In my application , I want to show one popover view, whenever I am clicking in textfield.
Which text field delegate method should I call?
you have to write your functionality in
-(void)textFieldDidBeginEditing:(UITextField *)textField{
// became first responder
}
Use on the UITextFieldDelegate protocol......
- (BOOL)textFieldShouldBeginEditing:(UITextField *)textField {
NSLog(#"Editing Should Editing"); // SAVE PROCEDURE
}

in my uitableview in each cell I'm having uitextfield when user edits the textfield and after pressing any other button on the screen the Keyboard is not resigning. I did the following in textfield delegates
- (void)textFieldDidBeginEditing:(UITextField *)textField
{
textfieldInCell = textField;
}
-(BOOL)textFieldShouldReturn:(UITextField *)textField
{
[textField resignFirstResponder];
textfieldInCell=nil;// this is the ivar i am using for each textfield in cell.
return YES;
}
-(void)textFieldDidEndEditing:(UITextField *)textField
{
textfieldInCell=textField;
// do the process...
textfieldInCell=nil
}
I am also calling the shouldReturn delegate function once the user tapping on any other button but the keyboard is not resigning. Where am I going wrong?
Confirm that you bind the delegate of each textfield that you create with the view controller and add one line of code in textfield did end editing :-
-(void)textFieldDidEndEditing:(UITextField *)textField
{
// add the following line
[textField resignFirstResponder];
textfieldInCell=textField;
// do the process...
textfieldInCell=nil
}
have you bind delegate of textfield with your controller? or did you check textFieldShouldReturn calling or not?
i think, binding is missing wit view controller in your case.
thanks
add a line in your tableview where you are adding textfield.
<YOUR_TEXTFIELD>.delegate = YES;
Enjoy Programming
first check that you give the delegate or not and give the delegate to UITextField after that when you call the method of button at that time resign this textfield like bellow...
-(IBAction)yourButton_Clicked(id)sender{
[yourTextField resignFirstResponder];
////your code write here
}
you must try to assign tag value to textfield then in should return method you used that tag to hide the keyboard like this (if you assign the tag -1 then)
-(void)textFieldDidEndEditing:(UITextField *)textField{
if(textField.tag==-1){
[textField resignFirstResponder];
}
}
I've got a UIViewController with an additional small UIView I created on top of it (subview). When I click a button this view hovers to the center of the screen. The issue is the i've got a UITextField in the additional UIView and i cannot seem to get the return key to work.
Although I set my IBAction to the event "Editing did end" of the text field, when i click the return key, the IBAction doesn't run.
What am I doing wrong?
you just set Your Delegate for example :- yourtextfile.delegate=self; and also dont forget to add delegate method in to .h file
#interface contacts_detailView : UIViewController<UITextFieldDelegate>
and then you delegate textFieldDidEndEditing
- (void)textFieldDidEndEditing:(UITextField *)textField
{
//your new view apear code here
[textField resignFirstResponder];
}
make sure UITextFieldDelegate at interface
Clicking on "Return" doesn't trigger an "Editing did end" event. Only when you'll call resignFirstResponder on the UITextField will you see the event triggered.
What you should do is set your UIViewController as the delegate of the UITextField and implement the method
- (BOOL)textFieldShouldReturn:(UITextField *)textField
{
[textField resignFirstResponder];
return YES;
}
First of all, delegate the TextField to the file's owner like this:
yourtextField.delegate = self in your viewDidLoad.
And then add this to the view controller
- (BOOL)textFieldShouldReturn:(UITextField *)textField
{
[textField resignFirstResponder];
return YES;
}
It should work.
There is no need to write more code for key board return. Please write this in your .m file , it will work for any number of text field , no need to write again again for different textfield.
use <UItextfieldDelegate> in your .h file. Then make wiring with fileowner in nib file.
- (BOOL)textFieldShouldReturn:(UITextField *)textField
{
[self.view endEditing:YES];
return YES;
}
I'm working on an app that has a signup feature. The signup process is broken up into 3 different views, each of which has 2 UITextField to take user input. I have also implemented the UITextFieldDelegate methods;
- (void)textFieldDidBeginEditing:(UITextField *)textField;
- (BOOL)textFieldShouldEndEditing:(UITextField *)textField;
- (void)textFieldDidEndEditing:(UITextField *)textField;
and
- (BOOL)textFieldShouldReturn:(UITextField *)textField;
Depending on which UITextField is in focus will determine what method is called when the user taps the return key on the keyboard. I would like to just call my resignFirstResponder method for the first 4 UITextFields but on the last textField I would like to call my join method when return is pressed.
So my question is; How can I determine which UITextField just called the textFieldShouldReturn: method?
As always, thanks in advance!
- (BOOL)textFieldShouldReturn:(UITextField *)textField {
if (textField == theLastTextField) {
//joinmethod
} else {
[textField resignFirstResponder];
}
}
We want the keyboard to be dismissed each time the user moves to a new field. What event would be appropriate to place a resignFirstResponder call?
Thanks.
Your most likely looking for the textFieldShouldReturn delegate
- (BOOL)textFieldShouldReturn:(UITextField *)textField;
Use the appropriate UITextFieldDelegate method:
- (BOOL)textFieldShouldReturn:(UITextField *)textField
{
[textField resignFirstResponder]
return YES;
}
How to Hide Keyboard by pressing Returnkey
There is a couple of things you need to remember. The number #1 part developers forget to set is the delegate of the textField.
If you are using the Interface Builder, you must remember that you need to set the delegate of the textField to the file Owner.
alt text http://www.thoughtblog.com/imgs/delegate.png
If you are not using Interface Builder then make sure you set the delegate of the textfield to self. I also include the returnType. For Example if the textField was called gameField:
gameField.delegate = self;
gameField.returnType = UIReturnKeyDone;
You must also implement the UITextFieldDelegate for your ViewController.
#interface YourViewController : UIViewController <UITextFieldDelegate>
Finally you need to use the textFieldShouldReturn method and call [textField resignFirstResponder]
-(BOOL) textFieldShouldReturn:(UITextField*) textField {
[textField resignFirstResponder];
return YES;
}
All your textFields will use this same method so you only need to have this setup once. As long as the delegate is set for the textField, the UITextFieldDelegate is implemented for the interface, you add the textFieldShouldReturn method and call the
resignFirstResponder your set.
The keyboard only shows up when something editable (usually a UITextField) has become the first responder. Therefore, to make the keyboard go away, you have to make the textField not be the firstResponder anymore. Fortunately, it's one line of code:
[myTextField resignFirstResponder];
You really need to include more information with your question, but I think this might be what you are looking for:
First, make your view controller implement the UITextFieldDelegate:
#interface MainViewController : UIViewController <UITextFieldDelegate> {
Then add this method to the controller:
- (BOOL)textFieldShouldReturn:(UITextField *)textField {
[textField resignFirstResponder];
return YES;
}
Read the UITextFieldDelegate documentation to see what else you can do.
Use these two methods:
- (BOOL)textFieldShouldBeginEditing:(UITextField *)textField {
activeTextField = textField;
return YES;
}
- (BOOL)textFieldShouldReturn:(UITextField *)textField {
activeTextField = nil;
[txtPassword resignFirstResponder];
[txtUserName resignFirstResponder];
return YES;
}
Please make sure you have given delegates to each textfields. For that you should go to the view. Right click . set the delegate to view.
