ios - 从添加到 UIAlertViewController 的 UIAlertAction 表中获取选定的按钮标题

Question

我使用 Objective-C 创建了操作表。当我想获取选定的按钮标题时，我卡住了。请帮我。(我知道有一个委托(delegate)方法可以获取 Action 的标题。但它在 iOS 8.0+ 中已被弃用。)这是我的代码。我的要求是获取选定的标题并将其更新为文本字段。

NSArray *subjectType = [NSArray arrayWithObjects:@"Customer Service",@"Product Info",@"Deals",@"Special",@"Others", nil];

    UIAlertController *subjectSheet = [UIAlertController alertControllerWithTitle:@"Subjects" message:@"Select a prefered subject" preferredStyle:UIAlertControllerStyleActionSheet];


    for (int i=0; i<subjectType.count; i++) {
        UIAlertAction *myalertAction = [UIAlertAction actionWithTitle:[subjectType objectAtIndex:i] style:UIAlertActionStyleDefault handler:^(UIAlertAction *action) {

        }];


    [subjectSheet addAction:myalertAction];
}

试试UIAlertAction的title属性

 UIAlertController * alert = [UIAlertController alertControllerWithTitle:@"Title"
                                                               message:@"message"
                                                        preferredStyle:UIAlertControllerStyleActionSheet];
[alert addAction:[UIAlertAction actionWithTitle:@"OK"
                                          style:UIAlertActionStyleDefault handler:^(UIAlertAction *action) {
                                              NSLog(@"%@",action.title);
                                          }]];
[self presentViewController:alert animated:true completion:nil];
