我的项目只在模拟器中运行，但不能在设备上工作，为什么？

我在地图上创build了一条折线。 并在地图视图中成功创build折线。 我的问题是，这个代码只运行模拟器。 不要在设备上工作。 我尝试了很多次，但没有在设备上工作。

Genrate的IPA和安装在我的设备，并崩溃我的应用程序。 为什么？ 只需在模拟器中运行，为什么？

为什么这是开心？ 请帮助Thankyou

Answer 1

我通过你的代码，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），所以我想你错过你的plist NSAppTransportSecurity键。

Answer 2

问题似乎与证书尝试通过设置开发证书和检查供应configuration文件。

在构build设置/目标中设置正确的证书和configuration文件然后检查。

Answer 3

尝试运行在iphone4s或5模拟器，如果它在模拟器崩溃比变化

 points[j] = CLLocationCoordinate2DMake(end_lat, end_lon); endCoordinate = CLLocationCoordinate2DMake(end_lat, end_lon); j++; 

同

 if (j<=points_count) { points[j] = CLLocationCoordinate2DMake(end_lat, end_lon); endCoordinate = CLLocationCoordinate2DMake(end_lat, end_lon); j++; } 

为什么？ 因为我们声明了CLLocationCoordinate2D points[points_count]; 所以最大的Coordinate2D是points_count但是一些纬度经度的j值高于points_count所以如果条件为j

检查它，让我知道它解决你的问题或不。
