Question

我正在努力使我的应用内容可以在Core Spotlight的帮助下进行搜索。一切都很好，标题和描述都没有缩略图。

这是我正在尝试的：

CSSearchableItemAttributeSet *attributeSet = [[CSSearchableItemAttributeSet alloc]initWithItemContentType:(NSString *)kUTTypeImage];

attributeSet.title = @"My First Spotlight Search";
attributeSet.contentDescription = @"This is my first spotlight Search";

attributeSet.keywords = [NSArray arrayWithObjects:@"Hello", @"Welcome",@"Spotlight", nil];

UIImage *image = [UIImage imageNamed:@"searchIcon.png"];
NSData *imageData = [NSData dataWithData:UIImagePNGRepresentation(image)];
attributeSet.thumbnailData = imageData;

CSSearchableItem *item = [[CSSearchableItem alloc]initWithUniqueIdentifier:@"com.deeplink" domainIdentifier:@"spotlight.sample" attributeSet:attributeSet];

[[CSSearchableIndex defaultSearchableIndex] indexSearchableItems:@[item] completionHandler: ^(NSError * __nullable error) {
    if (!error)
        NSLog(@"Search item indexed");
}];

iOS 9 beta 1发行说明指出缩略图尚未用于搜索结果。请参阅：https://developer.apple.com/library/prerelease/ios/releasenotes/General/RN-iOSSDK-9.0/index.html

CoreSpotlight缩略图图像未显示在Spotlight搜索上
