UIImagePickerController 照片被导航栏遮挡

UIImagePickerController 在iOS11中调起相册时 照片被导航栏遮挡，添加 translucent = NO

UIImagePickerController*imagePicker=[[UIImagePickerController alloc]init];

imagePicker.sourceType=UIImagePickerControllerSourceTypePhotoLibrary;

imagePicker.delegate=self;imagePicker.navigationBar.translucent=NO;[self presentViewController:imagePicker animated:YES completion:nil];

即可解决，但是在iOS13中设置以上发现没有效果，在自定义的navigationController 中添加

[[UINavigationBar appearance]setTranslucent:NO]; 解决。
