Is it acceptable (aka would Apple consider it acceptable) to have a UIPickerView in a UIActionSheet?
Yes, It is totally acceptable. To some degree its even encouraged.
Example code: HERE by Erica Sadun in her book iPhone Developer's cookbook. Chapter 11 Recipe 21
Yes. It is acceptable.
set the frame of the UIPickerView
add the UIPickerView to the actionView
As I remember, actionView will be full screen in this case
UIActionSheet *actionView = [[UIActionSheet alloc] initWith...];
UIPickerView *pickerView = [UIPickerView alloc] init...];
pickerView.frame = CGRect(....);
[actionView addSubview:pickerView];
[pickerView release];
[actionView showInView:theView];
[actionView release];
This should do it :
NSString *title = #"\n\n\n\n\n\n\n\n\n\n\n\n"; // <--- Taken from Erica Sadun´s CookBook
UIActionSheet *actionSheet = [[UIActionSheet alloc] initWithTitle:title delegate:self cancelButtonTitle:nil destructiveButtonTitle:nil otherButtonTitles: nil];
[actionSheet setActionSheetStyle:UIActionSheetStyleBlackTranslucent];
[actionSheet setBounds:CGRectMake(0,0,320,485)];
UIPickerView *picker = [[UIPickerView alloc] initWithFrame:CGRectMake(0, 0, 320, 216)];
[picker setDataSource:self];
[picker setDelegate:self];
[picker setShowsSelectionIndicator:YES];
[actionSheet addSubview:picker];
[actionSheet showFromTabBar:[[self tabBarController] tabBar]];
Please remember that you have to set UIPickerView´s dataSource and delegate .

I'm trying to add a UIPickerVivew to a UIAlertController. I tried to do the following:
- (void)alertPickerView
{
UIActionSheet *actionSheet = [[UIActionSheet alloc] initWithTitle:#"Title" delegate:nil
cancelButtonTitle:nil
destructiveButtonTitle:nil
otherButtonTitles:nil, nil];
actionSheet.delegate = self;
UIPickerView *pickerView = [[UIPickerView alloc] initWithFrame:CGRectMake(0, 0, 320, 200)];
pickerView.delegate = self;
pickerView.showsSelectionIndicator = YES;
[actionSheet addSubview:pickerView];
}
When I called the method, the pickerView and actionSheet didn't come up.
(I would rather a UIAlertController, but if that's not possible, I'll go with a actionsheet.)
I have a UIActionSheet and I have added the following - UIPickerView and 2 BarButtonItems. I am trying to close the action sheet when someone clicks the Cancel Button (it is one of the bar button items).
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];
UIToolbar *tools = [[UIToolbar alloc]initWithFrame:CGRectMake(0, 0, 320, 40)];
tools.barStyle = UIBarStyleBlackOpaque;
[actionSheet addSubview:tools];
UIBarButtonItem *doneButton=[[UIBarButtonItem alloc]initWithTitle:#"Done" style:UIBarButtonItemStyleBordered target:self action:#selector(btnActinDoneClicked)];
doneButton.imageInsets=UIEdgeInsetsMake(200, 6, 50, 25);
UIBarButtonItem *CancelButton=[[UIBarButtonItem alloc]initWithTitle:#"Cancel" style:UIBarButtonItemStyleBordered target:self action:#selector(btnActinCancelClicked)]; //this is where the problem is
NSArray *array = [[NSArray alloc]initWithObjects:CancelButton, doneButton, nil];
[tools setItems:array];
[actionSheet showFromTabBar:self.tabBarController.tabBar];
[actionSheet setBounds:CGRectMake(0, 0, 320, 485)];
I have added another method to dismiss the action sheet -
-(IBAction)btnActinCancelClicked:(id)sender{
[sender dismissWithClickedButtonIndex:0 animated:YES];
}
The problem is that the app crashes when the BarButton is clicked. I think the problem is caused where the CancelButton is declared and it is unable to send a message to the btnActinCancelClicked method, but I can't figure out how to fix it.
