我有如下要求,如在基於tabbar的應用程序中顯示ABPeoplePickerNavigationController。我在網上研究了很多,發現沒有有用的答案,但一個here,實現代碼如下所示,將有助於在tabbar中獲取ABPeoplePickerNavigationController,如圖所示。基於Tabbar的應用程序中的ABPeoplePickerNavigationController

第一次截圖是我運行應用程序時的直接結果,第二次截圖是當我再次點擊聯繫人選項卡(奇怪但那是真的)。現在

-(void)awakeFromNib 
{ 
    ABPeoplePickerNavigationController *nav = [[ABPeoplePickerNavigationController alloc] init]; 
    NSMutableArray *newControllers = [NSMutableArray arrayWithArray: [self.tabBarController viewControllers]]; 
    int index = [newControllers indexOfObject: self]; 
    [newControllers replaceObjectAtIndex: index withObject: nav]; 
    [self.tabBarController setViewControllers: newControllers animated: NO]; 
    [nav release]; 
} 

我的問題是,我能夠通過接觸來瀏覽,但不能設置的ABPeoplePickerNavigationController委託。我想重寫以下代理方法

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

-(BOOL)peoplePickerNavigationController: (ABPeoplePickerNavigationController *)peoplePicker shouldContinueAfterSelectingPerson:(ABRecordRef)person 
{ 
} 

我不能設置,因爲我不知道在哪裏設置委託。請幫助我,因爲我的項目在截止日期,所有其他功能都已完成。

歡迎任何竅門。我假設我可以繼承ABPeoplePickerNavigationController並做一些事情,但不知道該怎麼做。

編輯 設置委託後,我收到以下崩潰時,我點擊聯繫人選項卡。

最後我們安下心與服用選擇器控制器應用程序委託並僅通過從tabBarController視圖控制器數組中獲取viewcontroller來設置其委託。

您需要設置的ABPeoplePickerNavigationController的代表已在awakeFromNib創建後。添加此行:

nav.peoplePickerDelegate = self; 

這將您的自定義視圖控制器設置爲人員選取器的代表。你的控制器需要實現ABPeoplePickerNavigationControllerDelegate協議,你需要實現你在問題中列出的兩種方法。

Thax。我實現爲nav.peoplePickerDelegate = self;但我碰到像這個問題的應用程序崩潰http://stackoverflow.com/questions/7068848/ios-devproblem-uimorenavigationcontroller-and-abpeoplepickernavigationcontroller –

如果我不設置委託工作正常,但委託方法不會被調用,因爲它是沒有設置。 –

你有沒有嘗試設置nav.peoplePickerDelegate = self;像這樣:

-(void)awakeFromNib 
{ 
    ABPeoplePickerNavigationController *nav = [[ABPeoplePickerNavigationController alloc] init]; 
    nav.peoplePickerDelegate = self; 
    NSMutableArray *newControllers = [NSMutableArray arrayWithArray: [self.tabBarController viewControllers]]; 
    int index = [newControllers indexOfObject: self]; 
    [newControllers replaceObjectAtIndex: index withObject: nav]; 
    [self.tabBarController setViewControllers: newControllers animated: NO]; 
    [nav release]; 
} 

而在你@interface你可以表明你是ABPeoplePickerNavigationControllerDelegate委託:

@interface MyCustomViewController : UIViewController <ABPeoplePickerNavigationControllerDelegate> { 

    // .... 
}
