By default when tapping on a UITextField iOS will display a default keyboard. Is it possible to bypass this? I would like to display modally a custom view controller on tap on the textField and be able to edit the textField through this controller.
Is there a recommended way?
Following wil repalce the keyboard as the input view when the user clicks on the UItextField.
self.TextField.inputView = "your view ";
Ok tried out the exact requirement you asked for:-
- (BOOL)textFieldShouldBeginEditing:(UITextField *)textField
{
[textField resignFirstResponder];
POCModalViewController *objPOCModalViewController = [[POCModalViewController alloc]init];
[self presentViewController:objPOCModalViewController animated:YES completion:nil];
return NO;
}
Where POCModalViewController is the controller you want to present.
I would like to post the solution i have finally implemented, which is the closest to Footyapps27 solution:
I have made the controller that will present the modal controller(which will contain internally multiple custom keyboard views) as the uitextfield delegate for any UITextField objects contained within the view of my controller.
I can now received any notification through the - (BOOL)textFieldShouldBeginEditing:(TWValueInput *)textField method when a textfield start to be edited:
Within that delegate method I have the following code snippet:
- (BOOL)textFieldShouldBeginEditing:(UITextField *)textField {
MyCustomKeyboardVC* vc = [[UIStoryboard storyboardWithName:#"main" bundle:nil] instantiateViewControllerWithIdentifier:#"customKeyboardController"];
vc.delegate = self;
self.modalPresentationStyle = UIModalPresentationCurrentContext;
[self presentViewController:vc animated:NO completion:nil];
return NO;
}
returning NO within that method will prevent the default keyboard from being displayed. There is no need actually to call the resignFirstResponderon the textfield.
I should point out though that the Apple recommended way to display a custom keyboard is to provide a custom view to the textfield inputView property like Divya mentioned. Since i wanted to managed multiple keyboard view entries it was quicker for me to display a custom keyboard controller through the delegate method i mentioned above.

I am writing a Cocoa Mac app in Objective-C and using Storyboard for my UI.
I have a "Confirm" button in my sheetViewController.m which I want to perform some action (save some settings) as well as dismiss the sheetViewController at the same time. They both use the sheetViewController.m as outlets.
Unfortunately, with Storyboard, I can only pick one received action (IBAction) or dismissController.
I want to perform the IBAction FIRST, before dismissing the sheet. How can I accomplish this?
Happy to do this in code as well instead of Storyboard if necessary!
Thanks!
You can use codes to dismiss controller in your IBAction.
I found out how to reference Storyboard ID in code:
On MainViewController:
- (IBAction)didClickButton:(NSButton *)sender {
SheetViewController *sheetViewController = [self.storyboard instantiateControllerWithIdentifier:#"SheetViewController"];
// Must match Storyboard ID
[self presentViewControllerAsSheet:sheetViewController];
}
On SheetViewController:
- (IBAction)didClickButton:(NSButton *)button {
// Do something
[self dismissViewController:self];
}
I have looked around but haven't found a satisfying answer. My problem is that whenever I call popToRootViewControllerAnimated:(BOOL) it is not doing anything. When I NSLog it, it logs (null).
Let me back up a bit here. I have a table view controller that has a list of things, at the navigation bar up top there is an option to add and that takes me to a new view controller with a segue "Present as PopOver" which gets rid of the principal or main navigation bar. So I made one manually and added 2 bar button items "Cancel" and "Add". When "Cancel" is tapped, it should take the user back to the table view controller and discard changes, when "Add" button is tapped, it should also take user back to the previous table view controller with the changes. But it's not doing anything.
Here is my code.
- (IBAction)cancelButton:(UIBarButtonItem *)sender {
UINavigationController * navigationController = self.navigationController;
NSLog(#"%#", navigationController);
NSLog(#"cancel tapped though");
ListingTableViewController *rootController = [[ListingTableViewController alloc] init];
[navigationController popToRootViewControllerAnimated:NO];
[navigationController pushViewController:rootController animated:YES];
}
As far as the segue, this view controller is not connected to anything, or should I connect it? This is a noobish question indeed. Here is my xcode screenshot.
Check this link for the screenshot of the storyboard

You must call
- (IBAction)cancelButton:(UIBarButtonItem *)sender {
NSLog(#"cancel tapped though");
[self dismissViewControllerAnimated:YES completion:nil];
}
instead of popToRootViewControllerAnimated because your VC presented and not pushed!
When presenting a view, you are not pushing it in your navigation controller, but having it presented. To dismiss it, try using [self.presentingViewController dismissViewControllerAnimated:NO completion:nil].
