performSelector:withObject:afterDelay: won't accept my custom UIImageView pointers, why not?

Question

Okay guys... Hopefully this will be another quickie.

I have a class MonsterView, extending UIImageView, extending NSObject.

I have declared a MonsterView pointer called myMonster that contains an object of class MonsterView and looks something like this...

MonsterView* myMonster = [monsterArray objectAtIndex:0];

Now the pointer myMonster points to an object of class MonsterView.

I have a method like:

-(void) takeTurnHostile:(MonsterView*) monster
{
     // Do Stuff
}

I want to call this method by using performSelector... Like THIS:

[self performSelector:@selector(takeTurnHostile) withObject:myMonster afterDelay:0.1];

The bloody machine will not have any such nonsense. Why in the name of all that is good and holy can't I do this?

More importantly, how -COULD- I do this?

Thanks, guys! J-Rock

Answer 1

@selector(takeTurnHostile)

should be

@selector(takeTurnHostile:)

because your selector takes an argument, and the colon is part of the selector name.

Answer 2

Missing colon in the selector...

[self performSelector:@selector(takeTurnHostile:) withObject:myMonster afterDelay:0.1];

Answer 3

it should be @selector(takeTurnHostile:). You've forgot the colon

Answer 4

As H2CO3 said you must provide the colon:

takeTurnHostile:

The colon indicates that the method you are calling has 1 parameter. Currently without the colon you are saying to run the method:

-(void) takeTurnHostile
{
}
