将UIDatePicker安装到UIActionSheet中 [英] Fitting a UIDatePicker into a UIActionSheet

问题描述

我试图得到一个UIDatePicker与UIButton出现在UIActionSheet。不幸的是，它被裁剪掉，整个日期选择器不可见。我还没有尝试添加UIButton。任何人都可以建议让整个视图适当地适合？我不知道如何添加正确的维度，因为UIActionSheet似乎缺少一个 -initWithFrame：类型构造函数。

I'm trying to get a UIDatePicker with a UIButton to show up in a UIActionSheet. Unfortunately it gets cropped off and the entire Date Picker is not visible. I have not even attempted to add the UIButton yet. Can anyone suggest on getting the entire view to fit properly? I'm not sure how to add the proper dimensions as UIActionSheet seems to lack an -initWithFrame: type constructor.

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：

I've also tried with something similar to:

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

坐标是不现实的，但它们似乎不影响位置/大小UIActionSheet。

The coords are ofcourse not realistic, but they don't seem to affect the position/size of the UIActionSheet.

推荐答案

您可以使用这样的东西（调整坐标）：

You can use something like this (adjust the coordinates):

    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];

但是最好使用UIDatePicker和导航栏创建一个全屏视图。有关示例，请参阅iPhone DevCenter中的UICatalog - > Pickers示例。

But you better create a fullscreen view with a UIDatePicker and a navigation bar. For an example see UICatalog -> Pickers sample from the iPhone DevCenter.
