问题 I added UIDatePicker in my storyboard, and set mode to CountDownTimer. It shows hours and minutes only, but what i need is minutes and seconds mode. I don't need hour column, need minute and seconds columns. I try to change interval, but it's minimum value is 1 minute. Is it possible? How can I do this? 回答1: You can create a datasource for you minute-seconds picker. It has two Components: minute and seconds. You have to implement some methods in UIPickerViewDelegate and UIPickerViewDataSource

由 我是研究僧i 提交于 2019-12-09 12:02:15

Loading a UIDatePicker in Landscape on a UINavigationController

由 ⅰ亾dé卋堺 提交于 2019-12-09 09:46:28
问题 I have a custom UINavigationController that supports auto-rotate. I also have a UIDatePicker on one of my views that I throw onto the stack of the Navigation controller. The auto-rotate works if I start the date picker view in portrait and then rotate it. If I try load the date picker view in landscape to begin with, the view is all messed up. It looks like it would if it didn't support rotation and the frame only has about half of the picker visible and off center. I've tried making my own

Detect if UIDatePicker is rolling?

由 江枫思渺然 提交于 2019-12-08 16:24:06
问题 I'm using a UIDatePicker in a modal view, to select a date. I found that if the view is closed while the date picker is still rolling, I got a EXC_BAD_ACCESS. How can I detect of the date picker is rolling when the user tab a button? I had two ideas: 1) detect if the value has changed with this: [myDatePicker addTarget:self action:@selector(valueChanged:) forControlEvents:UIControlEventValueChanged]; But I would need to be able to detect if the value WILL change. 2) check if the date is valid

jQuery UI Datepicker and Timezones

由 允我心安 提交于 2019-12-08 13:52:39
I use the datepicker to gererate a requested delivery date on my site. Same day delivery is available until 3pm GMT, so I run a script to move the calendars current selection on by 1 day at that time. The 3pm is generated on the server and not the client machine to ensure the correct time. I would like to overcome this problem: Australian customers moves forward by 1 day as the date there changes naturally (they are 11 hours ahead), this means they miss out on approx 3 hours of same day delivery - but I can live with that. However, when my script kicks in at 3pm UK time they get nudged on