Thanks
Your method is this;
-(IBAction)btnActinCancelClicked:(id)sender
So you need to add it like this (because it receives a parameter);
#selector(btnActinCancelClicked:)
So for example, if a method had three parameters you'd call it #selector(myMethod:andX:andY:)
Also, to access your UIActionSheet (not entirely sure this will work);
UIActionSheet *acSheet = sender.superView;
//Check if it is the ActionSheet here then dismiss it
[acSheet dismissWithClickedButtonIndex:0 animated:YES];
It's not the sender you want to dismiss. It's the ActionSheet. You'll need a reference for that and change your code for something like:
- (IBAction)btnActinCancelClicked:(id)sender{
[self.actionSheet dismissWithClickedButtonIndex:0 animated:YES];
}
Here's my implementation, I'm basically creating the action sheet and picker view on the fly. The problem is the indicator to show which item you have selected isn't showing.
UIActionSheet *actionSheet = [[UIActionSheet alloc] initWithTitle:title delegate:self cancelButtonTitle:#"Cancel" destructiveButtonTitle:nil otherButtonTitles:nil];
actionSheet.actionSheetStyle = UIActionSheetStyleDefault;
UIPickerView* picker = [[UIPickerView alloc] initWithFrame:CGRectMake(0,100, 320, 216)];
picker.dataSource = self;
picker.delegate = self;
[actionSheet addSubview:picker];
[actionSheet showInView:self.view];
[actionSheet setBounds:CGRectMake(0,0, 320, 411)];
It looks like you're missing this line:
[picker setShowsSelectionIndicator:YES];
I want to add a UIDatePicker to a UIActionSheet, the code is below:
UIActionSheet* actionSheet = [[UIActionSheet alloc] initWithTitle:#"DEMO" delegate:self cancelButtonTitle:#"Cancle" destructiveButtonTitle:nil otherButtonTitles:nil];
actionSheet = [[UIActionSheet alloc] initWithTitle:#"Ratings"
delegate:self
cancelButtonTitle:#"Cancel"
destructiveButtonTitle:nil
otherButtonTitles:nil];
UIDatePicker *pickerView = [[UIDatePicker alloc] init];
pickerView.datePickerMode = UIDatePickerModeDate;
[actionSheet addSubview:pickerView];
[actionSheet showInView:self.view];
[actionSheet sendSubviewToBack:pickerView];
[actionSheet showInView:self.view];
[actionSheet setBounds:CGRectMake(0,0,320, 500)];
CGRect pickerRect = pickerView.bounds;
pickerRect.origin.y = -100;
pickerView.bounds = pickerRect;
[pickerView release];
[actionSheet release];
The question is why this code cannot work in iPad mode while it is ok in iphone mode
I would try using EAActionSheetPicker. It handles that for you.
I want to add the feature that when i tap on a specific textfield, then there is a Dropdown / TableView in front of the gui and i can select a value and then the selected value is then inserted into the textfield?
How to achieve this in the easiest way?
Depends, if this is on the iPad, you can use UIPopoverController and present a UITableViewController inside it.
If not, you can present a UIActionSheet and add UIPickerView or a UITableView inside it...in this example, I am creating a UIActionSheet and placing a UIPickerView inside it:
NSString *title = UIDeviceOrientationIsLandscape([UIDevice currentDevice].orientation) ? #"\n\n\n\n\n\n\n\n\n" : #"\n\n\n\n\n\n\n\n\n\n\n\n" ;
UIActionSheet *actionSheet = [[UIActionSheet alloc]
initWithTitle:[NSString stringWithFormat:#"%#%#", title, [entry objectForKey:#"Name"]]
delegate:nil cancelButtonTitle:nil destructiveButtonTitle:nil otherButtonTitles:#"Ok", nil];
[actionSheet setDelegate:self];
[actionSheet setTag:row];
pv = [[UIPickerView alloc] init];
[pv setShowsSelectionIndicator:YES];
[pv setDelegate:self];
[pv setTag:28];
[actionSheet addSubview:pv];
[actionSheet showInView:[[[self navigationController] tabBarController] view]];
[pv release];
Notice the "\n"s, you need those to make room for the Picker view. Here's the result:
