从包含字符串数组的对象元素中过滤结构对象

我定义的结构如下:

struct ECUnifiedStructure{

var contactName             : String!
var contactNumber           = [String]()
...
...

init(contact: CNContact , EProfile : Bool) {
    let validTypes = [
        CNLabelPhoneNumberiPhone,
        CNLabelPhoneNumberMobile,
        CNLabelPhoneNumberMain,
        CNLabelHome,
        CNLabelWork
    ]

    var givenName           = contact.givenName + " " + contact.middleName
    let familyName          = contact.familyName
    if (givenName == "" && familyName == "") || givenName == " "{
        givenName           = contact.organizationName
    }

    self.contactName = givenName.capitalized + familyName.capitalized
    self.contactNumber = contact.phoneNumbers.compactMap({ (PhoneNumber) -> String? in
        if let phoneLabel  = PhoneNumber.label , validTypes.contains(phoneLabel){
            return PhoneNumber.value.stringValue.replacingOccurrences(of: " ", with: "").replacingOccurrences(of: "-", with: "")
        }
        return nil
    })
....
....
....
}}

问题陈述:需要根据名称和电话号码过滤ECUnifiedStructure数组(即[ECUnifiedStructure])(检查子字符串和整个字符串)。

当前实现:以下是我已经完成的当前实现。这里的触点和过滤器触点都是[ECUnifiedStructure]。

self.filterContacts = self.contacts.filter {($0.contactName).range(of: textString, options: [ .caseInsensitive, .diacriticInsensitive ]) != nil} + self.contacts.filter {($0.contactNumber.compactMap {$0}.contains(textString))}

实现问题:获取用于按预期过滤联系人姓名的结果,结果包括整个字符串和子字符串,但

  

过滤电话号码时,找不到子字符串的结果 找不到。只有当我们给出完整的电话号码时,结果才会出现。

可能的原因:

self.contacts.filter {($0.contactNumber.compactMap {$0}.contains(textString))}
  

例如:假设联系人= [[姓名:“ David”,电话号码:   [“ 1234567890”,9876543210]],[名称:“希尔顿”,电话号码:   [“ 1011111111”,“ 2222222222”]],[名称:“刘易斯”,电话号码:   [“ 1111111111”,“ 2222222222”]]]

searchString =“ 10”

  

预期结果= [[name:“ David”,phoneNumber:   [“ 1234567890”,9876543210]],[名称:“希尔顿”,电话号码:   [“ 1011111111”,“ 2222222222”]]]

当前结果=空。

请提出一种优雅的方法。如果可以,请指出我做错了什么。预先感谢。

答案 0 :(得分:1)

这将返回电话号码包含“ 10”的所有struct对象

let result = contacts.filter{ $0.phoneNumber.contains(where: { $0.contains("10")}) }

使用原始过滤器代码

self.filterContacts = self.contacts.filter {($0.contactName).range(of: textString, options: [ .caseInsensitive, .diacriticInsensitive ]) != nil} + self.contacts.filter { $0.contactNumber.contains(where: {$0.contains(textString)})}

这是我完整的测试代码

struct ECUnifiedStructure{
    var name          : String!
    var phoneNumber   = [String]()
}

let contacts:[ECUnifiedStructure] = [ECUnifiedStructure(name: "David" , phoneNumber : ["1234567890","9876543210"]), 
     ECUnifiedStructure(name: "Hilton" , phoneNumber : ["1011111111","2222222222"]) , 
     ECUnifiedStructure(name: "lewis" , phoneNumber : ["1111111111","2222222222"])]

let result = contacts.filter{ $0.phoneNumber.contains(where: { $0.contains("10")}) }

for r in result {
    print(r)
}

输出

ECUnifiedStructure(name: Optional("David"), phoneNumber: ["1234567890", "9876543210"])
ECUnifiedStructure(name: Optional("Hilton"), phoneNumber: ["1011111111", "2222222222"])
