将UIDatePicker拟合到UIActionSheet中

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];

我也尝试过类似的东西:

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

这些坐标是不现实的,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iPhone DevCenter中的UICatalog - > Pickers示例.

尝试添加以下行以解决已禁用的按钮问题

[menu sendSubviewToBack:pickerView];

Answer 3

德米特里的回答几乎是正确的.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];

这适合我

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,但它的工作原理!

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];
