iOS7 - ABPersonViewController,编辑模式

Question

Apple提供了一个很好的综合小例子,"QuickContacts"(developer.apple.com/library/IOs/samplecode/QuickContacts/Introduction/Intro.html),概述了通讯簿UI框架的基本用法. - 可下载的源代码按照描述工作(一旦将名为"Appleseed"的人添加到地址簿中,或者将第246行(QuickContactsViewController.m)中的人名更改为地址簿中已存在的内容).

问题: 我们如何修改功能-(void)showPersonViewController函数ABPersonViewController "picker",使其在打开时(在被推送到navigationController的堆栈之后)已经处于编辑模式(具有可见的"完成"editButton).

在"7"之前的iOS版本中,只需插入例如picker.editing = YES;在将选择器推到导航堆栈之前,以便在打开时看到它(在下面的代码中看到编辑模式),这是一个直接的问题.

在iOS7中,这不再起作用了.

这是iOS7中的一个错误,如果是这样,是否有一个简单的解决方法(而不是例如逆向工程ABPersonViewController类)？ - 或者它需要以不同的方式编码,这些天？

期待您的评论.

-(void)showPersonViewController
{
    // Search for the person named "Appleseed" in the address book
    NSArray *people = (NSArray *)CFBridgingRelease(ABAddressBookCopyPeopleWithName(self.addressBook, CFSTR("Appleseed")));
    // Display "Appleseed" information if found in the address book 
    if ((people != nil) && [people count])
    {
        ABRecordRef person = (__bridge ABRecordRef)[people objectAtIndex:0];
        ABPersonViewController *picker = [[ABPersonViewController alloc] init];
        picker.personViewDelegate = self;
        picker.displayedPerson = person;
       // Allow users to edit the person’s information
       picker.allowsEditing = YES;

       picker.editing = YES;   // in iOS6 this works, in iOS7 it does not

       [self.navigationController pushViewController:picker animated:YES];
    }   
    ...
    ...
}

您可以使用ABNewPersonViewController而不是ABPersonViewController,下面是代码:

ABNewPersonViewController *picker = [[[ABNewPersonViewController alloc] init] autorelease];
picker.newPersonViewDelegate = self;
picker.displayedPerson = person;
picker.navigationItem.title=@"edit contact";

[self.navigationController pushViewController:picker animated:YES];
