我正在尝试为我的应用添加一些地址簿功能,但在第二次点击“添加到现有”按钮后,我收到此错误消息。

*断言失败 - [ABPersonViewControllerHelper presentPeoplePickerNavigationControllerForAddToContacts:],/ SourceCache / AddressBookUI_Sim / AddressBookUI-1118 / ABPersonViewControllerHelper.m:2574 2011-10-24 20:41:11.960 locato [4576:11603] 由于未捕获的异常'NSInternalInconsistencyException'而终止应用,原因是:'不应该尝试显示多个添加到现有联系人选择器。' 首先抛出调用堆栈: (0x152e052 0x16bfd0a 0x14d6a78 0xefd2db 0x9d674 0x152fe72 0xd0eb8 0xc8141 0xb9e2f 0x60471d 0x604952 0xe8c86d 0x1502966 0x1502407 0x14657c0 0x1464db4 0x1464ccb 0x17eb879 0x17eb93e 0x574a9b 0x22d9 0x2255) 终止称为抛出异常

我有一个viewcontroller和一个navigationcontroller,并在主视图控制器上显示地址簿的'模态'视图。 (或者我没有得到滑动过渡,这个错误。)。我已经覆盖了这些方法:

 @implementation UIViewController (cancelButton)
- (void)peoplePickerNavigationControllerDidCancel:(ABPeoplePickerNavigationController *)peoplePicker;
{
    UIResponder *responder = self;
    while (responder && ![responder isKindOfClass:[mainViewController class]]) {
        responder = [responder nextResponder];
    }

    [(UIViewController *)responder dismissModalViewControllerAnimated:YES];

}
@end

@implementation UINavigationController (modal)
- (void) presentModalViewController:(UIViewController *)screen animated:(BOOL)animated 
{
    UIResponder *responder = self;
    while (responder && ![responder isKindOfClass:[mainViewController class]]) {
        responder = [responder nextResponder];
    }
    if ([screen isKindOfClass:[ABPeoplePickerNavigationController class]]) {
        ABPeoplePickerNavigationController *scr = screen;
        scr.peoplePickerDelegate = self;
       [scr release];
    }
    [(UIViewController *)responder presentModalViewController:screen animated:YES];
}

我希望得到一些关于我做得不对的澄清!

感谢, 大卫

答案 0 :(得分:0)

在再次尝试之前你可以改变两件事:

    在两个while循环之后
  • ,在执行解除或呈现视图控制器之前检查响应者是否为nil

  • 你不能只指定screen.peoplePickerDelegate = self;而不是使用这个scr吗?
