otwarcie w iPhone App programowo

Question

Jak otworzyć aparat w iPhone App ... Podobnie jak przy użyciu imagepickerview możemy otworzyć library..how otworzyć aplikację aparatu, dzięki czemu możemy zrobić zdjęcie ..

Answer 1

Musisz użyj UIImagePickerController.

picker.sourceType = UIImagePickerControllerSourceTypeCamera; 

Trzeba wdrożyć metodę imagePickerController:didFinishPickingMediaWithInfo:UIImagePickerControllerDelegate a następnie zapisać UIImage do gdziekolwiek chcesz, bez względu na nazwę pliku ze chcesz, stosując metody NSFileManager.

Answer 2

picker.sourceType = UIImagePickerControllerSourceTypeCamera; 

ten kod wywoła kamerę urządzenia ..

Answer 3

EDIT: 15 marca 2016 - Oto szybka wersja mojej wcześniejszej odpowiedzi, jeśli szukasz wersji objective-c będziesz znajdź to poniżej.

- SWIFT -

pierwsze zgodne z protokołem UIImagePickerControllerDelegate i protokół UINavigationControllerDelegate

class ViewController: UIViewController, UIImagePickerControllerDelegate, UINavigationControllerDelegate 

uruchomić kompletacji obraz

func actionLaunchCamera() 
{ 
    if UIImagePickerController.isSourceTypeAvailable(UIImagePickerControllerSourceType.Camera) 
    { 
     let imagePicker:UIImagePickerController = UIImagePickerController() 
     imagePicker.delegate = self 
     imagePicker.sourceType = UIImagePickerControllerSourceType.Camera 
     imagePicker.allowsEditing = true 

     self.presentViewController(imagePicker, animated: true, completion: nil) 
    } 
    else 
    { 
     let alert:UIAlertController = UIAlertController(title: "Camera Unavailable", message: "Unable to find a camera on this device", preferredStyle: UIAlertControllerStyle.Alert) 
     self.presentViewController(alert, animated: true, completion: nil) 
    } 
} 

wdrożenie metod Delegat protokołu UIImagePickerDelegate

func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : AnyObject]) 
{ 
    // create a filepath with the current date/time as the image name 
    let savePath:String = self.documentsPath()! + "/" + self.presentDateTimeString() + ".png" 

    // try to get our edited image if there is one, as well as the original image 
    let editedImg:UIImage? = info[UIImagePickerControllerEditedImage] as? UIImage 
    let originalImg:UIImage? = info[UIImagePickerControllerOriginalImage] as? UIImage 

    // create our image data with the edited img if we have one, else use the original image 
    let imgData:NSData = editedImg == nil ? UIImagePNGRepresentation(editedImg!)! : UIImagePNGRepresentation(originalImg!)! 

    // write the image data to file 
    imgData.writeToFile(savePath, atomically: true) 

    // dismiss the picker 
    self.dismissViewControllerAnimated(true, completion: nil) 
} 

func imagePickerControllerDidCancel(picker: UIImagePickerController) 
{ 
    // picker cancelled, dismiss picker view controller 
    self.dismissViewControllerAnimated(true, completion: nil) 
} 


// added these methods simply for convenience/completeness 
func documentsPath() ->String? 
{ 
    // fetch our paths 
    let paths = NSSearchPathForDirectoriesInDomains(NSSearchPathDirectory.DocumentDirectory, NSSearchPathDomainMask.UserDomainMask, true) 

    if paths.count > 0 
    { 
     // return our docs directory path if we have one 
     let docsDir = paths[0] 
     return docsDir 
    } 
    return nil 
} 

func presentDateTimeString() ->String 
{ 
    // setup date formatter 
    let dateFormatter:NSDateFormatter = NSDateFormatter() 
    dateFormatter.dateFormat = "dd-MM-yyyy HH:mm:ss" 

    // get current date 
    let now:NSDate = NSDate() 

    // generate date string from now 
    let theDateTime = dateFormatter.stringFromDate(now) 
    return theDateTime 

}

EDYCJA: Aktualizacja, aby sprawdzić, czy kamera jest dostępna przed próbą uruchomienia. Dodano również kod pokazujący, jak zapisać zdjęcie png do folderu dokumentów w obszarze izolowanym aplikacji.

