Can Anyone help me, i'm having problem with UIMenucontroller.In here, i have to use two menucontroller in single viewcontroller.
For First menu only "paste",for other menu "copy","select","select all" When i'm using shared menucontroller it affects the other menu.
My code for first menu is as follows:
override func canBecomeFirstResponder() -> Bool
{
return true
}
override func canPerformAction(action: Selector, withSender sender: AnyObject?) -> Bool
{
//actions
}
UIMenuController.sharedMenuController().menuItems = nil
let Select: UIMenuItem = UIMenuItem(title: "Select", action: Selector("Select"))
let SelectAll: UIMenuItem = UIMenuItem(title: "SelectAll", action: Selector("SelectAll"))
let Copy: UIMenuItem = UIMenuItem(title: "Copy", action: Selector("Copy"))
let menu: UIMenuController = UIMenuController.sharedMenuController()
menu.menuItems = [Select,SelectAll,Copy]
menu.setTargetRect(cell.frame, inView: cell.superview!)
menu.setMenuVisible(true, animated: true)
and my second menu is:
UIMenuController.sharedMenuController().menuVisible = false
let paste: UIMenuItem = UIMenuItem(title: "Paste", action: Selector("paste"))
let menu: UIMenuController = UIMenuController.sharedMenuController()
menu.menuItems = [paste]
menu.setTargetRect(message_Textfield.frame, inView: message_Textfield.superview!)
menu.setMenuVisible(true, animated: true)
Error:
In here,in second menu contains unwanted things as [Select,SelectAll,Copy] with [Paste].
How can i resolve this,thanks in advance
You should override canPerformAction in a UITextField subclass to disable the item you don't want, then assign each uitextfield you created to the subclass.
For example, disable paste menu item in uimenucontroller：
class CustomTextField: UITextField {
override func canPerformAction(action: Selector, withSender sender: AnyObject?) -> Bool {
if action == "paste:" {
return false
}
return super.canPerformAction(action, withSender: sender)
}
}
Usage:
let message_Textfield = CustomTextField()
Now paste menu item will be disabled for message_Textfield
Hi Thanks for your answer,But i found solution as follows:
override func canPerformAction(action: Selector, withSender sender: AnyObject?) -> Bool
{
if(MenuBool == true){
if action == Selector("Copy") || action == Selector("star") || action == Selector("info") || action == Selector("forward") || action == Selector("Delete")
{
print("UIMenuController====>CellMenu")
UIMenuController.sharedMenuController().menuVisible = false
return true
}
print("UIMenuController====>Defaultmenu1")
return false
}else if MenuBool == false
{
print("UIMenuController====>Defaultmenu2")
return false
}else{
print("UIMenuController====>DefaultmenuElse")
return false
}
}
In,this manner working fine.

I'm trying to remove the items Look Up & Share... from the UIMenuController. How would I specifically remove the two and keep my custom one. Here is what I've achieved so far:
override func viewDidAppear(_ animated: Bool) {
super.viewDidAppear(animated)
// add two custom menu items to the context menu of UIWebView (assuming in contenteditable mode)
let menuItem1 = UIMenuItem(title: "My Button", action: #selector(myButtonSel))
UIMenuController.shared.menuItems = [menuItem1]
}
Here is the canPerformAction I have:
override func canPerformAction(_ action: Selector, withSender sender: Any?) -> Bool {
//let shareSelector: Selector = NSSelectorFromString("_share:")
if webView?.superview != nil {
if action == #selector(myButtonSel){
return true
}
}
return super.canPerformAction(action, withSender: sender)
}
Also for some odd reason, when I try to remove all the default items and keep only my custom, it does not work. Here is the code I attempted for that:
override func canPerformAction(_ action: Selector, withSender sender: Any?) -> Bool {
//let shareSelector: Selector = NSSelectorFromString("_share:")
if webView?.superview != nil {
if action == #selector(myButtonSel){
return true
}
else {
return false
}
}
return super.canPerformAction(action, withSender: sender)
}
Even when I try to remove all of the other items and keep my custom, I'm not able to do so. All I'm able to do is add my custom item.
