在 iPhone 中查找动画时子视图何时被触摸？

Question

我向视图添加了一个子视图。我在触摸时找到它，当它动画触摸事件时找到子视图。 这是代码...

 - (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
        UITouch *touch = [touches anyObject];
        if ([touch self]) {
            NSLog(@"View Touched");
        }
        if ([[touch view] isKindOfClass:[Baloon class]]) {
            NSLog(@"Baloon Touched");
        }
    }

您应该在气球类中实现“touchesBegan”方法，并在“touchesMove”方法中将新位置设置为气球！

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


  NSSet *allTouches = [event allTouches];
  switch ([allTouches count]) {
    case 1: {
      UITouch *touch = [[allTouches allObjects] objectAtIndex:0];

      [self setCenter:[touch locationInView:self.superview]];
    }
      break;
    default:
      break;
  }
}
