iOS 扩大按钮的点击范围

iOS 扩大按钮的点击范围

• 首先要自定义一个按钮 重写方法
  -(BOOL)pointInside:(CGPoint)point withEvent:(UIEvent *)event
  {
  CGRect bounds = self.bounds;
  CGFloat widthDelta = 44.0 - bounds.size.width;
  CGFloat heightDelta = 44.0 - bounds.size.height;
  bounds = CGRectInset(bounds, -0.5 * widthDelta, -0.5 * heightDelta);
  return CGRectContainsPoint(bounds, point);
  }

• 按照常理创建按钮
