Question

New to objective c and this maybe a simple error. I am trying to dismiss all 3 UITextField keyboard which i have for UIPickerView. Whereby the keyboard won’t appear only the picker view would be shown. I did some research but can’t figure it out. Here is the code for the .m file and it won’t work.

-(void)textFieldDidBeginEditing:(UITextField*)textField;
{
    [textField resignFirstResponder];
    modeArray = [[NSMutableArray alloc] init];
    if(textField.tag==1){
        [modeArray addObject:@" bus "];
        [modeArray addObject:@" bus/mrt "];
        tbMode.inputView = pickerView;
        pickerView.hidden = NO;
    }
    else{
        if(textField.tag==2){
            [modeArray addObject:@" 300 "];
            [modeArray addObject:@" 400 "]; 
            [modeArray addObject:@" 500 "];
            tbWalkDist.inputView = pickerView;
            pickerView.hidden = NO;
        }
        else{
            if(textField.tag==3){
                [modeArray addObject:@" cheapest "];
                [modeArray addObject:@" fastest "];
                tbRouteOpt.inputView = pickerView;
                pickerView.hidden = NO;
            }
            else{
                pickerView.hidden=YES;
            }
        }
    }
}

how should i dismiss the keyboard only showing the picker view? Using this line [textField resignFirstResponder]; can i use to dimiss the keyboard?

Answer 1

You need to delegate all your text fields to the viewController and then use the method;

-(BOOL)textFieldShouldReturn:(UITextField *)textField // called from textfield (keyboard) 
{
//... place your [textField resignFirstResponder]; logic here
}

Make sure you add the text view delegate protocol to your viewcontroller .h file

@interface ViewController : UIViewController <UITextViewDelegate>
