大家好我正在使用名为spotlight功能的新iOS 9功能。我无法获得我在聚光灯搜索中写的文字，当我们从聚光灯搜索回到我的应用程序时我正在使用corespotlight框架
- (void)setUpCoreSpotLightSearch {
self.userActivity = [[NSUserActivity alloc]
initWithActivityType:@"com.pulpstrategy.spotlight"];
self.userActivity.title = @"Test";
self.userActivity.userInfo = @{@"subjectid" : @"5" , @"subjecttype" : @"type"};
NSLog(@"userInfo %@", self.userActivity.userInfo);
self.userActivity.eligibleForSearch = YES;
self.userActivity.eligibleForPublicIndexing = YES;
self.userActivity.webpageURL = [NSURL URLWithString:@"http://www.google.com"];
CSSearchableItemAttributeSet *attributeSet = [[CSSearchableItemAttributeSet alloc]initWithItemContentType:(NSString *)kUTTypeImage];
attributeSet.title = @"My";
attributeSet.contentDescription = @"";
attributeSet.keywords = [NSArray arrayWithObjects:@"Hello",@"Welcome",@"Utkarsh", nil];
UIImage *img = [UIImage imageNamed:@"A.jpeg"];
NSData *imgData = [NSData dataWithData:UIImagePNGRepresentation(img)];
attributeSet.thumbnailData = imgData;
CSSearchableItem *item = [[CSSearchableItem alloc]initWithUniqueIdentifier:@"com.pulpstrategy.spotlight" domainIdentifier:@"spotlight.CoreSpotLight" attributeSet:attributeSet];
[[CSSearchableIndex defaultSearchableIndex]indexSearchableItems:[NSArray arrayWithObject:item] completionHandler:^(NSError * _Nullable error) {
if (!error) {
NSLog(@"Item = %@",error.localizedDescription);
}
}];
}
在搜索之后我正在使用：
- (BOOL)application:(UIApplication *)application continueUserActivity:(NSUserActivity *)userActivity restorationHandler:(void(^)(NSArray *restorableObjects))restorationHandler {
userActivity.eligibleForSearch = YES;
NSLog(@"Handler = %@",restorationHandler);
if ([[userActivity activityType] isEqualToString:CSSearchableItemActionType]) {
// This activity represents an item indexed using Core Spotlight, so restore the context related to the unique identifier.
// The unique identifier of the Core Spotlight item is set in the activity’s userInfo for the key CSSearchableItemActivityIdentifier.
NSString *uniqueIdentifier = [userActivity.userInfo objectForKey:CSSearchableItemActivityIdentifier];
NSString *valueForUID = [self.userActivity valueForKey:uniqueIdentifier];// The app is crashed that line piece of code.
ViewController *viewController = [[ViewController alloc] initWithNibName:@"ViewController" bundle:nil];
NSLog(@"value for UID = %@",valueForUID);
[navController pushViewController:viewController animated:YES];
}
return YES;
}
