iOS 11.1.2: worked ok on 8f701f8b4b8ec8a3468144ed9dbcc3904f8651d1 the code causing a crash:

[JFGSDK connectWithVid:@"" vKey:@"" ForWorkDir:[[NSHomeDirectory() stringByAppendingPathComponent:@"Documents"] stringByAppendingPathComponent:@"jfg"]];

NSPathStore2 is a subclass of NSString that is used to create strings that contain paths. For all intents and purposes, you should pass in an NSString.

KonstantinRitt commented 6 years ago

And that's exactly what I'm passing to [JFGSDK connectWith]!

The question is: where that unrecognized selector jfgUTF8String of NSPathStore2 cames from?

Step-by-step debugging shows that Vid and vKey are applied successfully at JFGSDK shared instance initialization, then the problem occurs when applying the passed ForWorkDir. Note that I was trying ForWorkDir:@"" as well and that caused exactly the same result.

The base of a NSString expansion, used to determine whether the string is nil

yangli996 commented 6 years ago

Please cast the parameters to NSString

KonstantinRitt commented 6 years ago

The connectWith method has 3 NSString parameters. I'm passing 3 NSSting parameters to it. How could casting NSString to NSString solve the issue?!

The code above worked just fine on commit 8f701f8 and doesn't work after that commit.

Plz take a look at /Users/yangli/git/3.0-sdk/src/cylan/sdk/object-c/JFGSDK/JFGSDKSource/JFGSDKBase/JFGSDKBase.mm:175 - find the problem and fix it.

Is there any other info I can provide that will help you finally understand the problem and fix it?

KonstantinRitt commented 6 years ago

Fixed in 380f2d2ccaeb81649caa138506be4529266a1826, thanks.
