添加卡片信息
-
点击头部两个按钮,从相册分别添加正反照片
iOS8之后,使用UIImagePickerController调取相册的时候会崩溃,需要设置权限
原因是我们需要在info.plist文件中添加权限
Privacy - Photo Library Usage Description
是否允许访问相册
Privacy - Camera Usage Description
是否允许访问相机
- 下面是代码部分
isFront控制时正面照片还是反面照片
isFront = btn.tag == 0 ? true : false
//弹框提示如何选择图片
let alertController = UIAlertController(title: btn.tag == 0 ? "正面图片" : "背面图片", message: nil, preferredStyle: .actionSheet)
let cancelAction = UIAlertAction(title: "取消", style: .cancel, handler:
{
(UIAlertAction) -> Void in
print("你点击了取消")
})
let okAction = UIAlertAction(title: "从相册中选择照片", style: .default, handler:
{
(UIAlertAction) -> Void in
print("点击从相册中选择")
let imagePicker = UIImagePickerController()
imagePicker.delegate = self
imagePicker.allowsEditing = true
imagePicker.sourceType = UIImagePickerControllerSourceType.photoLibrary
self.present(imagePicker, animated: true, completion: nil)
})
let okAction1 = UIAlertAction(title: "拍照", style: .default, handler:
{
(UIAlertAction) -> Void in
if UIImagePickerController.isSourceTypeAvailable(.camera)
{
print("拍照可用")
let imagePicker = UIImagePickerController()
imagePicker.delegate = self
imagePicker.allowsEditing = true
imagePicker.sourceType = UIImagePickerControllerSourceType.camera
self.present(imagePicker, animated: true, completion: nil)
}
else
{
print("拍照不可用")
}
})
alertController.addAction(cancelAction)
alertController.addAction(okAction)
alertController.addAction(okAction1)
self.present(alertController, animated: true, completion: nil)
- 要想实现相册选择,必须同时实现UIImagePickerControllerDelegate,UINavigationControllerDelegate两种协议
###在代理中实现,将相册中选中的图片添加至tableView的头部按钮上
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any])
{
//在相册中选择完照片后的回调
picker.dismiss(animated: true, completion: nil)
let imageStr : UIImage = info[UIImagePickerControllerEditedImage] as! UIImage
//显示
if isFront
{
frontBtn.setImage(imageStr, for: UIControlState.normal)
}
else
{
backBtn.setImage(imageStr, for: UIControlState.normal)
}
}
- 点击保存时,检查是否均已输入,若没有则弹框提示,若全部输入则跳出
###判断三个textField
//1.在tableView中记录textField
override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell
{
cell.inputTextField.tag = indexPath.row
return cell;
}
//2.viewDidLoad中注册消息监听
NotificationCenter.default.addObserver(self, selector: #selector(notificationResponse(notification:)), name: NSNotification.Name.UITextFieldTextDidChange, object: nil)
//3.实现实时监听,将textField的值赋值给变量
func notificationResponse(notification: NSNotification)
{
let textField : UITextField = notification.object as! UITextField
if textField.tag == 0
{
memberName = textField.text!
}
else if textField.tag == 1
{
memberNum = textField.text!
}
else
{
memberPassWord = textField.text!
}
}
//4.点击保存按钮的时候,判断变量是否有值
if (memberName.lengthOfBytes(using: String.Encoding.utf8) == 0 ||
memberNum.lengthOfBytes(using: String.Encoding.utf8) == 0 ||
memberPassWord.lengthOfBytes(using: String.Encoding.utf8) == 0)
{
ToastView.instance.showToast(content: "输入不全", duration: 1.5)
}
else
{
print("保存")
}
###判断正反面照片
###照片存本地文件:在documentDirectory下新建"/Documents/Member"的路径,将照片保存在文件中,,均保存在Member文件夹下,并且没张图片以当前时间戳命名
###点击保存时,判断正反面照片是否有值,将当前时间戳.jpg赋值给正反面照片的变量,判断此变量即可
###Tools工具类
getDocumentsMemberFile方法返回在documentDirectory下新建"/Documents/Member"的路径
getTimeSP返回当前时间戳
//MAARK: - 获取Documents下的路径
/*
*在iOS8之前，我们获取到沙盒中的document、cache、tmp之后，下一次模拟器或真机无论怎样重启，这具体的路径是固定的了
在iOS8之后，苹果可能考虑到安全因素，应用每一次重启，沙盒路径都动态的发生了变化,但是并不代表你原来沙盒路径中的数据发生了变化；同时，也并不代表路径会越来越多
1>苹果会把你上一个路径中的数据转移到你新的路径中。
2>你上一个路径也会被苹果毫无保留的删除，只保留最新的路径
*/
public func getDocumentsMemberFile() -> String
{
//Documents下创建或找到文件
