UIAlertController触摸无法正常工作

Question

我向UIAlertController添加了选择器视图，但它的触摸不适用于整个选择器，它只是在拾取器的某个特定部分上工作。请帮我解决这个问题

此代码：

if (IS_IOS8_AND_UP) {

    UIAlertController * searchActionSheet=[UIAlertController alertControllerWithTitle:@"" message:@"" preferredStyle:UIAlertControllerStyleActionSheet];

    [searchActionSheet.view setBounds:CGRectMake(8, 180, self.viewSize.width, sheetHeight)];

// aView.frame = CGRectMake（100,100，aView.frame.size.width，aView.frame.size.height）;

  //yourView represent the view that contains UIPickerView and toolbar

[searchActionSheet.view addSubview：aView];         // [[self topViewController] .view addSubview：searchActionSheet.view];         [[self topViewController] presentViewController：searchActionSheet animated：YES completion：nil];

}
else
{
    _actionSheet = [[UIActionSheet alloc] initWithTitle:paddedSheetTitle delegate:nil cancelButtonTitle:nil destructiveButtonTitle:nil otherButtonTitles:nil];
    [_actionSheet setActionSheetStyle:UIActionSheetStyleBlackTranslucent];
    [_actionSheet addSubview:aView];
    [self presentActionSheet:_actionSheet];
    _actionSheet.bounds = CGRectMake(0, 0, self.viewSize.width, sheetHeight);
}

Answer 1

UIAlertController * searchActionSheet=[UIAlertController alertControllerWithTitle:@"" message:@"" preferredStyle:UIAlertControllerStyleActionSheet];
UIAlertAction *alertAction = [UIAlertAction actionWithTitle:@"" style:UIAlertActionStyleDefault handler:nil]; 
[searchActionSheet addAction:alertAction];
[searchActionSheet addAction:alertAction];
[searchActionSheet addAction:alertAction];
[searchActionSheet addSubview:picker];

将alertAction对象添加到alertcontroller，如上所述。之后尝试将您的选择器作为子视图添加到alertcontroller。

根据需要添加尽可能多的alertAction对象以调整视图。不知道这是否正确，但它对我有用。
