使用联系人框架创建新组，CNErrorDomain Code = 2 [英] create new group with contacts framework, CNErrorDomain Code = 2

问题描述

我尝试使用联系人框架"创建并保存组. 首先，用户授权该应用程序进行联系人访问. 将显示一个视图控制器，并使用 + 按钮向用户显示带有文本字段的警报视图.

i try to create and save a group with the Contacts Framework. First the user authorize the App for contacts access. A viewcontroller is presented and with a + button user shows an alertview with textfield.

用户键入所需的组名，然后单击警报视图的按钮(保存).

The user types the group name he wants and click to button of the alertview (save).

这是保存新组的代码.群组名称可用，但无论如何都无法保存该群组:

This is the code for saving the new group. The group name is available but it is not possible to save this group anyway:

CNContactStore *contactStore = [CNContactStore new];  

[contactStore requestAccessForEntityType:CNEntityTypeContacts completionHandler:^(BOOL granted, NSError *error){
if (granted) {

    CNMutableGroup *newGroup = [CNMutableGroup new];
    CNSaveRequest *saveRequest = [CNSaveRequest new];

    [newGroup setName:groupName];

    //when saving to container with identifier nil, we get this error:
    //Error Domain=CNErrorDomain Code=2 "(null)" UserInfo={CNInvalidRecords=(
    //"<CNMutableGroup: 0x10a059f20: identifier=2F4981B9-8A47-45A4-8841-1FA5A09584A4:ABGroup, name=gghh>"
    [saveRequest addGroup:newGroup toContainerWithIdentifier:nil];
    [contactStore executeSaveRequest:saveRequest error:&error];

    if (error){
        //error saving group
        //NSLog(@"error message: %@",error);
    } else {
        //if no errors, reload tableview
        dispatch_async(dispatch_get_main_queue(), ^{
            [self.tableView reloadData];
        });
    }
}
}];



Error Domain=CNErrorDomain Code=2 "(null)" UserInfo={CNInvalidRecords=(
    "<CNMutableGroup: 0x14fb3e5e0: identifier=8E490585-1223-407E-B353-0D25609B05AB:ABGroup, name=jddjd>"
)}

下一个奇怪的事情是:为什么保存请求试图保存该组
末尾有标识符:ABGroup?

The next strange thing is: why is the save request trying to save this group
with identifier :ABGroup at the end?

错误包含有关CNInvalidRecords的信息.
我仅使用联系人框架.
为什么会这样?

The Error contains a info about CNInvalidRecords.
I am only using the Contacts Framework.
Why is this happening?

有什么解决办法吗?

推荐答案

使用基本相同的代码对我来说效果很好.

It worked fine for me, with essentially the same code.

CNMutableGroup *newGroup = [CNMutableGroup new];
CNSaveRequest *saveRequest = [CNSaveRequest new];
[newGroup setName:self.groupName];
[saveRequest addGroup:newGroup toContainerWithIdentifier:nil];
[contactStore executeSaveRequest:saveRequest error:&error];

并创建了一个新组
