I have import contacts to Iphone using CardDAV.
An strange thing happened here for the Photo attribute.
I sent Photo data to Iphone this way,
PHOTO;ENCODING=b;TYPE=JPG: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`
and so on .....
While Iphone return it in this way,

I need to compare the image and i am unable to do this due the photo data return by IPhone.
Note: Every time Iphone return the photo data different while image is same.
Any body knows what way Iphone is using to transform Image.
The client is just adding proper folding as per https://www.rfc-editor.org/rfc/rfc2426#section-2.6
In other words, you are not supposed to have lines longer than 75 characters in a vCard. You need to fold those.

So I have app where I want to let users to share screenshot of score to facebook etc... I'm using SocialShare widget. In documentation it says to set path to image like this: "image:fileToShare.nativePath", but I'm not really sure how to set it. Another problem is that I need to share picture that has always different name, it saves screenshots with names like tia7828157.png,tia107997596.png... in folder in device internal memory in pictures/enigmania/ I'm new to appcelerator, so I dont know if there is something like wildcard I could use for this? Thanks for any help.
This is my code so far which I know is wrong, I know the widget works because it shares text without problem:
function shareTextWidget(e){
// share text status
var socialWidget=Alloy.createWidget('com.alcoapps.socialshare');
socialWidget.share({status:"Enigmania kvíz",androidDialogTitle:"hoho",image:test.png/pictures/enigmania});
}
You should use Ti.Filesystem class methods/properties to get the path of any file located on internal or external storage.
Also aware of the permissions of reading storage on Android 6+. Use Storage Permissions before accessing any file on Android 6+.
Simple code snippet to create a directory on internal storage at this location: pictures/enigmania and then write an image file of captured view in this directory.
function shareTextWidget(e){
var directory = Ti.Filesystem.getFile(Ti.Filesystem.externalStorageDirectory, 'pictures/enigmania');
!directory.exists() && directory.createDirectory();
var fileToShare = Ti.Filesystem.getFile(directory.resolve(), 'screen.jpg');
fileToShare.write($.SCREENSHOT_VIEW.toImage()); // write the blob image to created file
var socialWidget=Alloy.createWidget('com.alcoapps.socialshare');
socialWidget.share({status:"Enigmania kvíz",androidDialogTitle:"hoho",image:fileToShare.nativePath});
}
This code should work without any issues.
Note that $.SCREENSHOT_VIEW is the View ID for which you will take screenshot, so it depends on you how you maintain your View positions in order to capture correct screenshot, but point is to use Ti.UI.View toImage() method to capture the screenshot of particular view.
Let me know if this works for you or not, else we can look into other methods by getting your exact requirements. Good Luck!!!!
Im trying to load(and upload) images in my app(by picture path).
This is working in my simulator. everything works there. only when im trying to do this on the iphone itself it won't work and i see just the empty UIImageviews.
The paths are loaded the same as in the simulator. And originate from:
PHImageManager.defaultManager().requestImageDataForAsset(asset, options: nil)
{
imageData,dataUTI,orientation,info in
cell.setString(info["PHImageFileSandboxExtensionTokenKey"] as String,name:dataUTI as String)
}
And the PHImageFileSandboxExtentionTokenKey is split into the data and the url when loading the image.
this results in the simulator as :
/Users/Twizzler/Library/Developer/CoreSimulator/Devices/3E671415-8B83-44DA-870F-19BF2BC11F8F/data/Containers/Data/Application/8872109F-3784-40EB-BEB6-4E9FDABE013D/Documents/1613945_10200645161051698_4122753901212984922_n.jpg
and in the iphone as:
/private/var/mobile/Media/DCIM/102APPLE/IMG_2607.JPG
Im loading the image like this:
let image = UIImage(named: "/private/var/mobile/Media/DCIM/102APPLE/IMG_2607.JPG")
cell.imageView.image = image
in this case i put the image url hardcoded (this is in the final app an array of images)
I don't get an error or stack trace. When placeing a breakpoint im seeing the image information in the same way as the simulator
as suggested by the answer im now trying to load them as follows:
let image = UIImage(contentsOfFile: "/private/var/mobile/Media/DCIM/102APPLE/IMG_2607.JPG")
cell.imageView.image = image
This isn't working and i can't upload the files
That’s not how imageNamed works—as the documentation states, that looks for an image with the given name inside your app’s bundle. Try imageWithContentsOfFile.
Well i fixed it! after some puzzling days im now using this way to access upload and
cell.imageView.image = UIImage(data: array[indexPath.row][0] as NSData)
This shows the image. I can save the NSData in the CoreData and reload the image on this way.
