I recently upgraded the RevMob SDK of my cocos2d project, using Xcode 4.5. Below is a code to show what I have done:
#import <StoreKit/StoreKit.h>
#import <RevMobAds/RevMobAds.h>
- (void) applicationDidFinishLaunching:(UIApplication*)application{
[RevMobAds startSessionWithAppID:@"my app id"];
//some code here...
}
On running the project, on device or simulator, the app crashes with this error:
+[RevMobAds startSessionWithAppID:]: unrecognized selector sent to class
However, one thing which might be useful, is that when I added the RevMob framework to my Xcode, it gave me compilation errors (using LLVM GCC 4.2) for which I followed this answer.
This method was included in version 5.0.0 (RevMob changelog), so make sure that the framework that you are using is at least 5.0.0.
