I am building a macOS menubar app in Swift, using an NSStatusItem, which opens an NSPopover when the NSStatusItem's button is clicked.
How can I also give the NSPopover focus? Currently, the user needs to click on the popover to focus it, but I want to grab focus programmatically.
Thanks in Advance
The solution is to call makeKey() on the owning window.
This can be done either from the main NSApplicationDelegate, e.g.
func applicationDidFinishLaunching(_ aNotification: Notification) {
// Other setup
popover.contentViewController?.view.window?.makeKey()
}
Or from the relevant NSViewController, e.g.
override func viewDidAppear() {
super.viewDidAppear()
view.window?.makeKey()
}
Documentation is here
How do I create outlets for my keys in a custom keyboard to switch from letters to numbers and symbols? I am trying to create a custom keyboard and I don't know how to create outlets for my keys to switch back and forth from letters to numerals and symbols.
So, I gather from your comment, that this is what you are looking for. The type of keyboard input, is determined by setting the 'keyboardType' property of the keyboard's delegate. If you want to switch and update a view, I think you'll have to dismiss the keyboard and recall it. I find this unsafe, and would highly suggest using a normal keyboard (which has all the characters you need), trusting your user, and sanitizing the input. But the following does work, if you must. In the following, 'txtField' is a UITextField with the UIViewController set as its delegate, the IBAction is wired to a UIButton, and 'isNumbers' is a Bool property of the UIViewController.
#IBAction func switchKeyboards(_ sender: Any) {
if isNumbers {
txtField.keyboardType = UIKeyboardType.alphabet
isNumbers = false
} else {
txtField.keyboardType = UIKeyboardType.numberPad
isNumbers = true
}
txtField.resignFirstResponder()
txtField.becomeFirstResponder()
}
I'm doing custom keyboard thing on Xcode using swift.
My problem is on KeyboardViewController.swift file.
I have no idea how to use next keyboard button :e
wanted to connect #IBOutlet var nextKeyboardButton: UIButton! to the button that i created but it is not working ..
When your "Next Keyboard" button tapped, call
advanceToNextInputMode()
in your KeyboardViewController.
I am using this function to achieve this but with the iphone keyboard. Maybe it could help
func textFieldShouldReturn(textField: UITextField) -> Bool {
let nextTage=textField.tag+1;
// Try to find next responder
let nextResponder=textField.superview?.viewWithTag(nextTage) as UIResponder!
if (nextResponder != nil){
// Found next responder, so set it.
nextResponder?.becomeFirstResponder()
}
else
{
// Not found, so remove keyboard
textField.resignFirstResponder()
}
return false // We do not want UITextField to insert line-breaks.
}
I am trying to display a second window after a button click:
var winJ:WinJo // other window NSViewController
#IBAction func BtnNewWin(sender: AnyObject) {
winJ = WinJo()
winJ.showWindow(self)
}
This works fine but I want the new window to be modal. I accomplished this with the Xcode designer but I couldn't figure out how to do this in code.
After I was pointed in the right direction I found the solution to my problem:
NSApp.runModalForWindow(winJ.window!)
Where NSApp is actually the instance of NSApplication.
And very important in the second window:
func windowWillClose(notification: NSNotification) {
NSApp.stopModal()
}
Otherwise your main window will be blocked after closing the second.
I put a numeric keypad in my app for inputing numbers into a text view, but in order to input numbers I have to click on the text view. Once I do so, the regular keyboard comes up, which I don't want.
How can I disable the keyboard altogether? Any help is greatly appreciated.
The UITextField's inputView property is nil by default, which means the standard keyboard gets displayed.
If you assign it a custom input view, or just a dummy view then the keyboard will not appear, but the blinking cursor will still appear:
UIView* dummyView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 1, 1)];
myTextField.inputView = dummyView; // Hide keyboard, but show blinking cursor
If you want to hide both the keyboard and the blinking cursor then use this approach:
-(BOOL)textFieldShouldBeginEditing:(UITextField *)textField {
return NO; // Hide both keyboard and blinking cursor.
}
For Swift 2.x, 3.x, 4.x, 5.x
textField.inputView = UIView()
does the trick
If it's a UITextField, you can set it's enabled property to NO.
If it's a UITextView, you can implement -textViewShouldBeginEditing: in its delegate to return NO, so that it'll never start editing. Or you can subclass it and override -canBecomeFirstResponder to return NO. Or you could take advantage of its editing behavior and put your numeric buttons into a view which you use as the text view's inputView. This is supposed to cause the buttons to be displayed when the text view is edited. That may or may not be what you want.
Depending on how you have your existing buttons working this could break them, but you could prevent the keyboard from showing up setting the textView's editable property to NO
myTextView.editable = NO
I have the same problem when had 2 textfields on the same view. My purpose was to show a default keyboard for one textfield and hide for second and show instead a dropdown list.
- (BOOL)textFieldShouldBeginEditing:(UITextField *)textField
method simply did not work as I expected for 2 textfields , the only workaround I found was
UIView* dummyView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 1, 1)];
myTextField.inputView = dummyView;
myTextField.inputAccessoryView = dummyView;
myTextField.tintColor = myTextField.backgroundColor; //to hide a blinking cursor
This will totally hide the keyboard for a target textField (DropDownList in my case) and show a default one when user switches to the 2nd textfield (Account number on my screenshot)
There is a simple hack to it. Place a empty button
(No Text) above the keyboard and have a action Event assign to it. This will stop keyboard coming up and you can perform any action you want in the handle for the button click
To disable UITextField keyboard:
Go to Main.Storyboard
Click on the UITextField to select it
Show the Attributes inspector
Uncheck the User Interaction Enabled
To disable UITextView keyboard:
Go to Main.Storyboard
Click on the UITextView to select it
Show the Attributes inspector
Uncheck the Editable Behavior
I used the keyboardWillShow Notification and textField.endEditing(true):
lazy var myTextField: UITextField = {
let textField = UITextField()
// ....
return textField
}()
override func viewDidLoad() {
super.viewDidLoad()
NotificationCenter.default.addObserver(self, selector: #selector(keyboardWillShow(_:)), name: UIResponder.keyboardWillShowNotification, object: nil)
}
#objc func keyboardWillShow(_ notification: Notification) {
myTextField.endEditing(true)
// if using a textView >>> myTextView.endEditing(true) <<<
}
private void TxtExpiry_EditingDidBegin(object sender, EventArgs e)
{
((UITextField)sender).ResignFirstResponder();
}
In C# this worked for me, I don't use the storyboard.
In Xcode 8.2 you can do it easily by unchecking state "enabled" option.
Click on the textField you want to be uneditable
Go to attirube inspector on right side
Uncheck "enabled" for State
Or if you want to do it via code. You can simply create an #IBOutlet of this text field, give it a name and then use this variable name in the viewDidLoad func (or any custom one if you intent to) like this (in swift 3.0.1):
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
myTextField.isEditable = false
}
