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);

这里第一响应图像来的数据，第二响应图像没有data.Then如何写的中频条件。

Answer 1

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
               }

          }
    }

就这样干杯

Answer 2

NSNumber * isSuccessNumber = (NSNumber *)[abc4 valueForKey:@"image"];
if([isSuccessNumber boolValue] == YES)
{
  NSLog(@"Image is available");
} else {
  NSLog(@"Image is not available");
}

你的反应是这样的

第一条件：

 NSDictionary *r1 = @{@"bool" : @(1)};

NSNumber * isSuccessNumber = (NSNumber *)[r1 valueForKey:@"bool"];
if([isSuccessNumber boolValue] == YES)
{
    NSLog(@"Image is available");
} else {
    NSLog(@"Image is not available");
}

Output1

图像可用

第二条件：

NSDictionary *r1 = @{@"bool" : @(0)};

NSNumber * isSuccessNumber = (NSNumber *)[r1 valueForKey:@"bool"];
if([isSuccessNumber boolValue] == YES)
{
    NSLog(@"Image is available");
} else {
    NSLog(@"Image is not available");
}

Output2

图像不可用

Answer 3

您存储的是Dictionary在Array中。

//Here index is an integer value, showing the index of an array responseArray.
if[responseArray[index][@"image"] intValue]!=0){

    //Load image
}else{
    //Do not load image
}
