nsurl

I have created a very simple app to download a text file from my web server. I have this working perfectly with NSURLConnection, but am trying to migrate over to NSURLSession instead. The issue I am having is that none of the delegate methods are being called. My server is password protected so I need to use the basic http authentication to access the file, but when the didReceiveChallenge method is never called. The line of code [getFileTask resume] seems to have no effect on anything. My setup is as follows: @interface ViewController : UIViewController <NSURLSessionDelegate,

I am making two iPad app that communicate with one file and fetches all the data from one file. I search and find this "containerURLForSecurityApplicationGroupIdentifier" we can create group and store in that. I have write the code below. In entitlement file i write <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>com.apple.security.app-sandbox</key> <true/> <key>com.apple.security.application-groups</key> <array> <string>$(TeamIdentifierPrefix)com.xxx.catalogapp

I'm beginning to play around with Core Data and just have a question around storing something like a URL. I've currently got it configured as a transformable which is working fine however I feel that it's probably storing excess data unnecessarily and since it can be easily represented with text I'm wondering whether I should just be storing the absolute URL as a string and instantiating an NSURL object when it's loaded (I suspect this is the case) and if so how should this be implemented? My research so far leads me to think maybe use mogenerator and then just override the property accessors

TLDR When I hard code phone numbers into a URL it opens in watch messages correctly, but when I use a variable string with the numbers typed in exactly the same way inside of it, it doesn't. Example: NSURL(string: "sms:/open?addresses=8888888888,9999999999,3333333333&body=Test") Above code works but below code doesn't: let hardCode = "8888888888,9999999999,3333333333" NSURL(string: "sms:/open?addresses=\(hardCode)&body=Test") FULL DETAILS: I am making a URL from variables to open messages on the Apple Watch with pre-filled contents. I am getting the phone numbers from the contact book and

I know that I can deep link into the Settings page on iOS via UIApplicationOpenSettingsURLString . However, this takes me to a page such as this: Now if I want the user to enable notifications, they have to find Notifications in the list and then enable it. Is there a way to instead directly link them to the Notifications page? (i.e. Going to the same exact page as though they had tapped notifications in the screenshot above.) If not, is there a way to take them to the global notifications iOS Settings page? (See screenshot below for an example) No, there is no way to go to any other page in

I have an NSURL. It is file://localhost/Users/Me/File.xml I want an NSString that is /Users/Me/File.xml Is there some nice function I can use to do this? NSURL path method sounds like it does what you want. 来源： https://stackoverflow.com/questions/3057086/how-to-chop-off-file-from-nsurl

I have to download the database and replace existing one in the sandbox: Here's is the presumable way to do that: DBHelpers *help=[[DBHelpers alloc] init]; NSString *targetPath=[[help DocumentsDirectory] stringByAppendingPathComponent:DATABASE_NAME]; NSLog(@"Target path: %@", targetPath); NSFileManager *fileManager=[NSFileManager defaultManager]; //if([fileManager fileExistsAtPath:targetPath]) //{ // NSLog(@"Exists"); // return; } NSString *sourcePath=[help PathForResource:DATABASE_NAME]; NSLog(@"SourcePath path: %@", sourcePath); NSError *error; NSData *data=[NSData dataWithContentsOfURL:
