uidatepicker

问题 i want to use jquery UI's datepicker to trigger a POST that would then load information from the date picked on the datepicker from my database. so i guess this is a two-part question is there a way i can make it so the datepicker date, when selected, just gets passed into a POST, so someone would click on jan 1 2010 and it would automatically go to mysite.com?date=01012010 or something like that the way it is now the datepicker just updates a text box with the date, so upon clicking on jan 1

问题 Is there is a public interface to set the font for a UIDatePicker in Swift 3? I am well aware that similar questions have been asked, mainly asking about how to change the color of labels inside a UIDatePicker. Using something like datePicker.setValue(UIColor.someColor, forKey: "textColor") is accessing a private property, which could raise some eyebrows. And using appearanceWhenContainedIn doesn't expose neither the label's textColor nor its font: UILabel.appearance

问题 Just barely getting into iOS development using swift and getting a little overwhelmed sometimes trying to look at documentation and understand it. I am also currently running through Simon Allardice's iOS app development with swift essential training on Lynda.com and had a question regarding one of the objects we have instantiated in the WhatDay example. We basically are setting up a UIDatePicker object from which we are extracting what day of the week we are looking at with the

问题 I’m using a UIDatePicker to update UILabel with a date, but I’m noticing that the valueChanged event is only called when the wheels stop spinning. Ideally if the user flicks a column, I’d like the date in the label to update continuously as the wheel spins, for a realtime sense of feedback. Is this possible? 回答1: This is an extreme workaround, but... If you use a UIPickerView instead of a UIDatePicker (which, granted, would entail re-implementing most of the DatePicker), you can detect the

问题 I have an app where I ask for the users birthday with a UIDatePicker then store it in standard user defaults. When the app is opened again I get the date again and then want to set the UIDatePicker to that date but it's crashing and not accepting the date. It's being stored in the format "June 8, 2009." How do I need to do this? This is the way I'm trying it now: - (void)viewWillAppear:(BOOL)animated { birthDate = [Preferences getBirthDate]; if (birthDate == nil) { [datePicker setDate:[NSDate

问题 I'm sorry to make my first question here a bit of a simple one -- I've spent a day reading the NSLocale and NSCalendar class descriptions but I couldn't see if this was possible. I have a UIDatePicker in the UIDatePickerModeDateAndTime mode. It is currently displaying date and time according to the user's locale, which is the default behavior. I would like to be able to offer the option to show the UIDatePicker in either 12-hour or 24-hour time format. Detecting which time format the user is

问题 Seeing from this url, date picker is shown as month-date-year , can i change it to date-month-year ? 回答1: This is determined by the locale setting of the device it's running on, as per the Developer Page (look at the DatePicker mode sections). The exact items shown and their order depend upon the locale set. The property 'locale' can be used to explicitly specify a mode to use, but this is deprecated as of iOS 5. It's generally best to leave this setting alone, so that the date will display

问题 Basically this issue started when I updated my app to run with iOS 9. Without making any change in the code now a white square appears over the picker view, but it works normally. Note that the user can hide and show the picker views and the cells they're in. If you need more info leave a comment. UPDATE : Here is the full screenshot of the Table View: UPDATE 2 : The following shows when I preview (press bar space button) the _pickerView property in the variables debugger. This makes me think
