Hide keyboard when selecting another UITextField w/ UIPickerView error - iphone

Question

I'm trying to hide the keyboard when the user selects a UITextField. I currently have three text fields: two UIPickerView (controlled by the same picker) and a textinput field. When I click "return" or on the background, the keyboard disappears via a resignFirstResponder call.
PROBLEM:
When I am currently editing the text input field and then immediately select the UITextField w/ UIPickerView functionality, the keyboard doesn't disappear. I feel like i've tried every solution and am beating by head against a wall...
CODE:
-(void)textFieldDidBeginEditing:(UITextField *)textField{
[pickerView setHidden:YES];
if (fldQuiver.editing == YES) {
[fldTitle resignFirstResponder];
[fldQuiver resignFirstResponder];
[pickerView setHidden:NO];
variabla = 1;
}else if (fldCategory.editing == YES) {
[fldTitle resignFirstResponder];
[fldCategory resignFirstResponder];
[pickerView setHidden:NO];
variabla = 2;
}
NSLog(#"variabla %d",variabla);
[pickerView reloadAllComponents];
}
Any help would be appreciated. Thanks in advance.
EDITED CODE FOR PRINCE:
- (BOOL)textFieldShouldBeginEditing:(UITextField *)textField; // return NO to disallow editing.
{
//set logic for picker view here
if (textField == fldQuiver)
{
variabla = 1;
}
else if (textField == fldCategory) {
variabla = 2;
}
else
{
}
NSLog(#"variabla %d",variabla);
[pickerView reloadAllComponents];
if (textField == fldQuiver)
{
[fldTitle resignFirstResponder];
[pickerView setHidden:NO];
return NO;
}
else if (textField == fldCategory) {
[fldTitle resignFirstResponder];
[pickerView setHidden:NO];
return NO;
}
else
{
[pickerView setHidden:YES];
return YES;
}
}
ALSO: I have "synthesized" and declared #property fldQuiver and fldCategory. I have IBOutlet for fldTitle, fldQuiver, fldCategory.
The pickerView is loaded with an array based on variable.

Answer 1

Use textFieldShouldBeginEditing delegate method for this:
- (BOOL)textFieldShouldBeginEditing:(UITextField *)textField; // return NO to disallow editing.
{
//set logic for picker view here
if (textField == fldQuiver)
{
//picker view hidden or show here
return NO;
}
else if (textField == fldCategory) {
//picker view hidden or show here
return NO;
}
else
{
return YES;
}
}

Answer 2

set delegate for text field
textField.delegate=self;
-(void)textFieldDidBeginEditing:(UITextField *)textField
{
...........
[textField resignFirstResponder]; //it common for all text field,so not use multi resignFirstResponder
............
}
