我坚持编程的步骤。我希望你能帮助我。
我在文本文件中获得以下行:
#Objekt
Objektnr; 1000000;
Filialname; Dresden;
Filialeemail; email@email.com;
#Baustelle
Anschrift1;;
Anschrift2;Juwelier Schubert;
Strasse;Theresienstrafle 7;
Land;DE;
Ort;TheTown;
PLZ;12345;
....
我具有以下将文件数据带到数组或字典中的功能。在另一个函数中，我将数据保存到本地CoreData-Database。
func startImportTextfile(fileName: String, fileDir: String) -> Bool {
var filePath : String = folderDocuments.stringByAppendingPathComponent(fileDir)
var fileNameWithPath = filePath.stringByAppendingPathComponent(fileName)
var fullImportContent = String(contentsOfFile: fileNameWithPath, encoding: NSUTF8StringEncoding, error: nil)
if(fullImportContent != "")
{
var stringArray = fullImportContent!.componentsSeparatedByString("\n")
var stringArrayCompleteData = Dictionary<String, Array<Any>>()
var arrIndexSection : String = "NoHeader"
for singleRow in stringArray
{
if(singleRow != "")
{
switch singleRow {
case "#Header":
arrIndexSection = singleRow.stringByReplacingOccurrencesOfString("#", withString: "", options: NSStringCompareOptions.LiteralSearch, range: nil)
case "#Objekt":
arrIndexSection = singleRow.stringByReplacingOccurrencesOfString("#", withString: "", options: NSStringCompareOptions.LiteralSearch, range: nil)
case "#Baustelle":
arrIndexSection = singleRow.stringByReplacingOccurrencesOfString("#", withString: "", options: NSStringCompareOptions.LiteralSearch, range: nil)
case "#Auftraggeber":
arrIndexSection = singleRow.stringByReplacingOccurrencesOfString("#", withString: "", options: NSStringCompareOptions.LiteralSearch, range: nil)
case "#Architekt":
arrIndexSection = singleRow.stringByReplacingOccurrencesOfString("#", withString: "", options: NSStringCompareOptions.LiteralSearch, range: nil)
case "#Vermittler":
arrIndexSection = singleRow.stringByReplacingOccurrencesOfString("#", withString: "", options: NSStringCompareOptions.LiteralSearch, range: nil)
case "#Regulierer":
arrIndexSection = singleRow.stringByReplacingOccurrencesOfString("#", withString: "", options: NSStringCompareOptions.LiteralSearch, range: nil)
case "#Versicherung":
arrIndexSection = singleRow.stringByReplacingOccurrencesOfString("#", withString: "", options: NSStringCompareOptions.LiteralSearch, range: nil)
case "#Kontaktstellen":
arrIndexSection = singleRow.stringByReplacingOccurrencesOfString("#", withString: "", options: NSStringCompareOptions.LiteralSearch, range: nil)
case "#Dateien":
arrIndexSection = singleRow.stringByReplacingOccurrencesOfString("#", withString: "", options: NSStringCompareOptions.LiteralSearch, range: nil)
default:
//Here the multiple array would be filled
var arrSingleRow = singleRow.componentsSeparatedByString(";")
if( arrSingleRow.count > 0 )
{
if( arrIndexSection == "Kontaktstellen" )
{
//TODO: Kontaktstellen einlesen
//#Kontaktstellen
//Baustelle;0;348873;;;;0
//Baustelle;0;381263;;Albrecht;0815;0
//Regulierer/SV;0;171979;Josef;Eder;08546/911055;0
println( "Kontaktstellendaten" )
println( singleRow )
}
else if( arrIndexSection == "Dateien" )
{
//TODO: Dateien einlesen
//#Dateien
//11022015090007_BEmail_INNNUE_21102014141534.pdf; 99; Email an asdfasdf@sdf.de
println( "Dateiendaten" )
println( singleRow )
}
else
{
stringArrayCompleteData[arrIndexSection] = [arrSingleRow[0]: arrSingleRow[1]]
}
}
}
}
}
for key in stringArrayCompleteData {
println("Key: \(key)")
}
return true
}
else
{
return false
}
}
目的是我可以像这样打开数据:
println(stringArrayCompleteData["Objekt"].Objektnr)
但是我不知道我该如何声明stringArrayCompleteData。
也许我必须改变这种清白
var stringArrayCompleteData = Dictionary<String, Array<Any>>()
至
var stringArrayCompleteData = Array<String, Dictionary<String, Any>>()
谢谢你的一点帮助
最佳答案
嗨，罗兰(Roland)，我的建议是将文本分成不同的部分，然后将每个部分放入一个结构中。例如，您将定义一个包含3个属性的Objekt结构:objektnr，filialname和filialeemail。
例如，您可以使用根Person结构创建一个结构树。 Person结构体将包含与Objekt结构体实例，Bastille结构体实例等相对应的属性。
这是定义结构的一些示例代码:
struct Person:Printable {
init() {
}
var objektStruct:Objekt?
