我的项目只能在模拟器中运行，但不能在设备上运行，为什么？ [英] My project run only in simulator but do not work in device, why?
本文介绍了我的项目只能在模拟器中运行，但不能在设备上运行，为什么？的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我在地图上创建了一条折线。并在地图视图中成功创建多段线。
我的问题是，这段代码只运行模拟器。不要在设备上工作。我尝试了很多次，但没有在设备上工作。
生成IPA并安装到我的设备中，并崩溃我的应用程序。为什么？并简单地在模拟器中运行，为什么？
为什么这样开心？请帮助
Thankyou

解决方案
尝试在iphone4s中运行或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 ++;
随着
< pre $ 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 CLLocationCoordinate2D points [points_count];
So max Coordinate2D 是 points_count
但某些纬度经度 j 值高于 points_count 因此，如果条件为 j
请检查并让我知道它解决了您的问题或不。
I create a polyline in map. and successfully create polyline in map view. My problem is, This code run only simulator. do not work on device. I tried to many times but do not work on device.
Genrate the IPA and install in my device and crash my app. why? and simply run in simulator, why?
Why is this happining? please help Thankyou

解决方案
Try to Run in iphone4s or 5 Simulator, if it crash in simulator than change
points[j] = CLLocationCoordinate2DMake(end_lat, end_lon);
endCoordinate = CLLocationCoordinate2DMake(end_lat, end_lon);
j++;
With
if (j<=points_count) {
points[j] = CLLocationCoordinate2DMake(end_lat, end_lon);
endCoordinate = CLLocationCoordinate2DMake(end_lat, end_lon);
j++;
}
Why? Because
we declare CLLocationCoordinate2D points[points_count];
So max Coordinate2D is points_count
but some latitude longitude j value is higher than the points_count so we have to put if condition for j
Check it and let me know it it solve your problem or not.
