ToolBar at the top of UIPIckerView in xcode?

Question

I need to add a toolbar with done button on the top of UIPickerView. I don\'t want to use actionSheet because I want the rest of the v

Answer 1

in viewDidLoad just add this code and when textFieldBegin just change frame like bellow...

First Create global UIView For back View of Date Picker in .h file like bellow..

UIView *viewPicker;
UIPickerView * pickerView;

and then use it like bellow..

- (BOOL)textFieldShouldBeginEditing:(UITextField *)textField {
    [UIView beginAnimations:nil context:NULL];
    [UIView setAnimationDuration:0.3];
    viewPicker.frame = CGRectMake(0, 112, 320, viewPicker.frame.size.height);  
    [UIView commitAnimations];
    return YES;
}

add this bellow code...

    viewPicker = [[UIView alloc]initWithFrame:CGRectMake(0, 480, 320, 258)];
    UIToolbar* toolbar = [[UIToolbar alloc] init];
    toolbar.frame=CGRectMake(0,0,320,44);
    toolbar.barStyle = UIBarStyleBlackTranslucent;
    UIBarButtonItem *flexibleSpaceLeft = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil];


    UIBarButtonItem* doneButton = [[UIBarButtonItem alloc] initWithTitle:@"Done"
                                                                   style:UIBarButtonItemStyleDone target:self
                                                                  action:@selector(doneClicked:)];


    [toolbar setItems:[NSArray arrayWithObjects:flexibleSpaceLeft, doneButton, nil]];
    pickerView = [[UIPickerView alloc]init] ;
    pickerView.frame=CGRectMake(0, 44, 320,216);
    pickerView.delegate = self;
    pickerView.showsSelectionIndicator = YES;

    [viewPicker addSubview:pickerView];
    [viewPicker addSubview:toolbar];
    [self.view addSubview:viewPicker];

and in Done button clicked just set again frame like this..

-(IBAction)doneClicked:(id)sender
{
    [UIView beginAnimations:nil context:NULL];
    [UIView setAnimationDuration:0.3];
    viewPicker.frame = CGRectMake(0, 370, 320, 258);
    [UIView commitAnimations];
}

i hope this help you...
