setUseDefaultModalPresentationStyle - unrecognized selector sent to instance

[jathu]

Hey there, the library works perfectly on iOS8+. However on iOS 7, I keep getting this error:

2015-10-08 11:27:50.762 APPNAME[3104:60b] -[AFBlurSegue setUseDefaultModalPresentationStyle:]: unrecognized selector sent to instance 0x17dc01b0

*** First throw call stack:

libc++abi.dylib: terminating with uncaught exception of type NSException

I can't seem to find this method in the library, so do you know what's causing the problem?
