iOS：ABPeoplePickerNavigationController系統通訊錄使用

標籤：

　　昨天因項目需求要訪問系統通訊錄擷取電話號碼，於是乎從一無所知，開始倒騰，倒騰了一下午，總算了弄好了。寫這邊部落格是為了記錄一下，自己下一次弄的時候就別在出錯了。同時，有和我一樣的菜鳥能夠避免走一下彎路。

　　好了，言歸正傳，要訪問系統的通訊錄，首先需要添加AddressBook.framework和AddressBookUI.framework兩個架構到你工程中build phase的"Link Binary With Libraries"之下，然後就可以開始了。

　　首先我們需要建立一個控制器：ViewController，在.h檔案中匯入標頭檔：<AddressBook/AddressBook.h>、 <AddressBookUI/AddressBookUI.h>，

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

然後在控制器實現ABPeoplePickerNavigationControllerDelegate, UINavigationControllerDelegate協議

@interface ViewController ()<ABPeoplePickerNavigationControllerDelegate, UINavigationControllerDelegate>

在viewDidAppear方法中建立ABPeoplePickerNavigationController，同時設定viewController作為委派物件

- (void)viewDidAppear:(BOOL)animated{    [super viewDidAppear:animated];    ABPeoplePickerNavigationController *pNC = [[ABPeoplePickerNavigationController alloc] init];    pNC.peoplePickerDelegate = self;    [self presentViewController:pNC animated:YES completion:nil];}

 接下來需要實現ABPeoplePickerNavigationControllerDelegate協議

#pragma mark - ABPeoplePickerNavigationControllerDelegate- (void)peoplePickerNavigationController:(ABPeoplePickerNavigationController *)peoplePicker didSelectPerson:(ABRecordRef)person property:(ABPropertyID)property identifier:(ABMultiValueIdentifier)identifier {        ABMultiValueRef phone = ABRecordCopyValue(person, kABPersonPhoneProperty);        long index = ABMultiValueGetIndexForIdentifier(phone,identifier);        NSString *phoneNO = (__bridge NSString *)ABMultiValueCopyValueAtIndex(phone, index);    phoneNO = [phoneNO stringByReplacingOccurrencesOfString:@"-" withString:@""];    NSLog(@"%@", phoneNO);    if (phone && phoneNO.length == 11) {        [peoplePicker dismissViewControllerAnimated:YES completion:nil];        return;    }else{        UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"錯誤提示" message:@"請選擇正確手機號" delegate:self cancelButtonTitle:@"確定" otherButtonTitles:nil];        [alertView show];    }}- (void)peoplePickerNavigationController:(ABPeoplePickerNavigationController*)peoplePicker didSelectPerson:(ABRecordRef)person NS_AVAILABLE_IOS(8_0){    ABPersonViewController *personViewController = [[ABPersonViewController alloc] init];    personViewController.displayedPerson = person;        [peoplePicker pushViewController:personViewController animated:YES];        }- (void)peoplePickerNavigationControllerDidCancel:(ABPeoplePickerNavigationController *)peoplePicker{    [peoplePicker dismissViewControllerAnimated:YES completion:nil];}- (BOOL)peoplePickerNavigationController:(ABPeoplePickerNavigationController *)peoplePicker shouldContinueAfterSelectingPerson:(ABRecordRef)person NS_DEPRECATED_IOS(2_0, 8_0){    return YES;}- (BOOL)peoplePickerNavigationController:(ABPeoplePickerNavigationController *)peoplePicker shouldContinueAfterSelectingPerson:(ABRecordRef)person property:(ABPropertyID)property identifier:(ABMultiValueIdentifier)identifier NS_DEPRECATED_IOS(2_0, 8_0){    ABMultiValueRef phone = ABRecordCopyValue(person, kABPersonPhoneProperty);        long index = ABMultiValueGetIndexForIdentifier(phone,identifier);        NSString *phoneNO = (__bridge NSString *)ABMultiValueCopyValueAtIndex(phone, index);    phoneNO = [phoneNO stringByReplacingOccurrencesOfString:@"-" withString:@""];    NSLog(@"%@", phoneNO);    if (phone && phoneNO.length == 11) {        [peoplePicker dismissViewControllerAnimated:YES completion:nil];        return NO;    }else{        UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"錯誤提示" message:@"請選擇正確手機號" delegate:self cancelButtonTitle:@"確定" otherButtonTitles:nil];        [alertView show];    }    return YES;}@end

到這裡本以為大功告成，的確在iOS7是沒有任何問題，但是iOS8出現了坑爹的問題，就是選擇連絡人後

ABPeoplePickerNavigationController會自動dismiss掉，這個問題可坑壞我了。問了Google和度娘，在stackvoerflow找到了類似的問題，但是都沒有得到解決，在覺得沒有辦法的時候，又開始看ABPeoplePickerNavigationController.h的標頭檔，發現了

predicateForSelectionOfPerson屬性，於是乎在viewDidAppear方法中加入如下代碼：

 if([[UIDevice currentDevice].systemVersion floatValue] >= 8.0){        pNC.predicateForSelectionOfPerson = [NSPredicate predicateWithValue:false];    }

運行程式，大功告成。
