UIPickerView with a Done button in Ipad

Question

I have faced one issue to display UIPickerView with a Done button in Ipad. I done detailed researches though many links and blogs and got the suggestion as "display the UIPickerView from an UIActionSheet"

I saw many posts related this, however there is no good answers.So please dont close it as a duplicate.

Also i was able to get some good codes to do it and it worked fine in my Iphone devices. However i were found a difficulty in Ipad devices. The Action-Sheet is not displaying as a full view. Please see the below screenshot.this was the result!!!

UIPickerView with a Don button in Ipad

The code is used to do this is pasted below.

UIActionSheet *actionSheet = [[UIActionSheet alloc] initWithTitle:nil
                                                    delegate:nil
                                                    cancelButtonTitle:nil
                                                    destructiveButtonTitle:nil
                                                    otherButtonTitles:nil];

[actionSheet setActionSheetStyle:UIActionSheetStyleBlackTranslucent];

CGRect pickerFrame = CGRectMake(0, 40, 0, 0);

UIPickerView *pickerView = [[UIPickerView alloc] initWithFrame:pickerFrame];
pickerView.showsSelectionIndicator = YES;
pickerView.dataSource = self;
pickerView.delegate = self;

[actionSheet addSubview:pickerView];
[pickerView release];

UISegmentedControl *closeButton = [[UISegmentedControl alloc] initWithItems:[NSArray arrayWithObject:@"Close"]];
closeButton.momentary = YES;
closeButton.frame = CGRectMake(260, 7.0f, 50.0f, 30.0f);
closeButton.segmentedControlStyle = UISegmentedControlStyleBar;
closeButton.tintColor = [UIColor blackColor];
[closeButton addTarget:self action:@selector(dismissActionSheet:) forControlEvents:UIControlEventValueChanged];
[actionSheet addSubview:closeButton];
[closeButton release];

[actionSheet showInView:[[UIApplication sharedApplication] keyWindow]];

[actionSheet setBounds:CGRectMake(0, 0, 320, 485)];

Then I have downloaded a excellent sample application from github through sample pickers

After the download, i have copied the classes only mandatory for me to my application.

The method they are using to show the UIPickerView+Done button through Action-Sheet is described below

ActionStringDoneBlock done = ^(ActionSheetStringPicker *picker, NSInteger selectedIndex, id selectedValue) {

        if ([myLabel respondsToSelector:@selector(setText:)]) {
            [myLabel performSelector:@selector(setText:) withObject:selectedValue];
        }
    };

    ActionStringCancelBlock cancel = ^(ActionSheetStringPicker *picker) {

        NSLog(@"Block Picker Canceled");
    };

    NSArray *colors = [NSArray arrayWithObjects:@"Red", @"Green", @"Blue", @"Orange", nil];//picker items to select


    [ActionSheetStringPicker showPickerWithTitle:@"Select a Block" rows:colors initialSelection:0 doneBlock:done cancelBlock:cancel origin:myButton];

In the last line of code they have used the parameter as origin: and we can pass any objects (button,label etc) to it.

The Action-sheet will take origin as the passed object.

Here my issue came again :). I have used segment control to pick the time as per my conditions.

if i give mySegment as the origin parameter,the Action-sheet origin arrow will display from middle of my segment control.Not from the selected tab ,which is too bad and will give confusion to my valuable users.

So i have added individual labels under the segment sections and given it for the origin parameter of the mentioned method and i fixed my issue.

However i know its not a good fix :)

May i know is there any easy way to do it?

Is Apple support ActionSheet+UIPickerView+DoneButton in Ipad?

Any help on this issue is Appreciated

iphone support only uiactiosheet . and ipad only support uipopovercontroller. — ChintaN -Maddy- Ramani, Jun 22 '12 at 04:53

Use UIPopoverController for done button in picker, create a view controller class in which take a picker and add navigation cancel and done button.

    UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:nextViewController];
    _datePickerPopover = [[UIPopoverController alloc] initWithContentViewController:navigationController];
    nextViewController.datePickerPopover = _datePickerPopover;
    _datePickerPopover.delegate=self;
    [_datePickerPopover setPopoverContentSize:CGSizeMake(320, 453) animated:NO];
    if (isSearchOpen) {
        [_datePickerPopover presentPopoverFromRect:CGRectMake(btn.frame.origin.x+10+245, btn.frame.origin.y+100-scrollPointY, 44, 44) inView:self.splitViewController.view permittedArrowDirections:UIPopoverArrowDirectionLeft animated:YES];  
    }
    else
    {
        [_datePickerPopover presentPopoverFromRect:CGRectMake(btn.frame.origin.x+10+245, btn.frame.origin.y+55, 44, 44) inView:self.splitViewController.view permittedArrowDirections:UIPopoverArrowDirectionLeft animated:YES];//
    }

You have to use UIPopOverController.

