Objective c MKViewAnnotation自定义批注在MKMapView中添加时失去顺序

我需要在MkMapView上显示大约10个位置和相应的自定义注释图像（取决于JSON解析加载的值）。正如中所建议的，我已经创建了一个自定义注释类来存储一些数据，但是，同样，我无法获得正确的顺序：每个地图位置上的自定义图像都不符合相应解析值的正确顺序，而在UITableView中则是完美的。这是简化代码：

通信示例：

if parsed valuesID is 100 ---> annotation image must be 100.png
if parsed valuesID is 200 ---> annotation image must be 200.png
if parsed valuesID is 300 ---> annotation image must be 300.png

结果：

在UITableView上，我可以看到位置坐标和自定义图像之间的正确对应关系，并且NSLog（）提供了位置和值SID的正确对应关系。相反，在MKMapView上，自定义注释图像未按正确的顺序添加，因此我有正确的注释图像，但位于错误的位置。请再次帮助我解决这个问题，谢谢

在每个

pinView.image

行上放置一个断点，当设置image200.png时，检查坐标是什么（您可能需要记录坐标，我从来都不擅长深入挖掘调试器数据）。如果存在不匹配的情况，请查看代码的其余部分，查看可能会更改位置值的任何内容，并在其中设置断点。如果在

parseMethod

和

viewForAnnotation

之间触发该断点，则可能是您的罪魁祸首。

在viewForAnnotation中，为所有三个ifs分配了相同的图像。这是故意的吗？是的@annakarenia，这是我的转录错误：现在我已经纠正了它，并添加了UITableView委托，以提供更精确和清晰的代码。谢谢另一个打字错误：

annotation2.valueIDMyAnnotation2=

应该是

annotation2.valuesIDMyAnnotation2=

（在

ID

之前缺少

s

）--如果复制并粘贴准确的代码而不是重新键入，效果会更好。无论如何，在发布的代码中没有明显的问题。唯一的可能性是

坐标

数组（表视图正在使用）与

位置

数组（注释正在使用）不匹配。哦，但这绝对是难以置信的。你在addAnnotations方法中看到for（）循环了吗？在NSLog结果中，我可以读取，例如：“100-坐标lat1-lon1”，但在MKMapView上，具有lat1和lon1坐标的位置具有注释image200.png。。。我快昏了头！谢谢@Craig，我曾尝试添加断点，但同样无法理解：在

[map addAnnotation:annotation2]

之前，我已按正确顺序对所有数据进行了排序，正如您在NSLog结果中所看到的那样，因此我无法获得问题。断点的结果是什么？设置图像时，坐标在哪里，正确还是错误？嗯，@AnnaKarenina是正确的：经过几天的代码调试，我注意到只有在某些位置，

坐标

数组与正确的

位置

不匹配。。。问题已解决。您是否愿意解释两个数组如何不匹配？很简单，这是我的错误：我使用错误的纬度和经度值声明了一些

MakeLocation（lat，lon）

，因此相应的解析值与地图上的正确位置不匹配（在parseMethod中，要解析valuesID，我不使用lat、lon，而是使用相应的GeoNamesID数组）。
