本文介绍了使用iOS 9.0中的CNContactPickerViewController,如何启用/禁用单选或多选?的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧! 问题描述 委托CNContactPickerDelegate具有用于单个和多个选择的方法。但是,当我们呈现视图控制器时,我们如何指定要单选还是多选呢?The delegate CNContactPickerDelegate have methods for single and multiple selections. But how do we specify we want single or multiple selection when we present the view controller?我想我错过了一些可能也引起我在以下内容中描述的问题的东西:设置了CNUI错误选择谓词,但是委托不实现contactPicker:didSelectContact: I guess I miss something that perhaps also causes the problem I have described in: CNUI ERROR Selection predicates are set but the delegate does not implement contactPicker:didSelectContact: 推荐答案您只需实现所需的方法。 You need to implement ONLY the method you need. 如果只需要一个联系人,请实施:If you want only one contact, implement: contactPicker:didSelectContact: contactPicker:didSelectContact:如果要进行多项选择,请实施:If you want multiple selection, implement: contactPicker:didSelectContacts: contactPicker:didSelectContacts:如果要为一个联系人选择一个属性,请实施:If you want select one property for one contact, implemente: contactPicker:didSelectContactProperty: contactPicker:didSelectContactProperty:最后一个,不知道如何工作,看起来像个错误,因为如果实现它,我将获得多个联系人选择UI,但无法选择属性。And the last one, don't know how work, looks like a bug, because if I implement it, I get the multiple contact selection UI, but can't select properties. contactPicker:didSelectContactProperties: contactPicker:didSelectContactProperties:编辑:最后,我从didSelectContactProperties获得了一些数据,该方法需要在predicateForSelectionOfProperty中定义。我认为名称不正确,应该使用didSelectContactsProperties,因为我得到了多个联系人的属性。Finally I got some data from didSelectContactProperties, this method required a definition in predicateForSelectionOfProperty. I think the name is incorrect, should be didSelectContactsProperties, because I got the properties for multiple contacts. 这篇关于使用iOS 9.0中的CNContactPickerViewController,如何启用/禁用单选或多选?的文章就介绍到这了,希望我们推荐的答案对大家有所帮助,也希望大家多多支持! 10-19 05:52
