uidatepicker

问题 I have a UIDatepicker created in UIBuilder and instantiated once when the app first loads. When first presented, the datepicker correctly flags today's date with the word 'Today'. On IOS 4, if I dismiss the app to the background, and reactivate it a day later, the date has advanced, but yesterdays date is still flagged as 'Today'. Explicitly updating the controls date has no effect. It looks like the control determines 'Today' only once, when created. I've tried calling init to re-initialise

问题 I have a pop menu that contains a form with a jquery datepicker and the issue is that when I make a date selection, both the menu and the datepicker calendar closes. I tried to use event.stopPropagation() in the Select event for the datepicker, but the I couldn't find a way to get a handle for the "event". Also, I tried to return false at the end of the select event but again with no luck. Any help will be much appreciated. Thanks. 回答1: I was facing same issue and fixed it by adding in

问题 I'm using the JQuery UI Datepicker to pick date. I set "changeMonth" and "changeYear" to true at the initialization. $( "#from" ).datepicker({ defaultDate: "+1w", changeMonth: true, changeYear: true, dateFormat: 'yy-mm-dd', onClose: function( selectedDate ) { $( "#to" ).datepicker( "option", "minDate", selectedDate ); } }); $( "#to" ).datepicker({ defaultDate: "+1w", changeMonth: true, changeYear: true, dateFormat: 'yy-mm-dd', onClose: function( selectedDate ) { $( "#from" ).datepicker(

问题 I'm using jQuery UI Datepicker to make a two field submission form. I want the user to create a range and submit it to see results. However, they obviously cannot pick a start date that happens more recently than an end date (you can't see a range starting today and going to yesterday). As of now, I've been able to put an alert on selection of the second one if the first one happened before it, but I can't figure out how to have the datepicker stay open so the user can select something else.

问题 Is there a way to show hebrew month names in a UIDatePicker instead of Gregorian ones? How? Can this be set programmatically? 回答1: There is a bug in UIDatePicker that prevents it from correctly honoring the calendar property (which is how you're supposed to do this). Please file a bug report and it will be fixed. 回答2: If you are using IB to create your view you can add a UIDatePicker and set its Locale property to "Hebrew". 回答3: I don't think that is possible, however you can create your own

问题 I'm having a few strange issues with the UIDatePicker. I checked the forums and I haven't had any luck with the answers supplied. Say I pick a date, 20/11/2010 EN_AUS locale. When I NSLog it the date property is 2010-11-19 13:00:00 +0000. But when I format it and display in a label it appears correct, i.e. 20/11/2010?! I save this date so that the next time the user enters this view the uiDatePicker should automatically be set at the last selected date. But it just isn't happening, it still

问题 I have a UIDatePicker using UIDatePickerModeTime that I use in an iPhone app modally, works fine: Using this same basic code for iPad, but putting the view in a UIPopoverController gives some pretty inconsistent results.

Notice how 2 of them are not rendering at all, but instead have no content UIDatePickerModeTime UIDatePickerModeCountDownTimer UIDatePickerModeDateAndTime UIDatePickerModeDate What could be

问题 Is it possible to modify the tint color of a UIDatePicker 's selection indicator? Or can it be removed so I can add my own selection indicator image? I know in the case of UIPickerView ´s you can disable the selection indicator so that you can provide your own selection indicator image. 回答1: There is no option to change the color of selection indicator by default. You can make a workaround though. I would add a simple UIView with a color of your choice and alpha value for transparency. Se the

问题 I have a UIDatePicker that well, allows you to select a date (not time). I then save this NSDate and use display it in a label on a different view.
