iphone - 关闭uiimagepickerviewcontroller后如何使状态栏重新出现

当我模态显示uiimagepickerviewcontroller时，我在应用程序中隐藏状态栏。

[[UIApplication sharedApplication] setStatusBarHidden:YES withAnimation:UIStatusBarAnimationFade];

在回调方法中:

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info

我执行以下方法:

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

致电之前:

[picker dismissViewControllerAnimated:YES completion:^() {}];

我尝试在完成块中“显示”状态栏无济于事。关闭uiimagepickerviewcontroller后，如何使状态栏重新出现？

最佳答案

尝试将其放回视图控制器解雇完成处理程序中:

[picker dismissViewControllerAnimated:YES completion:^(BOOL done){
    [[UIApplication sharedApplication] setStatusBarHidden:NO withAnimation:UIStatusBarAnimationNone];
    [[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleBlackTranslucent animated:YES];
}];

尽管这很奇怪，但没有任何理由说明为什么这种方法无法奏效。
