@selector - With Multiple Arguments?

Question

I have been using @selector today for the first time and have not been able to work out how to do the following? How would you write the @selector

Answer 1

Using NSInvocation as you specify you can create an NSObject category that implements

- (void)performSelector:(SEL)aSelector withObjects:(NSArray *)arguments;

Something like:

- (void)performSelector:(SEL)aSelector withObjects:(NSArray *)arguments
{
    NSMethodSignature *signature = [self methodSignatureForSelector: aSelector];
    NSInvocation *invocation = [NSInvocation invocationWithMethodSignature: signature];
    [invocation setSelector: aSelector];

    int index = 2; //
    for (NSObject *argument in arguments) {
        [invocation setArgument: &argument atIndex: index];
        index ++;
    }
    [invocation invokeWithTarget: self];
}
