程序启动crash, `fireTimer`

报错文件 NSTimer+CleanTimer.m

错误定位代码

- (void)fireTimer{
    if (!self.target) {
        [self.timer invalidate];
        self.timer = nil;
        handleCrashException(JJExceptionGuardNSTimer,[NSString stringWithFormat:@"Need invalidate timer from target:%@ method:%@",self.targetClassName,self.targetMethodName]);
        return;
    }
    if ([self.target respondsToSelector:self.selector]) {
        // Fix swift case, the parent class is SwiftObject, did not invoke the methodSignatureForSelector method
        // https://github.com/jezzmemo/JJException/issues/123
        ((void(*)(id, SEL, NSTimer*))objc_msgSend)(self.target, self.selector, _timer);
    }
}
