Correct isStarted flag in setupSession and stopHandler method.

In previous version, startHandler and stopHandler need in pairs. The upBlock/downBlock will trigger many times with single volume up event when startHandler execute more than once.

@gliyao Am I missing something here? 56: [self startHandler] (with no arguments) doesn't exist, does it ?

apple-ihack-geek commented 7 years ago

Also, you're missing a ; on 67

@apple-ihack-geek OMG, Thanks. 56: it should be [self startSession] I fix it at #44
