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

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

Answer 1

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]
}

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];

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"];
