iOS 9 CoreSpotlight API Xamarin Crash on Index()
У меня есть следующие строки кода:
var attributes = new CSSearchableItemAttributeSet ();
attributes.Title = "Title";
attributes.ContentDescription = "Description";
var item = new CSSearchableItem ("1", "space", attributes);
if (CSSearchableIndex.IsIndexingAvailable) {
CSSearchableIndex.DefaultSearchableIndex.Index (new [] { item }, (error) => {
if (error != null) {
Console.WriteLine("success");
} else {
Console.WriteLine("fail");
}
});
}
которые дают мне этот вид краха и "успех" ветка никогда не достигается:

Хотя, если я изменю строку Index(), чтобы вообще не добавлять элементы, сбоя не произойдет, и поток выполнения попадет в консоль "fail":
CSSearchableIndex.DefaultSearchableIndex.Index (new CSSearchableItem[] { }, (error) => {
Я также попытался установить различные свойства на CSSearchableItemAttributeSet объект, не повезло.
Есть идеи, как летать на нем?

Решение
Используется неправильный инициализатор. Вместо того, чтобы называть равнину
var attributes = new CSSearchableItemAttributeSet ();
Я должен был указать itemContentType
var attributes = new CSSearchableItemAttributeSet (itemContentType: "");
