ios - Unity Prime31 照片提示在 iOS 10 和 XCode 8 上崩溃

Question

调用 EtceteraBinding.promptForPhoto 导致 iOS 10 立即崩溃。

public void TakePhotoTapped() {

    #if UNITY_IOS
    EtceteraBinding.promptForPhoto(0.2f, PhotoPromptType.Camera, 0.8f, true);
    #endif

}

Xcode 吐出这个日志。它看起来确实像某种权限问题？请帮忙。

这与新的 iOS 10 隐私设置要求有关。您必须提前声明对私有(private)数据的任何访问权限，否则您的应用程序将崩溃。

您可以将使用 key 与目的字符串一起添加到应用程序的 Info.plist，或者添加一个脚本，在 Unity 中为您的所有构建执行此操作。

Xcode Info.plist 选项卡:


因此，对于每个框架，您必须声明它的用途并输入显示给用户的字符串消息。

您还可以在 Assets/Editor 文件夹中添加后处理脚本，在其中声明使用的所有功能 - 这将自动将它们添加到 Info.plist:

using UnityEngine;
using UnityEditor;
using System.Collections;
using UnityEditor.Callbacks;
using System.Collections;
using System.IO;
using UnityEditor.iOS.Xcode;


public class ChangeIOSplistFile : MonoBehaviour {

    [PostProcessBuild]
    public static void ChangeXcodePlist(BuildTarget buildTarget, string pathToBuiltProject) {

        if (buildTarget == BuildTarget.iOS) {

            // Get plist
            string plistPath = pathToBuiltProject + "/Info.plist";
            PlistDocument plist = new PlistDocument();
            plist.ReadFromString(File.ReadAllText(plistPath));

            // Get root
            PlistElementDict rootDict = plist.root;
            var cameraKey = "NSCameraUsageDescription";
            rootDict.CreateDict (cameraKey);
            rootDict.SetString (cameraKey, "Enter your description here.");

            var galleryKey = "NSPhotoLibraryUsageDescription";
            rootDict.CreateDict (galleryKey);

            rootDict.SetString (galleryKey, "Enter your description here.");

            // Write to file
            File.WriteAllText(plistPath, plist.WriteToString());
        }
    }
}
