startDateSelected =NO;
endDateSelected = YES;
// [self.view endEditing:YES];
// [referenceNmbrTxtFld resignFirstResponder];
// [endDateTxtFld becomeFirstResponder];
// textField.inputView=datePicker;
// [[UIApplication sharedApplication] sendAction:#selector(resignFirstResponder) to:nil from:nil forEvent:nil];
// [APP_DELEGATE.window resignFirstResponder];
[[[UIApplication sharedApplication] keyWindow] endEditing:YES];
[UIView animateWithDuration:0.5 animations:^
{
// [endDateTxtFld resignFirstResponder];
_bottomGap4DatePicker.constant=0;
datePicker.backgroundColor=[UIColor whiteColor];
//[_subVw4DtPkr becomeFirstResponder];
}];
[self.navigationController.view endEditing:YES];
}
else
{
[textField becomeFirstResponder];
_bottomGap4DatePicker.constant=[UIScreen mainScreen].bounds.size.height +_subVw4DtPkr.frame.size.height;
_popUpVwConstraint.constant=-30;
}
}

Answer 1

Hide keyboard Anywhere in IOS :
- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
for (UIView * txt in self.view.subviews){
if ([txt isKindOfClass:[UITextField class]] && [txt isFirstResponder]) {
[txt resignFirstResponder];
}
}
}
OR
- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
[self.view endEditing:YES];
}

Answer 2

I tried all the solution, like adding
UITextFieldDelegate
tf_edit.returnKeyType = UIReturnKeyDone
- (BOOL)disablesAutomaticKeyboardDismissal
{
return NO;
}
Nothing helped.
textFieldShouldReturn was being called. but keyboard was not appearing. I read that it is going to some other textfield when I am clicking DONE button. But there was no other textfield. So instead of applying resignFirstResponder to my textfield name, I applied to the textfield which is a parameter of textFieldShouldReturn function and it worked. I am not sure if it is correct way. It worked for me.
-(BOOL)textFieldShouldReturn:(UITextField *)textField
{
//[tf_edit resignFirstResponder];
[textField resignFirstResponder];
return YES;
}

(BOOL)textFieldShouldBeginEditing:(UITextField *)textField { {
NSLog(#"textFieldDidBeginEditing===%#" , textField.text);
CGAffineTransform translation = CGAffineTransformIdentity;
if (textField==vacDate || textField==vacTime) {
[self.view endEditing:YES];
[UIView beginAnimations:nil context:nil];
self.view.transform = translation;
[UIView commitAnimations];
myDatePicker.hidden = NO;
return NO;
}
else
{
if (textField==vacType) {
translation = CGAffineTransformMakeTranslation(0, -60);
}
[UIView beginAnimations:nil context:nil];
self.view.transform = translation;
[UIView commitAnimations];
myDatePicker.hidden = YES;
return YES;
}
}
