前面我已经对系统PickerView做了简单介绍，pickerView用法很简单，但如果想封装好一个PickerView类就不太容易了，本文是我最近一段时间写完项目后封装的一个PickerView类，支持自定义文字选择、日期选择、地区选择，简单易用，下面我值介绍一下用法： // ViewController.swift // JHPickerView // // Created by hanchen on 16/8/16. // Copyright © 2016年 LiJianhui. All rights reserved. //
import UIKit
class ViewController: UIViewController {
private let onePicker: JHPickerView = { var dataSource = [String]() for i in 0..<20 { dataSource.append("\(i)") } return JHPickerView(aDataSource: dataSource, aTitle: "AlonePicker") }() private let datePicker: JHPickerView = { return JHPickerView(aDatePickerMode: .Date, aTitle: "开始日期") }() private let areaPicker: JHPickerView = { return JHPickerView(anAreaType: .ProvinceCityDistrict, aTitle: "地区选择") }() override func viewDidLoad() { super.viewDidLoad() // Do any additional setup after loading the view, typically from a nib. } @IBAction func onePickerBtnAction(sender: UIButton) { onePicker.show() onePicker.showSelectedRow(3, animated: true) onePicker.didClickDoneForTypeAloneHandler { (selectedRow, result) in print("selectedRow:\(selectedRow)") print("result:\(result)") sender.setTitle(result, forState: .Normal) } onePicker.didClickCancelHandler { print("dismiss") } } @IBAction func datePickerBtnAction(sender: UIButton) { datePicker.show() datePicker.setDate(NSDate(), animated: true) datePicker.didClickDoneForTypeDateWithFormat("yyy-MM-dd") { (selectedDate, dateString) in print("selectedDate:\(selectedDate)") print("dateString:\(dateString)") sender.setTitle(dateString, forState: .Normal) } datePicker.didClickCancelHandler { print("dismiss") } } @IBAction func areaPickerBtnAction(sender: UIButton) { areaPicker.show() areaPicker.didClickDoneForTypeAreaHandler { (province, city, district) in print("province:\(province)") print("city:\(city)") print("district:\(district)") sender.setTitle(province! + city! + district!, forState: .Normal) } areaPicker.didClickCancelHandler { print("dismiss") } }} 代码链接下载代码