I tried this but it worked for my by subclassing the WebView and overriding canPerformAction method, inside which I manually removed the default options.
override func canPerformAction(_ action: Selector, withSender sender: AnyObject?) -> Bool {
if action == #selector(cut(_:)) {
return false
}
if action == #selector(paste(_:)) {
return false
}
if action == #selector(select(_:)) {
return false
}
if action == #selector(selectAll(_:)) {
return false
}
...
return super.canPerformAction(action, withSender: sender)
}
I referred to this answer by Ike10 and it had worked for me. Give it a shot.
Objective C version of removing default items from UIMenuController. The default items are part of UIResponderStandardEditActions! For removing default items make sure to create a subclasss of UITextField or UITextView for the functionality to work otherwise in UiViewController class it will not work.
#import "CustomTextField.h"
#implementation CustomTextField
- (BOOL)canPerformAction:(SEL)action withSender:(id)sender
{
if (action == #selector(captureTextFromCamera:) ||
action == #selector(delete:) ||
action == #selector(cut:) ||
[NSStringFromSelector(action) isEqualToString:#"_promptForReplace:"] ||
[NSStringFromSelector(action) isEqualToString:#"_transliterateChinese:"] ||
[NSStringFromSelector(action) isEqualToString:#"_insertDrawing:"] ||
[NSStringFromSelector(action) isEqualToString:#"_lookup:"] ||
[NSStringFromSelector(action) isEqualToString:#"_define:"] ||
[NSStringFromSelector(action) isEqualToString:#"_translate:"] ||
[NSStringFromSelector(action) isEqualToString:#"_addShortcut:"] ||
[NSStringFromSelector(action) isEqualToString:#"_accessibilitySpeak:"] ||
[NSStringFromSelector(action) isEqualToString:#"_accessibilitySpeakLanguageSelection:"] ||
[NSStringFromSelector(action) isEqualToString:#"_share:"] )
{
return false;
}
NSLog(#"OPtion :- %#",NSStringFromSelector(action));
return [super canPerformAction:action withSender:sender];
}
#end
The default available options are below which you want to disable.
cut:
copy:
paste:
delete:
_promptForReplace:
_transliterateChinese:
_insertDrawing:
captureTextFromCamera:
_showTextStyleOptions:
_lookup:
_define:
_translate:
_addShortcut:
_accessibilitySpeak:
_accessibilitySpeakLanguageSelection:
_accessibilityPauseSpeaking:
_share:

For swift users please convert it . It is easy to convert.
I show a UIMenuController in a uiviewconroller in this way:
in my class:
override open func canBecomeFirstResponder() -> Bool {
return true
}
open override func canPerformAction(_ action: Selector, withSender sender: Any) -> Bool {
//here I check for my custom action, else return false
return false
}
then to show I use:
//Make this as first responder
self.becomeFirstResponder()
///Build menu
let menu = UIMenuController.shared
///Set item and anchor point, and showit
menu.menuItems = itemsToAdd
menu.setTargetRect(CGRect(x: 0, y: 5, width: bubbleNode.view.bounds.size.width, height: bubbleNode.view.bounds.size.height), in: bubbleImageNode.view)
menu.setMenuVisible(true, animated: true)
the problem is that in a device I show my custom items, but also: "Spell, speak, speck sentence, ecc..." how can I disable it?
override canPerformAction and handle it for each specific action. It working perfectly for me.
override func canPerformAction(_ action: Selector, withSender sender: Any?) -> Bool {
var canPerform = super.canPerformAction(action, withSender: sender)
if (action == "your action to restrict") {
canPerform = false
}
return canPerform
}
Ok, the problem is "Accessibility" option "speak selection" in my device, if I disabled it, I see only the custom items, but in other app i see only custom items with this option enabled!
class TextViewWithCopyAction: UITextView {
override func canPerformAction(_ action: Selector, withSender sender: Any?) -> Bool {
if action == #selector(copy(_:)){
return true
} else {
return false
}
}
}
to use it:
let textView: TextViewWithCopyAction = {
let textView = TextViewWithCopyAction()
textView.backgroundColor = .white
return textView
}()
If you see speak option in UIMenuController that is from device go to:
Setting->Accessibility->Speech->Speech
Select and disable it. Automatically Speak option will get removed from menu.
