[英]IOS 8 - ABPeoplePickerNavigationController - Cancel delegate method works, others do not
I've encountered a strange problem in my IOS 8 people picker delegate code. 我在IOS 8人员选择器委托代码中遇到了一个奇怪的问题。 Only the
只有
- (void)peoplePickerNavigationControllerDidCancel:(ABPeoplePickerNavigationController *)peoplePicker;
{
[self dismissViewControllerAnimated:YES completion:NULL];
}
method is being called. 方法被调用。 I have reviewed other questions and have made the important IOS 8 delegate method changes for selecting a contact by calling the old IOS 7 method
我已经审查了其他问题,并通过调用旧的IOS 7方法对选择联系人的IOS 8委托方法进行了重要更改。
- (void)peoplePickerNavigationController:(ABPeoplePickerNavigationController *)peoplePicker didSelectPerson:(ABRecordRef)person property:(ABPropertyID)property identifier: (ABMultiValueIdentifier)identifier {
[self peoplePickerNavigationController:peoplePicker shouldContinueAfterSelectingPerson:person property:property identifier:identifier];
}
but it is never called. 但它从未被调用。
I am setting the delegate in the calling viewcontroller didLoad, 我在调用viewcontroller didLoad中设置委托,
and it works perfectly in ios 7. This is a storyboard application. 而且它在ios 7中完美运行。这是一个故事板应用程序。
I saw the same question asked in a comment here: ABPeoplePickerNavigationController changes with iOS8? 我在这里的评论中看到了相同的问题: ABPeoplePickerNavigationController是否随iOS8更改?
but never found an answer. 但从未找到答案。 Obviously a mistake somewhere on my part, but I can't find it.
显然我的某个地方有一个错误,但我找不到它。
UPDATE: As requested, here is how I set the delegate: 更新:根据要求,这是我设置委托的方式:
self.picker = [[ABPeoplePickerNavigationController alloc] init];
self.picker.peoplePickerDelegate = self;
And, in @interface: 并且,在@interface中:
@interface TreatmentsAddEntryTVC : UITableViewController<UITextViewDelegate,ABPeoplePickerNavigationControllerDelegate>
Try using this delegate method instead and see if it hits: 尝试改用此委托方法,看看是否成功:
- (void)peoplePickerNavigationController:(ABPeoplePickerNavigationController*)peoplePicker didSelectPerson:(ABRecordRef)person;
{
// yes the below line is deprecated as of iOS 8
[self peoplePickerNavigationController:peoplePicker shouldContinueAfterSelectingPerson:person];
}
I hate to answer my own question, especially when the answer makes no sense, but moving: 我讨厌回答我自己的问题,尤其是当答案没有任何意义,只是动容的时候:
self.picker = [[ABPeoplePickerNavigationController alloc] init];
self.picker.peoplePickerDelegate = self;
from didLoad to the method where I actually want to display the picker fixed the problem. 从didLoad到我实际要显示选择器的方法,可以解决此问题。 I have seen at least one other question on SO where this behavior was noted and discussed:
我在SO上至少看到了另一个问题,该行为在何处得到记录和讨论:
For a project with iOS 8.1, I replaced this method 对于使用iOS 8.1的项目,我替换了此方法
-(BOOL)peoplePickerNavigationController:(ABPeoplePickerNavigationController *)peoplePicker shouldContinueAfterSelectingPerson:(ABRecordRef)person{
}
with this 有了这个
-(void)peoplePickerNavigationController:(ABPeoplePickerNavigationController*)peoplePicker didSelectPerson:(ABRecordRef)person{
}
And new method did hit when I selected a contact. 当我选择一个联系人时,新方法就成功了。