let rootPath = NSSearchPathForDirectoriesInDomains(.documentDirectory,.userDomainMask, true)[0] as String
let filePath:String = rootPath + "/Documents/Member"
return filePath
}
//MARK: - 获取当前时间戳
public func getTimeSP() -> Int
{
let now = Date()
let timeInterval:TimeInterval = now.timeIntervalSince1970
let timeStamp = Int(timeInterval)
return timeStamp
}
###在相册选择照片的回调代理中,将已保存在本地文件的图片的最后名字(时间戳)赋值给变量
//MARK: - UIImagePickerControllerDelegate
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any])
{
//在相册中选择完照片后的回调
picker.dismiss(animated: true, completion: nil)
let imageStr : UIImage = info[UIImagePickerControllerEditedImage] as! UIImage
//将图片存入文件
let filePath = Tools().getDocumentsMemberFile()
let exist = FileManager.default.fileExists(atPath: filePath)
if !exist
{
try! FileManager.default.createDirectory(atPath: filePath,
withIntermediateDirectories: true, attributes: nil)
}
//将图片保存在文件中
let imagePath = "\(filePath)/\(Tools().getTimeSP()).jpg"
let imageData = UIImageJPEGRepresentation(imageStr, 1.0)
FileManager.default.createFile(atPath: imagePath, contents: imageData, attributes: nil)
//保存相对路径
let imageNSURL:NSURL = NSURL.init(fileURLWithPath: imagePath)
let imageLastPath = imageNSURL.lastPathComponent!
//显示
if isFront
{
frontBtn.setImage(imageStr, for: UIControlState.normal)
frontPhoto = imageLastPath
}
else
{
backBtn.setImage(imageStr, for: UIControlState.normal)
backPhoto = imageLastPath
}
}
###在点击保存按钮时,判断正反照片的变量是否有值即可
- 若本次卡片信息全部输入,则保存本地
参考:
http://www.jianshu.com/writer#/notebooks/11959695/notes/12740387/preview
###先将本次信息保存字典
var dic = [String:Any]()
dic["frontPhoto"] = frontPhoto
dic["backPhoto"] = backPhoto
dic["memberName"] = memberName
dic["memberNum"] = memberNum
dic["memberPassWord"] = memberPassWord
###声明可变数组memberList,如果本地有memberList的内容,则将它取出来赋值给一个不可变数组,再将不可变数组内容for循环添加至memberList
let memberList : NSMutableArray = []
if UserDefaults.standard.value(forKey: "memberList") != nil
{
let array = UserDefaults.standard.value(forKey: "memberList") as! NSArray
memberList.removeAllObjects()
let num = array.count
for i in 0..<num
{
memberList.add(array[i])
}
}
###如果这个界面时新增卡片页面,则memberList直接添加dic即可,但如果是编辑页面,则需要移除原本的信息,再将新修改的信息保存
if itemDic.count > 0
{
let index = memberList.index(of: itemDic)
memberList.remove(itemDic)
memberList.insert(dic, at: index)
}
else
{
memberList.add(dic)
}
###再将memberList赋值给不可变数组,方便存入UserDefaults保存
let array = memberList
UserDefaults.standard.set(array, forKey: "memberList")
//返回上一页
navigationController?.popViewController(animated: true)
重新编辑卡片信息
是编辑还是新增,是靠itemDic来控制的
//下面是进来编辑的
var itemDic = [String:String]()
如果进页面时itemDic已经被赋值,证明是编辑
###tableView的代理cellForRowAt中,如果itemDic有内容,则显示itemDic内容
if itemDic.count > 0
{
if indexPath.row == 0
{
cell.inputTextField.text = itemDic["memberName"]
memberName = itemDic["memberName"]!
}
else if indexPath.row == 1
{
cell.inputTextField.text = itemDic["memberNum"]
memberNum = itemDic["memberNum"]!
}
else
{
cell.inputTextField.text = itemDic["memberPassWord"]
memberPassWord = itemDic["memberPassWord"]!
}
}
###tableView的头部显示代理viewForHeaderInSection中,如果itemDic有内容,则显示itemDic内容,此时需要拼接上"rootPath + "/Documents/Member""的路径
if itemDic.count > 0
{
let frontImagePath = "\(Tools().getDocumentsMemberFile())/\((itemDic["frontPhoto"])!)"
frontBtn.setImage(UIImage(named:frontImagePath), for: UIControlState.normal)
let backImagePath = "\(Tools().getDocumentsMemberFile())/\((itemDic["backPhoto"])!)"
backBtn.setImage(UIImage(named:backImagePath), for: UIControlState.normal)
frontPhoto = itemDic["frontPhoto"]!
backPhoto = itemDic["backPhoto"]!
