I am trying to get the html code of the webpage using following code :-
let url = NSURL(string: "http://www.example.com")
var error: NSError?
let html = NSString(contentsOfURL: url!, encoding: NSUTF8StringEncoding, error: &error)
if (error != nil) {
print("whoops, something went wrong")
} else {
print(html!)
}
But i am getting following error in line number 3 ( let html = ....) :-
Argument labels '(contentsOfURL:, encoding:, error:)' do not match any available overloads
The function is NSString(contentsOfURL url: NSURL, encoding enc: UInt) throws
Your code should look like this:
if let url = NSURL(string: "http://www.example.com") {
do {
let html = try NSString(contentsOfURL: url, encoding: NSUTF8StringEncoding)
print(html)
} catch {
print("whoops, something went wrong")
}
}
For more information, take a look at the new way of handling errors in Swift.
UPDATE
Used with your URL:
if let url = NSURL(string: "http://www.police.gov.bd/career_child.php?id=247%20order%20by%201--") {
do {
let html = try NSString(contentsOfURL: url, encoding: NSUTF8StringEncoding)
print(html)
} catch {
print("whoops, something went wrong")
}
}
UPDATE 2:
To autodetect the encoding see this answer
http://or https://)http://www.police.gov.bd/career_child.php?id=247%20order%20by%201--, without http it is not well formattedNSISOLatin1StringEncoding, not NSISOLatinStringEncoding. When I use the code above with that encoding and your url it works fine. PS: I also added a new edit for autodetecting the encodingUse below code:
if let url = NSURL(string: "http://www.example.com") {
do {
let myHTMLString = try String(contentsOfURL: url, encoding: NSUTF8StringEncoding)
} catch let error as NSError {
print("Error: \(error)")
} catch {
print("failure")
}
}
NSErrorcode management has changed in Swift. You have to makedo/catch: developer.apple.com/library/ios/documentation/Swift/Conceptual/…
