通过传入数组而不是varlist来创建UIActionSheet的“otherButtons” [英] Create UIActionSheet 'otherButtons' by passing in array, not varlist

问题描述

我有一个字符串数组，我想用于UIActionSheet上的按钮标题。不幸的是，方法调用中的otherButtonTitles：参数采用可变长度的字符串列表，而不是数组。

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.

那么我怎么能将这些标题传递给UIActionSheet？我见过的解决方法是将nil传递给otherButtonTitles :,然后使用addButtonWithTitle：单独指定按钮标题。但这有将取消按钮移动到UIActionSheet上的第一个位置而不是最后一个位置的问题;我希望它是最后一个。

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.

有没有办法1）传递一个数组来代替变量的字符串列表，或者2）移动取消UIActionSheet底部的按钮？

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?

谢谢。

推荐答案

我得到了这个工作（你只需要，可以使用常规按钮，然后在以下后添加：

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];
