我的iPhone应用程序可以在设备上运行，但不能在模拟器上运行

Question

My app works okay on the device, but not the simulator. When I run it on the simulator I get no errors or anything. The app just dies a second after being launched. Does this really matter? Should I be concerned?

In fact, the only reason I wanted to run the simulator is to get an idea of how my app runs on the iPad (of which I don't physically own). What do we think?

Answer 1

If there are no obvious logs, one thing you can do is to add some NSLog statements to each method.

I use these:

NSLog(@"%s", __FUNCTION__);

Then, when I'm done debugging, I comment them out. That way I can see what was the last method the app entered before it stopped.

Answer 2

您应始终调试应用程序运行不正常的原因，因为这可能是更严重问题的根本原因，例如内存损坏，这将导致该应用程序在登月后一直对每个客户崩溃相位变化只是一点点。

NSZombiesEnabled参数还有助于查找错误： http : //iosdevelopertips.com/debugging/tracking-down-exc_bad_access-errors-with-nszombieenabled.html

Answer 4

Sometimes the simulator gets confused. Delete the content of ~/Library/Application Support/iPhone Simulator/6.1/Applications or thereabouts and try it again.
