I am using a file to handle my calls to my APIs which looks like this:
import UIKit
protocol APIControllerProtocol {
func JSONAPIResults(results: NSArray)
}
class APIController: NSObject {
var delegate:APIControllerProtocol?
func GetAPIResultsAsync(urlString:String, elementName:String) {
//The Url that will be called
var url = NSURL.URLWithString(urlString)
//Create a request
var request: NSURLRequest = NSURLRequest(URL: url)
//Create a queue to hold the call
var queue: NSOperationQueue = NSOperationQueue()
// Sending Asynchronous request using NSURLConnection
NSURLConnection.sendAsynchronousRequest(request, queue: queue, completionHandler:{(response:NSURLResponse!, responseData:NSData!, error: NSError!) ->Void in
var error: AutoreleasingUnsafeMutablePointer<NSError?> = nil
//Serialize the JSON result into a dictionary
let jsonResult: NSDictionary! = NSJSONSerialization.JSONObjectWithData(responseData, options:NSJSONReadingOptions.MutableContainers, error: error) as? NSDictionary
//If there is a result add the data into an array
if jsonResult.count>0 && jsonResult["\(elementName)"]?.count > 0 {
var results: NSArray = jsonResult["\(elementName)"] as NSArray
//Use the completion handler to pass the results
self.delegate?.JSONAPIResults(results)
} else {
println(error)
}
})
}
}
I am calling it using something similar to this:
var APIBaseUrl: String = "http://***.se/**/**.php"
var urlString:String = "\(APIBaseUrl)"
self.api.delegate = self
api.GetAPIResultsAsync(urlString, elementName:"groupActivities")
This have recently worked great but now my app crashes and i get this row in the APIController highlighted:
let jsonResult: NSDictionary! = NSJSONSerialization.JSONObjectWithData(responseData, options:NSJSONReadingOptions.MutableContainers, error: error) as? NSDictionary
The only thing that i can think of that have changed is that i switched from mobile 4G internet to my WiFi.
In the log i get: fatal error: unexpectedly found nil while unwrapping an Optional value
The highlight says: Thread 5: EXC_BAD_INSTRUCTION (code=EXC_I386_INVOP, subcode=0x0)
This occurs regardless of what API i'm calling. I'm running Xcode 6.0.1 and have not done any recent updates.
Cheers!
