I have a class with a mutable array. But from outside it should be just a
read-only non-mutable array.
My current solution:
MyClass.h file contains:
@property (readonly, nonatomic) NSArray *externalArray;
and MyClass.m file has:
@interface MyClass()
@property (strong) NSMutableArray *internalArray;
@end
@implementation MyClass
- (NSArray *) externalArray { return self.internalArray; }
@end
Is there a better (more elegant) way?
And another question:
I have a struct property like:
@property (assign) some_Struct_t myStruct;
But when I write:
self.myStruct.something = 7;
I get told "Expression is not assignable". (Xcode 4.4.1)
This works:
some_Struct_t temp = self.myStruct;
temp.something = 7;
self.myStruct = temp;
But this is not really nice. There sure must be a better way.
Gerriet.
