如何知道我的数组是否包含字典？

Question

我有这样的数组

   ( {
    GPSOdometerReading = "11843.6";
    "_id" =         {
        "$oid" = 5656e7175201edbb16a483f4;
    };
    acc = 0;
    )

那么如何知道我的数组是否包含字典？

谢谢.

你需要在下面的每个对象的数组和检查类上进行累积

BOOL isContainsDict = NO;
for (id value in Array){
    if ([value isKindOfClass:[NSDictionary class]]){
        isContainsDict = YES;
        break; // end since you only want to know if the array contains an instance of dictionary. if it does no need to continue the loop just break and perform the process
      }
}
