uidatepicker

问题 This question already has an answer here : Closed 6 years ago . Possible Duplicate: How to customize the UIDatePicker I need to customize UIDatePicker as we do support a variety of date formats like dd-MM-yyyy , dd-MM-yyyy HH:mm:ss , dd-MM .

问题 I know that this question as been made other times, but with xCode 7 and iOS9.2 is it possible to change the font color of "today" date on a UIDatePicker? [self.dpData setValue:[UIColor colorWithRed:111/255.0f green:113/255.0f blue:121/255.0f alpha:1.0f] forKeyPath:@"setHighlightsToday"]; I tried this and it crashed, so I know that this don't work. Any other options that I have, or I really need to build my own DatePicker? Thanks in advance. 回答1: A safer/easier way to do it is to simply set

问题 The UIDatePicker with it's mode set on "Timer", only has values from 0 to 23 hours. I'd like to have more hours (like, up to 48 hours). It also shows a nice "floating" text next to the number on the selected row. I can actually "imitate" the "floating" hours effect, by adding a label on top of the UIPickerView, but I'd lose the second column with the minutes interval, and I'd really like to have 30 minute interval on a pickerView. But I really need more values on the hours column. Any

问题 I have a UIDatePicker that works properly however I want to modify the date and time to look like the following: 04-23-2013 11:10 instead of 2013-04-23 16:12:10. How would I go about this? Here is my code. .h @interface SchedulerViewController : UIViewController <UITableViewDelegate,UITableViewDataSource> { IBOutlet UITableView *tableview; IBOutlet UIDatePicker *datePicker; IBOutlet UITextField *eventText; } @property (nonatomic, retain) IBOutlet UITableView *tableview; @property (nonatomic,

问题 I've got an iPhone app that I've made, that on one view has a UIDatePicker. When you initially launch the app - and the view first loads; inside the viewDidLoad I have the UIDatePicker get set to the current date/time. It works fine. Now if the user minimizes the app and does other things (but does not kill the app) and then goes back to the app, the date/time does not update when you go back to that view. I'm wondering how I would go about making it 'refresh' that UIDatePicker any time the

问题 EDIT: For future reference: found this for NSDateFormatter. This documentation shows the different code to display the proper date and time format you are looking for. Cheers. http://www.alexcurylo.com/blog/2009/01/29/nsdateformatter-formatting/ I am creating an app that uses a UIDatePicker to select a date AND time for an event (there is an option for this in the storyboard). I want to know how I can display both the date AND the time in a label after selection/save. Right now, this is what

问题 I have simplified my work for this question but the same problem remains. I am using the Textbox HTML helper to display empty textboxes as I loop through the items in this model. <% foreach (var item in Model) { %> <tr> <td><%: item.ID %></td> <td><%: Html.TextBox("usernames", null, new { @class = "datepicker" }) %></td> <td><%: item.Password %></td> <td> <%: item.Race %></td> </tr> <% } %> Because I have several rows this produces several fields all with the class "datepicker". I am applying

问题 I was using regular datePicker from grails but I decided it was easier to use a textField with a calendar next to it and I was recommended to use Grails-UI. My problem is that now, when I click to apply the filters, they do not work. Somehow they are not being recognized. Any help would be greatly appreciated. Here is the code for the controller: def searchResults = { def fromCal if(params?.lastUpdatedD) { fromCal = Calendar.getInstance() fromCal.setTime(params?.lastUpdatedD) fromCal.set

问题 I'm setting a datepicker on a textfield.

问题 How is this possible to select a two-digit year in ui-datepicker? When I try to select 24 year or 79 year It returns 1924 or 1979. How can I select the two-digit correctly?
