Question

I want to call a method which returns two values

basically lets say my method is like the below (want to return 2 values)

NSString* myfunc
{
   NSString *myString = @"MYDATA";
   NSString *myString2 = @"MYDATA2";
   return myString;
   return myString2;        
}

So when i call it, i would use??

NSString* Value1 = [self myfunc:mystring];
NSString* Value2 = [self myfunc:mystring2];

I guess im doing something wrong with it, can anyone help me out?
Thanks

You have a few options:

• NSArray: Just return an array. Pretty simple.
• Pointers: Pass in two pointers, and write to them instead of returning anything. Make sure to check for NULL!
• Structure: Create a struct that has two fields, one for each thing you want to return, and return one of that struct.
• Object: Same a structure, but create a full NSObject subclass.
• NSDictionary: Similar to NSArray, but removes the need to use magic ordering of the values.
