iOS笔记--多点触碰的时候如何获取其中的某一次点击事件

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event{

NSInteger i=0;

for (UITouch *touch
in touches) {

UIImageView *imageview=[[UIImageView
alloc]initWithImage:self.images[i]];

CGPoint location=[touch
locationInView:self.view];
[imageview
setCenter:location];
[self.view
addSubview:imageview];
i++;
}

}