Spróbuj (zakłada się, że używasz ARC).

W pliku .h zgodne z protokołem Delegat:

@interface MyViewController : UIViewController <UINavigationControllerDelegate,UIImagePickerControllerDelegate> 

w pliku .m uruchomić próbnika obrazu (aparat fotograficzny):

-(void)actionLaunchAppCamera 
{ 
    if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera]) 
      { 
       UIImagePickerController *imagePicker = [[UIImagePickerController alloc]init]; 
       imagePicker.delegate = self; 
       imagePicker.sourceType = UIImagePickerControllerSourceTypeCamera; 
       imagePicker.allowsEditing = YES; 

       [self presentModalViewController:imagePicker animated:YES]; 
      }else{ 
       UIAlertView *alert = [[UIAlertView alloc]initWithTitle:@"Camera Unavailable" 
                   message:@"Unable to find a camera on your device." 
                   delegate:nil 
                cancelButtonTitle:@"OK" 
                otherButtonTitles:nil, nil]; 
       [alert show]; 
       alert = nil; 
      } 
} 

następnie wdrożyć protokoły delegat obsłużyć użytkownik anuluje wydarzenie lub zapisuje/edytuje/etc zdjęcie.

-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info 
{ 
    //This creates a filepath with the current date/time as the name to save the image 
    NSString *presentTimeStamp = [Utilities getPresentDateTime]; 
    NSString *fileSavePath = [Utilities documentsPath:presentTimeStamp]; 
    fileSavePath = [fileSavePath stringByAppendingString:@".png"]; 

//This checks to see if the image was edited, if it was it saves the edited version as a .png 
if ([info objectForKey:UIImagePickerControllerEditedImage]) { 
    //save the edited image 
    NSData *imgPngData = UIImagePNGRepresentation([info objectForKey:UIImagePickerControllerEditedImage]); 
    [imgPngData writeToFile:fileSavePath atomically:YES]; 


}else{ 
    //save the original image 
    NSData *imgPngData = UIImagePNGRepresentation([info objectForKey:UIImagePickerControllerOriginalImage]); 
    [imgPngData writeToFile:fileSavePath atomically:YES]; 

} 

[self dismissModalViewControllerAnimated:YES]; 

} 

-(void)imagePickerControllerDidCancel:(UIImagePickerController *)picker 
{ 
    [self dismissModalViewControllerAnimated:YES]; 
} 

również dodawać w EDIT: Oto metody użyte mu klasę Utilities uzyskania ścieżkę dokumentu oraz aktualną datę/czas

+(NSString *)documentsPath:(NSString *)fileName { 
    NSArray *paths = NSSearchPathForDirectoriesInDomains (NSDocumentDirectory, NSUserDomainMask, YES); 
    NSString *documentsDirectory = [paths objectAtIndex:0]; 
    return [documentsDirectory stringByAppendingPathComponent:fileName]; 
} 


+(NSString *)getPresentDateTime{ 

    NSDateFormatter *dateTimeFormat = [[NSDateFormatter alloc] init]; 
    [dateTimeFormat setDateFormat:@"dd-MM-yyyy HH:mm:ss"]; 

    NSDate *now = [[NSDate alloc] init]; 

    NSString *theDateTime = [dateTimeFormat stringFromDate:now]; 

    dateTimeFormat = nil; 
    now = nil; 

    return theDateTime; 
} 

Answer 4

// Otwartej Galerii

UIImagePickerController *imagePickerController = [[UIImagePickerController alloc] init]; 
imagePickerController.sourceType = UIImagePickerControllerSourceTypePhotoLibrary; 
imagePickerController.delegate = self; 
if([[[UIDevice currentDevice] systemVersion] floatValue]>=8.0) 
{ 
    [[NSOperationQueue mainQueue] addOperationWithBlock:^{ 

     [self presentViewController:imagePickerController animated:YES completion:nil]; 
    }]; 
} 
else{ 

    [self presentViewController:imagePickerController animated:YES completion:nil]; 
} 

// Dla wersji otwartej Aparat

Answer 5

Oto zaktualizowana wersja odpowiedzi digitalHound, która działa dla Swift 3.

