I have the following:
@implementation DataSource
+ (NSArray *)someData
{
static NSArray *data = nil;
if (!data) {
data = [[NSArray arrayWithObjects:..., nil] retain];
}
return data;
}
@end
Is there a way to access the class method from the class it self?
NSArray *array = [DataSource someData];
Yes. Inside a class method like your someData you can call another class method like
[self anotherClassMethod].
Here self refers to class.
In other class methods, you can call it as [self someData]. From instances of the class, you can call it as [[self class] someData] (this has the nice property that subclasses can override it and their implementations will automatically be used as appropriate). From outside the class, you can call it as [DataSource someData].
BTW, if this is actually meant to be the data source for some Cocoa or Cocoa Touch class such as NS/UITableView, you should probably implement the class as a singleton instead of making the class itself the data source, because using classes as data sources is not well-tested and the lack of instance variables will probably become a pain as your program grows.
a static method can be called with name of class. Above static method return type NSArray so we can use anywhere
NSArray *Arr=[DataSource someData];
