相机UIImagePickerController在设备ios8中显示黑屏

Question

我尝试下面的代码来通过相机捕获图像。此代码在iPhone 6下方的所有设备中都能正常运行 此代码在iPHone6和iPhone6 +中不起作用。它显示黑屏。

enter code here

 (void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex
{
    UIImagePickerController *picker = [[UIImagePickerController alloc] init];
    picker.delegate = self;
    picker.allowsEditing = YES;

    switch (buttonIndex)
    {
        case 0: NSLog(@"Photo Butten Clicked");
            picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
            [App_Delegate.window.rootViewController presentViewController:picker animated:YES completion:nil];
            //            [self presentViewController:picker animated:YES completion:NULL];
            break;

        case 1: NSLog(@"Camera Butten Clicked");
            picker.sourceType = UIImagePickerControllerSourceTypeCamera;
             [App_Delegate.window.rootViewController presentViewController:picker animated:YES completion:nil];
            // [self presentViewController:picker animated:YES completion:NULL];
            break;

        default:
            break;
    }
}

Answer 1

您只需更改设备的设置

请按照以下步骤

1）转到设备设置。

2）在设置列表中找到您的应用程序。

3）并为您的应用程序提供相机访问权限（允许＆＃34;应用程序名称＆＃34;访问）。

Answer 2

我得到了解决方案。我只是替换 下面的代码

[App_Delegate.window.rootViewController 
        presentViewController:picker 
        animated:YES 
        completion:nil];

使用此代码

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