如何在阵列中存储CGPoint

var cgPointArray: [CGPoint] = []

// 添加CGPoint对象到数组中
let point1 = CGPoint(x: 10, y: 20)
cgPointArray.append(point1)

let point2 = CGPoint(x: 30, y: 40)
cgPointArray.append(point2)

// 访问数组中的CGPoint对象
print("第一个点的坐标：\(cgPointArray[0])")
print("第二个点的坐标：\(cgPointArray[1])")

NSMutableArray *cgPointArray = [NSMutableArray array];

// 添加CGPoint对象到数组中
CGPoint point1 = CGPointMake(10, 20);
NSValue *point1Value = [NSValue valueWithCGPoint:point1];
[cgPointArray addObject:point1Value];

CGPoint point2 = CGPointMake(30, 40);
NSValue *point2Value = [NSValue valueWithCGPoint:point2];
[cgPointArray addObject:point2Value];

// 访问数组中的CGPoint对象
CGPoint firstPoint = [[cgPointArray objectAtIndex:0] CGPointValue];
CGPoint secondPoint = [[cgPointArray objectAtIndex:1] CGPointValue];
NSLog(@"第一个点的坐标：{%f, %f}", firstPoint.x, firstPoint.y);
NSLog(@"第二个点的坐标：{%f, %f}", secondPoint.x, secondPoint.y);