To lighten the load on the system im using this:
cellData.checked = 1
var imageData = UIImageJPEGRepresentation(cell.imageView.image, 1)
self.array.append([imageData,cellData.imageData] )
let myObj : ViewControllerImagePicker = self.parentViewController as ViewControllerImagePicker
let textfield: UILabel = myObj.amountLabel! as UILabel
textfield.text = String(self.array.count )
cell.textLabel.alpha = 1
this code is being called when there is clicked on a cell. by setting the cellData.imageData i can recall the cells (when clicking back to the collection view)
I do not know if the way im doing it is correct or works with more that 10 files because of data usage problems. But in my case with a max of 6 selected pictures it works like a charm
The simulator works completely different than a real device when it comes to files, the app bundle and sandboxing.
For starters the simulator will let you write to and add or change files in your app bundle. iOS running on a real device won't let you do this.
You can't hardcode any paths in your app. Even if it works today or on your device in test mode that doesn't mean it will work on a released version. And even if it does it could stop working on any update. Apple several times has changed where things are stored and the path structure in the phone. And where you are allowed to write.
Make bundle calls to get the path locations of standard folders.
Use the assets library to load images from the photo library, or to save them there.
There are tons of resources and tutorials online on how to do this.
I'm trying to wrangle the new photo features of iOS 8's photo editing capabilities. Their documentation is very sparse so I'd love some input from you as to what might be going on.
I am trying to fetch ALL the images the user has saved. I am doing a fetch but it keeps telling me the result size is 0. It also shoots out a weird error along with it
func initController()
{
_userAlbums = PHCollectionList.fetchTopLevelUserCollectionsWithOptions(nil)//GET PERMISSION BEFORE DOING THIS
println("Albums count is \(_userAlbums.count)") //error when printing this
}
This prints out
2014-10-27 17:43:50.254 appiOS[4854:732084] [PLLogging] ***** Error: logging directory does not exist
/var/mobile/Library/Logs/CrashReporter/DiagnosticLogs/
Albums count is 0
There are at least 100 images on the iPad I am using. Any idea what I am doing wrong?
Update:
Using
_userAlbums = PHAsset.fetchAssetsWithOptions(nil)
Works
There are at least 100 images on the iPad I am using. Any idea what I am doing wrong?
You are not doing anything wrong. Your expectations seem a bit out of whack, though. The statement "there are at least 100 images" seems indicative of a deeper misconception, because, after all, PHCollectionList.fetchTopLevelUserCollectionsWithOptions has nothing to do with images. It has to do with, uh, top level user collections. Evidently your device doesn't have any of those.
But now go to the Photos app on your iPad and make a few albums. Those are top level user collections! So then run your app again. Assuming you've been granted permission to access the photo library, now your logging will result in a number larger than 0.
Is there a way to get raw data of image from UIPasteboard instead of UIImage if it's copied by another app such as photos or mobile safari?
I'm currently facing wired differences between IOS 6.0 and IOS 6.1(7.0 also)
In IOS 6.0, UIPasteboard's item of the copied image by photos or mobile safari contains raw data of the image.
But In IOS 6.1 and above, it contains UIImage instead of raw data.
In IOS 6.0, copied item of UIPasteboard is below
Printing description of array:
<__NSArrayM 0x8a804c0>(
{
"com.compuserve.gif" = <47494638 39614002 ...... 3b3a2000 3b>;
"public.url" = "url of the image....";
}
)
In IOS 6.1 and above, it contains UIImage instead of raw data.
Printing description of array:
<__NSArrayM 0xa25b7b0>(
{
"com.compuserve.gif" = "<UIImage: 0x9429570>";
"public.url" = "url of the image...";
}
)
If that image format is PNG or JPEG, it's not that bad.
(I still have to compress again if it's JEPG though.)
But when I try to paste animated gif image, it becomes more complicated.
I don't know even it's passible to create animated gif image from normal UIImage.
I can download again from original url, but downloading data that I already have seems not good solution I think.
And also, if it's copied from photos app, there's no such url. (there's some mysterious uri named "com.apple.mobileslideshow.asset-object-id-uri" that is undocumented instead of url)
There seems a workaround, because when I try to do exactly same action between photos and email app, It works properly
Any suggestions?
Well now, I figured it out myself.
You can simply get raw (binary)data of the image form general pasteboard by sending
dataForPasteboardType:(NSSting*)PasteboardType message to general pasteboard, if it's copied from Apple's built-in Mobile Safari or Photos App. (#"com.compuserve.gif" for the pasteboard type in my case)
I myself feel a bit foolish for not having checked all the passible methods sooner. :(
My confusion comes from items property of the UIPasteboard.
I thought that items are containing all of data of current pasteboard. So I try to save that array from pasteboard and want to use it later, but I were totally wrong.
As documented in UIPasteboard Class Reference, the items property contains dictionary with key being the representation type and the "value" the object associated with that type.
At this point of time, The "value" refers really "value" of the representation, not the data of that type. This meaning of the "value" is the same as the value of thesetValue: forPasteboardType: method.
