Question

我的项目中有以下代码，可以通过“ MPMediaPickerControllerDelegate”选择音频文件。当运行下面的代码时，第一次提示用户授予权限。如果用户拒绝加载，则选择器将自动失败。

如果用户最初拒绝后返回，是否可以提示用户授予权限？

我想知道这是否是一个错误。有什么方法可以检测到MPMediaPickerControllerDelegate的许可，以便我们决定是否显示音频。

下面是我的代码：

您必须先检查授权许可，然后如果授权状态许可为authorized，然后运行代码。如果不是notDetermined，请寻求许可。如果是denied，则显示“警告”，要求用户进入“设置”并启用此权限。

MPMediaLibrary.requestAuthorization({(newPermissionStatus: MPMediaLibraryAuthorizationStatus) in  
    // This code will be called after the user allows or denies your app permission.  
    switch (permissionStatus) {  
        case MPMediaLibraryAuthorizationStatus.authorized:  
             print("permission status is authorized")  
        case MPMediaLibraryAuthorizationStatus.notDetermined:  
             print("permission status is not determined")  
          MPMediaLibrary.requestAuthorization(MPMediaLibraryAuthorizationStatus -> permissionStatus)  
        case MPMediaLibraryAuthorizationStatus.denied:  
             print("permission status is denied")  
        case MPMediaLibraryAuthorizationStatus.restricted:  
             print("permission status is restricted")  
    }  
})
