UIImagePickerController被解散时，只在iOS 6.0中将视图推到20像素

编辑 ：我正在使用UIStoryBoard 。

我有这样的presented ：

 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dissmissed

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

现在view如下图所示：

编辑 ：视图获取推到20px时dissassed。

Answer 1

原因是我设置的view controller previous view protrait mode因为它previous view是在landscape mode 。

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

每当imagepicker dissmiss被called它moved到original position mentioned 。

现在在structure改变了orientation 而没有设置self.view框架在外面 solved我的problem 。

如果该视图的蓝色部分是自定义UIView那么你应该检查该视图的自动resize的掩码。 你会发现这个问题。

Answer 3

我有类似的问题，在我的情况下，20像素是状态栏的高度。 因此，尝试在显示imagePicker之前将状态栏可见性设置为NO，并在完成时（在委托方法中）将YES设置为YES。

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:^{ }]; }

我有类似的问题在iOS 8.2。 使用UIImagePickerController拾取video后，帧增加了20px，视图控制器的顶部区域看起来不错，但底部被切断。 解决scheme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]; }); }
