我正在尝试在iPad中显示操作表,其中包含2个按钮和日期选择器视图。
我在iphone中正确显示了操作表,但当我尝试在iPad中显示操作表时,它只显示一条粗黑线。
目前看起来像:
显示操作表的代码是
UIButton *btnClicked=(UIButton *)sender;
menu = [[UIActionSheet alloc] initWithTitle:nil
delegate:self
cancelButtonTitle:nil
destructiveButtonTitle:nil
otherButtonTitles:nil];
/* menu=[[UIActionSheet alloc] initWithTitle:@"This will remove this recipe from all synced devices as well. Are you sure?" delegate:self cancelButtonTitle:@"Cancel" destructiveButtonTitle:@"Confirm Delete Recipe" otherButtonTitles:nil];*/
[menu setTag:121];
UILabel *titleLabel = [[UILabel alloc] initWithFrame:CGRectMake(10,5,300,20)];
[titleLabel setFont:[UIFont fontWithName:@"Trebuchet MS" size:18.0f]];
titleLabel.textAlignment = UITextAlignmentCenter;
titleLabel.backgroundColor = [UIColor clearColor];
titleLabel.textColor = [UIColor whiteColor];
[titleLabel setNumberOfLines:1];
[menu addSubview: titleLabel];
UIButton *cancelButton = [UIButton buttonWithType: UIButtonTypeCustom];
cancelButton.frame = CGRectMake(30, 30, 124, 43);
[cancelButton setBackgroundImage:[UIImage imageNamed:@"cancel_button.png"] forState: UIControlStateNormal];
[cancelButton addTarget:self action:@selector(cancelButtonClicked:) forControlEvents:UIControlEventTouchUpInside];
cancelButton.adjustsImageWhenHighlighted = YES;
cancelButton.tag=33;
[menu addSubview: cancelButton];
UIButton *okButton = [UIButton buttonWithType: UIButtonTypeCustom];
okButton.frame = CGRectMake(170, 30, 124, 43);
[okButton setBackgroundImage:[UIImage imageNamed:@"continue_button.png"] forState: UIControlStateNormal];
[okButton addTarget:self action:@selector(okButtonClicked:) forControlEvents:UIControlEventTouchUpInside];
okButton.adjustsImageWhenHighlighted = YES;
[menu addSubview: okButton];
datePickerView = [[UIDatePicker alloc] init];
CGRect pickerRect = datePickerView.bounds;
pickerRect.origin.y = 75;
datePickerView.frame = pickerRect;
//---Picker view for from date selection
if (btnClicked.tag==51)
{
[titleLabel setText:SELECT_FROM_DATE];
NSDate *now = [Global todayDate];
int daysToAdd = 1;
NSDate *newDate = [now dateByAddingTimeInterval:60*60*24*daysToAdd];
// NSLog(@"%@",strDtFromDate);
datePickerView.minimumDate = newDate;
if (holidayType==2)
{
NSDate *holidayFromDate=[dateFormat dateFromString:objectSelectedGroup.fromDate];
// newDate=[holidayFromDate dateByAddingTimeInterval:60*60*24*daysToAdd];
if ([[Global todayDate] compare:holidayFromDate] == NSOrderedAscending)
{
datePickerView.minimumDate = holidayFromDate;
}
else if([[Global todayDate] compare:holidayFromDate] == NSOrderedDescending)
{
datePickerView.minimumDate = newDate;
}
NSDate *holidayToDate=[dateFormat dateFromString:objectSelectedGroup.toDate];
NSLog(@"%@",objectSelectedGroup.fromDate);
NSLog(@"%@",objectSelectedGroup.toDate);
datePickerView.maximumDate = holidayToDate;
}
okButton.tag=34;
}
else if(btnClicked.tag==52)
{
[titleLabel setText:SELECT_TO_DATE];
datePickerView.minimumDate=stringDate;
NSDate *holidayToDate=[dateFormat dateFromString:objectSelectedGroup.toDate];
datePickerView.maximumDate=holidayToDate;
okButton.tag=35;
}
datePickerView.datePickerMode = UIDatePickerModeDate;
stringDate=[datePickerView date];
[datePickerView addTarget:self action:@selector(selectedDateChanged:) forControlEvents:UIControlEventValueChanged];
[menu addSubview:datePickerView];
//menu.actionSheetStyle=UIActionSheetStyleBlackTranslucent;
[menu showInView:self.view];
[menu setFrame:CGRectMake(0,self.view.frame.size.height - 290,320,290)];
同样的代码适用于iphone。 怎么解决这个问题?

UIActionaSheet不适合IPad,他们大部分时间都在帧周围表现不可预测 我建议使用带有自定义UIViewController的UIPopoverController来实现这种用户体验。

您可以尝试使用以下行替换最后两行
[menu setFrame:CGRectMake(0,self.view.frame.size.height - 290,320,290)];
[menu showInView:[[[UIApplication sharedApplication] delegate] window]];

使用PopOver控制器在ipad上显示操作表。要在Popover控制器上使用操作表,请参阅以下链接
