iOS AddressBookUI - “不应尝试显示多个“添加到现有联系人”人员选择器。”
我正在尝试向我的应用程序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。
* -[ABPersonViewControllerHelper presentPeoplePickerNavigationControllerForAddToContacts:]、/SourceCache/AddressBookUI_Sim/AddressBookUI-1118/ABPersonViewControllerHelper.m:2574 中断言失败 2011-10-24 20:41:11.960 定位[4576:11603] 由于未捕获的异常“NSInternalInconsistencyException”而终止应用程序,原因:“不应尝试显示多个“添加到现有联系人”人员选择器。” 第一个抛出调用堆栈: (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
我有一个视图控制器和一个导航控制器,我在主视图控制器上显示地址簿的“模态”视图。 (否则我无法获得滑动过渡,并且出现此错误。)。我已经重写了这些方法:
@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错了什么的澄清!
谢谢, 大卫
I'm trying add some addressbook functionality to my app, but after tap the second time to the 'Add to existing' button I get this error message.

I have a viewcontroller and a navigationcontroller, and im displaying the addressbook's 'modal' views on the main viewcontroller. (or else im not getting the sliding transition, and this error.). I have overridden these methods:
@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];
}
Im hoping to get some clarification on what im not doing right!
thanks,
David

在再次尝试之前,您可以更改两件事:
在两个
while
循环之后,在执行关闭或呈现视图控制器之前检查响应者是否为nil
你不能只分配
screen.peoplePickerDelegate = self;
代码>而不是使用这个scr?Two things you could change before trying again:
after both
while
loops, check that responder is notnil
before doing dismiss or present a viewcontrollercan't you just assign
screen.peoplePickerDelegate = self;
instead of using this scr?
