I have designed a keyboard on my app Now I have the query is that whenever somebody tap on the textfield the keyboard on the device appear which i don't want
is there any way to disable the keyboard so that the user can see the keyboard designed on this app.
In your ViewController add the delegate of the UITextField :
#interface ViewController : UIViewController <UITextFieldDelegate>
While Creating the UITextField or in ViewDidLoad:
self.myTextField.delegate = self;
In your implementation file:
#pragma mark - UITextFieldDelegate
-(void)textFieldDidBeginEditing:(UITextField *)textField
{
[textField resignFirstResponder];
}
- (BOOL)textFieldShouldBeginEditing:(UITextField *)textField
{
return NO;
}
Note that you can set the return of textFieldShouldBeginEditing to NO or YES according to your needs, in your case you may return YES , but provide the logic of displaying your custom keyboard
-(BOOL)textFieldShouldBeginEditing:(UITextField *)textField
{
return NO;
}
And Needs to add delegate <UITextFieldDelegate>
In this method you also can write code to show your custom keyboard.
lol
Set the inputView to a zero sized view:
textField.inputView = [[UIView alloc] initWithFrame:CGRectZero];
You can use following approach to restrict keyboard display when user tap on it :
Method : 1
-(BOOL)textFieldShouldBeginEditing:(UITextField *)textField
{
return NO;
}
This method hide the Keyboard and dont show the cursor.
Method : 2
UIView* HideView = [[[UIView alloc] initWithFrame:CGRectMake(0, 0, 1, 1)] autorelease];
textField.inputView = HideView;
This method hide the Keyboard, but Cursor is appear.
You can disable user interaction.
textField.userInteractionEnabled = NO;

How can I disable the keyboard when I touch-up inside a UITextField?
What I want to do is show a custom digital keyboard instead of the default one.
If I understand correctly that you are looking to create a custom keyboard in the app, I don't think we need to disable the default keyboard when we touch-up inside a UITextField.
We just need to create a custom view and assign it to the inputView property of the UITextField to replace the default keyboard.
For example, something like this:
yourTextField.inputView = yourCustomKeyboardView
See more here.
Note: For Objective-C (Xcode)
In your viewDidLoad: set delegate for textfields which you want to disable.
self.textfield.delegate = self;
and insert this delegate function:
- (BOOL)textFieldShouldBeginEditing:(UITextField *)textField {
if (textField == yourTextfiledOutletInstance) {
[self showCustomkeyboard];
return NO;
}
return YES;
}
//Show custom keyboard
-(void)showCustomkeyboard{
// Handle your operation here to show custom keyboard
}
set the UITextField delegate in the ViewController class, and then add this method in the class
- (BOOL)textFieldShouldReturn:(UITextField *)textField {
[textField resignFirstResponder];
return NO;
}
Use resignFirstResponder to dismiss your keyboard.
- (BOOL)textFieldShouldReturn:(UITextField *)textField {
[textField resignFirstResponder];
return NO;
}
set inputView on the UITextView to the custom view you want to be used in place of the system keyboard.
myTextView.inputView = myCustomView;
I am devolepeing an app where i am entering data to a textfield from custom view(not input view).Problem is that i don't want the system keypad to popup when i touch the textfield.I have gone through Apple text programming document but was not able to find the solution.How to achieve this.
You can also use gestures,
- (void)viewDidLoad {
[super viewDidLoad];
UITapGestureRecognizer *gestureRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:#selector(hideKeyboard)];
gestureRecognizer.cancelsTouchesInView = NO;
[self.view addGestureRecognizer:gestureRecognizer];
}
- (void)hideKeyboard {
[self.view endEditing:YES];
}
try this code may help you
-(BOOL)textFieldShouldBeginEditing:(UITextField *)textField{
if (textField==/**urs testField on which you want to remove keyboard on click*/ ) {
[textField resignFirstResponder];
//*its depend your requirement
[here you can call yours custom view];
}
return YES;
}
adjust as per req..
