我想要

  1. 显示选择器视图（向上滑动）
  2. 在可见时停用背景
  3. 在底部（而不是顶部）显示（UIActionSheet）按钮

起初在我看来这是一个简单的解决方案，因为您可以在网络上的任何地方找到将选择器视图添加到操作表的代码，但是所有解决方案都将按钮放在顶部，我需要将按钮放在操作表的底部（对齐？）。

这可能吗？我想如果我看一下：示例

UIActionSheet *actionSheet = [[UIActionSheet alloc] initWithTitle:nil
                                                             delegate:nil
                                                    cancelButtonTitle:nil
                                               destructiveButtonTitle:nil
                                                    otherButtonTitles:nil];
    [actionSheet setActionSheetStyle:UIActionSheetStyleBlackTranslucent];

    CGRect pickerFrame = CGRectMake(0, 0, 0, 0);
    UIPickerView *pickerView = [[UIPickerView alloc]initWithFrame:pickerFrame];
    pickerView.showsSelectionIndicator = YES;
    pickerView.dataSource = self;
    pickerView.delegate = self;

    UISegmentedControl *backButton =  [[UISegmentedControl alloc] initWithItems:[NSArray arrayWithObjects:@"Back", nil]] ;
    [backButton addTarget:self action:@selector(someFunction:) forControlEvents:UIControlEventValueChanged];
    backButton.tintColor = [UIColor colorWithRed:0.10 green:0.20 blue:0.52 alpha:0.5];
    backButton.segmentedControlStyle = UISegmentedControlStyleBar;
    [backButton addTarget:self action:@selector(btnActionCancelClicked:) forControlEvents:UIControlEventAllEvents];
    backButton.frame = CGRectMake(20.0, 220.0, 280.0, 40.0);

    UISegmentedControl *acceptButton =  [[UISegmentedControl alloc] initWithItems:[NSArray arrayWithObjects:@"Accept", nil]] ;
    [acceptButton addTarget:self action:@selector(anotherFunction:) forControlEvents:UIControlEventValueChanged];
    acceptButton.tintColor = [UIColor colorWithRed:0.10 green:0.20 blue:0.52 alpha:0.5];
    acceptButton.segmentedControlStyle = UISegmentedControlStyleBar;
    acceptButton.frame = CGRectMake(20.0, 280.0, 280.0, 40.0);

    [actionSheet addSubview:pickerView];
    [actionSheet addSubview:backButton];
    [actionSheet addSubview:acceptButton];

    [actionSheet showInView:[[UIApplication sharedApplication] keyWindow]];
    [actionSheet setFrame:CGRectMake(0,150,320, 400)];

...然后只需应用 iPhone 5/iphone 4 相关视图大小约束

编辑2： 只是另一个提示！最初我想使用标准的 Actionsheet，但不想将pickerview 放在底部。我没有找到如何移动按钮的方法。显然这很简单：在 UIActionSheet 上添加 UIView 作为 subView很高兴知道；）

您有 2 种可能性：

选项1：大调整。

ActionSheet 以在初始化期间定义的顺序显示按钮。所以在顶部放置一些虚拟按钮，取消将是唯一可见的，所有其他按钮将被选择器视图隐藏。代码（otherButtonTitles 的警告调整）：

UIActionSheet *menu = [[UIActionSheet alloc] initWithTitle:@"Actionsheet"
                                                  delegate:self
                                         cancelButtonTitle:@"Cancel"
                                    destructiveButtonTitle:nil
                                         otherButtonTitles:@"1", @"2", @"3", @"4", nil];

UIPickerView *pickerView = [[UIPickerView alloc] init];
pickerView.delegate = self;
pickerView.dataSource = self;

[menu addSubview:pickerView];
[menu showInView:self.view];
[menu setBounds:CGRectMake(0,0,320, 500)];

CGRect pickerRect = pickerView.bounds;
pickerRect.origin.y = 35;
pickerView.frame = pickerRect;

选项2：自制 

menu = [[UIActionSheet alloc] initWithTitle:@"Actionsheet"
                                                  delegate:self
                                         cancelButtonTitle:nil
                                    destructiveButtonTitle:nil
                                         otherButtonTitles:nil];

UIPickerView *pickerView = [[UIPickerView alloc] init];
pickerView.delegate = self;
pickerView.dataSource = self;
CGRect pickerRect = pickerView.bounds;
pickerRect.origin.y = 35;
pickerView.frame = pickerRect;

UIButton *startbtn = [UIButton buttonWithType:UIButtonTypeCustom];
startbtn.frame = CGRectMake(80,230, 170, 73);
[startbtn setBackgroundImage:[UIImage imageNamed:@"yourbutton.png"] forState:UIControlStateNormal];
[startbtn addTarget:self action:@selector(pressedbuttonCancel:) forControlEvents:UIControlEventTouchUpInside];

[menu addSubview:pickerView];
[menu addSubview:startbtn];
[menu showInView:self.view];
[menu setFrame:CGRectMake(0,150,320, 350)];

检查选项 2 的按钮是否应该在操作表上，除非点击不会被发送到选择器方法。
