停用后，UIImagePickerController仅在iOS 6.0中将视图向上推20像素

Question

编辑 ：我正在使用UIStoryBoard 。

我presented这样的：

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

imagePicker.delegate = self;

imagePicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary; //| UIImagePickerControllerSourceTypeSavedPhotosAlbum ;
imagePicker.mediaTypes = [NSArray arrayWithObjects:(NSString *) kUTTypeImage,nil];

if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypePhotoLibrary])
{
    if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone)
    {
        imagePicker.allowsEditing = YES;
        [self.navigationController presentViewController:imagePicker animated:YES completion:^{

        }];  
    }
}

现在，当被dissmissed

-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
   UIImage *image = info[UIImagePickerControllerEditedImage];
    NSLog(@"Image : %@",image);
    [self dismissViewControllerAnimated:YES completion:^{
    }];
}

现在view变成这样在如图fiqure ：

编辑 ：视图被解雇时被推高至20px。

编辑 ：这仅在iOS 6.0中

Answer 1

原因是我将 view controller 框架设置为protrait mode因为它previous view处于landscape mode 。

self.view.bounds = CGRectMake(0,0,...,...);

每当imagepicker dissmiss得到了called它moved到original position如mentioned 。

现在改变了orientation structure而无需设置self.view框架从外部 solved我的problem 。

Answer 2

如果该视图的蓝色部分是自定义UIView ，则应检查该视图的自动调整大小蒙版。 您会发现问题。

Answer 3

我有类似的问题，在我的情况下，状态栏的高度为20像素。 因此，尝试将状态栏可见性设置为NO，然后再显示imagePicker，然后在完成时显示YES（在委托方法中）。

像这样的东西：

[UIApplication sharedApplication].statusBarHidden = YES;
[self.navigationController presentViewController:imagePicker animated:YES completion:^{
        }];


-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
   // ... your code here
   [UIApplication sharedApplication].statusBarHidden = NO;
   [self dismissViewControllerAnimated:YES completion:^{
    }];
}

Answer 4

我在iOS 8.2上遇到过类似的问题。 使用UIImagePickerController拾取视频后，帧增加20px，视图控制器的顶部区域看起来不错，但底部被切除了。 解决方案是：

-(void)openPicker {}
    [[UIApplication sharedApplication] setStatusBarHidden:YES withAnimation:UIStatusBarAnimationSlide];
    UIImagePickerController *picker = [[UIImagePickerController alloc] init];
    //configure image picker here
    [self presentViewController:picker animated:YES completion:NULL];
}

-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
    [NSTimer scheduledTimerWithTimeInterval:0.1 target:self selector:@selector(showStatusBar) userInfo:nil repeats:NO];
    [picker dismissViewControllerAnimated:YES completion:NULL];
}

-(void)showStatusBar {
    dispatch_async(dispatch_get_main_queue(), ^{
        [[UIApplication sharedApplication] setStatusBarHidden:NO withAnimation:UIStatusBarAnimationSlide];
    });
}