Set the userInteractionEnabled property:
//UITextField *text;
text.userInteractionEnabled = NO;
Not sure, what exactly you are expecting. I hope that you need to handle the UITextField delegates but without UIKeyboard : If so, then implement delegate of
-(void)textFieldDidBeginEditing:(UITextField *)sender{
// resign the textfield and do your stuff with the data
}
Assign a IBOutlet property to that particular UITextField
and then in viewDidLoad add the following code [self.YourUITextField setUserInteractionEnabled:NO];
Disable the editing for the particular field
-(BOOL)textFieldShouldBeginEditing:(UITextField *)textField{
if ([textField isEqual:myTextField]) {
return NO;
}
return YES;
}
-(BOOL)textFieldShouldBeginEditing:(UITextField *)textField
{
[self.view endEditing:YES]; // this statement will hide keyboard. Useful when we use many textfields based on tag value.
return YES;
}
I'd like to dismiss the keyboard with a text field using
- (BOOL)textFieldShouldReturn:(UITextField *)textField {, but I need to do the same with a text view, so I'll use - (BOOL)textViewShouldReturn:(UITextView *)textView {. Is it possible to put them togheter in the same AppDelegate?
Thank you.
Yes, you can have two delegates
#interface ViewController : UIViewController<UITextFieldDelegate,UITextViewDelegate>
Unfortunately
The protocol UITextViewDelegate does not have, something like this.
- (BOOL)textViewShouldReturn:(UITextView *)textView {
UITextViewDelegate Protocol,
EDIT 1 :
Button press event to hide the keyboard.
-(IBAction) yourButtonPressed:(id)sender;{
for(UIView *v in self.view.subviews){
if([v isKindOfClass:[UITextField class]] || [v isKindOfClass:[UITextView class]]){
if([v isFirstResponder]){
[v resignFirstResponder];
break;
}
}
}
}
I don't fully understand your question...
Basically you will do the following:
implement the UITextFieldDelegate and UITextViewDelegate in your
viewController
implement the methods of that delegates, you need/want
resignFirstResponder / endEditing of the textField / textView, where
ever you want
Just subscribe to the delegates from your viewController and make sure to set the delegate on those objects to your viewController.
.h
#interface YourViewController : UIViewController <UITextFieldDelegate, UITextViewDelegate>
.m
someTextField.delegate = self;
someTextView.delegate = self;
From the sound of it you just need to tie into the actions of the textField and textView. Create an IBAction and tie it to what you'd like. Then you can resignFirstResponder from that IBAction.
Use this action for both your textField and textView
- (IBAction)lowerTheText:(id)sender
{
[sender resignFirstResponder];
}
Yes, with a UITextView it's tricky. As I say in my book...
http://www.apeth.com/iOSBook/ch23.html#_uitextview
...on the iPad, the problem of dismissing the keyboard doesn't arise because the user can dismiss it with the button in the lower right corner of the keyboard. So this leaves only the iPhone. You will typically have an interface such that there is a Done button or similar. Look at how the Notes app solves this, for example.
The process itself is just the same: call endEditing: on the superview and whoever is first responder will cease being first responder and the keyboard will retire.
Yes, you can use textfield delegate and textview delegate in the same application.
TextField:
#interface ViewController : UIViewController<UITextFieldDelegate,UITextViewDelegate>
// This allocates the textfield and sets its frame (or) you can use interfaceBuild
UITextField *textField = [[UITextField alloc] initWithFrame:
CGRectMake(20, 50, 280, 30)];
textField.delegate=self;
// This method enables or disables the processing of return key
-(BOOL) textFieldShouldReturn:(UITextField *)textField{
[textField resignFirstResponder]; // this is event for hide keyboard.
return YES;
}
TextView:
// init
UITextView *textView = [[UITextView alloc] initWithFrame:
CGRectMake(20, 50, 280, 30)];
- (void)textViewDidChangeSelection:(UITextView *)textView
{
[textField resignFirstResponder]; // this is event for hide keyboard.
}
In iPhone, I have a view which has a UITextField. When I tap on the clear button of UITextField's the keyboard dismissed instead of clearing the text in the UITextField. On an iPad it is working correctly. What can I do to fix this?
