Detect collision between multiple UIImageViews that are animated with the same name
I am trying to detect the collision between a falling/animated UIImageView that is created every second with an NSTimer. Here's the code:
-(void)newobject{
int randomx = 76+ arc4random() %(290);
int randomDuration = 2+ arc4random() %(6);
int randomImage = 1+ arc4random() %(3) ;
NewObject = [[UIImageView alloc] initWithFrame:CGRectMake(randomx,0,36 ,36)];
UIImage *imag = [UIImage imageNamed:@"ball.png"];
[NewObject setImage:imag];
[self.view addSubview:NewObject];
numberofObjects += 1;
NewObject.tag = numberofObjects;
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:randomDuration];
[UIView setAnimationBeginsFromCurrentState:YES];
[UIView setAnimationDelegate:self];
[UIView setAnimationDidStopSelector:@selector(animationDone:finished:context:)];
NewObject.frame = CGRectMake(randomx, 300,NewObject.frame.size.width,NewObject.frame.size.height);
[UIView commitAnimations];
}
That code crates a new UIImageView with the name NewObject and animates it down the screen. To detect the collision I have another NSTimer that is called every 1.0/60. Here's the code:
-(void)Collison{
for (int i = 1; i < numberofObjects; i++) {

[image viewWithTag:i];
CALayer *layer = image.layer.presentationLayer;
CGRect NewObjectFrame = layer.frame;
CALayer *layer2 = Sprint.layer.presentationLayer;
CGRect SprintFrame = layer2.frame;
if (CGRectIntersectsRect(NewObjectFrame, SprintFrame)) {
[self StopTimers];
NSLog(@"hello");
}
}
}
The problem is that the console says "It works" but the UIImage didn't collide and I can collide the character with the image but the console says nothing and at the same time if I try to collide the character with the UIImageView it works. What i'am trying to say is that it's not reliable. Can someone help?
update: I edited the code but now it detecting the last uiimageview that is added.
ok well i got it. It's simple so all you need to do is make an NSMutableArray and check the array for collision with a for loop.
