我正在尝试在文本字段中的datePicker中显示时间。我已经走到了这一步
UITextField *textField = [[UITextField alloc] initWithFrame:CGRectMake(112, 88, 97, 30)];
textField.borderStyle = UITextBorderStyleRoundedRect;
textField.contentVerticalAlignment = UIControlContentVerticalAlignmentCenter;
[self.view addSubview:textField];
UIDatePicker *datePicker = [[UIDatePicker alloc] init];
datePicker.datePickerMode = UIDatePickerModeDate;
[datePicker addTarget:self action:@selector(datePickerValueChanged:) forControlEvents:UIControlEventValueChanged];
datePicker.timeZone = [NSTimeZone defaultTimeZone];
datePicker.minuteInterval = 5;
datePicker.datePickerMode = UIDatePickerModeTime;
[textField setInputView:datePicker];
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateStyle: NSDateFormatterShortStyle];
textField.text = [dateFormatter stringFromDate:datePicker.date];
但是文本字段不会改变
答案 0 :(得分:3)
您的-(void)datePickerValueChanged:
方法是什么样的?
看起来如下:
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateStyle: NSDateFormatterShortStyle];
textField.text = [dateFormatter stringFromDate:datePicker.date];
其中textField
是正在编辑的textField,而datePicker
是其值已更改的日期选择器?
