Question

我正在尝试使用UIButton获取UIDatePicker以显示在UIActionSheet中。不幸的是，它被裁掉了，整个日期选择器都不可见。我还没有尝试过添加UIButton。任何人都可以建议让整个视图适合吗？我不确定如何添加适当的尺寸，因为UIActionSheet似乎缺少-initWithFrame:类型的构造函数。

UIActionSheet *menu = [[UIActionSheet alloc] initWithTitle:@"Date Picker" 
                                                  delegate:self
                                         cancelButtonTitle:@"Cancel"
                                    destructiveButtonTitle:nil
                                         otherButtonTitles:nil];

// Add the picker
UIDatePicker *pickerView = [[UIDatePicker alloc] init];
pickerView.datePickerMode = UIDatePickerModeDate;
[menu addSubview:pickerView];
[menu showInView:self.view];

[pickerView release];
[menu release];

我也试过类似的东西：

UIActionSheet *menu = [[UIActionSheet alloc] initWithFrame:CGRectMake(200.0, 200.0, 100.0f, 100.0f)];

coords是不现实的，但它们似乎不会影响UIActionSheet的位置/大小。

Answer 1

你可以使用这样的东西（调整坐标）：

    UIActionSheet *menu = [[UIActionSheet alloc] initWithTitle:@"Date Picker" 
                                                  delegate:self
                                         cancelButtonTitle:@"Cancel"
                                    destructiveButtonTitle:nil
                                         otherButtonTitles:nil];

    // Add the picker
    UIDatePicker *pickerView = [[UIDatePicker alloc] init];
    pickerView.datePickerMode = UIDatePickerModeDate;
    [menu addSubview:pickerView];
    [menu showInView:self.view];    
    [menu setBounds:CGRectMake(0,0,320, 500)];

    CGRect pickerRect = pickerView.bounds;
    pickerRect.origin.y = -100;
    pickerView.bounds = pickerRect;

    [pickerView release];
    [menu release];

但您最好使用UIDatePicker和导航栏创建全屏视图。有关示例，请参阅UICatalog - ＆gt;拾取器样品来自iPhone DevCenter。

尝试添加以下行以解决已禁用的按钮问题

[menu sendSubviewToBack:pickerView];

Answer 3

德米特里的答案几乎正确。但是，动作表的框架太小，因此忽略了拾取器底部附近的触摸。我纠正了这些问题：

UIActionSheet *menu = [[UIActionSheet alloc] initWithTitle:@"Date Picker" 
                                                  delegate:self
                                         cancelButtonTitle:@"Cancel"
                                    destructiveButtonTitle:nil
                                         otherButtonTitles:@"OK",nil];    
// Add the picker
UIDatePicker *pickerView = [[UIDatePicker alloc] init];
pickerView.datePickerMode = UIDatePickerModeTime;
[menu addSubview:pickerView];
[menu showInView:_mainView];        

CGRect menuRect = menu.frame;
CGFloat orgHeight = menuRect.size.height;
menuRect.origin.y -= 214; //height of picker
menuRect.size.height = orgHeight+214;
menu.frame = menuRect;


CGRect pickerRect = pickerView.frame;
pickerRect.origin.y = orgHeight;
pickerView.frame = pickerRect;

[pickerView release];
[menu release];

Answer 4

这对我有用

NSString *title = UIDeviceOrientationIsLandscape([UIDevice currentDevice].orientation) ? @"\n\n\n\n\n\n\n\n\n" : @"\n\n\n\n\n\n\n\n\n\n\n\n" ;
UIActionSheet *actionSheet = [[UIActionSheet alloc] 
                              initWithTitle:[NSString stringWithFormat:@"%@%@", title, NSLocalizedString(@"SelectADateKey", @"")]
                              delegate:self cancelButtonTitle:nil destructiveButtonTitle:nil otherButtonTitles:@"Ok", nil];
[actionSheet showInView:self.view];
UIDatePicker *datePicker = [[[UIDatePicker alloc] init] autorelease];
datePicker.datePickerMode = UIDatePickerModeDate;
[actionSheet addSubview:datePicker];

有点棘手但有效！

顶部的按钮，底部的选择器：

 UIActionSheet *menu = [[UIActionSheet alloc] initWithTitle:@"Date Picker" 
                                                  delegate:self
                                         cancelButtonTitle:@"Cancel"
                                    destructiveButtonTitle:nil
                                         otherButtonTitles:@"OK",nil];    
// Add the picker
UIDatePicker *pickerView = [[UIDatePicker alloc] init];
pickerView.datePickerMode = UIDatePickerModeTime;
[menu addSubview:pickerView];
[menu showInView:_mainView];        

CGRect menuRect = menu.frame;
menuRect.origin.y -= 214;
menuRect.size.height = 300;
menu.frame = menuRect;


CGRect pickerRect = pickerView.frame;
pickerRect.origin.y = 174;
pickerView.frame = pickerRect;

[pickerView release];
[menu release];

Answer 6

确保在UITabBarController内部的右视图中显示UIActionSheet，以避免底部的交互问题：

[actionSheet showInView:self.parentViewController.tabBarController.view];

Answer 7

可能没有直接回答具体问题（如何使UIDatePicker适合），但是对于UIAatePicker（也是其他人）的UIActionSheet的实现，请参阅ActionSheetPicker。从它的自述文件：

使用PickerView轻松呈现ActionSheet，允许用户从多个不可变选项中进行选择。基于mobilesafari中的HTML下拉选项。

此外：

一些代码源自Marcio发布的Stack Overflow [Add UIPickerView & a Button in Action sheet - How?]

即使一个人不使用该代码，在你自己动手之前阅读也是很好的。

不推荐使用此版本：改为使用ActionSheetPicker-3.0。
