How can I show the keyboard when my popover shows up?
The popover is UIViewController that I call from a popoverController.
The popover has an UITextField and when the popover is displayed, the keyboard need to show up too and the cursor go to the UITextfield.
I tried to put the becomeFirstResponder under viewDidLoad or viewWillLoad, and not work.
[userValue becomeFirstResponder];
What I miss?
That's all folks. Thanks.
You need to make the textField the first responder, not the popover itself. Just because you make an object the first responder, doesn't mean it will show the keyboard. It needs to be an object with text entry properties, like a UITextField, to display the keyboard.
- (void)viewDidAppear:(BOOL)animated{
[_textField becomeFirstResponder];
[super viewDidAppear:animated];
}
You can call the method above if you want that particular textField to be the first responder, with keyboard, each time the popover is displayed. Remember, this method is called AFTER the popover is loaded.
Hope this helps.
Assign the first responder in the viewWillAppear method.
i think u didn't set the textfield delegates to self and trying putting breakpoints and check what is happening ,is it even going to textfield delegates or not.

My ultimate goal is to have an NSTextField selected by default allowing the user to start typing without clicking on the text field first.
I have a view controlled by a NSViewController. The view contains several text fields. The NSView and NSWindow are both custom subclasses. The text field is not subclassed. Just a standard NSTextField.
Inside awakeFromNIB for the view controller I have the code:
[[[NSApplication sharedApplication] mainWindow] makeFirstResponder:firstBox];
NSLog(#"%#",NSStringFromClass([[[[NSApplication sharedApplication] mainWindow] firstResponder] class]));
The text field gets a focus ring around it, and the NSLog prints that the first responder is an NSTextField but I still have to click inside the text field before I can begin typing.
What could cause the field to be the first responder but not editable? Is there a better method I should be calling makeFirstResponder from?
I found a potentially useful hint on CocoaDev.com, try doing this:
[[[NSApplication sharedApplication] mainWindow]
performSelector: #selector(makeFirstResponder:)
withObject: firstBox
afterDelay:0.0];
I have a ConfigureViewController that contains some UIButtons and a UITextField * MyTextField. Each of the buttons, when pressed, brings up a dialog-style viewcontroller using presentViewController:animated:completion:. However, if I tap one of those buttons while editing the text field, when i close the dialog and return to the original screen, i am unable to return focus to or type in the text field.
This is the method that is invoked when the button is tapped.
-(void)AdvancedInfoButtonPressed :(id)sender
{
AdvancedInfoPopViewController *myAdvancedInfoViewController = [[AdvancedInfoPopViewController alloc] init];
[myAdvancedInfoViewController setDelegateAndDevice :self :Current_Device];
myAdvancedInfoViewController.modalPresentationStyle = UIModalPresentationFormSheet;
[self presentViewController :myAdvancedInfoViewController animated :NO completion :nil];
}
Without explicitly removing focus from MyTextField, presenting the AdvancedInfoViewController does dismiss the keyboard automatically.
I suspect the problem is that MyTextField still thinks it has focus (even though the keyboard and blinking cursor have disappeared) and so does not allow itself to become the first responder again. Along these lines, I have found that if i add [MyTextField resignFirstResponder] before presenting the dialog viewcontroller, the problem goes away.
However, this does not seem like a very good solution because it means having to remember to resign this textfield (or any other text fields) as the first responder in several places (leading to code that is difficult to maintain). My question is: are there any events i can hook into either when ConfigureViewController is about to be partially obscured by AdvancedInfoViewController (or when AdvancedInfoViewController is dismissed and focus is returned to the ConfigureViewController) in which i can add some logic to clean up MyTextField's firstResponder status?
I've tried viewWillDisappear and viewWillAppear but they are never called on the ConfigureViewController.
I've also tried adding textFieldDidEndEnding to the text field's delegate but, despite it being called, it did not fix the problem.
-(void)textFieldDidEndEditing:(UITextField *)textField
{
[MyTextField resignFirstResponder];
}
You can use [self.view endEditing:YES] to resign all first responders in the case you are presenting myAdvancedInfoViewController.
To return focus to the textField after this event occurs you will need to keep track of which textField was active at the time myAdvancedInfoViewController was presented. When the myAdvancedInfoViewController is dismissed call UITextField's becomeFirstResponder method for the appropriate text field.
I have a UItextField in a UIScrollView. I assigned an inputView (a picker) on my UITextField but it doesn't work. When I click on my textfield, I get the keyboard instead of a picker. When I delete the UIScrollView it works well (I get the picker). Do you have any ideas? Thanks.
Edit (more clear): I have a UItextField in a UIScrollView. I call a method that shows a picker. But the method is never called when my textfield is in a scrollview and I get the keyboard. When I delete the UIScrollView, my method (show picker) is called and I get my picker.
In case you are already using the textfield delegate, try ...
-(BOOL)textFieldShouldBeginEditing:(UITextField *)textField
{
[self openCustomPicker:self]; // Call your IBAction method
return NO; // Hide both keyboard and blinking cursor.
}
to prevent the UITextField from showing the keyboard.
UIPopoverController automatically dismisses when we tap or touch outside the popoverview.
I want to restrict this automatic popover dismissal.
self.myPopovercontroller.passthroughViews=[NSArray arrayWithObject:self.view];
Duplicate of "is there a way NOT to have the popover dismissed when pressing outside it?"
There is a very simple and legit solution. In the view controller that presents your UIPopoverController, conform to the UIPopoverControllerDelegate protocol and implement the following delegate method. I just tested this and it does prevent popover to dismiss.
- (BOOL)popoverControllerShouldDismissPopover:(UIPopoverController *)popoverController
{
return NO;
}
Just make sure that you have set the delegate of your popover controller to the view controller that implements this.
You can dismiss the popover by using [popoverController dismissPopoverAnimated:NO]; method.
Have a read of the UIPopoverController documentation. Specifically...
When displayed, taps outside of the popover window cause the popover
to be dismissed automatically. To allow the user to interact with the
specified views and not dismiss the popover, you can assign one or
more views to the passthroughViews property. Taps inside the popover
window do not automatically cause the popover to be dismissed. Your
view and view controller code must handle actions and events inside
the popover explicitly and call the dismissPopoverAnimated: method as
needed.
Implement popoverControllerShouldDismissPopover: in the delegate, and you can stop it from disappearing unless you want it to.
I was wondering if there was a way to stop an iPad popover from dismissing automatically whenever you touch the screen outside the popover? If not, is there some kind of method similar to "popoverDidDismiss" that I could call to tell when the popover was dismissed?
Yes you can. This is right out of the Apple documentation.
When a popover is dismissed due to user taps outside the popover view, the popover automatically notifies its delegate of the action. If you provide a delegate, you can use this object to prevent the dismissal of the popover or perform additional actions in response to the dismissal. The popoverControllerShouldDismissPopover: delegate method lets you control whether the popover should actually be dismissed. If your delegate does not implement the method, or if your implementation returns YES, the controller dismisses the popover and sends a popoverControllerDidDismissPopover: message to the delegate.
Just return NO to the delegate method popoverControllerShouldDismissPopover:
Here is a link for further reading.
Popover Guide
- (BOOL) popoverControllerShouldDismissPopover:(UIPopoverController *)popoverController
{
return NO;
}
That does it for you and you may assign a specific bar button item or something else in your popover to dismiss the popover.
even u can use
self.modallnpopover = yes;
if you want to dismiss it in a particular view
self.modallnpopover = no;
if you dont want to dismiss it
