Question

我可以暂时从我的应用中的照片库中选择一张图片，但出于某种原因，当用户尝试选择图片时，我现在正在崩溃（EXC_BAD_ACCESS）过去常常。

我尝试将所有隐私条目添加为测试而没有运气。寻找修复，我注意到我有一个类似的日志，没有设置隐私密钥，但我在信息plist中有正确的条目，我有一段时间，我甚至获得了许可警报当试图打开选择器时。这里我的信息plist条目：

我所拥有的筹码如下：

在调试期间以及Testflight buids中，模拟器和设备都会发生崩溃，但有趣的是，AppStore上可用的应用程序运行良好。

Answer 1

现在正在努力......

我有以下NSObject扩展名，我找到了将类名称作为字符串的地方：

extension NSObject {

    public class var name: String {
        return NSStringFromClass(self).components(separatedBy: ".").last!
    }

    public var name: String {
        return NSStringFromClass(type(of: self)).components(separatedBy: ".").last!
    }
}

更改实例var的名称使照片库再次运行。以防万一我重命名class var，但实例var就是问题。

希望这有助于某人。

即使设置了正确的隐私密钥，UIImagePickerController也会崩溃