I have a UIVIew which is a subview and it contains several UITextFields. One of these textfields (which is for DATE) should not be editable using the keyboard, instead of this I use a PopOver with a Datepicker inside.
I run a method when the UIControlEventEditingDidBegin is reached. This method calls the resignFirstResponder on the DateTextField.
Everything works fine if the DateTextField is the first field to edit, but when another textField is edited and of course shows the keyboard and then try to edit the DateField, the keyboard doesn't hide and everything goes normal but with the Keyboard doing anything.
I have tried to call the method endEditing:YES before the resignFirstResponder but it doesn't work. I have tried to run the endEditing:YES and resignFirstResponder on the didEndEditing text field method but theres no way to get that keyboard out.
here is my method:
- (void)showDatePopOver:(id)sender{
[self.view endEditing:YES];
UITextField *textField = (UITextField *)sender;
[sender resignFirstResponder]; // hide keyboard
/** POP OVER LINES**/
}
You should use the textFieldShouldBeginEditing: delegate method instead of resigning first responder in didBeginEditing:
This will allow editing on ALL BUT the dateTextField text field:
- (BOOL)textFieldShouldBeginEditing:(UITextField *)textField {
return (![textField isEqual:dateTextField]);
}
You should specify that your view controller is a text view delegate as well like so (in the interface declaration [.h file]):
#interface MyViewController : UIViewController <UITextFieldDelegate>
I'm making an app and i have a view controller with a UISegmentedControl, and a want to switch between a MKMapView and a UITableView.
In the MKMapView i want to display a map with the users current location, and in the TableView i want to list some data. Thats it.
Sounds simple but i'm don't know how to proceed, i tried to make my view controller a tableview controller and then add the MKMapview, also tried to just add both views and a simple view controller. Anyway, there is a right or better way to do that?
Thanks guys!
You can use target-action to have the segmented control hide one view and unhide the other when it's value is changed:
- (void)segmentChanged:(id)sender
{
switch ([sender selectedSegmentIndex]) {
case 0:
{
self.tableView.hidden = NO;
self.mapView.hidden = YES;
break;
}
case 1:
{
self.tableView.hidden = YES;
self.mapView.hidden = NO;
break;
}
default:
break;
}
}
add both as subview
then whenever you want to switch just do
[self.view bringSubviewToFront:YOURVIEW];
The clean way would be to switch the subview, as soon as the button is pressed.
[view1 removeFromSuperView];
[self.view addSubview: view2];
For better performance you could save both views as a member variable, so they don't get instanciated every time.
You could even add a Viewtransition, when doing it in that way. (Eg flipping or fading)
Also in iOS5 you could write your own ViewControllerContainer. But thats way too complicated for that task.
I would use 2 navigationControllers.
Declare your first navigationController as usual, then when user tap the segmentedControl, create your tableController with another navigationController, and display it as modalViewController.
UINavigationController* modalController = [[UINavigationController alloc] initWithRootViewController:tableViewController];
[modalController setToolbarHidden:NO];
[self.navigationController presentModalViewController:modalController animated:YES];
[modalController release];
Then, when user tap the tableViewController's segmented control, just dismiss the viewController.
When an UITextField is firstResponder, I would like to bring to front an UIDatePicker (bottom part of the screen) without the "going down keyboard" (no call to UITextField resignFirstResponder).
The aim is to process like UIKeyboard of UITextField which pop-up on nearly everything when it becomeFirstResponder. modalViewController seems to be fullscreen only.
- showDatePicker:(id)sender {
if([taskName isFirstResponder]) [taskName resignFirstResponder];
[self.view.window addSubview: self.pickerView];
// size up the picker view and compute the start/end frame origin
(...)
[UIView commitAnimations];
}
This example is an animation of keyboard going down, and DatePicker going up, behind and not in front.
Do you know a solution ? A piece of code would be welcome. Thanks in advance.
This is simply done by setting the input view of the text field to the Picker View. Then, on Editing did begin tell the picker view to becomeFirst responder. Like this
textField.inputView = pickerView
then using an IBAction called when the Editing Did Begin
-(IBAction) setPickerViewAsFirstResponder:(id)sender
{
[pickerView becomeFirstResponder];
}
This works perfectly. You'll need to implement code to actually set what the picker view is currently showing to be a string in the text field still.
This definitely can be done... simply implement the method below after setting UIViewController <UITextFieldDelegate> in your .h
Long story short, this overrides the keyboard loading before text editing begins.
- (BOOL)textFieldShouldBeginEditing:(UITextField *)textField {
// Make a new view, or do what you want here
UIDatePicker *pv = [[UIDatePicker alloc] initWithFrame:CGRectMake(0,245,0,0)];
[self.view addSubview:pv];
return NO;
}
