這段代碼是當(dāng)年苦逼了一下自己研究出來豹储，好久沒用到了，近來又使用淘这，發(fā)現(xiàn)差點忘了剥扣。呵呵巩剖！~貼出來吧。做個記憶钠怯。
for (UIViewController *controller in self.navigationController.viewControllers) {
??????????? if ([controller isKindOfClass:[要返回的類名 class]]) {
??????????????? [self.navigationController popToViewController:controller animated:YES];
??????????? }
?}