First, create a UIPickerViewController for iPhone. You need it for the nib, which will be pushed into the popOver. Initialize the picker in ViewWithPicker

.h

#import <UIKit/UIKit.h>

@class ViewWithPickerController;

@protocol PopoverPickerDelegate

@required

- (void) viewWithPickerController:(ViewWithPickerController*) viewWithPickerController didSelectValue:(NSString*) value;

@end

@interface ViewWithPickerController : UIViewController <UIPickerViewDelegate, UIPickerViewDataSource> {
    IBOutlet UIPickerView *pickerView;
    id<PopoverPickerDelegate> delegate;
    NSMutableArray *array;  
}
@property(nonatomic, retain) IBOutlet UIPickerView *pickerView;
@property(nonatomic, assign) id<PopoverPickerDelegate> delegate;
@end

.m, after you initialized the array in viewDidLoad, picker methods:

// returns the number of 'columns' to display.
- (NSInteger)numberOfComponentsInPickerView:(UIPickerView *)picker {
    return 1;
}

// returns the number of rows in each component.


- (NSInteger)pickerView:(UIPickerView *)picker numberOfRowsInComponent:(NSInteger)component {
    return [array count];
}

//returns the string value for the current row
- (NSString *)pickerView:(UIPickerView *)picker titleForRow:(NSInteger)row forComponent:(NSInteger)component {
   return [array objectAtIndex:row];
}

//handle selection of a row
- (void)pickerView:(UIPickerView *)picker didSelectRow:(NSInteger)row inComponent:(NSInteger)component {
    NSString *value = [pickerView.delegate pickerView:picker titleForRow:row forComponent:component];

    //notify the delegate about selecting a value
    if(delegate != nil)
        [delegate viewWithPickerController:self didSelectValue:value];
}

Then, import the viewWithPicker into your main class, create a button and give it this action:

- (IBAction) showPickerPopupAction:(id) sender {
    self.viewWithPickerController = [[[ViewWithPickerController alloc] initWithNibName:@"ViewWithPicker" bundle:[NSBundle mainBundle]] autorelease];


    viewWithPickerController.contentSizeForViewInPopover = 
    CGSizeMake(viewWithPickerController.view.frame.size.width, viewWithPickerController.view.frame.size.height);

    viewWithPickerController.delegate = self;

    self.popoverController = [[[UIPopoverController alloc]
                               initWithContentViewController:viewWithPickerController] autorelease];


    [self.popoverController presentPopoverFromRect:popoverButtonForPicker.frame inView:self.view permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
    popoverController.delegate = self;

}

And to select a specific value

- (void) viewWithPickerController:(ViewWithPickerController*) viewWithPickerController didSelectValue:(NSString*) value
{   
    yourLabel.text = [NSString stringWithFormat:@"%@ ",value];

}

Try out below code for UIPicker View in iPad

-(IBAction)tDriveBtnPressed:(id)sender
{
NSDateFormatter *df = [[NSDateFormatter alloc] init];
df.dateStyle = NSDateFormatterMediumStyle;
txtDate.text = [NSString stringWithFormat:@"%@",
                [df stringFromDate:[NSDate date]]];
[df release];

UIToolbar *pickerToolbar = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 0, 300, 44)];
pickerToolbar.barStyle = UIBarStyleBlackOpaque;
[pickerToolbar sizeToFit];
NSMutableArray *barItems = [[NSMutableArray alloc] init];
UIBarButtonItem *doneBtn = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemDone target:self action:@selector(pickerDone:)];
[barItems addObject:doneBtn];
[doneBtn release];
[pickerToolbar setItems:barItems animated:YES];
[barItems release];

datePicker = [[UIDatePicker alloc] init];
datePicker.datePickerMode = UIDatePickerModeDate;

CGRect pickerRect = datePicker.bounds;
datePicker.bounds = pickerRect;

UIViewController* popoverContent = [[UIViewController alloc] init];
UIView* popoverView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 320, 344)];
popoverView.backgroundColor = [UIColor whiteColor];

datePicker.frame = CGRectMake(0, 44, 320, 300);
[datePicker addTarget:self action:@selector(dateChange:) forControlEvents:UIControlEventValueChanged];
[popoverView addSubview:pickerToolbar];
[popoverView addSubview:datePicker];
popoverContent.view = popoverView;

//resize the popover view shown
//in the current view to the view's size
popoverContent.contentSizeForViewInPopover = CGSizeMake(320, 244);

//create a popover controller
popoverController = [[UIPopoverController alloc] initWithContentViewController:popoverContent];
CGRect popoverRect = [self.view convertRect:[tDriveBtn frame] 
                                   fromView:[tDriveBtn superview]];

popoverRect.size.width = MIN(popoverRect.size.width, 100) ; 
popoverRect.origin.x  = popoverRect.origin.x; 
// popoverRect.size.height  = ; 

[popoverController 
 presentPopoverFromRect:popoverRect
 inView:self.view 
 permittedArrowDirections:UIPopoverArrowDirectionAny
 animated:YES];


//release the popover content
[popoverView release];
[popoverContent release];

}
-(void)dateChange:(id)sender
{
NSDateFormatter *df = [[NSDateFormatter alloc] init];
df.dateStyle = NSDateFormatterMediumStyle;
txtDate.text= [NSString stringWithFormat:@"%@",
               [df stringFromDate:datePicker.date]];
[df release];
}
- (void)pickerDone:(id)sender
{
NSDateFormatter *df = [[NSDateFormatter alloc] init];
df.dateStyle = NSDateFormatterMediumStyle;
txtDate.text= [NSString stringWithFormat:@"%@",
               [df stringFromDate:datePicker.date]];
[df release];

if (popoverController != nil) {
    [popoverController dismissPopoverAnimated:YES];
    self.popoverController=nil;
}  
}
