Ios MKMapView:更改pin图像时出现问题

Ios MKMapView:更改pin图像时出现问题,ios,mkmapview,mkannotationview,Ios,Mkmapview,Mkannotationview,我正在尝试将标准pin更改为我自己的图像，但几次尝试后我一直失败我尝试过在这个论坛上找到的不同的代码和指南，但它们似乎都不起作用。我相信我将代码粘贴到我的项目中是错误的。有没有办法用我自己的图像替换普通的pin码 /.h #import <Foundation/Foundation.h> #import <MapKit/MapKit.h> @interface MapPin : NSObject <MKAnnotation> { CLLocati

请参阅我关于工作实现的其他答案。

设置IBOutlet委托：

由于您正在为MKMapView使用IBOutlet，您应该控制从序列图像板/xib文件中的MKMapView到ViewController/“文件所有者”的拖动，并从弹出窗口中选择“委派”

下面是一个涵盖创建自定义PIN的SO答案：

而且

应该是

pinView.image=[UIImage imageNamed:@"test"];

参考资料：

以下内容对我很有用：

确保已将MapKit.framework添加到项目中

确保test.png在项目中（最好在Images.xcsets中）

控制从情节提要中的mapView拖动到ViewController并连接“代理”

然后
