如何将UIDatePicker中的分钟组件设置为零

Answer 1

如果您的问题是将UIDatePicker设置为仅显示以分钟为单位的00组件，则答案是NO。

您可以更改UIDatePicker的minuteInterval属性->最小值为1，最大值为30。

Answer 2

您需要将所选日期截断为60秒间隔。例如：

long long truncedDate = [datePicker.date timeIntervalSinceReferenceDate];
truncedDate /= 60;
truncedDate *= 60;
datePicker.date = [NSDate dateWithTimeIntervalSinceReferenceDate:truncatedDate];

Answer 3

我只是在我的DatePicker中将分钟组件设置为零，方法如下：

//set current date to datepicker myDatePicker.timeZone = NSTimeZone.local

//create a dateFormatter with "00" instead of "mm" in the minute component: let dateFormatter = DateFormatter() dateFormatter.dateFormat = "yyyy-MM-dd HH:00" let myStringDate = dateFormatter.string(from: myDatePicker.date)

//once we have in String format with minute 00, we convert it to date format to load in DatePicker let myDateDate = dateFormatter.date(from: myStringDate) myDatePicker.setDate(myDateDate!, animated: true)
