Best way to define private variables in Objective-C
objective-c
Solution
The "Modern Objective-C" way to do this is to declare them in your implementation block, like this:
@implementation ClassName {
int privateInteger;
MyObject *privateObject;
}
// method implementations etc...
@end
See this earlier post of me with more details.
Problem
I want to define private instance variables in MyClass.m file. It seems to me there are two ways to do it: use class extension ``` @interface HelloViewController () { int value; } ``` define in @implementation section ``` @implementation HelloViewController { int value; } ``` Which is better? I think recent Apple's coding style is to use class extension? e.g. MasterViewController.m generated by 'Master-Detail Application Template' ``` @interface MasterViewController () { NSMutableArray *_objects; } @end ```