}
###保存的时候,如果itemDic有内容,则
if itemDic.count > 0
{
let index = memberList.index(of: itemDic)
memberList.remove(itemDic)
memberList.insert(dic, at: index)
}
卡片列表
- tableView的行数由dataMutableArray的长度决定,但如果dataMutableArray长度为0,则显示背景图
###背景图
//MARK: - 懒加载
private lazy var tvBackgroundView: UIView =
{
let view = UIView()
view.backgroundColor = UIColor.white
let btn = UIButton()
btn.frame = CGRect(x: ScreenWidth / 2 - 100, y: ScreenHeight / 2 - 25, width: 200, height: 50)
btn.setTitle("点击添加第一张银行卡", for: UIControlState.normal)
btn.setTitleColor(UIColor.darkGray, for: UIControlState.normal)
btn.layer.borderColor = UIColor.hexStringToColor(hexString: ColorOfWaveBlueColor).cgColor
btn.layer.borderWidth = 2
btn.layer.cornerRadius = 8
btn.layer.masksToBounds = true
btn.addTarget(self, action:#selector(addMemberCardButtonAction), for: UIControlEvents.touchUpInside)
view.addSubview(btn)
return view
}()
###每次进入页面的时候均判断数组长度
override func viewWillAppear(_ animated: Bool)
{
super.viewWillAppear(true)
print("保存本地的是\(String(describing: UserDefaults.standard.value(forKey: "memberList")))")
//初始化,没有nil判空会崩溃
if UserDefaults.standard.value(forKey: "memberList") != nil
{
let array = UserDefaults.standard.value(forKey: "memberList") as! NSArray
dataMutableArray.removeAllObjects()
let num = array.count
for i in 0..<num
{
dataMutableArray.add(array[i])
}
}
if dataMutableArray.count == 0
{
tableView?.backgroundView = tvBackgroundView
}
else
{
tableView?.backgroundView = nil
}
tableView.reloadData()
}
###显示tableView内容
override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell
{
let identifier = "identtifier";
let cell = memberCardCommonCell(style: UITableViewCellStyle.subtitle, reuseIdentifier: identifier)
cell.accessoryType=UITableViewCellAccessoryType.disclosureIndicator
let item = dataMutableArray[indexPath.row] as! NSDictionary
//因为字典里存的是绝对路径,需要再拼上相对路径
let imagePath = "\(Tools().getDocumentsMemberFile())/\((item["frontPhoto"] as? String)!)"
cell.frontImageView.image = UIImage(named:imagePath)
cell.nameLabel.text = item["memberName"] as? String
cell.numLabel.text = item["memberNum"] as? String
return cell
}
- 编辑
###点击编辑按钮进入编辑状态
func editMemberCardButtonAction()
{
if tableView.isEditing
{
tableView.isEditing = false
}
else
{
tableView.isEditing = true
}
}
###左滑删除
//左滑删除
override func tableView(_ tableView: UITableView, commit editingStyle: UITableViewCellEditingStyle, forRowAt indexPath: IndexPath)
{
//删除
if editingStyle == UITableViewCellEditingStyle.delete
{
dataMutableArray.removeObject(at: indexPath.row)
tableView.deleteRows(at: [indexPath], with: UITableViewRowAnimation.fade)
let array = dataMutableArray
UserDefaults.standard.set(array, forKey: "memberList")
if dataMutableArray.count == 0
{
tableView.backgroundView = tvBackgroundView
}
}
}
###列表项的移动
//编辑状态下的移动
override func tableView(_ tableView: UITableView, moveRowAt sourceIndexPath: IndexPath, to destinationIndexPath: IndexPath)
{
if sourceIndexPath != destinationIndexPath
{
let moveItem = dataMutableArray[sourceIndexPath.row]
dataMutableArray.removeObject(at: sourceIndexPath.row)
dataMutableArray.insert(moveItem, at: destinationIndexPath.row)
let array = dataMutableArray
UserDefaults.standard.set(array, forKey: "memberList")
}
}
###点击cell进入编辑页
//点击
override func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath)
{
tableView.deselectRow(at: indexPath, animated: true)
let vc = AddCardViewController()
vc.itemDic = (dataMutableArray[indexPath.row] as! NSDictionary) as! [String : String]
self.navigationController?.pushViewController(vc, animated: true)
}
