Declare a block method parameter without using a typedef

Question

Is it possible to specify a method block parameter in Objective-C without using a typedef? It must be, like function pointers, but I can\'t hit on the winning syntax witho

Answer 1

Even more clear !

[self sumOfX:5 withY:6 willGiveYou:^(NSInteger sum) {
    NSLog(@"Sum would be %d", sum);
}];

- (void) sumOfX:(NSInteger)x withY:(NSInteger)y willGiveYou:(void (^) (NSInteger sum)) handler {
    handler((x + y));
}