Działanie funkcji Uruchomienie aparatu:

func actionLaunchCamera() 
{ 
    if UIImagePickerController.isSourceTypeAvailable(UIImagePickerControllerSourceType.camera) 
    { 
     let imagePicker:UIImagePickerController = UIImagePickerController() 
     imagePicker.delegate = self 
     imagePicker.sourceType = UIImagePickerControllerSourceType.camera 
     imagePicker.allowsEditing = true 

     self.present(imagePicker, animated: true, completion: nil) 
    } 
    else 
    { 
     let alert:UIAlertController = UIAlertController(title: "Camera Unavailable", message: "Unable to find a camera on this device", preferredStyle: UIAlertControllerStyle.alert) 
     alert.addAction(UIAlertAction(title: "Dismiss", style: .default, handler: nil)) 
     alert.view.tintColor = UIColor(red:0.37, green:0.66, blue:0.44, alpha:1.0) 
     self.present(alert, animated: true, completion: nil) 
    } 

} 

Funkcje Delegat:

func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) { 
     // create a filepath with the current date/time as the image name 
     let savePath:URL = URL(fileURLWithPath: self.documentsPath()! + "/" + self.presentDateTimeString() + ".png") 
     // try to get our edited image if there is one, as well as the original image 
     let editedImg:UIImage? = info[UIImagePickerControllerEditedImage] as? UIImage 
     let originalImg:UIImage? = info[UIImagePickerControllerOriginalImage] as? UIImage 

     // create our image data with the edited img if we have one, else use the original image 
     let imgData:Data = editedImg == nil ? UIImagePNGRepresentation(editedImg!)! : UIImagePNGRepresentation(originalImg!)! as Data 

     // write the image data to file 
     try! imgData.write(to: savePath, options: []) 

     // dismiss the picker 
     self.dismiss(animated: true, completion: nil) 
    } 

    func imagePickerControllerDidCancel(_ picker: UIImagePickerController) { 
     // picker cancelled, dismiss picker view controller 
     self.dismiss(animated: true, completion: nil) 
    } 


    // added these methods simply for convenience/completeness 
    func documentsPath() ->String? 
    { 
     // fetch our paths 
     let paths = NSSearchPathForDirectoriesInDomains(FileManager.SearchPathDirectory.documentDirectory, FileManager.SearchPathDomainMask.userDomainMask, true) 

     if paths.count > 0 
     { 
      // return our docs directory path if we have one 
      let docsDir = paths[0] 
      return docsDir 
     } 
     return nil 
    } 

    func presentDateTimeString() ->String 
    { 
     // setup date formatter 
     let dateFormatter:DateFormatter = DateFormatter() 
     dateFormatter.dateFormat = "dd-MM-yyyy HH:mm:ss" 

     // get current date 
     let now:Date = Date() 

     // generate date string from now 
     let theDateTime = dateFormatter.string(from: now) 
     return theDateTime 
    } 

To co pracował dla mnie.

Answer 6

Krok 1: Potwierdź UIImagePickerControllerDelegate , UINavigationControllerDelegate

Krok 2: (iOS 10+) Dodaj to jako klucz do pliku Info.plist Key: Bezpieczeństwo - kamera Wykorzystanie Opis
wartość: #Your wiadomość

Krok 3: i to w swoim @IBAction

if UIImagePickerController.isSourceTypeAvailable(.camera) { 
     var imagePicker = UIImagePickerController() 
     imagePicker.delegate = self 
     imagePicker.sourceType = .camera 
     imagePicker.allowsEditing = false 
     self.present(imagePicker, animated: true, completion: nil) 
    }
