nsurl

问题 I need to make a phone call from the app, so far it's working. The number consists of two numbers: phone number, and pass code followed by hashtag. But some users need to put double hashtag in the end of the number, and that crashes the app when it's calling that URL at once: UIApplication.sharedApplication().openURL(NSURL (string: "tel//:1111111,,222##")) With single hashtag it's working, and it is possible to press hashtag on the keyboard after device has dialed already. I tried to append

问题 I am on OSX, Objective-C. I have a path/NSURL like /Users/xxx/Desktop/image2.png But i pass it to a third party application that excpects finder pathes like Harddisk:Users:Desktop:image2.png Is there any method (i can't find) to convert pathes like that or get them out of an NSURL (if possible without string modifying)? In AppleScript it is return POSIX file "/Users/xxx/Desktop/image2.png" --> Harddisk:Users:xxx:Desktop:image2.png EDIT : This is pretty much the same: Cocoa path string

问题 - bookmarkDataWithOptions:includingResourceValuesForKeys:relativeToURL:error: Documentation states: This method returns bookmark data that can later be resolved into a URL object for a file even if the user moves or renames it (if the volume format on which the file resides supports doing so). My question is, how can I query if a volume supports this feature? From trial and error it seems only (internal?) hard drives support it, but I am looking for some kind of sure test like a

问题 I want to open the native dialer app and allow the user to enter the phone number there. The reason why i want this is because in my app the user needs to use USSD codes in order to make calls, but using the code bellow nothing happens (nothing is started) NSString *phoneNumber = [@"tel://" stringByAppendingString:number]; [[UIApplication sharedApplication] openURL:[NSURL URLWithString:phoneNumber]]; I read here (StackOverflow) that making calls from your app that contain * and # are

问题 I am confused by Apple's documentation about the NSURL class. In NSURL, they say the following: NSURL understands URLs in style of RFC 1808, 1738 und 2732 NSURL understands URIs in style of RFC 2396 Also they say that the RFC 2396 URI are paths. Now what's the difference here? Isn't a path also an URL? I mean, it's an location or not? 回答1: Both URLs and URIs identify resources (which are anything). However, a URL is the term used for an identifier that specifies how to locate the resource.

问题 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

问题 I think I don't understand the concept of "baseURL". This: NSLog(@"BASE URL: %@ %@", [NSURL URLWithString:@"http://www.google.es"], [[NSURL URLWithString:@"http://www.google.es"] baseURL]); Prints this: BASE URL: http://www.google.es (null) And of course, in the Apple docs I read this: Return Value The base URL of the receiver. If the receiver is an absolute URL, returns nil. I'd like to get from this example URL: https://www.google.es/search?q=uiviewcontroller&aq=f&oq=uiviewcontroller
