This is how the code looks like right now:
func fetchSalahtimes (){
let url = NSURL(string: "http://irvingmasjid.org/salah2016.php")
let request = NSURLRequest(URL: url!)
let config = NSURLSessionConfiguration.defaultSessionConfiguration()
let session = NSURLSession(configuration: config)
let task = session.dataTaskWithRequest(request, completionHandler: {(data, response, error) in
if data != nil{ // is this how i should do it to check for success/fail/errors?
}
});
// do whatever you need with the task e.g. run
task.resume()
}
I have searched in SO or in google from similar questions, but i could not find something that really suited me. I came this far by searching.
I am trying to grasp how to work with completion handlers. The code is supposed to fetch some json content from the web. And this is where i need help with some questions.
1) If i am going to call this function from another class, how can i retrieve the content that it fetched by using this completion handler?
2) How and where should i proceed to write text to actually get the content? every time i write this to get the JSON content:
if data != nil{
let json = try NSJSONSerialization.JSONObjectWithData(data!, options:.AllowFragments)
let sunrise = json["sunrise"] as! String
print(sunrise)
salahTimes.append(sunrise)
}
I get this error message:
Invalid conversion from throwing function of type '(_, _, _) throws -> ()' to non-throwing function type '(NSData?, NSURLResponse?, NSError?) -> Void'
