来自foursquare场地搜索的iphone-parse响应

Question

我正在Iphone工作。我已经完成了几乎所有在iPhone应用程序中进行foursquare集成所需的工作。 现在我试图在此应用程序中添加Venue搜索功能。

 code-: 

    NSMutableString *url=[[NSMutableString alloc] initWithFormat:@"https://api.foursquare.com/v2/venues/search?ll=26.8606200,75.761608&client_secret=XXXXXX&client_id=XXXXXX"]; 
    NSLog(@"%@",url); 
    NSURL *url1=[[NSURL alloc] initWithString:[url stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]]; 
    NSLog(@"%@",url1); 
    NSDictionary *dicVenue=[self objectWithUrl:url1]; 
    NSLog(@"%@",dicVenue); 



This is my response for foursquare Venues search:- 
of this line-- NSLog(@"%@",dicVenue);

您可以使用json解析器轻松解析值。查看Foursquare场地搜索分析的以下代码。

-(NSMutableArray*)returnVenuesDetails:(NSDictionary*)result{ 
    NSArray *groupsArray = [[(NSDictionary*)result objectForKey:@"response"] objectForKey:@"groups"]; 

       NSArray *itemsArray; 
       if([groupsArray count] > 0){ 
        itemsArray = [[groupsArray objectAtIndex:0] objectForKey:@"items"]; 

        NSMutableArray *resultArray = [NSMutableArray array]; 
        if([itemsArray count] > 0){ 
         for (int i=0; i<[itemsArray count]; i++) {  

          NSMutableDictionary *resultDictionary=[[NSMutableDictionary alloc] init]; 

          NSString *venueId = [[itemsArray objectAtIndex:i] objectForKey:@"id"]; 
          NSString *venueName = [[itemsArray objectAtIndex:i] objectForKey:@"name"]; 
          [resultDictionary setObject:venueId forKey:@"venueId"]; 
          [resultDictionary setObject:venueName forKey:@"venueName"]; 

          //Get Stats details 
          NSDictionary *stats = [[itemsArray objectAtIndex:i] objectForKey:@"stats"]; 
          NSString *checkinsCount = [stats objectForKey:@"checkinsCount"]; 
          NSString *tipCount = [stats objectForKey:@"tipCount"]; 
          NSString *usersCount = [stats objectForKey:@"usersCount"]; 

          [resultDictionary setObject:checkinsCount forKey:@"checkinsCount"]; 
          [resultDictionary setObject:tipCount forKey:@"tipCount"]; 
          [resultDictionary setObject:usersCount forKey:@"usersCount"]; 

          NSArray *catArray = [[itemsArray objectAtIndex:i] objectForKey:@"categories"]; 

          if([catArray count]> 0){ 
           //Get Category List 
           NSDictionary *categoryDic = [catArray objectAtIndex:0]; 
           NSLog(@"categoryDic ----- = %@",categoryDic); 

           [resultDictionary setObject:[categoryDic objectForKey:@"icon"] forKey:@"icon"]; 
           [resultDictionary setObject:[categoryDic objectForKey:@"id"] forKey:@"catId"]; 
           [resultDictionary setObject:[categoryDic objectForKey:@"name"] forKey:@"catName"]; 

          } 
          //Add dictionary into Array 
          [resultArray addObject:resultDictionary]; 
         } 


         //Use this resultArray for display the Search details 
         for (int i=0; i<[resultArray count]; i++) { 
          NSString *venueName=[[resultArray objectAtIndex:i] objectForKey:@"venueName"]; 
          NSString *checkins=[[resultArray objectAtIndex:i] objectForKey:@"checkinsCount"]; 

          NSLog(@"venueName = %@",venueName); 
          NSLog(@"checkins = %@",checkins); 

         } 
        } 
      return resultArray; 
       } 
     return [NSMutableArray array]; 
     }
