我使用以下代码为UIDatePicker,无论选择它的日期是在标签中显示.但是我需要在选择日期后关闭选择器.这可能请建议我.

我使用以下代码:

- (void)viewDidLoad {
    [super viewDidLoad];

    //Create label
    label = [[UILabel alloc] init]; 
    label.frame = CGRectMake(10, 10, 300, 40);
    label.textAlignment = UITextAlignmentCenter;

    //Use NSDateFormatter to write out the date in a friendly format
    NSDateFormatter *df = [[NSDateFormatter alloc] init];
    df.dateStyle = NSDateFormatterMediumStyle;
    label.text = [NSString stringWithFormat:@"%@",
                  [df stringFromDate:[NSDate date]]];
    [df release];
    [self.view addSubview:label]; 
    [label release];

    // Initialization code
    datePicker = [[UIDatePicker alloc] initWithFrame:CGRectMake(0, 250, 325, 250)];
    datePicker.datePickerMode = UIDatePickerModeDate;
    datePicker.hidden = NO;
    datePicker.date = [NSDate date];
    [datePicker addTarget:self
                   action:@selector(changeDateInLabel:) …
