Question

我正在尝试从用户那里获取USERNAME和PASSWORD并将它们放在一个字符串中。

import UIKit

class CustomCell: UITableViewCell, UIPickerViewDataSource, UIPickerViewDelegate {


    @IBOutlet weak var answer: UITextField!

    var delegate: QuestionSelectorCellDelegate?
    var pickOption: [String] = []
    var pickerView:UIPickerView  = UIPickerView()

    override func awakeFromNib() {
        super.awakeFromNib()
        // Initialization code
    }



    @IBAction func editBeginQuestionSelectorCell(sender: UITextField) {
        pickerView = UIPickerView()
        pickerView.delegate = self

        // --- Thats what I added ---
        pickerView.dataSource = self
        let indexOfDefaultElement = 1 // Make sure that an element at this index exists
        pickerView.selectRow(indexOfDefaultElement, inComponent: 0, animated: false)

        sender.inputView = pickerView
    }


    func displayBlock(block: Block){
        if block.answers != nil {
            pickOption = block.answers! // block.answers! = ["blue","red","green"] for example
        }

    }


    func numberOfComponentsInPickerView(pickerView: UIPickerView) -> Int {
        return 1
    }

    func pickerView(pickerView: UIPickerView, numberOfRowsInComponent component: Int) -> Int {
        return pickOption.count
    }

    func pickerView(pickerView: UIPickerView, titleForRow row: Int, forComponent component: Int) -> String? {
        return pickOption[row]
    }

    func pickerView(pickerView: UIPickerView, didSelectRow row: Int, inComponent component: Int) {
        if row < pickOption.count {
            answer.text = pickOption[row]
            delegate?.updateQuestionSelectorCell(self, rep: pickOption[row])
        }
    }
}

这是我的代码：

var id = "1"
var pw = "password"

但它创造了这个结果：

parser = NSXMLParser(contentsOfURL: NSURL(string : "http://blablabla.com/UNAME&PW")!)!

如何将"http://blablabla.com/\id\&\pw\"和id的值放在字符串中？

对于swift中的Concat字符串，您有两个选择：

let completeURL = "http://blablabla.com/\(usernameVar)&\(passwordVar)"

let completeURL = "http://blablabla.com/" + usernameVar + "&" + passwordVar
