[alert show];
}}
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
}
- (void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
#end
And my code for my FirstViewController.h is
#import <UIKit/UIKit.h>
#import <Social/Social.h>
#interface FirstViewController : UIViewController {SLComposeViewController *slComposeViewController;
UIImage *upLoad;}
- (IBAction)ShareFB;
#end
My app is designed to Take a photo and display the photo (and it does that) and then save that image to the local documents folder on the app (which I got from another post) and then specify that image to upload to Facebook (which I have)
All that works except the saving to a local documents.

Answer 1

If you need to store file in documents directory, use like this,
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0]; // Get documents folder
NSString *dataPath = [documentsDirectory stringByAppendingPathComponent:#"Images"];
if (![[NSFileManager defaultManager] fileExistsAtPath:dataPath])
{
[[NSFileManager defaultManager] createDirectoryAtPath:dataPath withIntermediateDirectories:NO attributes:nil error:nil];
}
NSString *imageFilePath = [NSString stringWithFormat:#"%#/%#",dataPath,#"upload.png"];
UIImage *image = [UIImage imageNamed:#"image"]; //Here place your image
NSData *imageData = [NSData dataWithData:UIImagePNGRepresentation(image)];
[imageData writeToFile:imageFilePath atomically:YES];
If you need to attach image in facebook, use this statement,
[slComposeViewController
addAttachmentData:UIImagePNGRepresentation(image, 1) mimeType:#"image/png" fileName:#"upload.png"];

Answer 2

With the help of Karthika, and his facebook upload code, I was typing it in when I realised that I did not need to implement local documents saving.
Facebook let me add the image in without saving it.
Thanks though Karthika, I could not have done it without you.
