Is it possible to create UIActionSheet buttons dynamically?

In this case, I'm trying to do the following:
NSMutableArray *btnAry = [[NSMutableArray alloc] init];
[btnAry addObject:@"button1"];
[btnAry addObject:@"button2"];
[btnAry addObject:@"button3"];
UIActionSheet *emailAction = [[UIActionSheet alloc] initWithTitle:title delegate:(id)self cancelButtonTitle:cancel destructiveButtonTitle:nil otherButtonTitles:btnAry];
The error I get here is: 'NSInvalidArgumentException', reason: '* -[NSCFArray length]: unrecognized selector sent to instance 0x459dd10'
I'm trying to basically create the action sheet based on the values in the array, which is dynamically set at runtime. I have tried using addButtonWithTitle, but the problem with this solution, is that I cannot specify the index of the cancel button without writing some hokie code...
It seems the easiest way would be to be able to somehow setup the UIActionSheet on init with the values for the buttons.
any thoughts on how to achieve this would be much appreciated....

   I have used following code to create radio button dynamically. but it's getting dump saying that Could not find attribute STATUS.
Here STATUS is the attribute of the node in View context. But why this dump is coming.
Please correct me if any thing worng.
DATA: lr_radio TYPE REF TO cl_wd_radiobutton.
DATA: lr_containr TYPE REF TO cl_wd_transparent_container.
DATA: lr_data TYPE REF TO cl_wd_flow_data.
IF first_time = abap_true.
    lr_containr ?= view->get_element( 'ROOTUIELEMENTCONTAINER' ).
    lr_radio = cl_wd_radiobutton=>new_radiobutton(
    view = view
    id = 'RADIO'
    text = 'Enroll'

Thank you very much

Hi Rama,
I solved it.check this code.
i think u did mistake in creating radio button you are not passing the
BIND_KEY_TO_SELECT
instead you are passing KEY_TO_SELECT.
data:lr_column2 type ref to cl_wd_table_column,
     lr_radio type ref to cl_wd_radiobutton.
   lr_column2 = obj_table->get_column(
               id         = 'TABLE1_PLANETYPE'
*              INDEX      = INDEX
lr_radio = cl_wd_radiobutton=>new_radiobutton(

Is it possible to create a button which goes back to the previous page?

I would like to create a button which sits within a interactive pdf page that on click will return me to my previously visited page.
As the page will be able to be accessed via numerous other pages the traditional built in Execute menu action is not suitable.
The page which will be displayed (on click of a button) is a series of mattress sizes which i want to be accessable by each bed product in our collection. Once the user has looked at the mattress size guide i want them to be able to return to the bed product that they were looking at originally, without having to then scroll and search.
Is this possible with some javascript trickery?
i found this script:
history.go(-1);
But allas acrobat was not fond of it.
PLEASE HELP!
Thanks in advance.

PDFs are not HTML documents. HTML has no concept of a physical page and PDF only knows a page canvas.
You can access the page number property of the doc object and you can set the page number of the page number of the doc object. The page number in Acrobat JavaScript is zero base, the first page is 0.
To get the page number one uses the following code:
this.pageNum;
To set the page number one uses:
this.pageNum = 0; // goto first page
To goto the next page:
this.pageNum = this.pageNum++ // increment the page number and goto that page
To goto the last page:
this.pageNum = this.numPages--; // decrement the total number of pages
To goto the previous page:
this.pageNum = this.pageNum--; // decrement the page number

Edit button in uitableview (possible to create custom buttons)

Hi
Instead of Edit button in the UiTableView, we can create a custom buttons. Basically once we clicked the edit button it shows the option (delete button) to delete the corresponding row.
Like that is it possible to create a custom button? Clicked on custom button, instead of delete button can we show other buttons (ok/cancel), rather than delete we can do any other action?
Thanks

Is it possible to create a button animation on 'highlight'?

I've created my menu in Photoshop and I would like to have my polaroid buttons move slightly/wiggle when 'highlighted', not necessarily selected. Is there a way to create these animations in After Effects and integrate them into Encore?
If not, is there a way to have the video buttons not begin playing until highlighted?
Any help would be grately appreciated! Thank you very much!
Erin

Not directly, but you can try the following. You can use autoactivate to go to a different menu that has the "selected" picture in motion. You have six pictures, so you have the original (all still menu), then 6 more, each with a different motion background in which the picture moves. All buttons are able to be clicked in every menu.
This works in a DVD, but not on a computer, unless the user uses a remote type function. (Mouse over won't autoactivate.)

Hi guys, This is very urgent, Creating radio button dynamically.

Hi guys,
I have this requirement where i need to access a table and depending on the possible answers for that question i need to display radio buttons on the next screen.
lets say if i have the possible answers as YNX. i have to display three radio buttons besides the text one for YES, one for NO, one for N/A. I know this is kind of tricky but one more thing. if the possible answers are YN then i shud only have 2 radiobuttons one YES, one NO.
and there are not only one text that im printing but there are multiple texts and radio buttons for each of them besides it.
its urgent,
Thanks

Can you create a button that adds specific text to a form field?

Hi,
I was wondering if it was possible to create a button in a PDF that, when clicked, adds specific text to a form field?
I am trying to make a product catalogue where you click on a product button to add the product name or code to a form field.
Each product in the catalogue will have a button and the more you click the more is added to the form field(s).
Then when you have finished adding products to the form field(s) I want to be able to save and email the entire PDF as an order form.
Any thoughts would be appreciated!
Cheers,
Jim

Yes, it's possible. The most simple version of such a script will be something like this (used as the button's MouseUp event):
var v = this.getField("Products");
if (f.value!="")
f.value += ", ";
f.value += "Product1";

Create a Table Dynamically in WEB Dynpro Java with diferent type of column

Thank you everyone
Atte Israel

Hello,Israel.
Yes , it is possible through dynamic programming in wdModify of the View.
You can do this ,for example, using cell variants.
IWDTable tab = (IWDTable) view.getElement("TABLE_NAME");
IWDTableStandardCell cellV= (IWDTableStandardCell) view.createElement(IWDTableStandardCell.class,"TableStandardCell"+i);
cellV.setVariantKey("NotEditableVariant");
cellV.setCellDesign((WDTableCellDesign)wdContext.nodeTableDaysTitle().currentTableDaysTitleElement().getAttributeValue("CellDesign"+i));
IWDTextView textViewi= (IWDTextView) view.createElement(IWDTextView.class,"TextView"+i); // -- here you control the type of the object that is displayed in the cell
textViewi.bindText(dayAttrib);
cellV.setEditor(textViewi);
tabColumn.addCellVariant(cellV);
tab.addGroupedColumn(tabColumn,tab.numberOfGroupedColumns());
Using this code you can control even specific cells in the table and not only columns.
Hope this helps you,
Constantine
