I have a problem with using the NSMXLParser.
first of all here is my code:
class ViewController: UIViewController, NSXMLParserDelegate {
override func viewDidLoad() {
super.viewDidLoad()
var url = NSURL(string: "http://placeholder.abc/data.xml")
var xmlParser = NSXMLParser(contentsOfURL: url)
xmlParser.delegate = self
xmlParser.parse()
}
func parser(parser: NSXMLParser, didStartElement elementName: String, namespaceURI: String, qualifiedName qName: String, attributes attributeDict: [NSObject : AnyObject]) {
println(elementName)
}
func parser(parser: NSXMLParser, didEndElement elementName: String, namespaceURI: String, qualifiedName qName: String) {
}
func parser(parser: NSXMLParser, foundCharacters string: String) {
}
Now the problem is: As soon as I implement the didEndElement method my application crashes while executing this code line: xmlParser.parse() with this Error: Thread 1: EXC_BAD_ACCESS (code=1, address=0x0)
When I delete the didEndElement method, the code runs fine. Can someone help me? Thanks!
I'm developing an iOS app since several months so it made its way through all the beta versions of Xcode. The XMLParser part in that app has this signature:
func parser(parser: NSXMLParser!, didEndElement elementName: String!, namespaceURI: String!, qualifiedName qName: String!) {
...
}
This works without errors.
When I remove the exclamation marks, the app crashes with EXC_BAD_ACCESS
All other methods of NSXMLParserDelegate have the same signature: All variables are bound as implicitly unwrapped optionals (all with !)
