I'm trying to add an accessory view to an NSAlert with a button on it. When you click on the button in the alert, it should print some text to the console.
The problem is that the application crashes when I don't write the name of the variable that contains the NSViewController of the accessory view, into the completionHandler of the NSAlert. I don't understand why it crashes, the only error I get is this:
EXC_BAD_ACCESS(code=1, address=0x40dedeadbec0)
I don't get it. I don't even use the variable but when it is there, everything works fine. If I comment it, the app crashes.
I got this error in a bigger project and I struggled a lot to find out this was the problem. So I decided to test it in a new empty project and it does the same.
This is my AppDelegate file :
import Cocoa
@NSApplicationMain
class AppDelegate: NSObject, NSApplicationDelegate {
@IBOutlet weak var window: NSWindow!
func applicationDidFinishLaunching(_ aNotification: Notification) {
// Insert code here to initialize your application
}
func applicationWillTerminate(_ aNotification: Notification) {
// Insert code here to tear down your application
}
@IBAction func add(_ sender: NSObject) {
let a = NSAlert()
let cont = Test()
a.accessoryView = cont.view
a.beginSheetModal(for: window, completionHandler: {(modalResponse: NSModalResponse) -> Void in
//When you comment the line underneath, it doesn't work anymore, why ?
cont
})
}
}
This is my Test class file : import Cocoa
class Test: NSViewController {
override func viewDidLoad() {
super.viewDidLoad()
// Do view setup here.
}
@IBAction func some(sender: NSButton) {
print("something")
}
}
Does anyone know why it behaves like this and how to fix it ?
