Two views with multitouch - ios

Question

I should manage two different views inside my main view; I want detect the exact number of finger inside my views, that is if I have four fingers inside "first view" I want a var that say me a value = 4, and if I have 3 fingers in "second view" I want another var that say me a value = 3. I show you my code that don't work fine.
- (void) touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event{
UITouch *touch = [[event allTouches] anyObject];
CGPoint touchLocation = [touch locationInView:self.view];
NSLog(#"cgpoint:%f,%f", touchLocation.x, touchLocation.y);
if (CGRectContainsPoint(view1.frame, touchLocation)){
NSLog(#"TOUCH VIEW 1");
totalTouch1 = [[event allTouches]count];
NSLog(#"TOTAL TOUCH 1:%d", totalTouch1);
}
else if (CGRectContainsPoint(view2.frame, touchLocation)){
NSLog(#"TOUCH VIEW 2");
totalTouch2 = [[event allTouches]count];
NSLog(#"TOTAL TOUCH 2:%d", totalTouch2);
}
}
With my code if I begin to lay my finger in "first view", it's all ok, but for example if I lay my fourth finger inside second view my code enter in first "if" and say that my finger is yet in first view. I don't understand the problem.

[[event allTouches] anyObject]; is fetching you only one of the touches.
you need to iterate over all the touches like so:
- (void) touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event{
int touch1 = 0;
int touch2 = 0;
NSArray *touches = [[event allTouches] allObjects];
for( UITouch *touch in touches ) {
CGPoint touchLocation = [touch locationInView:self.view];
NSLog(#"cgpoint:%f,%f", touchLocation.x, touchLocation.y);
if (CGRectContainsPoint(view1.frame, touchLocation)){
NSLog(#"TOUCH VIEW 1");
touch1 += 1;
NSLog(#"TOTAL TOUCH 1:%d", totalTouch1);
}
else if (CGRectContainsPoint(view2.frame, touchLocation)){
NSLog(#"TOUCH VIEW 2");
touch2 += 1;
NSLog(#"TOTAL TOUCH 2:%d", totalTouch2);
}
}
NSLog(#"Total touches on view 1: %d", touch1);
NSLog(#"Total touches on view 2: %d", touch2);
}
