Description

This was working fine with SDK 3.3.0, but since 3.4.0-beta, my app cannot load previously saved images anymore... message = "invalid image type"; [ERROR] : nativeLocation = "-[TiUIImageView setImage_:] (TiUIImageView.m:685)"; [ERROR] : nativeReason = "expected TiBlob, String, TiFile, was: TiBlob"; Strangely, it seems to expect a TiBlob, and gets one, but doesn't load it...

Thank you for the report. Can you please provide a test case?

Here's a very small part of my app, causing the bug. First pick an image, then click "Show Image" to load it.

   <Alloy>
   	<Window class="container" layout="vertical">
   		<Button title="Pick Image" onClick="PickImage" top="50" />
   		<Button title="Show Image" onClick="ShowImage" />
   		<ImageView id="imageView" width="Ti.UI.FILL" height="300"></ImageView>
   	</Window>
   </Alloy>

   var imageFilename = "test.jpg";
   function PickImage() {
   	Ti.Media.openPhotoGallery({
   		mediaTypes: [Ti.Media.MEDIA_TYPE_PHOTO],
   		success: function(event) {
   			var f = Ti.Filesystem.getFile(Ti.Filesystem.applicationDataDirectory + imageFilename);
   			if (f.exists()) {
   				f.deleteFile();
   				f = Ti.Filesystem.getFile(Ti.Filesystem.applicationDataDirectory + imageFilename);
   			}
   			f.write(event.media);
   		}
   	});
   }
   function ShowImage() {
   	var f = Ti.Filesystem.getFile(Ti.Filesystem.applicationDataDirectory + imageFilename);
   	if (f.exists()) {
   		var imageBlob = f.read();
   		$.imageView.image = imageBlob;
   	}
   }
   $.index.open();

Steps to Test

1. Click "Pick Image" 2. Select a photo 3. Click "Show Image" 4. The image should now be visible at the bottom of the screen.

Test Code

   var win = Ti.UI.createWindow({
   	backgroundColor: 'white'
   });
   win.open();
   
   var button1 = Ti.UI.createButton({
   	title: 'Pick Image',
   	top: 50,
   	height: 50
   });
   button1.addEventListener('click', function() {
   	PickImage();
   });
   win.add(button1);
   
   var button2 = Ti.UI.createButton({
   	title: 'Show Image',
   	top: 150,
   	height: 50
   });
   button2.addEventListener('click', function() {
   	ShowImage();
   });
   win.add(button2);
   
   var imageView = Ti.UI.createImageView({
   	width:Ti.UI.FILL,
   	height:300,
   	bottom: 0,
   	backgroundColor: 'blue'
   });
   win.add(imageView);
   
   var imageFilename = "test.jpg";
   function PickImage() {
       Ti.Media.openPhotoGallery({
           mediaTypes: [Ti.Media.MEDIA_TYPE_PHOTO],
           success: function(event) {
               var f = Ti.Filesystem.getFile(Ti.Filesystem.applicationDataDirectory + imageFilename);
               if (f.exists()) {
                   f.deleteFile();
                   f = Ti.Filesystem.getFile(Ti.Filesystem.applicationDataDirectory + imageFilename);
               }
               f.write(event.media);
           }
       });
   }
   function ShowImage() {
       var f = Ti.Filesystem.getFile(Ti.Filesystem.applicationDataDirectory + imageFilename);
       if (f.exists()) {
           var imageBlob = f.read();
           imageView.image = imageBlob;
       } else {
       	console.log("image does not exist");
       }
   }

Verified fix on: Mac OSX 10.9.4 Appcelerator Studio, build: 3.4.0.201409131030 Titanium SDK build: 3.4.0.v20140916151649 Titanium CLI, build: 3.4.0-rc4 Alloy: 1.5.0-rc2 Xcode6 GM Seed iPhone Device 5 (8.0 GM Seed) Used the above test code and built to device. The image was shown on the screen after I selected it and clicked 'Show Image'. Closing ticket.
