swift语言IOS8开发战记19UIImagePickerController

  我们接着上一话的内容来讲，首先在我们添加一个餐馆的页面中把点击的背景色取消掉使用的是以下语句：

cell.selectiOnStyle= UITableViewCellSelectionStyle.None

func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {//点击行的代理方法
        var row:NSInteger = indexPath.row
        if row == 0{
        self.didClickedImageView()
        }

func didClickedImageView(){
    let imagePicker = UIImagePickerController() //选择图片
    let isAvailable = UIImagePickerController.isSourceTypeAvailable(UIImagePickerControllerSourceType.Camera)
        imagePicker.sourceType = .PhotoLibrary
        if isAvailable {
            imagePicker.sourceType = .Camera
        }
        self.presentViewController(imagePicker, animated: true, completion: nil)
    }

现在我们希望我们选择了照片之后可以把该照片保存到第一行之中，这就需要在点击第一行的时候把当前的类当做imagePicker的代理，所以把点击第一行所触发的方法didClickedImageView修改如下：

func didClickedImageView(){
    let imagePicker = UIImagePickerController() //选择图片
    let isAvailable = UIImagePickerController.isSourceTypeAvailable(UIImagePickerControllerSourceType.Camera)
        imagePicker.sourceType = .PhotoLibrary
        imagePicker.delegate = self//代理设为自己
        if isAvailable {
            imagePicker.sourceType = .Camera
        }
        self.presentViewController(imagePicker, animated: true, completion: nil)
    }

 func imagePickerController(picker: UIImagePickerController!, didFinishPickingImage image: UIImage!, editingInfo: [NSObject : AnyObject]!) {//保存图片
        imageView.image = image
            picker.dismissViewControllerAnimated(true, completion: nil)
        }

接下来我们来实现下面这几行，代码如下：

 func configureCell(cell:UITableViewCell, indexPath: NSIndexPath){
        let row:NSInteger = indexPath.row
        var nameLabel = UILabel(frame: CGRectMake(10, 5, 200, 15))
            switch row{
        case 0:
         imageView = UIImageView(frame: CGRectMake(0, 0, 320, 250))
            imageView.image = UIImage(named: "camera")
            imageView.cOntentMode= UIViewContentMode.ScaleAspectFit
            cell.addSubview(imageView)
        case 1:
            nameLabel.text = "Name"
            cell.addSubview(nameLabel)
                var textFiled = UITextField(frame: CGRectMake(10, 20, 250, 40))
            textFiled.placeholder = "Restaurant Name"
                cell.addSubview(textFiled)
        case 2:
            nameLabel.text = "Type"
            cell.addSubview(nameLabel)
            var textFiled = UITextField(frame: CGRectMake(10, 20, 250, 40))
            textFiled.placeholder = "Restaurant Type"
            cell.addSubview(textFiled)
            
        case 3:
            nameLabel.text = "Location"
            cell.addSubview(nameLabel)
            var textFiled = UITextField(frame: CGRectMake(10, 20, 250, 40))
            textFiled.placeholder = "Restaurant Location"
            cell.addSubview(textFiled)
        default:
            nameLabel.text = "Have you been here？"
            cell.addSubview(nameLabel)
            
            
        }
    }

在最后一栏中需要加两个按钮，一个YES和一个NO，然后再导航栏中增加一个标题，NewViewController的完整代码如下：

import UIKit

class NewViewController: UIViewController,UITableViewDataSource,UITableViewDelegate,UINavigationControllerDelegate,UIImagePickerControllerDelegate  {
let identifier = "newCell"
    var imageView:UIImageView!
    override func viewDidLoad() {
        super.viewDidLoad()
self.view.backgroundColor = UIColor.orangeColor()
        
        //增加一个tableview
        var tableView = UITableView(frame: self.view.bounds, style: .Plain)
        tableView.dataSource = self
        tableView.delegate = self
        tableView.registerClass(UITableViewCell.self, forCellReuseIdentifier: "newCell")
        self.view.addSubview(tableView)
        self.navigationItem.title = "New Restaurant"
        
    }
    func numberOfSectionsInTableView(tableView: UITableView) -> Int {
        return 1
    }
    func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return 5
    }
    func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
        
        let cell = UITableViewCell(style: .Default, reuseIdentifier: "newCell")
        self.configureCell(cell, indexPath: indexPath)
        cell.selectiOnStyle= UITableViewCellSelectionStyle.None//选中的背景色
        return cell
    }
    func tableView(tableView: UITableView, heightForRowAtIndexPath indexPath: NSIndexPath) -> CGFloat {
        var row:NSInteger = indexPath.row
        var rowHeight:CGFloat = 62
        if row == 0
        {
        rowHeight = 250
        }
        return rowHeight
    }
    func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
        var row:NSInteger = indexPath.row
        if row == 0{
        self.didClickedImageView()
        }
    }
    
    func configureCell(cell:UITableViewCell, indexPath: NSIndexPath){
        let row:NSInteger = indexPath.row
        var nameLabel = UILabel(frame: CGRectMake(10, 5, 200, 15))
            switch row{
        case 0:
         imageView = UIImageView(frame: CGRectMake(0, 0, 320, 250))
            imageView.image = UIImage(named: "camera")
            imageView.cOntentMode= UIViewContentMode.ScaleAspectFit
            cell.addSubview(imageView)
        case 1:
            nameLabel.text = "Name"
            cell.addSubview(nameLabel)
                var textFiled = UITextField(frame: CGRectMake(10, 20, 250, 40))
            textFiled.placeholder = "Restaurant Name"
                cell.addSubview(textFiled)
        case 2:
            nameLabel.text = "Type"
            cell.addSubview(nameLabel)
            var textFiled = UITextField(frame: CGRectMake(10, 20, 250, 40))
            textFiled.placeholder = "Restaurant Type"
            cell.addSubview(textFiled)
            
        case 3:
            nameLabel.text = "Location"
            cell.addSubview(nameLabel)
            var textFiled = UITextField(frame: CGRectMake(10, 20, 250, 40))
            textFiled.placeholder = "Restaurant Location"
            cell.addSubview(textFiled)
        default:
            nameLabel.text = "Have you been here？"
            cell.addSubview(nameLabel)
            var leftBtn = UIButton(frame: CGRectMake(10, 30, 50, 25))
            leftBtn.setTitle("YES", forState: .Normal)
                leftBtn.setTitleColor(UIColor.whiteColor(), forState: .Normal)
                leftBtn.backgroundColor = UIColor.redColor()
                cell.addSubview(leftBtn)
            var rightBtn = UIButton(frame: CGRectMake(90, 30, 50, 25))
            rightBtn.setTitle("NO", forState: .Normal)
            rightBtn.setTitleColor(UIColor.whiteColor(), forState: .Normal)
            rightBtn.backgroundColor = UIColor.grayColor()
                cell.addSubview(rightBtn)
            
        }
    }
    
    func didClickedImageView(){
    let imagePicker = UIImagePickerController() //选择图片
    let isAvailable = UIImagePickerController.isSourceTypeAvailable(UIImagePickerControllerSourceType.Camera)
        imagePicker.sourceType = .PhotoLibrary
        imagePicker.delegate = self
        if isAvailable {
            imagePicker.sourceType = .Camera
        }
        self.presentViewController(imagePicker, animated: true, completion: nil)
    }
    
    func imagePickerController(picker: UIImagePickerController!, didFinishPickingImage image: UIImage!, editingInfo: [NSObject : AnyObject]!) {//保存图片
        imageView.image = image
            picker.dismissViewControllerAnimated(true, completion: nil)
        }
