【IOS工具类】IOS9的CoreSpotlight(OC语言)

标签：

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>

            attributeSet.title = title;

            }else {
                NSLog(@"Items were indexed successfully");
            }
        }];
    }
}

@end

[[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"}]];

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;

NSString+Wapper.h 类参照：http://blog.csdn.net/coooliang/article/details/45871149
