Both time-dependent and time-integrated $CP$ asymmetries are calculated, without special approximations, to meet various possible measurements at symmetric and asymmetric $e^{+}e^{-}$ $B$ factories. We show two ways to distinguish between direct and indirect $CP$-violating effects in the $CP$-eigenstate channels such as $B^{0}_{d}/\\bar{B}^{0}_{d}\\rightarrow \\pi^{+}\\pi^{-}$ and $\\pi^{0} K_{S}$.
