iOS 10错误[access]< private>使用UIImagePickerController时 [英] iOS 10 error [access] <private> when using UIImagePickerController

问题描述

我正在使用XCode 8并使用iOS 10.2 Beta进行测试。

I am using XCode 8 and testing with iOS 10.2 Beta.

我已将Photos，PhotosUI和MobileCoreServices框架添加到项目中。

I have added the Photos, PhotosUI and MobileCoreServices frameworks to project.

非常简单的代码：

#import <Photos/Photos.h>
#import <PhotosUI/PhotosUI.h>
#import <MobileCoreServices/MobileCoreServices.h>

@interface ViewController : UIViewController <UIImagePickerControllerDelegate, UINavigationControllerDelegate, PHLivePhotoViewDelegate>

@property (strong, nonatomic) IBOutlet UIImageView *imageview;

@end

和实施：

- (IBAction)grab:(UIButton *)sender{
    UIImagePickerController *picker = [[UIImagePickerController alloc]init];
    picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
    picker.allowsEditing = NO;
    picker.delegate = self;

    // make sure we include Live Photos (otherwise we'll only get UIImages)
    NSArray *mediaTypes = @[(NSString *)kUTTypeImage, (NSString *)kUTTypeLivePhoto];
    picker.mediaTypes = mediaTypes;

    // bring up the picker
    [self presentViewController:picker animated:YES completion:nil];
}

点击按钮时，应用程序崩溃时出现非常无用的错误：

As soon as I tap the button, the app crashes with very useless error:

[access]< private>

而已。没有别的。

使用break语句，应用程序似乎在presentViewController崩溃。

Using break statements, the app seems to crash at "presentViewController".

这是一个全新的应用程序，除了抓取按钮，我在UI中没有任何其他内容。

This is a brand new app and I don't have anything else in the UI other than the grab button.

此外，在iOS 9.3上测试，这很好用。我错过了iOS 10中可能会更改的内容吗？

Also, testing on iOS 9.3, this works fine. Am I missing something which might be changed in iOS 10?

推荐答案

您可能需要将NSPhotoLibraryUsageDescription放入plist中。
赞

You may need to put the NSPhotoLibraryUsageDescription in your plist. Like

<key>NSPhotoLibraryUsageDescription</key>
<string>$(PRODUCT_NAME) uses photos</string>

检查所有使用说明在其他地方。
