IOS/Objective-C I can store objects in a local declared NSMutableArray. Why can’t I store them in same type of array in an object in another class?

Objects in Objective-C. Scanned through links that came up when I
prepped this post.

Goal: To store some number of objects
(example class ‘Trip’) in a mutable array, contained in another
object (example class ‘TourCompany’).


(portions of the
two different class interface files)


@interface
Trip : NSObject
@property (strong, nonatomic) NSString
*travelToLocation;

Trying to have my "layer" class, put 3 objects "drawObject", into
it's vector, and getting out of scope error.


Everywhere I
see they just do "vector >Class< vectorName"; and it works!

/>

layer class:


#include <vector>
#include
"DrawObject.h"
using namespace std;
class layer
{

public:
layer();
virtual ~layer();

private:
vector<DrawObject> objects;
<--------------- Error here! "'DrawObject' was not declared in this
scope"
};

Programming Languages
Hi,
I am stuck up with a problem in ActionScript 2. I am using
Flash MX 2004 on windows XP.
I have created 3 custom classes
say Parent, Child, and GrandChild. Parent class contains in it an
array of its Child objects. Similarly each Child object contains in it
an array of GrandChild objects. Also I do have one global array of all
the Parent objects.
I want to store this array to the shared
objects on specific events(say exiting the session) and then reload
them from the shared object(on next session startup). I am able to
store the global array to the shared object but when I try to retrieve
the same array from shared object, I could not do
Design Software

Below is the code



Parse.initialize("HIL42pG8FRAx9AXasyyJAg5nXI6x2IifWh30AX5I","KUKOb5pz4GEbcbGAa8GVQrBQL7ER7DsV6m0PZLOL");

var queryGroups = new Parse.Query("Group");
var arr = [];
queryGroups.find({
success: function(objects) {
for (var i = 0; i < objects.length; i++) {
var g = new Object();
g["whatsAppGroupName"] =
objects[i].get("whatsAppGroupName");
g["whatsAppGroupDescription"] =
objects[i].get("whatsAppGroupDescription");
g["entryCriteria"] = objects[i].get("entryCriteria");
g["parent"] = objects[i].get("parent");
arr.push(g);
}

for (var i = 0; i < arr.length; i++) {
console.log("whatsAppGroupName = " +
arr[i].whatsAppGroupName);
}
},
error: function(error) {
console.log("An error occured :(");
}
});


Now the problem is that for loop which prints to console works fine
inside find function but outside the find function for loop doesn't
work, seems that data is not stored in the global array. So, is there
way to store the data in the global array so that data can be used
later. I have searched on the internet and google, but not able to
find the better explanation.
