UIDatePicker的AM / PM设置错误

Question

我将UIDatePicker设为时间选择器，并将时间设置为15:00。在某些地区，例如美国，它将在车轮中正确显示为03:00，而不是＆＃34; PM＆＃34;，它显示＆＃34; AM＆＃34;。有关如何正确设置的任何想法？

当前代码：

    NSCalendar *gregorian = [[NSCalendar alloc] initWithCalendarIdentifier:NSGregorianCalendar];
    NSDateComponents *comps = [gregorian components:(NSHourCalendarUnit | NSMinuteCalendarUnit) fromDate:_dateWithTime];
    comps.hour = 15;
    comps.minute = 0;

    UIDatePicker *datePicker = [[UIDatePicker alloc] init];
    datePicker.datePickerMode = UIDatePickerModeTime;
    datePicker.minuteInterval = 15;
    datePicker.timeZone = [NSTimeZone localTimeZone];
    datePicker.minimumDate = [gregorian dateFromComponents:comps];
    [datePicker addTarget:self action:@selector(checkinDatePickerChanged:) forControlEvents:UIControlEventValueChanged];

Answer 1

我不确定这是否可以解决您的问题，而不是

datePicker.minimumDate = [gregorian dateFromComponents:comps];

应该有

datePicker.date = [gregorian dateFromComponents:comps];
