点击UISearchController（搜索栏）时显示日期选择器

Question

我正在以编程方式使用UISearchController，在点按Searchbar textField时，我希望将日期选择器设置为inputView

@property (strong, nonatomic) UISearchController *searchController;

文字字段的引用：iPhone display date picker on UITextField touch
但无法访问搜索栏Textfield。请帮忙。

Answer 1

您可以使用以下代码获取搜索textField。将其写在viewDidLoad

中

UITextField *searchBarTextField = [self.searchController.searchBar valueForKey:@"_searchField"];
[searchBarTextField setInputView:datePicker];

希望这会对你有所帮助

Answer 2

首先设置UISearchBar的委托，然后您可以使用以下委托方法：

- (BOOL)searchBarShouldBeginEditing:(UISearchBar*)searchBar {
    [self showDatePicker];
    return NO;
}

-(void) showDatePicker {
    UIDatePicker *datePicker = [[UIDatePicker alloc]init];
    datePicker.datePickerMode = UIDatePickerModeDate;
    [datePicker setDate:[NSDate date]];
    [datePicker addTarget:self action:@selector(showSelectedDate:) forControlEvents:UIControlEventValueChanged];
}

- (void)showSelectedDate:(id)sender {
    UIDatePicker *picker = (UIDatePicker*)self.date.inputView;
    searchBar.text = [self formatDate:picker.date];
}

您可以使用任何日期格式化程序以所需格式显示日期。
