Right now I am developing a macOS WebApp, this includes a WKWebview.
However, when I want to upload or download a file, it doesn't work. When I click, nothing happens! Like, nothing. I click on for example on “choose file” or any other upload button, and the window that should appear to select a file or directory doesn’t show up.
I have been struggling all day long, checking stackoverflow and many other resources and I found many posts related to my problem, but they are all out-dated.
My code is really simple;
- (void)viewDidLoad {
[super viewDidLoad];
// Load the url into the webview
NSURL *url = [NSURL URLWithString:#"https://www.my-website-url.com"];
[self.myView loadRequest:[NSURLRequest requestWithURL:url]];
}
So basically all I want is that I can download and upload files to and from my WKWebView.
It is NOT a duplicate question because I still don't get how to implement the code that Willeke is referring to in the comments.

I am working on an existing project where UIWebview is used to load html string to load js files for loading contents downloaded from our server.Currently UIWebview is not able to load the contents in IOS which is perfectly loading in Android.
I have tried to switch to WKWebView but still no luck.
self.webContentView.delegate = self;
NSString* html = [player getHTMLString];
NSString* baseURL = [player getBaseURLPath];
[self.pageLoadingActivity startAnimating];
[self.webContentView loadHTMLString:html baseURL: [NSURL URLWithString: baseURL]];
EDIT------
After debugging sometime I found I was getting two 1100 error.
It seemed like two file were missing or app was not able to read them.
Now whenever I am hitting shouldStartLoadWithRequest with
request
URL:
file:///Users/ealpha4tech/Library/Developer/CoreSimulator/Devices/2CA71983-9996-44D6-944F-34E3EAFAE96D/data/Containers/Data/Application/6A19ABBA-CB68-4EE4-AC02-6AD3CB8A5A68/Documents/icplayer/icplayer/D2D6AFFF93CB2CFCB1640484F5429D89.cache.html
I am getting 1100 error.(the above file is present though)
So as a guess, I would say [player getHTMLString] is the problem.
NSURLErrorFileDoesNotExist: The specified file doesn’t exist.
This is a local file error.
I'm guessing that -getHTMLString is trying to load a file out of the app, but that file is not being included in the app.
I could help more if you provide 2 things.
Provide the source for -getHTMLString
Use NSLog() to print value of [player getBaseURLPath].
UPDATE
In looking at your output, I noticed …ments/icplayer/icplayer/D2D6A…. I think the proper path should only have one icplayer not two. Look to see if it's getting repeated somehow.
I am using the following code to populate a webView in my Mac app...
NSURL *url = [NSURL URLWithString:#"https://joeworkman.net"];
[self setMainFrameURL:[url absoluteString]];
I would like to be able to capture when there are errors loading this URL and then instead load a local HTML file stored within my app. This way the users gets presented with a presentable error instead of an ugly 500 server error (if that was the case). Not to mention that most users would not know what that meant anyhow.
I have an application that shows presentations that are composed by pages.
Those pages can contain some kinds of media, and one of them is HTML, wich uses an UIWebView component as viewer.
What I need is some way to insert some kind of link into the HTML document so I can jump to another page of my application presentation.
In my research I have found that subclassing UIWebView is not recommended, so I have no clue of how I should handle this.
Many thanks in advance.
Provide:
-webView:shouldStartLoadWithRequest:navigationType:
in your app delegate (ref here).
It will be called each time the web view is about to load new content and give you the chance to do what you need. E.g., this would work if you embed a "file://" kind of URL in your web page:
- (BOOL)webView:(UIWebView*)webView shouldStartLoadWithRequest:(NSURLRequest*)request navigationType:(UIWebViewNavigationType)navigationType {
if ([[[request URL] scheme] isEqual:#"file"])
return YES;

I am adding Dropbox support to my iOS application. Using the official Dropbox API and the tutorials online here I have gotten to the point where Dropbox needs to be authenticated. The code below is what is given to Authenticate when a button is pressed:
//MainViewController.m
....
