我在地图中创建折线。并在地图视图中成功创建折线。 我的问题是，这段代码只运行模拟器。不要在设备上工作。我试过多次，但不在设备上工作。
生成IPA并安装在我的设备中并崩溃我的应用程序。为什么？并且只是在模拟器中运行，为什么？
为什么这样快乐？请帮忙 三江源

我查看你的代码并在模拟器中运行，它会显示警告CFNetwork SSLHandshake失败（-9824）NSURLSession / NSURLConnection HTTP加载失败（kCFStreamErrorDomainSSL，-9824），所以我想你错过了你的plist中的NSAppTransportSecurity键。 / p>

证书似乎通过设置开发证书并检查配置文件来解决问题。
在构建设置/目标中设置正确的证书和配置文件，然后检查。

答案 2 :(得分：0)
尝试在iphone4s或5模拟器中运行，如果它在模拟器中崩溃而不是更改
points[j] = CLLocationCoordinate2DMake(end_lat, end_lon);
endCoordinate = CLLocationCoordinate2DMake(end_lat, end_lon);
j++;
使用
if (j<=points_count) {
points[j] = CLLocationCoordinate2DMake(end_lat, end_lon);
endCoordinate = CLLocationCoordinate2DMake(end_lat, end_lon);
j++;
}
为什么呢？因为
我们声明CLLocationCoordinate2D points[points_count];
因此，最高Coordinate2D为points_count
但是某些纬度经度j值高于points_count因此我们必须将j的条件置于
检查并让我知道它解决了您的问题。
