I have a picker view in a view controller page,say view controller1.Now I have a requirement of accessing the selected string value from that picker view in another view controller say view controller 2. This is because,I have a table view which displays the saved data corresponding to 4 groups i.e. my application is reminder application which user saves the reminder,that is visible in view reminder page.The reminders are saved by the user in respective groups,say friends,family,office etc... So I have earlier retrieved in a bad programming context,i.e. I took 4 view controllers for displaying

I am trying to create a form in which each text field has a UIPickerView which the user can use to select the option needed. I need a to use a different array of information for each text field but I can't seem to get it to work and I have been stuck on it for quite a while now. I have had a method which was possibly working but I couldn't then retrieve the data from the text field for Firebase due to each field having the same name. Here is my code so far, this is the latest method that I have tried that doesn't work: import UIKit import Firebase import FirebaseDatabase class

I'd like to get the row value in real-time as the iPhone user spins a wheel in a UIPickerView (not just when the wheel settles onto a particular row). I looked into subclassing UIPickerView then overriding the mouseDown method, but I couldn't get this to work. Any suggestions would be very much appreciated. Perhaps try implementing the delegate method: - (UIView *)pickerView:(UIPickerView *)pickerView viewForRow:(NSInteger)row forComponent:(NSInteger)component reusingView:(UIView *)view You could treat it as a passthrough (just passing back the reusingView parameter) but each time it was

EDIT 12-14-2015 : This problem is again frequently reported on iOS 7, iOS 8, iOS 9.... I think Apple want not of this control anymore, and should just forbid us to use it instead of let such a major bug I use a UIPickerView with custom views loaded from a Xib. I was using the method -(UIView *)pickerView:(UIPickerView *)pickerView viewForRow:(NSInteger)row forComponent:(NSInteger)component reusingView:(UIView *)view from UIPickerViewDelegate to reuse my views. With iOS 6, my UIPickerview works perfectly and my views are reused. Since iOS 7, the reusingView is always nil, so I need to load the

I have a customized UIPickerview and I do not want to use a datepicker. I want to implement the feature where when a user scrolls down/up the hours, the AM/PM component switches while the hour is scrolling. This means that I need to switch it before pickerView didSelectRow is called. Is there a way to do this? Thanks Use following method, - (void)pickerView:(UIPickerView *)pickerView didSelectRow:(NSInteger)row inComponent:(NSInteger)component { // put your logic here. } Above method is from UIPickerViewDelegate, If user selects any element using pickerview, this method is automatically

I have a UIPickerView on my UIView along with a UITextField . I am letting the user select a value from the picker or enter a custom value in the text field. When the user selects any option from the picker, the variable values are changed fine (in the pickerView:didSelectRow:inComponent: ) method. But if the user does not select any value on the picker (coz they want to select the 1st option which is already selected), this method is not called and the selection is not reflected in the variable. I tried setting the default value of the variable to the first option in the picker. But in that

How can I hide those 2 lines on the selected row? motox [[pickerview.subviews objectAtIndex:1] setHidden:TRUE]; [[pickerview.subviews objectAtIndex:2] setHidden:TRUE]; Use this in titleForRow or viewForRow delegate method of the pickerView . Based on the other answers, I decided to enumerate the subviews and saw that the lines have a height of 0.5 so my solution now looks like this in Swift: func numberOfComponentsInPickerView(pickerView: UIPickerView) -> Int { pickerView.subviews.forEach({ $0.hidden = $0.frame.height < 1.0 }) return myRowCount } And in Objective-C - (NSInteger
