In in my view i have one button when i click on the button i have to set the textfield's inputview property as keyboard how can i do this.please help me.
I'm not exactly sure what you want to do, but probably you want your textField to became active, with a keyboard. That is done with
[textField becameFirstResponder];
and other way around is
[textField resignFirstResponder];

My functionality is to open picker on click of textField. My textfield is inside scrollview is shown in below image.
I want to disable userinteraction of scrollview when picker opens. Following is my code.
- (BOOL)textFieldShouldBeginEditing:(UITextField *)textField
{
[self.picker removeFromSuperview];
[self.toolBar removeFromSuperview];
textField.inputView = self.picker;
textField.inputAccessoryView = self.toolBar;
self.scrollview.userInterationEnabled = NO;
return YES;
}
When I comment the userInteractionEnabled code. Picker is opening perfectly. But when I uncomment code picker is not opened.
Also I gave some delay for this code. so after dalay my picker is hidden again.
The problem here is that userInteractionEnabled is inhereted from the scrollView to the textField. And as it is explained here
A UITextField will also refuse to become first responder if its userInteractionEnabled property is NO as I just discovered. I had to explicitly re-enable user interaction on the text field before it would accept first responder status.
And it can not show the inputView of the textField.
You shou ensure that your textField userInteracationEnables is true or to move the pickerView outside of the textField.inputView.
You can use this cool customizable control for having picker as an inputView on textfield.
Or this one if you want to disable the interaction to background view while picker is open.
There is a requirement of inputAccessoryView is for the chat application.
When I add inputAccessoryView to UITextField on tap event of UIButton. That view is set as inputAccessoryView completely but text field is not becoming first responder.
(Note: Super view of textfield is viewText.)
- (IBAction)btnOpenTextField:(id)sender
{
UIView *accessoryView=[[UIView alloc]init];
accessoryView.frame=CGRectMake(0,0, _viewText.frame.size.width, _viewText.frame.size.height);
[accessoryView addSubview:_viewText];
_txtMessage.inputAccessoryView = accessoryView;
[_txtMessage becomeFirstResponder];
}
Thanks in Advance.
You can call [_textMessage reloadInputViews], replacing [_text becomeFirstResponder].
What you want to achieve is quite not possible, this will cause recursion, alternatively what you can do is put a textfield on bottom of the screen and when the textfield is selected you can animate it up with the flow of the keyboard. i think this is an appropriate solution if i got your question correctly.
When a UITextField is selected and has a keyboard shown, if I tap other parts of the view the keyboard disappears.
If I tap another UITextField, the keyboard stays up, the first textfield is deselected, and nothing happens. Then I need to tap on the other UITextFIeld again for selection to happen and a keyboard to appear.
Is there a way to make a second UITextField immediately accessible when a first UITextField is selected?
If you reload the tableview in textFieldDidEndEditing, you'll break selection in this way. Don't do that.
try it, press another view should call below fn.
-(void)disappearKey{
[self.view endEditing:YES];
}
after keyboard disappear, Tap any textfield, will appear keyboard.
First of all I think its a bug that the keyboard is not dismissed and opened again when tapping on another UITextField or UITextView. It should be reported and Apple should fix it.
Using the textfield delegate methods and registering for keyboard notification it should be possible to manually keep track if the user tapped on another textfield and the keyboard did not close and reopen. At the very least you should be able to detect when this is happening and close the keyboard manually by [textField resignFirstResponder];
The keyboard notification are as follows:
UIKeyboardWillShowNotification
UIKeyboardDidShowNotification
UIKeyboardWillHideNotification
UIKeyboardDidHideNotification
I'm''pretty sure you know the UITextfield and textview delegate methods
– textFieldShouldBeginEditing:
– textFieldDidBeginEditing:
– textFieldShouldEndEditing:
– textFieldDidEndEditing:
I am not in an active project at the moment so I'm not sure if I just ignored the problem but I can't recall this happening to me.
you can use BSKeyboardControls. just see the demo and decide to
use or not.
or you can do you have to set tag in sequence to the each textfield
in uiview. then use the below code.
-(BOOL)textFieldShouldReturn:(UITextField*)textField
{
NSInteger nextTag = textField.tag + 1;
UIResponder* nextResponder = [textField.superview viewWithTag:nextTag];
if (nextResponder) {
[nextResponder becomeFirstResponder];
} else {
[textField resignFirstResponder];
}
return NO;
}
I have an UITextview, when user taps on UITextview i need to hide the default keyboard. For that i have done,
[myTextView setEditable: NO];
So the keyboard is not shown, here i have created an Custom View with UIButton, i need to show this UIView when the user taps on UITextView, for that i have done,
textViewDidBeginEditing{
//Here i have added UIView as subview
}
But this method is not working because of,
[myTextView setEditable: NO];
and i need to close the UIView when user clicks the close button inside the UIView
You should be using resignFirstResponder instead of setting the UITextView to not editable. This will hide the system keyboard.
[myTextView resignFirstResponder];
If you want to use a different view for the keyboard then the system provided one then set inputView on the UITextView to the custom view you want to be used in place of the system keyboard.
myTextView.inputView = myCustomView;
Perhaps using textFieldShouldBeginEditing instead of setEditable: NO works?
- (BOOL)textFieldShouldBeginEditing:(UITextField *)textField
{
//Here i have added UIView as subview
return NO;
}
How can I bring up the iphone keyboard by clicking a button - I haven't created any text fields. My intention is to have labels that hold a single character.
Other people have asked this and it has been answered but it was from years ago and I didn't understand what people meant in there responses.
Thank you for any help in advance.
Only way you could do this is via hidden UITextField, and set that textField to becomeFirstResponder
you could hide the text field in your code liket his textfield.hidden=YES;
or you could hide the textfield from nib file also by going into the attribute inspector and tick the Hidden property
You could have a look at this UIKeyInput- Displaying keyboard in iPhone without UITextField or UITextView, I have not tried myself this
Attach the button to a touchUpInside event and call becomeFirstResponder on the textView or textfield:
Here is an example (to bring it up when a text view is clicked):
-(IBAction)buttonClicked:(id)sender{
[textView becomeFirstResponder];
}
-(void)ButtonClicked
{
[textFld becomeFirstResponder];
[textView becomeFirstResponder];
}
use this method
You can add a hidden UITextFeild as tempTF and when the button clicked. call becomeFirstResponder of this textFeild:
[self.tempTF becomeFirstResponder];
To Hide textField:
UITextField *tempTF = [[UITextField alloc] init];
tempTF.hidden = YES
or mark Hidden ir your Interface Builder
