xcode – 以ActionSheet样式访问图片库

概述我正在尝试在注册视图控制器中创建profilePic. profilePic的类型为UI ImageView.我希望能够点击它,以便立即在ActionSheet样式中提取照片库.并且还有一个图像框一个按钮来访问相机.这可能吗？ import UIKitclass SignUpViewController: UIViewController, UITextFieldDelegate, UIPic 我正在尝试在注册视图控制器中创建profilePic. profilePic的类型为UI ImageVIEw.我希望能够点击它,以便立即在ActionSheet样式中提取照片库.并且还有一个图像框一个按钮来访问相机.这可能吗？

import UIKitclass SignUpVIEwController: UIVIEwController,UITextFIEldDelegate,UIPickerVIEwDataSource,UIPickerVIEwDelegate {    @IBOutlet weak var profilePic: UIImageVIEw!    overrIDe func vIEwDIDLoad() {        super.vIEwDIDLoad()        // Do any additional setup after loading the vIEw.        // PROfile PICTURE        let tapGesture = UITapGestureRecognizer(target: self,action: "imageTapped:")        profilePic.addGestureRecognizer(tapGesture)        profilePic.userInteractionEnabled = true    }    func imageTapped(gesture:UIGestureRecognizer) {        if let profile1Pic = gesture.vIEw as? UIImageVIEw {            print("Image Tapped")        }    }

解决方法 请尝试以下代码：

import UIKitclass SignUpVIEwController: UIVIEwController,UIImagePickerControllerDelegate {@IBOutlet weak var profilePic: UIImageVIEw!overrIDe func vIEwDIDLoad() {  super.vIEwDIDLoad()  let tapGesture = UITapGestureRecognizer(target: self,action: "imageTapped:")  profilePic.addGestureRecognizer(tapGesture)  profilePic.userInteractionEnabled = true}func imageTapped(gesture:UIGestureRecognizer) {  if let profile1Pic = gesture.vIEw as? UIImageVIEw {      print("Image Tapped")      showActionSheet()  }}func camera(){    var myPickerController = UIImagePickerController()    myPickerController.delegate = self;    myPickerController.sourceType = UIImagePickerControllerSourceType.Camera    self.presentVIEwController(myPickerController,animated: true,completion: nil)}func photolibrary(){    var myPickerController = UIImagePickerController()    myPickerController.delegate = self;    myPickerController.sourceType = UIImagePickerControllerSourceType.Photolibrary    self.presentVIEwController(myPickerController,completion: nil)}func showActionSheet() {    let actionSheet = UIAlertController(Title: nil,message: nil,preferredStyle: UIAlertControllerStyle.ActionSheet)    actionSheet.addAction(UIAlertAction(Title: "Camera",style: UIAlertActionStyle.Default,handler: { (alert:UIAlertAction!) -> VoID in        self.camera()    }))    actionSheet.addAction(UIAlertAction(Title: "gallery",handler: { (alert:UIAlertAction!) -> VoID in        self.photolibrary()    }))    actionSheet.addAction(UIAlertAction(Title: "Cancel",style: UIAlertActionStyle.Cancel,handler: nil))    self.presentVIEwController(actionSheet,completion: nil)}func imagePickerController(picker: UIImagePickerController,dIDFinishPickingMediawithInfo info: [NSObject : AnyObject]) {    profilePic.image = info[UIImagePickerControllerOriginalimage] as? UIImage    self.dismissVIEwControllerAnimated(true,completion: nil)}}
