问题 How to get/set the hours and minutes via code from a UIDatePicker in UIDatePickerModeCountDownTimer mode? The situation: I have an interface in that a user selects just hours and minutes. Then, he saves the information (so, I have to get the hours and minutes from UIDatePicker via code to save in a DB).

问题 I have a UIScrollView with 2 pages, and I can scroll horizontally between them. However, on one of my pages, I have a UIDatePicker, and the scroll view is intercepting the vertical touch events so I can no longer manipulate the date picker (except by clicking or tapping). Is there some way to tell the ScrollView to send the vertical touch events to the date picker, but send the horizontal touch events to the scroll view to switch pages? 回答1: I think there's two parts to this problem.

问题 Is it possible to get the day of the week from the onSelect event of the datepicker. I know I can get the day of the month, but I want the day of the week. Even just the day index will be fine e.g. 0-6. I know you can get it in the beforeShowDay (or similar) event, but I need to react differently depending on the day of the week chosen. It's to do with setting the opening times. I could hit the server and find out, but that is not going to come back fast enough...ideally i want it all done on

问题 My app is suddenly unable to correctly display UIDatePickers. I'm using storyboards. The Datepickers are set to just display the date. They are cutting off the month, and also not even showing the days. There's a big space in the middle. I have tried cleaning the project, resetting the simulator, checking localization settings, and checking to see if dynamic type size was set. I'm using Xcode 5.1.1 but the same thing happens in the beta of Xcode 6. Any suggestions would be appreciated. 回答1:

问题 I'm trying to have a UIDatePicker to present only the date, month and year to the user. I want to avoid presenting them with the hours, minutes and seconds like it comes by default. I've tried looking for something that might help but can only find solutions that aren't explained clearly in Objective-C, however I'm coding in Swift. Any ideas?
