Description

On iOS the 2nd image which is being read in by filereader is not being loaded but on Android it works as expected. *+Test Case:+*

var win = Ti.UI.createWindow({
	backgroundColor:'white'
});


var earthFile,
  earthFileStream,
  earthBuffer;

function fileReader(args) {
  if (args.bytesProcessed === -1) {
    Ti.API.error('Done');
    Ti.API.info(earthBuffer.toBlob().height + ' . ' + earthBuffer.toBlob().width + ' . ' + earthBuffer.toBlob().mimeType);
    earthImage.image = earthBuffer.toBlob();
    Ti.API.info(earthImage.image.height + ' . ' + earthImage.image.width + ' . ' + earthImage.image.mimeType);
    earthBuffer.release();
    earthImage.animate({
      opacity: 1,
      duration: 100
    });
  } else {
    Ti.API.error(args.bytesProcessed + ' of ' + args.totalBytesProcessed);
    if (earthBuffer === null) {
      earthBuffer = Ti.createBuffer();
    }
    earthBuffer.append(args.buffer);
  }
}

function loadEarth() {
  earthImage.image = null;
  earthImage.opacity = 0;
  earthFile = Ti.Filesystem.getFile(Ti.Filesystem.resourcesDirectory, '/Earth.jpg');
  earthFileStream = Ti.Filesystem.openStream(Ti.Filesystem.MODE_READ, earthFile.nativePath);
  earthBuffer = null;
  Ti.Stream.pump(earthFileStream, fileReader, 512, true);
}

var fishImage = Ti.UI.createImageView({
  left: '10dp',
  top: '10dp',
  right: '10dp',
  height: '200dp',
  image: '/ClownFish.jpg'
});
win.add(fishImage);

var earthImage = Ti.UI.createImageView({
  left: '10dp',
  bottom: '10dp',
  right: '10dp',
  height: '200dp',
  opacity: 0
});
earthImage.addEventListener('singletap', loadEarth);
win.add(earthImage);

loadEarth();
win.open();

*+Test Steps:+*

Create an application with the test case above

Make sure app thinning is disabled in the tiapp.xml

add the two images attached below into the resources folder

Run application on iOS

*+Actual result:+* 2nd image does not load and nothing is logged in the console. *+Expected result:+* 2nd image should load and log the following

[ERROR]  Done
[INFO]   1600 . 2560 . image/jpeg
[INFO]   1600 . 2560 . image/jpeg

Workaround is add following line - earthFileStream.addEventListener('pump', fileReader); inside function loadEarth .
