提出的UIImagePickerController相机可以拍照或取消

Question

我有UIImagePickerController打开一个摄像头，如下面的示例代码所示。

UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init];
imagePicker.sourceType = UIImagePickerControllerSourceTypeCamera;
imagePicker.allowsEditing = YES;
imagePicker.delegate = self;

imagePicker.modalPresentationStyle = UIModalPresentationPageSheet;

[self presentViewController:imagePicker
                   animated:YES
                 completion:NULL];

我的问题：当我出示相机时，相机显示，但我无法拍照或点按取消。即使是翻盖相机图标也没有响应。 发生在iOS 8以下版本的iPad上。

Answer 1

我尝试了你的代码，并在iPad 2上运行iOs7.1.2 你可能会尝试使用setter，这就是我在做的事情

UIImagePickerController *picker = [[UIImagePickerController alloc] init];
[picker setAllowsEditing:YES];
if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera])
{
    [picker setSourceType:UIImagePickerControllerSourceTypeCamera];
    [picker setModalPresentationStyle:UIModalPresentationPageSheet]; 
}
else
    [picker setSourceType:UIImagePickerControllerSourceTypePhotoLibrary];
[picker setDelegate:self];
[self presentViewController:picker animated:YES completion:nil];
