ios - 捕获并存储用相机拍摄的照片到本地数据库/PhoneGap/Cordova/iOS

Question

我目前正在使用 Phonegap/Cordova 和 jQuerymobile 为 iOS 构建一个应用程序。这个想法是用相机拍照并存储捕获的图像以备将来使用。我想将路径/文件名存储到我的本地数据库中，并将图片文件移动到 iPhone 中的持久位置。

有人可以给我举个例子吗？

Answer 1

好的，这是解决方案。

• 在Html文件中

• 我有一个图像标签，用于显示相机拍摄的照片:

• 我有一个运行拍照功能的按钮:拍照

• 拍照功能是(拍照时，'smallImage'id的scr中填充照片的路径)

  function capturePhoto() {
  // Take picture using device camera and retrieve image as base64-encoded string
      navigator.camera.getPicture(onPhotoDataSuccess, onFail, { quality: 50 });
  }
  
  //Callback function when the picture has been successfully taken
  function onPhotoDataSuccess(imageData) {                
      // Get image handle
      var smallImage = document.getElementById('smallImage');
  
      // Unhide image elements
      smallImage.style.display = 'block';
      smallImage.src = imageData;
  }
  
  //Callback function when the picture has not been successfully taken
  function onFail(message) {
      alert('Failed to load picture because: ' + message);
  }
  

• 现在我想将图片移动到永久文件夹中，然后将链接保存到我的数据库中:

  function movePic(file){ 
      window.resolveLocalFileSystemURI(file, resolveOnSuccess, resOnError); 
  } 
  
  //Callback function when the file system uri has been resolved
  function resolveOnSuccess(entry){ 
      var d = new Date();
      var n = d.getTime();
      //new file name
      var newFileName = n + ".jpg";
      var myFolderApp = "EasyPacking";
  
      window.requestFileSystem(LocalFileSystem.PERSISTENT, 0, function(fileSys) {      
      //The folder is created if doesn't exist
      fileSys.root.getDirectory( myFolderApp,
                      {create:true, exclusive: false},
                      function(directory) {
                          entry.moveTo(directory, newFileName,  successMove, resOnError);
                      },
                      resOnError);
                      },
      resOnError);
  }
  
  //Callback function when the file has been moved successfully - inserting the complete path
  function successMove(entry) {
      //I do my insert with "entry.fullPath" as for the path
  }
  
  function resOnError(error) {
      alert(error.code);
  }
  

• 我的文件已保存在数据库中以显示它，我将“file://”放在包含图像 src 的行的前面

希望对您有所帮助。J.
