How to get pickervalue from action sheet in iOS? - ios

Question

In my app, when button is pressed, I am launching UIActionSheet with UIPickerView and UIToolBar in it. Its working perfectly by using the following code. I am trying to get the picker value and set that value to the called button, but I couldn't find the exact solution for it.
- (IBAction)showPicker:(id)sender {
actionSheet = [[UIActionSheet alloc] initWithTitle:nil
delegate:self
cancelButtonTitle:nil
destructiveButtonTitle:nil
otherButtonTitles:nil];//as we want to display a subview we won't be using the default buttons but rather we're need to create a toolbar to display the buttons on
[actionSheet setActionSheetStyle:UIActionSheetStyleBlackTranslucent];
CGRect pickerFrame = CGRectMake(0, 40, 0, 0);
pickerView = [[UIPickerView alloc] initWithFrame:pickerFrame];
pickerView.showsSelectionIndicator = YES;
pickerView.dataSource = self;
pickerView.delegate = self;
[actionSheet addSubview:pickerView];
//[pickerView release];
pickerToolbar = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 0, 320, 44)];
pickerToolbar.barStyle = UIBarStyleBlackOpaque;
[pickerToolbar sizeToFit];
NSMutableArray *barItems = [[NSMutableArray alloc] init];
UIBarButtonItem *flexSpace = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:self action:nil];
[barItems addObject:flexSpace];
UIBarButtonItem *doneBtn = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemDone target:self action:#selector(doneButtonPressed:)];
[barItems addObject:doneBtn];
UIBarButtonItem *cancelBtn = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemCancel target:self action:#selector(cancelButtonPressed:)];
[barItems addObject:cancelBtn];
[pickerToolbar setItems:barItems animated:YES];
[actionSheet addSubview:pickerToolbar];
[actionSheet addSubview:pickerView];
[actionSheet showInView:self.view];
[actionSheet setBounds:CGRectMake(0, 0, 320, 485)];
}
When Done button in Tool bar pressed it will call this method
-(void)doneButtonPressed:(id)sender{
//Do something here here with the value selected using [pickerView date] to get that value
[actionSheet dismissWithClickedButtonIndex:1 animated:YES];
[pickerView release];
[pickerToolbar release];
[actionSheet release];
}
Here is my questions
How to get The picker value from action sheet?
How to set that value to the button?
Thanks for your help guys

Answer 1

Assuming the pickerView datasource has only one component you can get the selected row using:
NSInteger row = [pickerView selectedRowInComponent:0];

Answer 2

Just create one ivar in your .h or .m and assign the [pickerView date] to the ivar and you are done with getting the value from ActionSheet.
Happy Coding :)
EDIT
in your -(void)doneButtonPressed:(id)sender method just put this line of code
selected = [pickerView date];
And selected is the NSDate type ivar declared in .h as below
#property (strong, nonatomic) NSDate *selected;
And have to declare one property for datePicker also
#property (strong, nonatomic) UIDatePicker *pickerView;
And in .m synthesize it as below
#synthesize pickerView;
#synthesize selected;
Happy Coding :)
Edit 1
For custom pickerView
(I assume that all the delegate and datasources for pickerView is defined and declared)
to get selected value from custom picker have to use the below mentioned code
NSInteger row = [singlePicker selectedRowInComponent:0];
NSString *selected = [pickerData objectAtIndex:row];
singlePicker = pickerView and pickerData is NSArray which is used as datasource for pickerView
May this will help you to solve your problem.
Happy Coding :)
