因此，我有一种方法可以将键盘更改为UIDatePicker，并希望用户选择日期以设置提醒。到目前为止，我已经将键盘替换为UIDatePicker，并且当我打印出日期字符串时，无论我设置了什么，它都只会打印当前日期。
self.datePicker = [[UIDatePicker alloc] init];
[self.noteTextView becomeFirstResponder];
[self.noteTextView setInputView:self.datePicker];
NSDate *date = self.datePicker.date;
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateStyle:NSDateFormatterMediumStyle];
[dateFormatter setTimeZone:NSDateFormatterNoStyle];
[dateFormatter setLocale:[NSLocale currentLocale]];
self.myDate = [dateFormatter stringFromDate:date]; //a string of the date that I want to use in other methods
NSLog(@"Date: %@", [dateFormatter stringFromDate:date]);
最佳答案
UIDatePicker的默认日期是当前日期，这就是您要打印的日期。挑选日期使用
[self.myDatePicker addTarget:self action:@selector(datePickerChanged:) forControlEvents:UIControlEventValueChanged];
- (void)datePickerChanged:(UIDatePicker *)datePicker
{
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:@"dd-MM-yyyy HH:mm"];
NSString *strDate = [dateFormatter stringFromDate:datePicker.date];
NSLog(@"Date: %@", strDate);
}
关于ios - UIDatePicker返回当前日期，即使我选择其他日期也是如此，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/28229596/
