Objective C - Call another class

Question

I use a class that returns array as the following :

%hook firstHeader
-(void)firstMethod:(id)array{
    NSLog(@"Array %@", array);

   return %orig;
}
%end

the nslog result :

array (
  "<secondHeader: 0x17a2f3c0>",
  "<secondHeader: 0x17a2f530>",
  "<secondHeader: 0x17a2f5b0>",
  "<secondHeader: 0x17a2f720>"
)

Bear with me but I may sound dumb here; how can i use the result's array object with secondHeader, As secondHeader ( or secondClass ) contains methods

Summary : First class's method returns array with objects, it wants me to use those objects with another class/header which is secondHeader

Please edit your code so that we can have a look. Also please elaborate ur question more clearly — Jamal Zafar, Jun 26 '14 at 19:09
Is it so that you want to pass the Array contents from one class to another? — Jamal Zafar, Jun 26 '14 at 19:12
%hook is a theos method to hook into classes, specifically theos/ios — osx, Jun 26 '14 at 19:17
I want to pass array objects from one class to another, NSLog results return `"`, Does the `0x17a2f5b0` stand for memory data ?, How can i use it with `secondHeader`'s methods — osx, Jun 26 '14 at 19:20

As per your comment "First class's method returns array with objects, it wants me to use those objects with another class/header which is secondHeader". Simply declare a property in secondHeader class as:

@property (nonatomic, retain) NSMutableArray * yourArray;

Synthesize it in .m File as:

@synthesize yourArray

And in your First class simple initialize the instance of secondHeader as set the value for yourArray as:

-(void)firstMethod:(id)array
{
    NSLog(@"Array %@", array);

    secondHeader * secondClass = [[secondHeader alloc] init];
    secondClass.yourArray = array;

    return %orig;
}

Once array contents are passed to secondClass, you can access the array contents by Index as:

id obj = [yourArray objectAtIndex:1];   //id is Generic data type. You should set the right data type.

Hope this will help. Ofcourse there can be other ways to pass the data, but this is the simplest way.
