Problem with CGRectInterectsRect

i have created method sets uiimageview's position 35 pixels away uiimageview called mainsprite.

code:

 -(ibaction)hit{     [self hitdummies];     if (direction == 1) {         [self hitdummies];         hitbox.center = cgpointmake(mainsprite.center.x+30, mainsprite.center.y);     }     if (direction == 2) {         [self hitdummies];         hitbox.center= cgpointmake(mainsprite.center.x,mainsprite.center.y+30);     }     if (direction == 3) {         [self hitdummies];         hitbox.center = cgpointmake(mainsprite.center.x-30, mainsprite.center.y);     }     if (direction == 4) {         [self hitdummies];         hitbox.center = cgpointmake(mainsprite.center.x, mainsprite.center.y-30);     }

it move want. there void method tests if hitbox intersects uiimageview: dummies.

code:

-(void)hitdummies{     if (cgrectintersectsrect(hitbox.frame, dummies.frame)) {         nextconvobut.enabled = yes;         nextconvobut.hidden = no;     } }

as can see calling method in -(ibaction)hit. keep in mind "hit" linked "touch down".
if need see more code ask

 

ok, what's question?
