You should use relative URLs to store references to files. The absolute URL is likely to change after an app update Files Saved During App Updates When a user downloads an app update, iTunes installs the update in a new app directory. It then moves the user’s data files from the old installation over to … Read more
+URLWithString: produces an NSURL that represents the string as given. So the string might be @”http://www.google.com” and the URL represents http://www.google.com. +fileURLWithPath: takes a path, not a URL, and produces an NSURL that represents the path using a file:// URL. So if you give it /foo/bar/baz the URL would represent file:///foo/bar/baz. You can of course … Read more
Disclaimer : Since this is getting quite a lot of views, I just want to remind everyone that this answer here is synchronous, and will block your app if you do it on the main thread. You should always do this asynchronously (in a background thread), but the question asked for a synchronous method, so … Read more
Swift 3 or later import Cocoa let url = URL(string: “https://www.google.com”)! if NSWorkspace.shared.open(url) { print(“default browser was successfully opened”) }
You need to escape the non-ASCII characters in your hardcoded URL as well: //localisationName is a arbitrary string here NSString* webName = [localisationName stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]; NSString* stringURL = [NSString stringWithFormat:@”http://maps.google.com/maps/geo?q=%@,Montréal,Communauté-Urbaine-de-Montréal,Québec,Canadae&output=csv&oe=utf8&sensor=false”, webName]; NSString* webStringURL = [stringURL stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]; NSURL* url = [NSURL URLWithString:webStringURL]; You can probably remove the escaping of the localisationName since it will be handled by … Read more
All you need is URLComponents (or NSURLComponents in Obj-C). The basic idea is to create a bunch of query items for your id’s. Here’s code you can paste into a playground: import Foundation import XCPlayground let queryItems = [URLQueryItem(name: “id”, value: “1”), URLQueryItem(name: “id”, value: “2”)] var urlComps = URLComponents(string: “www.apple.com/help”)! urlComps.queryItems = queryItems let … Read more
Write like this. Handle completionHandler UIApplication *application = [UIApplication sharedApplication]; NSURL *URL = [NSURL URLWithString:@”http://www.google.com”]; [application openURL:URL options:@{} completionHandler:^(BOOL success) { if (success) { NSLog(@”Opened url”); } }]; Without handling completionHandler [application openURL:URL options:@{} completionHandler:nil]; Swift Equivalent:- open(_:options:completionHandler:) UIApplication.shared.open(url)
This isn’t exactly the third level, mind you. An URL is split like that way: the protocol or scheme (here, http) the :// delimiter the username and the password (here there isn’t any, but it could be username:password@hostname) the host name (here, digg.com) the port (that would be :80 after the domain name for instance) … Read more
You need to escape the special characters to make it work properly. Something like: [NSURL URLWithString:[googlSearchString stringByAddingPercentEscapesUsingEncoding: NSUTF8StringEncoding]];
