//touch的響應方法
-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{
CGPointpoint = [[touches anyObject] locationInView:self.view];//convert point to the white layer's coordinates拿到在self.view上但同時在whiteView上的點，下面的同這里一樣，不一一解釋了
point = [whiteView.layerconvertPoint:point fromLayer:self.view.layer];
//get layer using containsPoint:
if([whiteView.layercontainsPoint:point]) {
//convert point to blueLayer’s coordinates
point = [blueLayer convertPoint:point fromLayer:whiteView.layer];
if([blueLayer containsPoint:point])
{
[[[UIAlertView alloc] initWithTitle:@"Inside Blue Layer"message:nildelegate:nilcancelButtonTitle:@"OK"otherButtonTitles:nil] show];
}else{
[[[UIAlertView alloc] initWithTitle:@"Inside White Layer"message:nildelegate:nilcancelButtonTitle:@"OK"otherButtonTitles:nil]show];
}
}
//－－－－－－－－－－華麗麗的分割線，從這里開始是我寫的點擊的方法，相對來說比上面使用起來更方便點//? ? CGPoint point=[[touches anyObject]locationInView:self.view];//? ?
