用谓词搜索实现本地搜索

- (void) textFieldDidChange:(UITextField*) TextField{
    NSString *conditionStr = TextField.text;
    NSLog(@"+++++%@", conditionStr);
    // 2. 创建谓词，准备进行判断的工具
    NSPredicate *predicate = [NSPredicate predicateWithFormat:@"self.pinyin CONTAINS [CD] %@ OR self.appName CONTAINS [CD] %@", conditionStr, conditionStr];
    searchMuArray = [NSMutableArray arrayWithArray:[_s_allNameArray filteredArrayUsingPredicate:predicate]];
    NSLog(@" searchMuArray  = %@", searchMuArray);
    
    [myTableView reloadData];
    
}
