有没有办法比较CGPoints？

Question

我想要这样的东西:

CGPoint a = CGPointMake(1, 1);
CGPoint b = CGPointMake(1, 1);

if ([CGHelperClass compareCGPoint:a to:b]){
  //do something
}

我知道写自己是微不足道的,但我很好奇它是否已经存在于某个地方.

Answer 1

CGPointEqualToPoint:返回两个点是否相等.

bool CGPointEqualToPoint (
   CGPoint point1,
   CGPoint point2
);
