nsurl

I need to pass text string up to 20Kb (one NSURLQueryItem value) from one iOS app to another using schemes. I was able to pass not such long URL between the apps. What is max NSURL length supported? Does it depend on iOS version? Is there any better approach to send text long string? NSURL can easily handle 20Kb. The implementation limitation is around 2Gb ( INT_MAX ) for the URL string. The limitations you'll run into first with large URLs are memory and time. You'll run out of memory for the allocations at some point (For 32-bit executables, the limitation is a little over 1.1GB when your

I have an UIImagePickerController and I would like to save a selected image to my app. I can do that easy by getting the current UIImage and save it (by creating a file) but I would prefer to directly copy the file from Library to my folder. So now I have an URL of the selected image : UIImagePickerControllerReferenceURL which return a specific pattern "assets-library". I tried to copy an image from this kind of URL to a path but without success. Is there a way to success on what I would like to do ? Thanks !

I'm loading a lot of image paths into a NSURL. The images are in a folder ordered from 1.PNG, 2.PNG, 3.PNG to 1500.PNG. When I trie to load them: let imagePath = path + "/images" let url = NSURL(fileURLWithPath: imagePath) print(url) let fileManager = NSFileManager.defaultManager() let properties = [NSURLLocalizedLabelKey, NSURLCreationDateKey, NSURLLocalizedTypeDescriptionKey] do { imageURLs = try fileManager.contentsOfDirectoryAtURL(url, includingPropertiesForKeys: properties, options:NSDirectoryEnumerationOptions.SkipsHiddenFiles) } catch let error1 as NSError { print(error1.description) }

I use this code to load a UIImage from a URL : NSURL *imageURL = [NSURL URLWithString:@"http://testwebsite.com/image.png"]; NSData *imageData = [[NSData alloc] initWithContentsOfURL:imageURL]; imageView.image = [UIImage imageWithData: imageData]; but I'm stuck at a URL that looks like this one : http://www.testwebsite.com/getFile?userID=123 this works fine in the browser but returns nil in the imageData variable above. how can I load the image from such an obscured URL (i.e. from a URL that does not show off the file name but rather redirects to the image file) ? thank you in advance. for some

I want to upload array of images, how should I append array to NSMutableData . here is my code func createBodyWithParametersMulti(parameters: [String: String]?, filePathKey: String?, imageDataKey: [NSData?], boundary: String) -> NSData { let body = NSMutableData(); if parameters != nil { for (key, value) in parameters! { body.appendString("--\(boundary)\r\n") body.appendString("Content-Disposition: form-data; name=\"\(key)\"\r\n\r\n") body.appendString("\(value)\r\n") } } if(imageDataKey.count != 0){ let filename=filePathKey as! String // let mimetype = "image/jpeg" body.appendString("--\

I have an iOS application which will submit a username and password to a website and to retrieve the HTML code of the webpage which loads after pressing 'Sign in': https://grades.bsd405.org/Pinnacle/Gradebook/Logon.aspx ?. The form data fields are the following: __LASTFOCUS, __EVENTTARGET, __EVENTARGUMENT, __VIEWSTATE, __EVENTVALIDATION, ctl00$ContentPlaceHolder$Username, ctl00$ContentPlaceHolder$Password, ctl00$ContentPlaceHolder$lstDomains, ctl00$ContentPlaceHolder$LogonButton, PageUniqueId This is the code that I have so far: NSURL * url = [NSURL URLWithString:@" https://grades.bsd405.org

I have some images on my server, named with special characters (å,ä,ö). I can't figure out how to convert the NSUrl to get them: NSString *urlString = [NSString stringWithFormat: @".../Images/%@Image.png", playerName]; NSURL *url = [NSURL URLWithString: [urlString stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]]; NSLog(@"url:%@", url); //Get the image and assign it to the player NSData *imageData = [NSData dataWithContentsOfURL:url]; UIImage *image = [UIImage imageWithData:imageData]; The log in the above example (if "playerName" = åäö): .../Images/%C3%A5%C3%A4%C3%B6Image.png
