iOS Application crashes when using Admob

Question

I am currently trying to integrate my admob code into my application. But somehow the application crashes during launch without any output in the console. EXC_BAD_ACCESS. But I figured that the application crashes once it executes the following line from admob sdk.

// Initiate a generic request to load it with an ad.
[bannerView_ loadRequest:[GADRequest request]];

Since I do not get any output from the console, i did a 'bt' from the gdb and got the following output.

Can anyone tell me whats the problem here? I tried the code with my other applications and none had a problem executing the admob sdk. It would be great if someone could help me on this. I am trying very hard for the past few days and I can't figure out where's the problem. I even tried to run it using Instruments and NSZombieEnabled , somehow I think the problem is due to [GADCachedFile fileModificationDate] which I am not sure where this is called from Admob SDK

Answer 1

I was just having this clueless crash while calling that exact code in my app. Tried a few things and it didn't work, so I checked my Project Build Settings.

Under "Targets", search for the "Library Search Paths" and then I found a couple of old folders of old ads library indicated in there (I used them in previous version of my app but now decided to remove them, and so all the files are not linked to my project, but they are still there). So what I did was just delete all the unrelated directory listing in there. Did a clean all and rerun and it does not crash anymore.

Not sure my problem is similar to yours or not, but I thought I'd share this.

Good luck.
