How to prepare an NSURL from an NSString continaing international characters?

由 我们两清 提交于 2019-11-27 07:08:01
问题 I have to access a web server using a GET with international characters (Hebrew in my case but could be anything). So I make an NSString just fine but [NSURL URLWithString:urlString]; // returns nil. I realize I probably have to convert the international characters to percent codes. Is there a built in method in Objective-c to do so? 回答1: Yes there is, you need -stringByAddingPercentEscapesUsingEncoding: method: [NSURL URLWithString:[string stringByAddingPercentEscapesUsingEncoding

Can I somehow do a synchronous HTTP request via NSURLSession in Swift? I can do an asynchronous request via the following code: if let url = NSURL(string: "https://2ch.hk/b/threads.json") { let task = NSURLSession.sharedSession().dataTaskWithURL(url) { (data, response, error) in var jsonError: NSError? let jsonDict = NSJSONSerialization.JSONObjectWithData(data, options: nil, error: &jsonError) as [String: AnyObject] if jsonError != nil { return } // ... } task.resume() } But what about synchronous request? Thanks in advance. You can use this NSURLSession extension to add a synchronous method:

问题 Can someone confirm that -checkResourceIsReachableAndReturnError: method of NSURL is working as expected. I have tried using it for known URLs and it is always returning NO . I am using XCode's iPhone Simulator 4.1. Thank you. 回答1: According to NSURL Class Reference Returns whether the resource pointed to by a file URL can be reached. ... Discussion This method is unimplemented in iOS, so it performs no operation So it only works for file URLs (which your URL probably isn't) and it only works

NSURL URLWithString: is null with non-english accented characters

由 隐身守侯 提交于 2019-11-27 00:36:52
I have the following string... NSString *googleSearchString = @"http://www.google.com/search?q=lyrics+%22Tænder+På+Dig%22+%22Jakob+Sveistrup%22"; Notice that it has some accented characters. When I try to turn that into a url the returned url is null... [NSURL URLWithString:googleSearchString]; So normally the url works except when there are accented non-english characters in the string. Any help on how to handle that? You need to escape the special characters to make it work properly. Something like: [NSURL URLWithString:[googlSearchString stringByAddingPercentEscapesUsingEncoding:

Get parts of a NSURL in objective-c

I have an NSString with the value of http://digg.com/news/business/24hr How can I get everything before the 3rd level? http://digg.com/news/ 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) the path (here, /news/business/24hr ) the parameter string (anything that follows a semicolon) the query string (that would be if you
