在NSMutableArray中存储CLLocationCoordinates2D [英] Storing CLLocationCoordinates2D in NSMutableArray

问题描述

经过一番搜索，我得到了以下解决方案：
引用

After some searching, I got the following solution : reference.

CLLocationCoordinate2D* new_coordinate = malloc(sizeof(CLLocationCoordinate2D));
new_coordinate->latitude = latitude;
new_coordinate->longitude = longitude;
[points addObject:[NSData dataWithBytes:(void *)new_coordinate
length:sizeof(CLLocationCoordinate2D)]];
free(new_coordinate);

并以以下方式访问它：

CLLocationCoordinate2D* c = (CLLocationCoordinate2D*) [[points objectAtIndex:0] bytes];

但是，有人声称这里存在内存泄漏吗？谁能建议我泄漏在哪里以及如何修复。此外，还有更好的方法在NSMutableArray中存储CLLocationCoordinate2D列表吗？由于我是Objective C新手，请提供示例代码。

However, someone claims that there is a memory leak here? Can anyone suggest me where is the leak and how to fix it. Further, is there a better way of storing a list of CLLocationCoordinate2D in NSMutableArray? Please give sample code since I am an Objective C newbie.

推荐答案

没有泄漏，只是浪费堆内存。

There's no leak, just a waste of heap memory.

您可以使用

CLLocationCoordinate2D new_coordinate;
new_coordinate.latitude = latitude;
new_coordinate.longitude = longitude;
[points addObject:[NSData dataWithBytes:&new_coordinate length:sizeof(new_coordinate)]];
