Ok so I’ve gone through pretty much all the SO articles on this subject and can’t resolve my particular situation. I have a view controller with 3 text fields and a text area. One of the text fields is for a date. When the user enters this field, I want to hide the keyboard and show the date picker.
The issue I run into with my code so far is that the keyboard shows up when I enter any of the fields, but then does not disappear no matter what I’ve tried.
I could not find any sample app that has this feature and would like some direction on how to resolve this issue.
UPDATE: I fixed the first part of this and now can hide my keyboard when I get to the date field.
This was using the below code:
- (BOOL)textFieldShouldBeginEditing:(UITextField *)textField
{
if ( textField.tag == 1 )
{
[self.view endEditing:TRUE];
[lblDesc2 resignFirstResponder];
[lblTitle resignFirstResponder];
[lblExcerpt resignFirstResponder];
NSLog(@"The method was called for textField ");
[self showDatePicker];
return NO;
}
else
{
return YES;
}
}
Now what I need to do is pull up the date picker and here is my code for that which is not working yet:
- (void) showDatePicker{
CGRect pickerFrame = CGRectMake(0,250,325,0);
datePicker = [[UIDatePicker alloc] initWithFrame:pickerFrame];
[datePicker addTarget:self action:@selector(pickerChanged:) forControlEvents:UIControlEventValueChanged];
[scrollView addSubview:datePicker];
NSDateFormatter *df = [[NSDateFormatter alloc] init];
df.dateStyle = NSDateFormatterMediumStyle;
datePicker.datePickerMode = UIDatePickerModeDate;
[datePicker release];
}
