【IOS工具类】IOS9的CoreSpotlight(OC语言)

什么是CoreSpotlight？就是在IOS9下，让用户在下拉的搜索页面里可以搜索到你的应用。

#import <Foundation/Foundation.h>

@interface IOS9SearchAPIUtil : NSObject

+(IOS9SearchAPIUtil *)sharedInstance;

-(void)addSearchItemsArray:(NSArray *)array;

@end

#import "IOS9SearchAPIUtil.h"
#import <CoreSpotlight/CoreSpotlight.h>
#import <MobileCoreServices/MobileCoreServices.h>
#import "NSString+Wrapper.h"
#import <UIKit/UIKit.h>

#define IOS9SearchAPIUtil_domainIdentifier @"com.searchapi.shows"
@implementation IOS9SearchAPIUtil

+(IOS9SearchAPIUtil *)sharedInstance{
static IOS9SearchAPIUtil *instance = nil;
static dispatch_once_t predicate;
dispatch_once(&predicate, ^{
instance = [[self alloc] init];
});
return instance;
}

-(void)addSearchItemsArray:(NSArray *)array{
if(IS_IOS_9){
NSMutableArray <CSSearchableItem *> *searchableItems = [NSMutableArray arrayWithCapacity:0];
for (NSDictionary *d in array) {
NSString *title = [d objectForKey:@"title"];
NSString *desc = [d objectForKey:@"desc"];
NSString *time = [d objectForKey:@"time"];
NSString *nid = [d objectForKey:@"nid"];
CSSearchableItemAttributeSet *attributeSet = [[CSSearchableItemAttributeSet alloc]initWithItemContentType:@"SearchAPIViews"];
attributeSet.title = title;
attributeSet.contentDescription = [NSString stringWithFormat:@"%@\n%@",desc,time];
NSMutableArray *keywords = [NSMutableArray arrayWithArray:[title split:@" "]];
[keywords addObject:desc];
attributeSet.keywords = keywords;
NSString *identifiner = [NSString stringWithFormat:@"%@",nid];
[searchableItems addObject:[[CSSearchableItem alloc]initWithUniqueIdentifier:identifiner domainIdentifier:IOS9SearchAPIUtil_domainIdentifier attributeSet:attributeSet]];
}

[[CSSearchableIndex defaultSearchableIndex]indexSearchableItems:searchableItems completionHandler:^(NSError * __nullable error) {
if(error != nil){
NSLog(@"%@",error.localizedDescription);
}else {
NSLog(@"Items were indexed successfully");
}
}];
}
}

@end

使用方法：

[[IOS9SearchAPIUtil sharedInstance]addSearchItemsArray:@[@{@"nid":@"fin://1238796",@"title":@"fin",@"desc":@"基金",@"time":@"2014-01-01"},@{@"nid":@"fun://54fdsaf32",@"title":@"fun",@"desc":@"理财",@"time":@"2016-01-01"}]];

效果：



PS:

上传framework:



Swift版本：http://www.csdn.net/article/2015-07-16/2825222-search-apis

#define IS_IOS_9 ([[[UIDevice currentDevice] systemVersion] floatValue] >=9.0 ? YES : NO)
split就是调用NSString的 componentsSeparatedByString 方法;
