Swift: 复制用户在ABPersonViewController中选择的信息到字典
Swift: Copy Information Selected by User in ABPersonViewController to Dictionary
我正在尝试实现 func personViewController(personViewController: ABPersonViewController!,
shouldPerformDefaultActionForPerson person: ABRecord!,
property property: ABPropertyID,
identifier valueIdentifier: ABMultiValueIdentifier) -> Bool 函数，它是 ABPersonViewControllerDelegate 协议的一部分，每当用户单击 ABPersonViewController 中的项目时调用，这样用户选择的任何信息都将被复制到 [String : String] 字典中，这样 属性 名称将成为 属性 值的键：比方说 [..."kABPersonFirstNameProperty" : "Alexander"...]。
我还想避免切换或一长串条件测试 属性 是这个还是那个；我宁愿尽可能一般地处理它——我只尝试两种不同的情况：如果 属性 是单个值或多个值。如果它是一个多值，我想复制所有可用的信息。
例如，如果用户点击地址，结果可能是这样的：[..."kABPersonAddressStreetKey" : "1 Infinite Loop", "kABPersonAddressCityKey" : "Cupertino" , "kABPersonAddressStateKey", "California (or CA?)"...]。
经过数小时搜索 Apple Developer Library 和相关的 SO 问题（我知道这很可悲），这就是我的全部：
func personViewController(personViewController: ABPersonViewController!,
shouldPerformDefaultActionForPerson person: ABRecord!,
property property: ABPropertyID,
identifier valueIdentifier: ABMultiValueIdentifier) -> Bool {
s["kABPersonFirstNameProperty"] = ABRecordCopyValue(person, kABPersonFirstNameProperty) as! String //the name can't actually be selected by the user, but I want to capture it anyway
s["kABPersonLastNameProperty"] = ABRecordCopyValue(person, kABPersonLastNameProperty) as! String
if valueIdentifier == 0 { //property is a single property, not a multivalue property
let record = ABRecordCopyValue(person, property)
s[property as! String!] = record as! String
} else { //property is an ABMultiValue
let multiRecord = ABRecordCopyValue(person, property) as! ABMultiValueRef
s[property as! String] = ABMultiValueGetIndexForIdentifier(multiRecord, valueIdentifier)
}
return false
}
我看得出来少了很多东西——有没有可能把它浓缩成一本字典？

恐怕没有通用的方法可以从 AddressBook 中检索信息，因为有太多不同的集合和 属性 类型。
这是一个在用户点击地址字段时获取 first name、last name 和 address 信息的示例。
假定字典 s 被声明为
var s = Dictionary<String, AnyObject>()
func personViewController(personViewController: ABPersonViewController!, shouldPerformDefaultActionForPerson person: ABRecord!, property: ABPropertyID, identifier: ABMultiValueIdentifier) -> Bool {
addPropertyForKey("FirstName", person : person, property: kABPersonFirstNameProperty)
addPropertyForKey("LastName", person : person, property: kABPersonLastNameProperty)
if (property == kABPersonAddressProperty) {
let multiRecord : ABMultiValueRef = ABRecordCopyValue(person, property).takeUnretainedValue()
let index = ABMultiValueGetIndexForIdentifier(multiRecord, identifier)
let addressRecord :AnyObject = ABMultiValueCopyValueAtIndex(multiRecord, index).takeUnretainedValue()
addValuesFromRecord(addressRecord, forKeys:["Street", "City", "State", "ZIP", "Country", "CountryCode"])
println(s)
}
return false
}
func addPropertyForKey(key : String, person: ABRecord, property : ABPropertyID)
{
let value : AnyObject = ABRecordCopyValue(person, property).takeUnretainedValue()
s[key] = value
}
func addValuesFromRecord(record : AnyObject, forKeys keys : [String])
{
for key in keys {
if let value : AnyObject = record[key] {
s[key] = value
}
}
}
为了尽可能通用，所有值都声明为 AnyObject
以vadian的回答为起点，我编译了以下内容，它将收集并复制用户可以select的几乎所有信息（以及一些用户无法点击的信息） on—名字、姓氏、组织—自动）。
这是一项正在进行的工作，我会在继续添加对更多属性的支持时对其进行更新，但目前它适用于名字、姓氏、电子邮件、phone 号码、地址和一些社交资料。
在某些情况下我不得不使用间接方法：例如，将标签没有指定键的 phone 个数字存储为 kAB_Labels，并且它还没有采用电子邮件地址的标签。
