Question

我正在尝试在操作表中显示UIDatePicker，但它无效。

这是我的代码。点击按钮我写了这段代码

 UIAlertController *alertController = [UIAlertController alertControllerWithTitle:nil message:@"\n\n\n\n\n\n\n\n" preferredStyle:UIAlertControllerStyleActionSheet];

UIView *datePickerView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, 200)];
[datePickerView setBackgroundColor:[UIColor clearColor]];

CGRect pickerFrame = CGRectMake(0, 0, self.view.frame.size.width, 200);
UIDatePicker *datePicker = [[UIDatePicker alloc] initWithFrame:pickerFrame];
[datePicker setDatePickerMode:UIDatePickerModeDate];

[datePickerView addSubview:datePicker];
[alertController.view addSubview:datePicker];

UIAlertAction* alertAction = [UIAlertAction actionWithTitle:@"OK" style:UIAlertActionStyleDefault                                                           handler:^(UIAlertAction * action) {


}];

[alertController addAction:alertAction];

[self.view.window.rootViewController presentViewController:alertController animated:YES completion:nil];

[alertAction setValue:[UIColor redColor] forKey:@"titleTextColor"];

这是更新后的代码。在模拟器中运行它工作正常，但在设备中工作我无法单击确定按钮（uialertaction）...尝试单击确定按钮选择器正在连续滚动

Answer 1

UIActionSheet已弃用iOS 8.3，您需要使用Apple提供的文档和指南在屏幕中添加DatePicker。

Apple推出了使用内联日期选择器（如日历应用日期选择器）。

使用下面的github Code for Inline Date Picker

Answer 2

最后我得到了解决方案。此代码在设备中正常工作...感谢您的帮助

   UIAlertController *alertController = [UIAlertController alertControllerWithTitle:nil message:@"\n\n\n\n\n\n\n\n" preferredStyle:UIAlertControllerStyleActionSheet];

UIDatePicker *datePicker = [[UIDatePicker alloc] init];

CGRect pickerFrame = datePicker.frame;
pickerFrame.size.height = datePicker.frame.size.height - 50;
datePicker.frame = pickerFrame;

[datePicker setDatePickerMode:UIDatePickerModeDate];
[alertController.view addSubview:datePicker];

UIAlertAction* alertAction = [UIAlertAction actionWithTitle:@"OK" style:UIAlertActionStyleDefault                                                           handler:^(UIAlertAction * action) {

}];

[alertController addAction:alertAction];

[self.view.window.rootViewController presentViewController:alertController animated:YES completion:nil];

动作表内的UIDatePicker不起作用
