uipickerview

I have a UIPickerView and The method didSelectRow is not called when tapping on a selected row . I need to handle this case. Any ideas? Nikolay Shubenkov First, conform the class to the UIGestureRecognizerDelegate protocol Then, in the view setup: UITapGestureRecognizer *tapToSelect = [[UITapGestureRecognizer alloc]initWithTarget:self action:@selector(tappedToSelectRow:)]; tapToSelect.delegate = self; [self.pickerView addGestureRecognizer:tapToSelect]; And elsewhere: #pragma mark - Actions - (IBAction)tappedToSelectRow:(UITapGestureRecognizer *)tapRecognizer { if (tapRecognizer.state ==

I'm totally new to swift (and iOS programming at all), but I started messing around with it (it wasn't a good idea when everything is still beta version :D). So I tried to figure it out by myself, but still nothing. Even tried to add subview containing picker without any success. So can any one help me? Well this is my final code which worked for me. It is a mix by a few ideas. The main reasons that I will accept my answer is that my code is in Swift, my code uses UIAlertController, my code is for picker. I want to thank to Jageen - my answer is based on his idea. func showPickerInActionSheet

I have written the following code in the viewDidLoad method: categoryPickerView=[[UIPickerView alloc]init]; categoryPickerView.alpha = 0; [self.view addSubview:categoryPickerView]; categoryPickerView.delegate=self; categoryPickerView.tag=1; and called this method to hide picker view - (IBAction)hidePickerView:(id)sender { [UIView beginAnimations:nil context:nil]; [UIView setAnimationDuration:0.6]; CGAffineTransform transfrom = CGAffineTransformMakeTranslation(0, 200); categoryPickerView.transform = transfrom; categoryPickerView.alpha = categoryPickerView.alpha * (-1) + 1; [UIView

Today on my creative time I did some quite comprehensive research on how to steal touches from a UIScrollView and send them instantly to a specific subview, while maintaining the default behavior for the rest of the scroll view. Consider having a UIPickerView inside of a UITableView. The default behavior is that if you drag your finger over the picker view, the scroll view will scroll and the picker view will remain unchanged. The first thing I tried was to override - (BOOL)touchesShouldCancelInContentView:(UIView *)view and simply not allow the UIScrollView to cancel touches inside the picker

I am adding UIPickerView to UIActionsheet but its working perfectally in ios 7 but not working in ios 8 . Please help me to solve that. Here i attached screenshot for that. Thanks I am using following code for that. UIActionSheet *actionSheet; NSString *pickerType; - (void)createActionSheet { if (actionSheet == nil) { // setup actionsheet to contain the UIPicker actionSheet = [[UIActionSheet alloc] initWithTitle:@"Please select" delegate:self cancelButtonTitle:nil destructiveButtonTitle:nil otherButtonTitles:nil]; actionSheet.backgroundColor = [UIColor clearColor]; UIToolbar *pickerToolbar = [

I'm making a UITextField that has a UIPickerView as inputView . Its all good, except that I can edit by copy, paste, cut and select text, and I don't want it. Only the Picker should modify text field. I've learned that I can disable editing by setting setEnabled or setUserInteractionEnabled to NO . Ok, but the TextField stop responding to touching and the picker don't show up. What can I do to achieve it? Using the textfield delegate, there's a method - (BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string Return NO from this

I'm aware of the pickerView:viewForRow:forComponent:reusingView method, but when using the view it passes in reusingView: how do I change it to use a different text color? If I use view.backgroundColor = [UIColor whiteColor]; none of the views show up anymore. Jon There is a function in the delegate method that is more elegant: Objective-C: - (NSAttributedString *)pickerView:(UIPickerView *)pickerView attributedTitleForRow:(NSInteger)row forComponent:(NSInteger)component { NSString *title = @"sample title"; NSAttributedString *attString = [[NSAttributedString alloc] initWithString:title
