我有一个带有2个按钮的应用程序 macOS ,但它们不是触发器 我已将IBActions连接到按钮
文档
override func windowControllerDidLoadNib(_ windowController: NSWindowController) {
super.windowControllerDidLoadNib(windowController)
// user interface preparation code
guard let context = self.managedObjectContext else { fatalError("context is nil") }
mainObjectContext = context
let mainWindowController = MainWindowController(nibName: NSNib.Name(rawValue: "MainWindowController"), bundle: nil)
customView1.addSubview(mainWindowController.view)
setUpLayoutConstraints(item: mainWindowController.view, toItem: customView1)
}
func setUpLayoutConstraints(item : NSView, toItem: NSView)
{
item.translatesAutoresizingMaskIntoConstraints = false
let sourceListLayoutConstraints = [
NSLayoutConstraint(item: item, attribute: .left, relatedBy: .equal, toItem: toItem, attribute: .left, multiplier: 1, constant: 0),
NSLayoutConstraint(item: item, attribute: .right, relatedBy: .equal, toItem: toItem, attribute: .right, multiplier: 1, constant: 0),
NSLayoutConstraint(item: item, attribute: .top, relatedBy: .equal, toItem: toItem, attribute: .top, multiplier: 1, constant: 0),
NSLayoutConstraint(item: item, attribute: .bottom, relatedBy: .equal, toItem: toItem, attribute: .bottom, multiplier: 1, constant: 0)]
NSLayoutConstraint.activate(sourceListLayoutConstraints)
}
和MainWindowController
类MainWindowController:NSViewController {
@objc var managedObjectContext: NSManagedObjectContext = mainObjectContext
@objc dynamic var customSortDescriptors = [NSSortDescriptor(key: "name", ascending: true, selector: #selector(NSString.localizedStandardCompare(_:)))];
@IBOutlet weak var textFiled: NSTextField!
override func viewDidLoad() {
super.viewDidLoad()
// Do view setup here.
print("hello")
textFiled.stringValue = "hello"
}
@IBAction func actionAddNew(_ sender: Any) {
print("add")
textFiled.stringValue = "add"
}
@IBAction func actionRemove(_ sender: Any) {
print("remove")
textFiled.stringValue = "remove"
}
}
我已经尝试过,我不知道该怎么做
我当然忘记了什么 在另一个应用程序NSPersistentDocument中没有问题
