添加UIPickerView到UIActionSheet（在底部按钮）(Adding UIPicke

我想要

1. 示出了选择器视图（向上滑动）
2. 停用背景而它的可见
3. 显示（UIActionSheet）按钮在底部（未在顶部）

在我看来，首先一个简单的解决方案，因为你可以在网页，但所有的解决方案位置到处添加选择器以一个动作片，在顶部的按钮找到代码， 我需要把按钮的动作片的底部（对齐？）。

这可能吗？ 我想这是，如果我看： 实例

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)]; 

......那么就适用iPhone 5 / iPhone 4的依赖视角大小限制

组织编写了：又一个暗示！ 本来我想用标准Actionsheet，但并没有要放置pickerview底部。 我没有找到一个方法如何移动的按钮。 显然，这真的很简单： 添加的UIView作为子视图的UIActionSheet好知道;）

Answer 1:

你有2个possibilites：

选项1：大的调整。

ActionSheet示出了具有初始化期间定义的次序的按钮。 因此，在顶部位置放置一些虚拟按钮和取消将是唯一可见的，其他所有按钮将被pickerview隐藏。 代码（警告-TWEAK在otherButtonTitles）：

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：在自制

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)];

检查为1选项按钮应在actionsheet除非点击将不会被派往选择方法。
