Perform POST request in Swift
ios, nsurlconnection, post, swift
Solution
`stringByAddingPercentEscapesUsingEncoding` returns a string instead of an NSData object. According to this answer, you need to use this to convert to an NSData instance:
let data = (anySwiftString as NSString).dataUsingEncoding(NSUTF8StringEncoding)
Problem
I am trying to do something like this: ``` NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:@"http://google.com"]]; request.HTTPMethod = @"POST"; NSString *stringData = @"some data"; NSData *requestBodyData = [stringData dataUsingEncoding:NSUTF8StringEncoding]; request.HTTPBody = requestBodyData; NSURLConnection *conn = [[NSURLConnection alloc] initWithRequest:request delegate:self]; ``` This is what I have so far: ``` var url = NSURL(string: "some url") var request = NSMutableURLRequest(URL: url) request.HTTPMethod = "POST" var dataString = "some data" var requestBodyData: NSData = dataString.stringByAddingPercentEscapesUsingEncoding(NSUTF8StringEncoding) as NSData request.HTTPBody = requestBodyData var connection = NSURLConnection(request: request, delegate: self, startImmediately: false) println("sending request...") connection.start() ``` However, the var requestBodyData: line throws the first stone with "Cannot convert the expression's type NSData to type NSData" Anyone care to weigh in?
