Question

This question already has an answer here:
Issue related to textfield and datepicker
(1 answer)
Closed 6 years ago.
I have two textFields. On click, the first one is showing a qwerty keyboard and the second one is showing picker.
My issue is when I'm clicking on my first textField, the keyboard is showing properly. Now, After I type anything, I directly want to click on the second textField which is the showing picker and the keyboard should disappear, but the keyboard is still there.
I want to hide the keyboard as soon as I click on the second textField.

Answer 1

There are two ways to achieve this -
First: Use the UITextFieldDelegate.
For that-
List the UITextFieldDelegate in your view Controller's protocol list like,
#interface ViewController : UIViewController <UITextFieldDelegate>
Then make your ViewController conform to the Textfield's delegate to implement the methods like textFieldDidBeginEditing, and textFieldDidEndEditing:
So, go to the viewDidLoad method and conform to the UITextField's protocol like-
- (void)viewDidLoad
{
[super viewDidLoad];
self.firstTextField.delegate = self; //assuming your first textfield's
//name is firstTextField
//Also give your first textfield a tag to identify later
self.firstTextField.tag = 1;
}
Now, you are set to implement the delegate methods. But, to achieve your target first, you need to take a UITextField instance to know when you are typing in the firstTextField. So, declare a property of UITextField type. Do that in the interface file like-
#property(nonatomic, strong) UITextField *currentTextField;
Now in the textFieldDidBeginEditing delegate method, assign the firstTextField instance to the currentTextField when you start typing in it like-
- (void)textFieldDidBeginEditing:(UITextField *)textField{
if(textField.tag == 1){
self.currentTextField = textField;
}
}
After that in the textFieldDidEndEditing method, check if it is the current textfield from which you are coming out and dismiss the keyboard like-
-(void)textFieldDidEndEditing:(UITextField *)textField{
if(textField.tag == 1){
[self.currentTextField resignFirstResponder];
}
return YES;
}
Second: You can use UIResponder. As ViewControllers inherit from UIResponder, you just override the method- touchesBegan:withEvent method, something like-
-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event{
[self.view endEditing:YES];// this will do the trick
}
In this case, when you click out side the textField, the keyboard should automatically disappear.

Answer 2

use UITextFieldDelegate set delegate to self in ViewDidLoad and then put this code
func textFieldDidEndEditing(textField: UITextField)
{
yourtextfieldname.resignFirstResponder()
return true
}

Answer 3

Step 1 :- Code for ViewController.h :-
//add UITextFieldDelegate just after UIViewController
#interface ViewController : UIViewController<UITextFieldDelegate>
Step 2 :- Code For ViewController.m :-
//inside viewdidLoad write following code, where txtInput is outlet for input text field
_txtInput.delegate = self;
// Last Thing write following code just above #end
-(BOOL)textFieldShouldReturn:(UITextField *)textField
{
[textField resignFirstResponder];
return YES;
}
//that's it use this very simple way
