iOS开发 swift -- 获取相册相机

一 代理

swift一定要遵循UIImagePickerControllerDelegate,UINavigationControllerDelegate俩个代理

二 info.plist

    在info.plist中加入安全域名白名单(右键info.plist用source code打开)    <key>NSCameraUsageDescription</key>    <string>访问相机</string>    <key>NSPhotoLibraryUsageDescription</key>    <string>访问相册</string>

三 代码示例

func addIcon()  {        let alertAction = UIAlertController.init(title: nil, message: nil, preferredStyle: .actionSheet)        alertAction.addAction(UIAlertAction.init(title: "获取相机", style: .default, handler: { (alertCamera) in            let picker:UIImagePickerController = UIImagePickerController()            picker.delegate = self as UIImagePickerControllerDelegate & UINavigationControllerDelegate            picker.sourceType = .camera            picker.allowsEditing = true            if UIImagePickerController.isSourceTypeAvailable(.camera){                self.present(picker, animated: true, completion: { () -> Void in                })            }else{                MBProgressHUD.showForError(to: self.view, text: "为授予防问相机权限", completion: nil)            }        }))        alertAction.addAction(UIAlertAction.init(title: "获取相册", style:.default, handler: { (alertPhpto) in            let picker:UIImagePickerController = UIImagePickerController()            picker.delegate = self as UIImagePickerControllerDelegate & UINavigationControllerDelegate            picker.sourceType = .photoLibrary            picker.allowsEditing = true            if UIImagePickerController.isSourceTypeAvailable(.photoLibrary){                self.present(picker, animated: true, completion: {                    () -> Void in                })            }else{                MBProgressHUD.showForError(to: self.view, text: "为授予防问相册权限", completion: nil)            }        }))        alertAction.addAction(UIAlertAction.init(title: "取消", style: .cancel, handler: { (alertCancel) in        }))        self.present(alertAction, animated: true, completion: nil)    }    // MARK: ImagePicker Delegate 选择图片成功后代理    func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {        if let chosenImage =  info[UIImagePickerControllerOriginalImage] as? UIImage {            picker.dismiss(animated: true) {                self.iconImage.image = chosenImage            }        //处理传入后台        }    }

四 上传到后台

    /// 上传图片    ///    /// - Parameters:    ///   - path: <#path description#>    ///   - image: <#image description#>    ///   - completion: <#completion description#>    class func uploadImage(path: String, image: UIImage, completion: @escaping (_ succeeded: Bool, _ url: String?) -> Void) {        /* 签名 可忽略        let timestamp  = String(Int(NSDate().timeIntervalSince1970 * 1000))        var _paramters = [String: Any]()        _paramters["timestamp"] = timestamp        let sortedKeys = _paramters.keys.sorted()        var temp = sortedKeys.map({ "\($0)=\(_paramters[$0]!)" }).joined(separator: "&")        temp += "&--------"        let sign = temp.md5().uppercased()        _paramters["sign"] = sign        */        Alamofire.upload(multipartFormData: { (multipartFormData) in            let data = UIImageJPEGRepresentation(image, 0.9)            multipartFormData.append(data!, withName: "file", fileName: "image.png", mimeType: "image/png")            for (key, value) in _paramters {                multipartFormData.append((value as AnyObject).data(using: String.Encoding.utf8.rawValue)!, withName: key)            }        }, to: Constant.baseURL + path) { (result) in            switch result {            case .success(let upload, _, _):                upload.responseJSON(completionHandler: { (response) in                    completion(true, JSON(response.data!)["data"].string)                })            case .failure(let error):                print(error)                completion(false, nil)            }        }    }

如有不妥，请多多指教
