操作表内的 UIDatePicker 不工作

Question

我试图在操作中显示 UIDatePicker sheet 但它不起作用。

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。虽然运行在模拟器中它工作正常但在设备中工作我无法单击“确定”按钮（uialertaction）...在尝试单击“确定”按钮时选择器不断滚动

Answer 1

由于 UIActionSheet 在 iOS 8.3 中已弃用，您需要按照 Apple 提供的文档和指南在屏幕中添加 DatePicker。

Apple 引入了内联日期选择器（如日历应用程序日期选择器）。

使用下面的 github 内联日期选择器代码

终于找到解决办法了。此代码在设备中运行良好...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];
