Question

I’m looking to create a class in Objective-C for an iOS project that is focused on fetching data. I’m familiar with how classes normally work, setter and getter methods and variables. However, for this class since it’s only performing a function (returning NSMutableArrays) I don’t want to have to create an instance of the class to use the methods inside the class.

Any idea how I can do this neatly and efficiently?

Answer 1

You want to make class methods?

@interface Foo : NSObject {}
+(NSMutableArray*)someClassMethod:(id)params;
@end

...

@implementation Foo
+(NSMutableArray*)someClassMethod:(id)params {
   // whatever implementation 
   return nil;
}
@end

...

NSMutableArray* array = [Foo someClassMethod:nil];
