将UIPickerView添加到UIActionSheet（底部的按钮）

Question

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

一开始我觉得这是一个简单的解决方案，因为您可以找到代码以在Web上的任何地方向操作表添加选择器视图，但是所有解决方案都将按钮置于顶部，而我需要将按钮置于操作表的底部（对齐？） 。

这可能吗？ 我想是这样的： 示例

编辑（我的解决方案基于已编码的父亲解决方案）

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：另一个提示！ 最初，我想使用标准的Actionsheet，但不想将pickerview放在底部。 我没有找到一种方法来移动按钮。 显然，这非常简单： 在UIActionSheet上将UIView添加为subView很高兴知道;）

Answer 1

您有2种可能性：

选项1：大调整。

ActionSheet显示按钮以及在初始化期间定义的顺序。 因此，将一些虚拟按钮放在顶部，“取消”将是唯一可见的，而其他所有按钮将被pickerview隐藏。 代码（在otherButtonTitles上进行警告调整） ：

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，除非单击不会被分派到选择器方法。
