I am creating a sort of the File Directory like a Finder in Xcode Cocoa Objc-C.
I have created a collection view with many square buttons and each button opens up a different file located in the app. What I have done until now is populated each button with the screenshots from the files (so that it would look like a Finder). However, I was wondering if is another way retrieving the icons/images of the files?
Thank you.

My goal is to display simple PDF file (stored locally for example) in the WebView control. Can I bind path of the file to the Source property of the WebView? Or what is the correct way to show PDF in UWP?
P.S. and if the only option is to do like here - how must I add pdf.js to my project??
My goal is to display simple PDF file (stored locally for example) in the WebView control.
If you want to display pdf in WebView control, then the methods in Display a Local PDF File in a WebView is most like the only way to solve your problem.
You can follow the steps in the xamarin official document, and here are some additional tips we need to pay attention to:
After downloading pdfjs, for UWP app, you need to copy the entire folder into the Assets folder, make sure that the folder is named "pdfjs", otherwise you will need to modify the code to change the path.
Your .pdf file should be stored into the Content folder under the Assets folder, it means you will need to create a new folder named "Content" under Assets and copy your .pdf file into this folder. Otherwise, you will also need to modify the code to change the path.
After copying your .pdf file into the "Content" folder, don't forget to change the Build Action of this file to Content like this:
Or what is the correct way to show PDF in UWP?
In uwp app, you can use Image to show PDF file, you can refer to the official PDF document sample. But I don't know if PDF can be displayed as Image in Android and IOS apps, since you're developing a cross-platform project, I think it's better to use the built-in method to solve such problem.
If a demo for xamarin UWP is needed, you can leave a comment, I will upload my demo later.
I am working on project where I have TIFF files in a folder and I want to view those in browser one by one using First, Next, previous, last buttons on the screen. Can anyone suggest how to accomplish this?
I am able to view single file using iTextSharp, but how to proceed for above? Please help.
I am creating a Mac App, using NSDocument, that stores a custom class of documents to iCloud.
I was able to get the program to store documents to iCloud quite easily by just Code Signing it, Sandboxing it, and adding iCloud entitlements; however, I'm still encountering a problem where when I trigger an iCloud conflict and the program drops down the sheet allowing the user to resolve the conflict the rows in the sheet do not show the small image of the document (like Preview and TextEdit do).
Additionally, when I click on the area where the image should be (it's blank) it opens up a Quick Look window that just displays an image of the Document Icon together with some other information as opposed to a snap shot of the actual file like Preview and TextEdit do.
I have not found any information in Apple's documentation that explains what I need to do to implement the same behaviour as Preview and TextEdit.
So far I've been surprised by how easily I've been able to get all of the functionability of not only the Auto Saves and the Versions browser, but also saving to the Cloud. NSDocument seems to do all of this for the developer (resolving iCloud Conflicts, etc.), as Apple's documents says it does, but again I'm not getting this other behaviour and I don't want to reinvent the wheel by writing code that is not needed.
I'm thinking that the answer might lie somewhere with implementing a Quick Look thumbnail (for the small image in the table in the sheet) and a Quick Look preview for the larger preview of the document when that in the sheet is clicked on, but this seems like a lot of work and I'm afraid of losing some of the other build-in functions of NSDocument if I start "trapping" NSDocument routines up the food chain so to speak.
Has anyone else encountered this problem and found the easiest solution?
Update: Dec. 25/12
I've finally figured out that the problem is I need a QuickLook generator to display both a QL Thumbnail (which shows up in the table in the conflicts sheet) and a QL Preview (which is displayed when a user clicks on the Thumbnail)
I ended up creating the QL generator project, and afterwards creating a workspace which I added my main project and the QL generator project to. After that I added a Copy Files Build Phase to the main project to copy the QL generator into the main Application bundle.
I am building an AIR app which will be kind of like Dropbox. It will allow users to sync their files between various OSs. What I would like to know is that how can i change the default file system's file icons (add an overlay for eg) for states like - Synced and Syncing, the way Dropbox does it ??
On Windows i found out that Dropbox edits the registry files to insert the overlay icons..not yet sure how they do it in MAC OS X though.
I saw some threads here asking similar questions about AIR, but none referencing how to change file's icons. Hoping to get a solution for this from the various experts .. Please suggest any ideas if you know how it can be accomplished. Much thanks.
A simple yet effective solution would be to use icons that are only internal to your application : just embed in your application files some transparent pictures representing the various states of your files (with only the small part telling in which state it is, with the rest totally transparent), that you will add at runtime above the displayed icons.
Since you can get the actual icon of your files, just draw them into a BitmapData (if needed) & add an overlay with theses custom images, using the one related to your file's state in your application.
And one step further could be to store in your AIR application folder any resulting icons for future use (check what types of files you already have, and if your new file type isn't in thoses, export the various icons with your custom overlays to PNG files directly on the user device, for re-loading them the next time the application is opened).
I am making a custom file type, and I would like to have my application set the icon for the file without changing th icons of other files of the same type. Here is basically what I want users to go through to set the icon.
Open the application
Push a button (opens an NSOpenPanel)
Select an icon
Save the file
An alternative is to use my very simple, built in image editor. How can I accomplish this?
A good example is an image file. If you save an image from Photoshop, the file's icon is a miniature version of the image you saved. I want it to look and act just like that, if possible. Any ideas?
Edit: The file is supposed to save NSData. It is not actually an image file, but it includes the icon image.
Just use the setIcon:forFile:options: method of NSWorkspace, which will do exactly what you want.