Just clear the field, resignFirstResponder (if you want to hide keyboard) and return NO/false
Note: set Attributes inspector property of UITextField
Clear Button -> Appears while editing
so it will display the clear button while editing in the text field.
// Objective-C
-(BOOL)textFieldShouldClear:(UITextField *)textField
{
textField.text = #"";
[textField resignFirstResponder];
return NO;
}
// Swift
func textFieldShouldClear(textField: UITextField) -> Bool {
textField.text = ""
textField.resignFirstResponder()
return false
}
Try this code after you attach delegate of uitextifield
-(BOOL)textFieldShouldClear:(UITextField *)textField
{
return true;
}
First, check all the code blocks that related to your UITextField (especially the code yourTextField.hidden = YES;)
Put break points and analyze every UITextField delegates that you implemented.
(textFieldDidEndEditing,textFieldShouldEndEditing,textFieldShouldReturn.etc.)
OR
Implement the textFieldShouldClear delegate and write the code here to visible and clear your UITextField
To do this, you have to set the clearButtonMode as below,
yourTextField.clearButtonMode = UITextFieldViewModeWhileEditing;
yourTextField.delegate = self;
//For active keyboard again
[yourTextField becomeFirstResponder];
Then implement the textFieldShouldClear delegate
YourClass.h
#interface className : UIViewController <UITextFieldDelegate>
YourClass.m
-(BOOL)textFieldShouldClear:(UITextField *)textField {
yourTextField.hidden = NO;
yourTextField.text = #"";
return YES;
}
Just make sure U've given these two
editingTextField.delegate = self;
editingTextField.clearButtonMode = UITextFieldViewModeWhileEditing;
TextFieldShouldClear is needed only if you need to do some customizations :-)
Are you doing some thing in this method?
Maybe you are are calling resignFirstResponder in this delegate method, thats why the keyboard is getting dismissed.
Please go through the delegate methods, and check what u r doing exactly.
This issue happened also if you have
yourTextField.clearButtonMode = UITextFieldViewModeNever;
Check this line and delete it or change view mode..
In my app I have a view that is a form that has quite a few inputs.
When the UITextField calls textFieldDidBeginEditing, it checks the tag and will bring up a UIPopoverController or the keyboard depending on the what the input is meant to be.
If the keyboard is up, I need it disappear when the user presses a textfield that brings up the popover. However I cannot make it disappear, I have tried every way to get rid of the keyboard but it just stays there. I have tried:
calling resignFirstResponder in textFieldDidEndEditing
calling [self.view endEditing:YES] in textFieldDidEndEditing
calling resignFirstResponder AND [self.view endEditing:YES] in textFieldDidBeginEditing checking for the previous tag is equal to a keyboard input text field.
Any ideas would be great.
I have ripped it out and and put it in a example project if anyone wants to see the exact behaviour.
http://dl.dropbox.com/u/61692457/KB_Test.zip
Declare a Global UITextField in .h file
UITextField *txtfld;
Replace Your method textFieldDidBeginEditing with textFieldShouldBeginEditing and now write this code
- (BOOL)textFieldShouldBeginEditing:(UITextField *)textField
{
if (textField.tag == 1 || textField.tag==3)
{
if(numPickerPopover == nil)
{
numPicker = [[[NumPicker alloc] initWithStyle:UITableViewStylePlain] autorelease];
numPicker.delegate = self;
numPickerPopover = [[UIPopoverController alloc] initWithContentViewController:numPicker];
[numPickerPopover setPopoverContentSize:CGSizeMake(60.0, 260.0f)];
}
[numPickerPopover presentPopoverFromRect:textField.frame inView:self.view permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
[txtfld resignFirstResponder];
return NO;
}
if (textField.tag == 2)
{
txtfld = textField;
return YES;
}
return YES;
}
To dismiss the keyboard when the user touches the textField that brought it up, add this method:
- (IBAction)dismissKeyboard:(id)sender {
[textField resignFirstResponder];
}
In Interface Builder, connect this method to the textField event you want, like touch up inside (or whatever is more appropriate).
