ios - 如何编写BOOL值的条件

Question

这是我的回应

1.{

    image = nbYijSxVXDOFGWFk8BhZUpU
    "is_food_in_time_product" = 1;
    "list_price" = "2.8";
    name = Export;

}
2.
{

    image = 0;
    "is_food_in_time_product" = 1;
    "list_price" = 1;
    name = "K\U00e4se";

}

NSString *abc5 = [abc4 valueForKey:@"image"];
NSLog(@"%@",abc5);

这里第一个响应图像是数据，第二个响应图像是无数据。然后如何编写if条件。

基于URL，您必须这样做:

    NSDictionary *responseDataDictionary = responseObject;
    //here responce object is your total data which is coming from server
    NSArray *array = [[responseDataDictionary valueForKey:@"result"] valueForKey:@"products"];
          for (NSDictionary *dict in array)
          {
               NSString *str = [dict valueForKey:@"image"];
               if([str isKindOfClass:[NSString class]])
               {
                    NSLog(@"YES");
                    //here you have to add your image as usual to another mutable array
               }else{
                    NSLog(@"NO");
                    // bool value happens means this will execute
                    // Here you have to add custom image ie.placeholder image
               }

          }
    }

就是这样
