iphone - 关闭 UIDatePicker

Question

我将 UIDatePicker 添加为 UITextField 的输入 View

UIDatePicker    *oBirth;
NSDateFormatter *dateFormat;

_editingField = [[UITextField alloc] initWithFrame : CGRectMake(80, 12, 215, 25)];    
dateFormat = [[NSDateFormatter alloc] init];
[dateFormat setDateFormat : @"dd/MM/yyyy"];

oBirth = [[UIDatePicker alloc] initWithFrame : CGRectMake(0, 0, 120, 45)];
oBirth.date = [dateFormat dateFromString : sField];
NSLog(@"%@", oBirth.subviews);
[oBirth addTarget : self
           action : @selector(updateDate:)
 forControlEvents : UIControlEventValueChanged];
[oBirth addTarget : self
           action : @selector(dismissDate:)
 forControlEvents : UIControlEventTouchUpOutside];
[oBirth setDatePickerMode : UIDatePickerModeDate];
_editingField.tag = 1;
_editingField.inputView = oBirth;

如何在不创建不可见 View 的情况下关闭 UIDatePicker ？

Answer 1

试试这个

[_editingField resignFirstResponder];

编辑

对于 dismissDate 没有被调用。
删除这段代码

[oBirth addTarget : self
           action : @selector(dismissDate:)
 forControlEvents : UIControlEventTouchUpOutside];

并添加这个

     // single tap gesture recognizer
        UITapGestureRecognizer *tapGestureRecognize = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(dismissDate:)];
        tapGestureRecognize.numberOfTapsRequired = 1;
        [self.view addGestureRecognizer:tapGestureRecognize];

您的回调

- (void)dismissDate:(UIGestureRecognizer *)gestureRecognizer {
    NSLog(@"Resign your responder");
}