I am trying to show the ios copy button on a view and handle the click on a custom function. I tried to display the button with this code but nothing is appearing.
let menu = UIMenuController.shared
if !menu.isMenuVisible {
menu.setTargetRect(paragraphTableViewCell.bounds, in: paragraphTableViewCell)
menu.setMenuVisible(true, animated: true)
}
EDIT:
I got this errors
You need to call canBecomeFirstResponder In your class.
And override canPerformAction then add your appropriate option as UIMenuItem
func canBecomeFirstResponder() -> Bool {
return true
}
override func canPerformAction(_ action: Selector, withSender sender: Any) -> Bool {
if action == #selector(self.cut) {
return false
}
else if action == #selector(self.copy) {
return true
}
else if action == #selector(self.paste) {
return false
}
else if action == #selector(self.select) || action == #selector(self.selectAll) {
return true
}
else {
return super.canPerformAction(action, withSender: sender)
}
}
override func copy(_ sender: Any?) {
}
Finally you should pass UIView object
menu.setTargetRect(paragraphTableViewCell.bounds, in: paragraphTableViewCell.contentView)
Because its required
- (void)setTargetRect:(CGRect)targetRect inView:(UIView *)targetView;
Im trying to create a intractable pop over similar to how apples "copy", "paste". Im not sure how to do it.
Is there a 3rd party lib or is it a native component ?
If it helps anyone, the keyword to look for is "UIMenuController"
I finally managed to solve this by implementing a custom UITableViewCell
override func setSelected(_ selected: Bool, animated: Bool) {
super.setSelected(selected, animated: animated)
let showPasswordItem = UIMenuItem(title: "Show Password", action: #selector(showPass(_:)))
let copyUserNameItem = UIMenuItem(title: "Copy Username", action: #selector(copyUsername(_:)))
let copyPasswordItem = UIMenuItem(title: "Copy Password", action: #selector(copyPass(_:)))
self.isPasswordShowing = !self.password.isSecureTextEntry
UIMenuController.shared.menuItems?.removeAll()
UIMenuController.shared.menuItems = [copyPasswordItem,copyUserNameItem,showPasswordItem,hidePasswordItem]
UIMenuController.shared.update()
if selected {
self.becomeFirstResponder()
let menu = UIMenuController.shared
menu.setTargetRect(self.contentView.frame, in: self.contentView.superview!)
menu.setMenuVisible(true, animated: true)
}
}
override func canPerformAction(_ action: Selector, withSender sender: Any?) -> Bool {
return action == #selector(showPass(_:)) || action == #selector(copyUsername(_:)) || action == #selector(copyPass(_:))
}
override var canBecomeFirstResponder : Bool {
return true
}
func showPass(_ send:AnyObject){
self.password.isSecureTextEntry = false
self.isPasswordShowing = true
}
func copyUsername(_ send:AnyObject){
UIPasteboard.general.string = self.username.text
}
func copyPass(_ send:AnyObject){
UIPasteboard.general.string = self.password.text
}
func hidePass(_ send:AnyObject){
self.password.isSecureTextEntry = true
self.isPasswordShowing = false
}
I managed to subclass UITextView and disabled the "Define" contextual menu item.
class TextViewer: UITextView {
// Overide, disable the "Define" contextual menu item
override func canPerformAction(action: Selector, withSender sender: AnyObject?) -> Bool {
if action == "_define:" {
return false;
}
return super.canPerformAction(action, withSender: sender)
}
}
But now, how do I add a different/custom menu item to take its place? I was guessing it might be something like this, but it's not quite right.
var menuController = UIMenuController.sharedMenuController()
var customMenuItem = UIMenuItem(title: "Lookup", action: "lookupWord")
menuController.menuItems?.append(customMenuItem)
Thanks for any help you folks can give me. ;-)
Nevermind:
let mnuController = UIMenuController.sharedMenuController()
let lookupMenu = UIMenuItem(title: "Tshawb", action: "tshawb")
mnuController.menuItems = NSArray(array: [lookupMenu])
// This makes the menu item visible.
mnuController.setMenuVisible(true, animated: true)