#implementation CryptoMainViewController
.....
#pragma mark - Dropbox
- (void)didPressLink {
if (![[DBSession sharedSession] isLinked]) {
[[DBSession sharedSession] link];
}
}
But no matter how I change the code, where I put it or what button I link it to, nothing will happen. Using breakpoints I've found that the method does in-fact get triggered. I've even put it in an IBAction, but this gives the same result. What am I doing wrong? How can I get my app to authenticate the end-user?
And, once authenticated, How can I save an NSString to the user's Dropbox?
If this is just totally wrong, then where can I go to find resources on how to do this properly?
The whole tutorial, all of the documentation, api, etc. is available here.
I had the same problem; the reason was that I hadn't set the shared Dropbox session, e.g.
DBSession* dbSession = [[[DBSession alloc] initWithAppKey: #"your_app_key"
appSecret: #"your_app_secret"
root: kDBRootAppFolder] autorelease];
[DBSession setSharedSession: dbSession];
Once that was called the link worked fine.
this answer may be late but im guessing that you already linked your app before and want to do so again. The only way you can have the process of linking taking place again is if you run the following code:
[[DBSession sharedSession] unlinkAll];
You can place it in your viewDidLoad. When you then call didPressLink: the app should open up dropbox app(if available), safari or an in app window asking for your permission to access your dropbox. If this does not happen then the problem is somewhere else. Hope this helps
Does your view implement the <DBLoginControllerDelegate> ?
If so, link Dropbox like so:
DBLoginController* controller = [[DBLoginController new] autorelease];
controller.delegate = self;
[controller presentFromController:self];
I am making an iPad app where you can download files (like PDF, doc, etc) and view them offline.
I already have the view part and you can download a file to the document directory.
As it is now you need to wait for the download to be finished to move on.
This can be solved by putting it in a thread, but what happens when the user downloads multiple files or even download the same file multiple times?
My idea is to make a download queue, with a view for the progress.
Workflow:
The user opens a document and press download, the user gets a message that the download is started and can be viewed in the offline documents view.
The user downloads 3 more documents.
When the user goes to the offline document view the user sees a table view with 4 filled cells. 2 documents are done loading and 2 other are still downloading because there is a download/status bar shown in the table view cell.
The downloaded documents can be viewed or deleted.
The downloads in progress can not be watched (yet) but can be cancelled.
I want to make a threaded download class where you can add urls to be downloaded. the class has methods to cancel and delete document-downloads, but also has methods to return the progress.
If possible the class can handle simultaneous downloads.
The problem is, I don't know where to start?
NSURLConnection is already asynchronous. All you need to do is to create NSURLConnection instances, associate them with your data structures, and have at it.
Here's an example where I assume you have one UIView per item. If you use a table view you can't count on view instances, but instead associate a download with an NSIndexPath, or something else.
#implementation MyDownloadView
- (void)startDownload {
NSMutableURLRequest *req = [[NSMutableURLRequest alloc] initWithURL:myURL cachePolicy:NSURLRequestReloadIgnoringCacheData timeoutInterval:10];
[req setHTTPMethod:#"GET"];
// Set headers etc. if you need
[[[NSURLConnection alloc] initWithRequest:req delegate:self] autorelease];
[req release];
self.responseData = [[NSMutableData alloc] init];
}
- (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data {
// Alternatively, store to a file so you don't run out of memory
[self.responseData appendData:data];
}
#end
Then implement the other NSURLConnection delegate methods to do what you need.
I've written an open source example that has pretty much all features you want, canceling a download is currently only available in code, but it's pretty easy to add a button for that.
I'm using asi-http-request for managing the downloads, and they are displayed in a grid view (AQGridView) instead of a UITableView, but i think you get the idea.
Download progress is managed via KVO.
See PSPDFDownload.m for a start. Download the full demo here
Full disclosure: This demo uses PSPDFKit for faster pdf display. But the Kiosk example is exactly what you need, and you don't need to use PSPDFKit for pdf display. There's even an example code path that uses Apple's QuickLook.