On the other words, you cannot retrieve raw(binary) data of the image from items property, even if you set the image to the pasteboard by sending setData: forPasteboardType: message.(I tested it on IOS 7)
In addition, raw data of the image from items property in IOS 6.0 seems a bug of that OS version. (This may not true, it's just my opinion)
You can get NSData from UIPasteboard if you specify right PasteboardType:
NSData* pasteData = [[UIPasteboard generalPasteboard] dataForPasteboardType:(NSString*)kUTTypeJPEG];
Do not forget to import
<MobileCoreServices/MobileCoreServices.h>
The UIPasteBoard will contain whatever is placed in it. It's up to the app that is copying to the paste board to put the contents in the proper format. The app can place items as raw binary data or as objects such as UIImage in the paste board.
If you're getting something different between iOS versions, you're probably using different versions of the app or it's simply copying things differently.
You're right that you can't represent an animated GIF in a UIImage because a UIImage only contains a single image. Perhaps the app is just copying the first frame's bitmap data in that case?
You can convert a UIImage to raw JPEG data using UIImageJPEGRepresentation.
My understanding currently is that:
CameraUI
I can use the CameraUI to access the built in camera for MediaType.VIDEO and that delegates to the built-in video camera app and lets me record a video. My app does that now.
When I stop recording and click the "Use" button, I am returned to my app and theoretically I have a valid MediaPromise.
iOS does -not- provide a valid/usable url/filename to the recorded video (or to photos) and so I would have to use a Loader to bring-in/use/access the 'recorded' video... AND... iOS does not actually create a file anywhere on the device, most importantly, in the Camera Roll where one would expect by the normal behavior when uses the system native camera/video app.
The documentation says that the Loader can load various image types and SWFs but nothing about video data, so I conclude from that that I cannot actually use the CameraUI to generate a valid MediaPromise that I can then pass to a Loader class or similar to read in the information created by the system camera and then manipulate (upload, save to applicationStorageDirectory, and/or display in one of the two video player components available in the API).
CameraRoll
I can have video entities in the iOS Camera Roll but the AS3/Air3.5 CameraRoll class won't let me view/access/reference them in any way.
Normal File I/O
All my attempts to use the Air3.5 File classes to browse to the storage location of the iOS Camera Roll have been rebuffed.
------- Questions -------
Am I correct in believing that there is a way to take video but no way to use the video that's been captured. (No way to use the resulting MediaPromise successfully).
I believe you can take video and access it using Android, but there's nothing in the documentation that says that you cannot using iOS.
Am I correct in believing that iOS sandboxes apps so that they cannot browse to video/photo storage using standard File I/O, but only through the apparently non-workable means I've tried (CameraUI & CameraRoll)
Am I wrong to think that these should be rather obvious NEEDS that one can achieve using the XCode Objective C++ etc route but the AIR Mobile Framework does not allow either because of Apple blocking functionality or because Adobe has failed to meet reasonable expectations?
One item of ironic note to convey. If I use the iOS system camera app to record a video, a thumnail of that video then appears in the Gallery/Camera Roll, and of course, I can share it or view it, or whatever... If I use AIR's CameraRoll.browseForImage(), provided I haven't used the camera to take another image, when it shows me the folder where the pictures are stored, the folder icon uses the thumbnail of the last object added... in this case, the video I took, but if I then enter the folder, the video cannot be found. It's teasing us. It knows it's there, but it is apparently forbidden fruit.
I can't answer all your questions, so this entry may not be acceptable, but I found this page while searching a solution for some the problems you described and thought that someone else may find this answer (partially) useful.
To save the movie you just took you need to open and read the data from the promise.
The iOS won't save the file anywere, so the MediaPromise.file is always null.
This is my solution to the problem:
private var camera:CameraUI;
private var dataInput:IDataInput;
public function recordVideo():void
{
// Start the camera and ask for a video
camera = new CameraUI();
camera.addEventListener(MediaEvent.COMPLETE, onCameraComplete);
camera.launch(MediaType.VIDEO);
}
private function onCameraComplete(event:MediaEvent):void
{
// event.data is a MediaPromise and MediaPromise.open() returns a IDataInput
// Let's cast it to a dispatcher and check when it's complete
dataInput = event.data.open();
var dispatcher:IEventDispatcher = IEventDispatcher(dataInput);
dispatcher.addEventListener(Event.COMPLETE, onDataInputComplete);
}
private function onDataInputComplete(event:Event):void
{
// We can do whatever we want with the data, so we'll store it in a File
var file:File = new File();
var bytes:ByteArray = new ByteArray();
var stream:FileStream = new FileStream();
// Reading the data from the opened MediaPromise
dataInput.readBytes(bytes);
stream.open(file, FileMode.WRITE);
stream.writeBytes(bytes, 0, bytes.bytesAvailable);
stream.close();
}
Also, I'm still looking for a way to put the movie in the CameraRoll
