iOS应用程式相机存取遭拒iOS 9.1（黑色画面）** [已解决] ** [英] iOS app camera access denied iOS 9.1(black screen) **[solved]**

问题描述

  if（[UIImagePickerController isSourceTypeAvailable：UIImagePickerControllerSourceTypeCamera ]）
 {
 UIImagePickerController * picker = [[UIImagePickerController alloc] init]; 
 picker.delegate = self; 
 picker.allowsEditing = YES; 
 picker.sourceType = UIImagePickerControllerSourceTypeCamera; 
 if（isIOS8SystemVersion）
 {
 [[NSOperationQueue mainQueue] addOperationWithBlock：^ {
 [self presentViewController：picker animated：YES completion：NULL] 
}]; 
} 
 else 
 {
 [self presentViewController：picker animated：YES completion：NULL]; 
} 
} 
  

此代码适用于我的其他应用程序。这个应用程序，它不是要求相机权限或显示在设置 - >隐私 - >相机。

应用程式会提示您使用位置。不会显示相机或相片的任何内容。

解决方案

我已经准确地使用了相机代码同一问题几天，

尝试这解决我的问题，确保有一个值

在我的情况下，它是空的，因为它没有工作。

让我知道它是否对您有帮助。

I want to access camera in my app.I am trying the following code.

  if ([UIImagePickerController isSourceTypeAvailable: UIImagePickerControllerSourceTypeCamera])
            {
                UIImagePickerController *picker = [[UIImagePickerController alloc] init];
                picker.delegate = self;
                picker.allowsEditing = YES;
                picker.sourceType = UIImagePickerControllerSourceTypeCamera;
                if(isIOS8SystemVersion)
                {
                    [[NSOperationQueue mainQueue] addOperationWithBlock:^{
                        [self presentViewController:picker animated:YES completion:NULL];
                    }];
                }
                else
                {
                    [self presentViewController:picker animated:YES completion:NULL];
                }
            }

This code works on my other app perfectly.But in this app,it is not asking camera permissions or showing it in the settings->privacy->camera.

The app prompts to use the location.But not showing anything for the camera or photos.

The black screen appears and I can't take the picture if I directly use the camera code without the condition check.

解决方案

I had the exactly same issue for couple of days,

Try this its solved my problem, make sure that there is a value

(Application name as string) in your info.plist > "Bundle display name".

In my case it was empty and because of that it didn't work.

let me know if it helped you.
