Question

我正在创建这样的日期选择器：

UIDatePicker *datePicker = [[UIDatePicker alloc] init];
[datePicker setFrame:self.txtFieldDatePicker.frame];

NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];

[dateFormatter setLocale:[self getCurrentLocale]];

[dateFormatter setDateFormat:@"MM-dd-yyyy"];

NSDate *dateForPicker = [dateFormatter dateFromString:self.txtFieldDatePicker.text];
if (dateForPicker)
{
    [datePicker setDate:dateForPicker];
}
datePicker.datePickerMode = UIDatePickerModeDate;

objc_setAssociatedObject(datePicker,
                         (void*)MyConstKeyForDatePicker,
                         self.txtFieldDatePicker,
                         OBJC_ASSOCIATION_RETAIN);

[datePicker addTarget:self action:@selector(datePickerValueChanged:) forControlEvents:UIControlEventValueChanged];
//                datePicker.tag = txtField.tag+1;
self.txtFieldDatePicker.inputAccessoryView = toolbar;

self.txtFieldDatePicker.inputView = datePicker;

我的getCurrentLocal：

-(NSLocale *)getCurrentLocale
{
NSLocale *enUSPOSIXLocale;
enUSPOSIXLocale = [[NSLocale alloc] initWithLocaleIdentifier:@"en_US_POSIX"];
return enUSPOSIXLocale;
}

我期待UIDatePicker始终在MM-dd-yyyy中显示日期。

有趣：当我进入iPad设置＆gt;一般＆gt;并将区域更改为美国，我的代码完美无缺，UIDatePicker始终在MM-dd-yyyy中显示。如果我将区域更改为任何其他内容（印度），UIdate Picker会以dd-MM-yyyy显示日期为何？

我总是希望在MM-dd-yyyy中展示。

试试这个

 NSLocale *indain = [[NSLocale alloc] initWithLocaleIdentifier:@"en_IN"];
    NSCalendar *cal = [NSCalendar currentCalendar];
    [cal setLocale:indain];
    [datePicker setCalendar:cal];
    datePicker.datePickerMode = UIDatePickerModeDate;
    datePicker.date = [NSDate date];

更改区域中的UIDatePicker格式问题
