ios调用相机之后状态栏消失

Apparently, in addition to setting the status bar to not be hidden, you also have to reset its style after the camera view makes it disappear. Try this:

[[UIApplication sharedApplication] setStatusBarHidden:NO animated:NO];
[[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleBlackTranslucent animated:YES];
