Compatibitlity Issue with iOS 8.1?

[HermannK]

This occurred after we migrated to iOS 8.1. However, I have not double checked whether this is really related to iOS 8.1

static NSString *str2 = @"ResourceRules.plist";
[manager fileExistsAtPath:([NSString stringWithFormat:@"%@/%@", bundlePath, str2])]
returns FALSE.
As a result the method isCracked returns true which causes a false alarm.

We found in the release notes
https://developer.apple.com/library/ios/releasenotes/General/RN-iOSSDK-8.0/index.html#//apple_ref/doc/uid/TP40014223
the following:
"The file system layout of app containers has changed on disk. Rather than relying on hard-coded directory structure, use the NSSearchPathForDirectoriesInDomains function or the URLForDirectory:inDomain:appropriateForURL:create:error: method of the NSFileManager class. See Accessing Files and Directories in File System Programming Guide"

As of iOS 8.1 / OSX 10.10, applications now longer create a resourcerules plist by default, meaning this code would be mostly invalid as a missing resourcerules.plist no longer indicates that the application has been tampered with. If you did want to add this in though, it can be done through going to Build Settings > Code Signing > 'Code Signing Resource Path' and adding '$(SDKROOT)/ResourceRules.plist' as the value.

@Jordo96 That fix on debug. But is that going to work on production?

@HermannK @Jordo96 Do you know if that would work on production? Can't figure this out and don't want to make a bad version.

[Jordo96]

Probably best to just remove the check from the code - after all, it is no longer really a definitive way to determine if the application has been compromised if it is no longer actually needed. If you still wanted to keep the check in the code, then I'm pretty confident it would work in production.

@Jordo96 How confident you are? My app have been compromised straight after removing this check. Maybe I shall add an analytics event just to make sure before doing any serious action...
