在iPhone模拟器中看起来像是超级简单的东西,代码在实际设备上正常工作我得到recordDoesNotExist错误。基本上我只是从CNContactPickerViewController中选择一个联系人并将其添加到CNGroup
func getGroup(cb:@escaping (CNGroup?)->()){
do{
let groups = try store.groups(matching: nil).filter{$0.name == "someGroup"}
if let group = groups.first{
print("got a group")
return cb(group)
}
let g = CNMutableGroup()
g.name = "someGroup"
let sr = CNSaveRequest()
sr.add(g, toContainerWithIdentifier: nil)
try store.execute(sr)
return getGroup(cb:cb) //try again this might create a indefinate loop if try doesnt stop execution until end of do statement
}catch{
DispatchQueue.main.async {
self.present(Alerter("Error", "encountered an error fetching the group"), animated: true)
return cb(nil)
}
}
}
func contactPicker(_ picker: CNContactPickerViewController, didSelect contact: CNContact) {
getGroup{group in
guard group != nil else {return}
let sr = CNSaveRequest()
sr.add(contact, to:group!)
do{
try self.store.execute(sr)
}catch{
print(error)
}
}
这在模拟器中工作正常,但在我的手机上不起作用,我能够使用标识符查询此联系人,并且联系人在商店中,但是每当我尝试添加到组时,我都会收到错误"保存请求失败,因为它更新了一条不存在或已被删除的记录。"
