iOS7 调用系统通讯录, 点击取消crash

错误: reason: '-[CyAddNewAddressController peoplePickerNavigationControllerDidCancel:]: unrecognized selector sent to instance 0x14f3c0a0’

原因: iOS7中点击取消的方法, 要自己通过代理写

解决办法: 实现代理方法

- (void)peoplePickerNavigationControllerDidCancel:(ABPeoplePickerNavigationController *)peoplePicker { [peoplePicker dismissViewControllerAnimated:YES completion:nil]; }
