UIAlertController觸摸不能正常工作

Question

我向UIAlertController添加了選擇器視圖，但它的觸摸不能在整個選擇器上工作，它只是在選擇器的某個特定部分工作。請大家幫我出這個

代碼如下：

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); 
} 

看到圖像

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]; 

添加alertAction目的是alertcontroller正如我上面添加。之後，嘗試將你的選擇器作爲子視圖添加到alertcontroller。

根據需要添加儘可能多的alertAction對象來調整視圖。不知道這是否是正確的方式，但它對我有用。