var baustelleStruct:Baustelle?
var description:String {
get {
let objektStructDescription = objektStruct != nil ? objektStruct!.description : ""
let baustelleStructDescription = baustelleStruct != nil ? baustelleStruct!.description : ""
return "\(objektStructDescription)\n\n\(baustelleStructDescription)"
}
}
}
struct Objekt:Printable {
var objektnr:Int = 0
var filialname:String = ""
var filialeemail:String = ""
init(text:String) {
// Divide the text into an array of lines
let textLinesArray:[String] = text.componentsSeparatedByString("\n")
// Loop through each line and set the corresponding property
for textLine:String in textLinesArray {
// Separate the components of the line at each ";" character
var components:[String] = textLine.componentsSeparatedByString(";")
components = components.map({ (componentString:String) -> String in
return componentString.stringByTrimmingCharactersInSet(NSCharacterSet.whitespaceCharacterSet())
})
// Get the key and value for the line.
let key:String = components.count > 0 ? components[0] : ""
let value:String = components.count > 1 ? components[1] : ""
// Based on the key, set the appropriate property value
switch key {
case "Objektnr":
if let valueAsInt = value.toInt() {
objektnr = valueAsInt
}
case "Filialname":
filialname = value
case "Filialeemail":
filialeemail = value
default:
break
}
}
}
var description:String {
get {
return "*Objekt*\n Objektnr = \(objektnr)\n Filialname = \(filialname)\n Filialeemail = \(filialeemail)"
}
}
}
struct Baustelle:Printable {
var anschrift1:String = ""
var anschrift2:String = ""
var strasse:String = ""
var land:String = ""
var ort:String = ""
var plz:Int = 0
init(text:String) {
// Divide the text into an array of lines
let textLinesArray:[String] = text.componentsSeparatedByString("\n")
// Loop through each line and set the corresponding property
for textLine:String in textLinesArray {
// Separate the components of the line at each ";" character
var components:[String] = textLine.componentsSeparatedByString(";")
components = components.map({ (componentString:String) -> String in
return componentString.stringByTrimmingCharactersInSet(NSCharacterSet.whitespaceCharacterSet())
})
// Get the key and value for the line.
let key:String = components.count > 0 ? components[0] : ""
let value:String = components.count > 1 ? components[1] : ""
// Based on the key, set the appropriate property value
switch key {
case "Anschrift1":
anschrift1 = value
case "Anschrift2":
anschrift2 = value
case "Strasse":
strasse = value
case "Land":
land = value
case "Ort":
ort = value
case "PLZ":
if let valueAsInt = value.toInt() {
plz = valueAsInt
}
default:
break
}
}
}
var description:String {
get {
return "*Baustelle*\n Anschrift1 = \(anschrift1)\n Anschrift2 = \(anschrift2)\n Strasse = \(strasse)\n Land = \(land)\n Ort = \(ort)\n PLZ = \(plz)"
}
}
}
我为Objekt和Baustelle编写了init方法，以便可以提供整个文本部分，并且该结构负责将其解析为不同的属性。
这是一些使用上述结构的示例代码:
let text = String(contentsOfFile: "/Users/markstone/Downloads/textdata.txt")!
// Divide the text at each double newline into multiline sections.
// Eg., the arrayOfTextSections[0] will be the multiline string:
// #Objekt
// Objektnr; 1000000;
// Filialname; Dresden;
// Filialeemail; email@
let arrayOfTextSections = text.componentsSeparatedByString("\n\n")
// Create an empty Person struct instance. We'll fill it in the loop below
var person = Person()
for textSection in arrayOfTextSections {
// For each text section, find out the heading (eg., #Objekt or #Baustelle).
let sectionStringArray = textSection.componentsSeparatedByString("\n")
let sectionHeading = sectionStringArray[0]
switch sectionHeading {
case "#Objekt":
// Create a new instance of the Objekt using the multiline text in this section, and set this instance to the person.objektStruct property.
person.objektStruct = Objekt(text: textSection)
case "#Baustelle":
// Create a new instance of the Baustelle using the multiline text in this section, and set this instance to the person.baustelleStruct property.
person.baustelleStruct = Baustelle(text: textSection)
default:
break
}
}
print(person)
print(person)行显示以下输出:*Objekt*
Objektnr = 0
Filialname = Dresden
Filialeemail = email@email.com
*Baustelle*
Anschrift1 =
Anschrift2 = Juwelier Schubert
Strasse = Theresienstrafle 7
Land = DE
Ort = TheTown
PLZ = 12345
通过这种方法，将结构实例转换为核心数据存储的托管对象非常容易。
