Keyboard response Slow in ios

Question

I am creating dynamic screen and creating text field dynamically When I touch the text field and start writing then my keyboard response is slow and take almost 3-4 seconds to when a character is displayed on the screen. How can i fix this problem? Thanks in advance.

    - (BOOL) textFieldShouldBeginEditing:(UITextField *)textField
{
    NSInteger componentType;
    BOOL isEditable = YES;


    for (int i = 0; i < self.screenComponentData.count; i++)
    {
        if ([self.keyboardType[i] intValue] == NUMERIC)
        {
            [textField setKeyboardType:UIKeyboardTypeNumberPad];

        }
        else if([self.keyboardType[i] intValue] == ALPHA)
        {
            [textField setKeyboardType:UIKeyboardTypeAlphabet];

        }
        else if([self.keyboardType[i] intValue] == ALPHANUMERIC)
        {
            [textField setKeyboardType:UIKeyboardTypeDefault];
        }

        NSString *str = [self.entityMap objectAtIndex:i];
//        str = [str substringFromIndex:2];
        if (textField.tag == [str intValue])
        {
          componentType = [self.screenComponentData[i][3] intValue];
            if ([self.screenComponentData[i][7] characterAtIndex:27]  == NON_EDITABLE)
            {
                isEditable = NO;
            }
            break;
        }
    }

    if (componentType == DATE_PICKER || componentType == TIME_PICKER || componentType == VALUE_PICKER)
    {
        [self textFieldTouched:textField];
        return NO;
    }
    else if(isEditable == NO)
    {
        //Dont show picker  & dont allow user to edit too.SHOW DEFAULT TEXT
        return NO;
    }
    else
    {
        return YES;
