objective-c - 如何在 Objective-C 中形成 CGPoint 数组？

Question

我想得到这个结构:

CGPoint addLines1[] =
{
    CGPointMake(30.0, 150.0),
    CGPointMake(41.67, 145.19),
    CGPointMake(53.33, 103.25),
    CGPointMake(65.0, 131.67),
    CGPointMake(76.67, 106.11),
    CGPointMake(88.33, 110.20),
    CGPointMake(100.0, 111.54),
    CGPointMake(111.67, 112.13),
    CGPointMake(123.33, 115.66),
    CGPointMake(135.0, 123.7),
    CGPointMake(146.67, 125.53),
    CGPointMake(158.33, 115.1),
    CGPointMake(170.0, 69.38),
    CGPointMake(181.67, 112.47),
    CGPointMake(193.33, 65.1),
    CGPointMake(205.0, 103.33),
    CGPointMake(216.67, 92.6),
    CGPointMake(228.33, 54.76),
    CGPointMake(240.0, 79.66),
    CGPointMake(251.67, 53.81),
    CGPointMake(263.33, 56.81),
    CGPointMake(275.0, 88.19),
    CGPointMake(286.67, 74.81),
    CGPointMake(298.33, 28.1),
    CGPointMake(310, 20.0),
};

为了做一些计算和绘制数据。

我有 CGPoint *lines = appDelegate.averageResponseTimePoints;

如何从 *lines 生成数组 addLines[]？

对于 iOS:

创建数组:

NSArray *myCGPointArray = @[[NSValue valueWithCGPoint:CGPointMake(30.0, 150.0)],[NSValue valueWithCGPoint:CGPointMake(41.67, 145.19)]];

获取第一个 CGPoint 对象:

CGPoint myPoint = [myCGPointArray[0] CGPointValue];
