Objective C - Calling a class method on the main thread?

Question

How can I call a CLASS METHOD on the main thread? Something like:

[SomeClass performSelectorOnMainThread:staticMethod withObject:nil];

Please don't tell me to create a regular method to call this class method. That would be an obvious solution, but not clean.

Thanks

Answer 1

[SomeClass performSelectorOnMainThread:staticMethod withObject:nil waitUntilDone:NO];

Yes, performSelectorOnMainThread:withObject:waitUntilDone: is not a class method.

Yes, it is an instance method on NSObject .

Yes, all Class objects are instances of NSObject . ( I'm not kidding! )

You could also do:

dispatch_async(dispatch_get_main_queue(), ^{
  [SomeClass doClassyThingWithObject:object1 andDiddleyDoo:foo];
});

Answer 2

How about:

NSInvocationOperation *operation = [[NSInvocationOperation alloc] initWithTarget:[SomeClass class] selector:@selector(SomeClass) object:nil];
[[NSOperationQueue mainQueue] addOperation:operation];
