Ios 在MKMapView上尝试多个批注时发生SIGABRT错误

我一直在使用MKMapView，并在地图上放置注释钉。我正在努力在地图上为30个不同的位置放置30个PIN，并确保在添加每个附加位置后运行iPhone SDK。然后，不知从何而来，它开始崩溃，给我一个可怕的“西格伯特”。AG

我知道这可能是我语法上的一个小错误，但由于我刚刚复制和粘贴了以前有效的代码，所以我不知所措。我正在考虑使用MKCoordinateRegionMake使一切变得更加简洁。我读到这可能是一个选项，但我已经进入了大约10家商店，因此需要花费大量时间来切换，如果这是一个快速修复，我不想这样做

除了一个坐标外，我把所有的坐标都取出来，结果成功了。然后我又加了一个回来，它工作了，等等。出于某种原因，它工作了很多次，但有时它会锁定和崩溃。我认为这只是一个特定位置的问题，但它似乎从来没有任何位置的语法问题，特别是。所以现在我不知道是什么导致了它

我想这可能是一个分配和释放的问题，我做得不对？我曾试图在编写代码期间释放某些分配的空间，但问题仍然存在。我还尝试在代码执行期间不释放分配的空间，这也是同样的问题

这是我正在使用的代码，所有代码有时都在使用，因此我在MillersLocations文件中正确设置了标题、副标题和坐标：

错误线程1：程序接收信号SIGABRT。总是发生在线路上：

[地图视图设置区域：store57动画：是]

或者在store90上。也有其他商店发生过这种事，但总是在那条线上。没有我确定的押韵或理由

感谢所有能帮忙的人！抱歉如果我有点啰嗦，我只是想确保我包括了你需要帮助的任何信息

编辑

一旦我正确地合成了我创建的MKMapView Outlet，然后获得了发布它的代码[mapView release]；，它就工作了；。我假设地图视图会自行发布，这可能是导致错误的原因

---

它工作得很好，然后我去添加另一个注释，它又崩溃了。当我删除新注释时，它会起作用，因此添加更多注释时会出现问题。AG。感谢您的帮助。谢谢。

SIGABRT最可能的原因是store49的区域无效，导致NSInvalidArgumentException和SIGABRT

对于store49和之后的所有商店，未设置longitudeDelta。 只有latitudeDelta被设置了两次

将重复的latitudeDelta设置修复为longitudeDelta

另一个问题是：

[MillersLocations release];

这试图调用MillersLocation类的release，而不是您正在创建的类的实例。所有这些行都应更改为以下内容：

[ann56 release];

此外，不必每次都创建区域来设置注释。例如，您可以这样做：

MillersLocations *ann56 = [[MillersLocations alloc]init];
ann56.title = @"Store #56";
ann56.subtitle = @"Come check us out!";
ann56.coordinate = CLLocationCoordinate2DMake(36.8605679, -76.2866713);
[mapView addAnnotation:ann56];
[ann56 release];

添加所有注释后，可以创建一个包含所有注释的区域（如果需要），或者只显示最后一个注释，然后在末尾调用setRegion一次

此外，您可能希望将存储存储在plist中，并在plist中循环以创建注释，而不是在代码中单独创建注释

---

最后，您不应该删除[mapView版本]；来自dealloc，即使是IBOutlet。

哇，非常感谢。我不敢相信我忽略了latitudeDelta问题的语法错误。这是一个很大的帮助，非常感谢。对于阅读本文寻求帮助的任何人来说，您必须添加并导入CoreLocations框架以使用CLLocationCoordinate2DMake。
