如何通過調用方法而不是按鈕點擊打開聯繫人

我需要從聯繫人獲取電子郵件ID。

而且我需要在一個方法的單獨類中編寫代碼。要調用此類，將類集成到我的項目中只需調用該方法即可。

這就是我需要的。

爲此我在ownServices中的代碼是這樣的。

-(NSString *)getSelectedNumberFromContatcs { 
    ABPeoplePickerNavigationController *peoplePickerController = [[ABPeoplePickerNavigationController alloc] init]; 

    peoplePickerController.peoplePickerDelegate = self; 
    [self presentModalViewController:peoplePickerController animated:NO]; 
    [peoplePickerController release]; 

    return aNSString; 
} 

- (BOOL)peoplePickerNavigationController:(ABPeoplePickerNavigationController *)peoplePicker 
     shouldContinueAfterSelectingPerson:(ABRecordRef)person { 
    // NSString *name = (NSString *)ABRecordCopyValue(person, kABPersonPhoneProperty); 

    return YES; 
} 

- (BOOL)peoplePickerNavigationController:(ABPeoplePickerNavigationController *)peoplePicker 
     shouldContinueAfterSelectingPerson:(ABRecordRef)person 
           property:(ABPropertyID)property 
           identifier:(ABMultiValueIdentifier)identifier { 

    if (property == kABPersonPhoneProperty) { 
     ABMultiValueRef emails = ABRecordCopyValue(person, property); 
     CFStringRef phonenumberselected = ABMultiValueCopyValueAtIndex(emails, identifier); 
     // CFStringRef emailLabelSelected = ABMultiValueCopyLabelAtIndex(emails, identifier); 
     // CFStringRef emailLabelSelectedLocalized = ABAddressBookCopyLocalizedLabel(ABMultiValueCopyLabelAtIndex(emails, identifier)); 

     aNSString = (NSString *)phonenumberselected; 

     // Return to the main view controller. 
     [ self dismissModalViewControllerAnimated:YES ]; 
     return NO; 
    } 
    return YES ; 
} 

- (void)peoplePickerNavigationControllerDidCancel:(ABPeoplePickerNavigationController *)peoplePicker 
{ 
    [ self dismissModalViewControllerAnimated:YES ]; 

}

我打電話給myclassviewcontroller這樣。

- (void)viewDidLoad { 
    [super viewDidLoad]; 
    ownServices *obj = [[ownServices alloc]init]; 
    [obj getSelectedNumberFromContatcs]; 

    }

但是contatcs viewcontraoller未打開。

但我會像viewconrtroller開了這

-(IBAction)openContacts { 
    ABPeoplePickerNavigationController *peoplePickerController = [[ABPeoplePickerNavigationController alloc] init]; 

    peoplePickerController.peoplePickerDelegate = self; 
    [self presentModalViewController:peoplePickerController animated:NO]; 
    [peoplePickerController release]; 

}

然後接觸一個按鈕動作視圖控制器相同的代碼。

我沒有爲什麼視圖控制器沒有通過調用方法打開。

是否可以這樣做。

任何人都可以幫助我。

謝謝你提前。

因爲你使用的類是從NSObject繼承而不是UIViewController所以[self presentModalViewController：peoplePickerController animated：NO];不管用。此外你在一個錯誤的方式

-(NSString *)getSelectedNumberFromContatcs { 
    ABPeoplePickerNavigationController *peoplePickerController = [[ABPeoplePickerNavigationController alloc] init]; 

    peoplePickerController.peoplePickerDelegate = self; 
    [self presentModalViewController:peoplePickerController animated:NO]; 
    [peoplePickerController release]; 

    return aNSString; 
}

讓我知道你想要做什麼實際寫這種方法嗎？

的可能性，我需要通過調用方法來打開聯繫人，並需要得到選擇email.Code必須在另一個類編寫的this.my子類的UIViewController中繼承只有 – MaheshBabu 2011-06-06 07:17:07

是有任何具體的理由來分離代碼。我可以爲您提供用於提取有電子郵件的聯繫人的代碼。此外，您可以選擇要使用的聯繫人。 – 2011-06-06 08:00:31

是的，我的要求是這樣的 – MaheshBabu 2011-06-06 08:31:52

而不是peoplePickerController.peoplePickerDelegate = self是否有可能使用您的主視圖控制器的參考？

沒有，沒有使用主視圖控制器 – MaheshBabu 2011-06-06 07:05:45
