MKMapView 因 EXC_BAD_ACCESS 崩溃

发布于 2024-10-02 17:03:42 字数 1119 浏览 0 评论 0原文

我有以下代码行激活断点

[mapView addAnnotations:grabinstance.itemArray];

此随机崩溃。 rabinstance.itemArray 始终被完全填充，并且当时永远不会改变，因为只有在数组已满时才会调用这段代码。这次已确认数组中有 323 个项目。

NSZombieEnabled 也没有找到任何东西。

下面是回溯，上面的行是 1154 行。

原文

I have the following line of code which activates the breakpoint

[mapView addAnnotations:grabinstance.itemArray];

This crashing randomly. grabinstance.itemArray is fully populated always and is never changing at the time due to this bit of code only being called once the array is full. This particular time this was confirmed as 323 items in the array.

NSZombieEnabled doesn't find anything at all either.

The backtrace is below and line 1154 is the line above.

您应该使用CLLocationCooperative2DIsValid()检查您的注释：

if (CLLocationCoordinate2DIsValid(place.coordinate)) {
    [_mapView addAnnotation:place];
} else {
    NSLog(@"place %@ has invalid coordinates", place.name);
}

You should check your annotations using CLLocationCoordinate2DIsValid():

if (CLLocationCoordinate2DIsValid(place.coordinate)) {
    [_mapView addAnnotation:place];
} else {
    NSLog(@"place %@ has invalid coordinates", place.name);
}
