Question

我试图在屏幕上显示完整的图像，通过推动模态视图，使用完整的图像，我设法做到这一点没有问题，但由于某种原因我无法隐藏模态上的状态栏，我我在集合视图的didSelectItemAtIndexPath中呈现模态，我试图隐藏状态栏，然后调用presentViewController，这里是代码：

-(void)collectionView:(UICollectionView *)collectionView didSelectItemAtIndexPath:(NSIndexPath *)indexPath {

    NSArray *infoPhoto = self.imagesFromCD[indexPath.row];

   // NSLog(@"Info photos = %@", infoPhoto);
    NSString *imageName = [[self.imagesFromCD valueForKey:@"imgNameCD"]objectAtIndex:indexPath.row];
    UIImage *imageToPass = [self getImageFromDocuments:imageName];

    displayImageViewController *displayVC = [[displayImageViewController alloc]init]; 
    displayVC.modalPresentationStyle = UIModalPresentationCustom;
    displayVC.transitioningDelegate = self;
    displayVC.foto = infoPhoto;
    displayVC.imageToDisplay = imageToPass;

    UIApplication *myapp = [UIApplication sharedApplication];
    [myapp setStatusBarHidden:YES withAnimation:YES]; // Heres where the bar should be hidden.
    [self presentViewController:displayVC animated:YES completion:nil];
}

我还尝试添加：

-(BOOL)prefersStatusBarHidden {
    return YES;
}

在Modal .m文件中，但什么也没发生。

首先在您的info.plist基于视图控制器的状态栏中设置状态栏等于否，而不是在下面使用状态栏隐藏与否：

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

[[UIApplication sharedApplication] setStatusBarHidden:NO
                                        withAnimation:UIStatusBarAnimationFade];

iOS在模态视图上隐藏状态栏
