Datepicker和警報單中的問題

Question

我正在實施UIDATEPICKER。問題是，當我點擊按鈕，警報片出現，日期選擇器被添加爲子視圖，但我想要兩個按鈕，

1 - 取消2-做

我該怎麼辦？

UIActionSheet * aac = [[UIActionSheet alloc] initWithTitle：@「多少？」 代表：self cancelButtonTitle：nil destructiveButtonTitle：nil otherButtonTitles：nil];

aac.actionSheetStyle = UIActionSheetStyleBlackOpaque; 

sheet = aac; 
UIDatePicker *theDatePicker = [[UIDatePicker alloc] initWithFrame:CGRectMake(0.0, 44.0, 0.0, 0.0)]; 
if(IsDateSelected==YES) 
{ 
    theDatePicker.datePickerMode = UIDatePickerModeDate; 
    theDatePicker.maximumDate=[NSDate date]; 
}else { 
    theDatePicker.datePickerMode = UIDatePickerModeTime; 
} 

self.dtpicker = theDatePicker; 
[theDatePicker release]; 
[dtpicker addTarget:self action:@selector(dateChanged) forControlEvents:UIControlEventValueChanged]; 

pickerDateToolbar = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 0, 320, 44)]; 
pickerDateToolbar.barStyle = UIBarStyleBlackOpaque; 
[pickerDateToolbar sizeToFit]; 

NSMutableArray *barItems = [[NSMutableArray alloc] init]; 

UIBarButtonItem *flexSpace = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFixedSpace target:self action:nil]; 
[barItems addObject:flexSpace]; 

UIBarButtonItem *cancelBtn = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemCancel target:self action:@selector(DatePickerCancelClick)]; 
[barItems addObject:cancelBtn]; 

//// 它亙古不變的..我想這項工作....

我會做什麼？

-(IBAction)DatePickerView 
{ 
    iRolegameAppDelegate *appDelegate = (iRolegameAppDelegate *)[[UIApplication sharedApplication]delegate]; 

pickerViewDate = [[UIActionSheet alloc] initWithTitle:@"How many?" 
               delegate:self 
             cancelButtonTitle:nil 
            destructiveButtonTitle:nil 
             otherButtonTitles:nil]; 

    theDatePicker = [[UIDatePicker alloc] initWithFrame:CGRectMake(0.0, 44.0, 0.0, 0.0)]; 
    theDatePicker.datePickerMode = UIDatePickerModeDateAndTime; 

    NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init]; 
    [dateFormatter setFormatterBehavior:NSDateFormatterBehavior10_4]; 
    [dateFormatter setLocale:[[[NSLocale alloc] initWithLocaleIdentifier:@"en_US"]autorelease]]; 
    [dateFormatter setDateFormat:@"MM/dd/YY h:mm a"]; 
    [theDatePicker addTarget:self action:@selector(dateChanged) forControlEvents:UIControlEventValueChanged]; 


    pickerToolbar = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 0, 320, 44)]; 
    pickerToolbar.barStyle=UIBarStyleBlackOpaque; 
    [pickerToolbar sizeToFit]; 



    NSMutableArray *barItems = [[NSMutableArray alloc] init]; 
    UIBarButtonItem *flexSpace = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemDone target:self action:@selector(DatePickerDoneClick)]; 
    [barItems addObject:flexSpace]; 


    UIBarButtonItem *spacer = [[UIBarButtonItem alloc] 
           initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace 
           target:nil 
           action:nil]; 
    [barItems addObject:spacer]; 




    UIBarButtonItem *cancelBtn = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemCancel target:self action:@selector(DatePickerCancelClick)]; 
    [barItems addObject:cancelBtn]; 


    [pickerToolbar setItems:barItems animated:YES];  
    [pickerViewDate addSubview:pickerToolbar]; 
    [pickerViewDate addSubview:theDatePicker];

    NSDateFormatter *currentdateformate = [[NSDateFormatter alloc] init]; 
    [currentdateformate setDateFormat:@"HH:MM, EEEE, dd-MMMM-yyyy"];

    NSDateFormatter *currentdateformate1 = [[NSDateFormatter alloc] init]; 
    [currentdateformate1 setDateFormat:@"MMM dd, yyyy HH:mm"]; 
    self.updatedate = [currentdateformate1 stringFromDate:[theDatePicker date]]; 
} 

-(IBAction)dateChanged{

    appDelegate.timestamp1 = [currentdateformate stringFromDate:[theDatePicker date]]; 
    NSLog(@"%@",appDelegate.timestamp1); 
    [currentdateformate setDateFormat:@"MMM dd, yyyy HH:mm"]; 
    self.updatedate = [currentdateformate stringFromDate:[theDatePicker date]]; 

} 
-(void)DatePickerCancelClick 
{ 
    self.pickerViewDate.hidden = YES; 
    self.view.hidden = NO; 
    [self.pickerViewDate dismissWithClickedButtonIndex:0 animated:YES]; 

} 

-(BOOL)closeDatePicker:(id)sender{ 
    //iRolegameAppDelegate *appDelegate = (iRolegameAppDelegate *)[[UIApplication sharedApplication]delegate]; 

    [pickerViewDate dismissWithClickedButtonIndex:0 animated:YES]; 
    [pickerToolbar release]; 
    [pickerViewDate release]; 
    //[SelectedTextField resignFirstResponder]; 

    if([ self.updatedate isEqualToString:@"nil"]){ 
     NSDateFormatter *currentdateformate = [[NSDateFormatter alloc] init]; 
     [currentdateformate setDateFormat:@"MMM dd, yyyy HH:mm"]; 
     self.updatedate = [currentdateformate stringFromDate:[theDatePicker date]]; 
     [dateSelectButton setTitle:self.updatedate forState:UIControlStateNormal]; 
     self.updatedate = @""; 
    } 
    else{ 
     [dateSelectButton setTitle:self.updatedate forState:UIControlStateNormal]; 
     self.updatedate = @""; 
    } 

    return YES; 
} 

-(IBAction)DatePickerDoneClick{ 
    [self closeDatePicker:self]; 


}

也許你應該擺脫UIActionSheet，並像我做另一個問題那樣做。

UIDatePicker pop up after UIButton is pressed
