Create UIActionSheet 'otherButtons' by passing in array, not varlist - ios

Question

I have an array of strings that I want to use for button titles on a UIActionSheet. Unfortunately, the otherButtonTitles: argument in the method invocation takes a variable length list of strings, not an array.
So how I can I pass these titles into the UIActionSheet? The workaround I've seen suggested is to pass nil into otherButtonTitles:, then specify the button titles individually by using addButtonWithTitle:. But this has the problem of moving the "Cancel" button to the first position on the UIActionSheet rather than the last; I want it to be the last one.
Is there a way to 1) pass an array in lieu of a variable list of strings, or alternatively 2) move the cancel button to the bottom of the UIActionSheet?
Thanks.

Answer 1

I got this to work (you just need to, be ok with a regular button, and just add it after :
NSArray *array = #[#"1st Button",#"2nd Button",#"3rd Button",#"4th Button"];
UIActionSheet *actionSheet = [[UIActionSheet alloc] initWithTitle:#"Title Here"
delegate:self
cancelButtonTitle:nil
destructiveButtonTitle:nil
otherButtonTitles:nil];
// ObjC Fast Enumeration
for (NSString *title in array) {
[actionSheet addButtonWithTitle:title];
}
actionSheet.cancelButtonIndex = [actionSheet addButtonWithTitle:#"Cancel"];
[actionSheet showInView:self.view];

One little note: [actionSheet addButtonWithTitle:] returns the index of that button, so to be safe and "clean" you can do this:
actionSheet.cancelButtonIndex = [actionSheet addButtonWithTitle:#"Cancel"];

Answer 3

Taking Jaba's and Nick's answers and extending them a little further. To incorporate a destruction button into this solution:
// Create action sheet
UIActionSheet *actionSheet = [[UIActionSheet alloc] initWithTitle:title
delegate:self
cancelButtonTitle:nil
destructiveButtonTitle:nil
otherButtonTitles:nil];
// Action Buttons
for (NSString *actionName in actionNames){
[actionSheet addButtonWithTitle: actionName];
}
// Destruction Button
if (destructiveName.length > 0){
[actionSheet setDestructiveButtonIndex:[actionSheet addButtonWithTitle: destructiveName]];
}
// Cancel Button
[actionSheet setCancelButtonIndex: [actionSheet addButtonWithTitle:#"Cancel"]];
// Present Action Sheet
[actionSheet showInView: self.view];

Answer 4

There is the swift version for the response :
//array with button titles
private var values = ["Value 1", "Value 2", "Value 3"]
//create action sheet
let actionSheet = UIActionSheet(title: nil, delegate: self, cancelButtonTitle: nil, destructiveButtonTitle: nil)
//for each value in array
for value in values{
//add a button
actionSheet.addButtonWithTitle(value as String)
}
//display action sheet
actionSheet.showInView(self.view)
To get value selected, add delegate to your ViewController :
class MyViewController: UIViewController, UIActionSheetDelegate
And implement the method "clickedButtonAtIndex"
func actionSheet(actionSheet: UIActionSheet, clickedButtonAtIndex buttonIndex: Int) {
let selectedValue : String = values[buttonIndex]
}
