i want to use showActionSheet to display the different pickerview when click diffrent tableViewCell
but i got two problem:
the checkInDate and theCheckOutDate can not be show the second time if i use checkOutDate.date = nowDate;
how can i use multi pickerview in this view? it should not be multiple Components.
here is the main code:
- (void)viewDidLoad {
age = [[UIPickerView alloc] init];
age.showsSelectionIndicator = YES;
age.delegate = self;
NSArray *ageData = [[NSArray alloc] initWithObjects:#"1", #"2", #"3", nil];
self.pickerData = data;
//room = [[UIPickerView alloc] init];
//room.showsSelectionIndicator = YES;
//room.delegate = self;
//NSArray *roomData = [[NSArray alloc] initWithObjects:#"6", #"7", nil];
//self.pickerData = roomDate;
//check data
NSCalendar *gregorian = [[NSCalendar alloc] initWithCalendarIdentifier:NSGregorianCalendar];
NSDateComponents *components = [[NSDateComponents alloc] init];
components.day = 1;
NSDate *now = [NSDate date];
NSDate *nextDay = [gregorian dateByAddingComponents:components toDate:now options:0];
NSDateFormatter *formatter = [[[NSDateFormatter alloc] init] autorelease];
formatter.dateFormat = #"yyyy-MM-dd";
checkInDateStr = [formatter stringFromDate:nextDay];
NSDate *dayAfterTom = [gregorian dateByAddingComponents:components toDate:nextDay options:0];
checkOutDateStr = [formatter stringFromDate:dayAfterTom];
checkInDate = [[UIDatePicker alloc] init];
checkInDate.tag = checkInDateTag;
[checkInDate setMinimumDate:now];
checkInDate.datePickerMode = UIDatePickerModeDate;
//checkInDate.date = nextDay;
checkOutDate = [[UIDatePicker alloc] init];
checkOutDate.tag = checkOutDateTag;
[checkOutDate setMinimumDate:nextDay];
checkOutDate.datePickerMode = UIDatePickerModeDate;
//checkOutDate.date = dayAfterTom;
}
- (void)showActionSheet:(NSIndexPath *)indexPath withDataPickerTag:(NSInteger *)tag{
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:title delegate:self cancelButtonTitle:#"cancel" destructiveButtonTitle:nil otherButtonTitles:#"done", nil];
[actionSheet showInView:self.view];
//UIDatePicker *datePicker = [[[UIDatePicker alloc] init] autorelease];
// datePicker.tag = 101;
// datePicker.datePickerMode = UIDatePickerModeDate;
// NSDate *now = [NSDate date];
// [datePicker setDate:now animated:YES];
if (tag == 201){
[actionSheet addSubview:checkInDate];
}else if (tag == 202){
[actionSheet addSubview:checkOutDate];
}
}

Answer 1

You can set the frame of a picker view.
Instead of
age = [[UIPickerView alloc] init];
Use
UIPickerView *picker = [[UIPickerView alloc] initWithFrame:<Your frame>];
or
[picker setFrame:<your frame>];
Using this you can use multiple picker views.
Keep an identifier to both so that you can handle the delegates.
