Ottieni contatto immagine nella rubrica su iOS

Question

Sono nuovo utilizzando la rubrica e vorrei provare a ottenere alcune informazioni per i contatti nel telefono. È possibile ottenere il contatto immagine di tutti i contatti? Questo sarà per iOS4 o superiore.

Grazie in anticipo!

Answer 1

Sì, è completamente possibile, basta chiedere ad ogni persona record di se ha un'immagine:

Vedere la documentazione: http://developer.apple.com/library/ios/#documentation/AddressBook/Reference/ABPersonRef_iPhoneOS/Reference/reference.html#//apple_ref/doc/uid/TP40007210

funzioni rilevanti:

ABPersonHasImageData(person) 
ABPersonCopyImageDataWithFormat(person) 

Il ABPersonCopyImageDataWithFormat restituisce un CFDataRef. Convertire a NSData con questo (ARC) NSData* data = (__bridge_transfer NSData*) cfData;

Un'immagine può quindi essere creata con [UIImage imageWithData:data]

Answer 2

Questo è davvero bello il codice che ho trovato per selezionare tutto l'inaformation contatto e magari utile per l'utente futuro ..

aggiungere quadro AddressBookUI e AddressBook nel progetto

Than nel file h

#import <UIKit/UIKit.h> 
#import <AddressBookUI/AddressBookUI.h> 

@interface ViewController : UIViewController<ABPeoplePickerNavigationControllerDelegate,UIAlertViewDelegate,UITextFieldDelegate,UINavigationControllerDelegate> 
{ 
    NSString * toEmail; 
} 

- (IBAction)getCaontactDetail:(id)sender; 

@end 

E nel file .m

- (IBAction)getCaontactDetail:(id)sender { 
    //open contact book 
    ABPeoplePickerNavigationController *addressBookController = [[ABPeoplePickerNavigationController alloc]init]; 
    addressBookController.peoplePickerDelegate = self; 
    addressBookController.delegate = self; 

    addressBookController.navigationBar.tintColor = [UIColor redColor]; 
    addressBookController.searchDisplayController.searchBar.tintColor = [UIColor redColor]; 
    addressBookController.searchDisplayController.searchBar.backgroundColor = [UIColor blackColor]; 

    if ([self respondsToSelector:@selector(presentViewController:animated:completion:)]){ 
     [self presentViewController:addressBookController animated:YES completion:nil]; 
    } else { 
     [self presentModalViewController:addressBookController animated:YES]; 
    } 

    addressBookController = nil; 
}
