当应用程序在设备上的 Xcode 中运行时，MKMapView 使应用程序崩溃，但如果通过应用程序图标点击在设备上运行则不会

Question

I have this case where I implemented MKMapView in .xib file. I connected IBOutlet in class with MKMapView in .xib file. iOS on device is 8.3. When app is build and run by Xcode on device, it crashes when I open view controller with MKMapView, but it doesn't crash if I run the application on tap on it's icon on the device. I get no exception or error in log. It's only breaks at main. I commented code for MKMapView IBOutlet but nothing changes, only if I remove MKMapView from .xib file crash is gone. Code is written in Swift. How to fix this? Thanks for your help.

Answer 1

Hope these points may help:

1. You can try to run it in Release mode , If there there is any breakpoints issue.
2. You can check whether you are assigning delegates to the owner or not.

我有同样的问题，但我解决了它，将 mapkit.framework 添加到项目中。
