Question

有没有办法根据新的iOS 6授权方案检查应用程序的授权级别到设备的照片库？

换句话说，ABAddressBookGetAuthorizationStatus是否存在与照片库相反的等价物？

Answer 1

ALAuthorizationStatus status = [ALAssetsLibrary authorizationStatus];

ALAuthorizationStatus的文档显示了可能的值。此API仅适用于iOS 6.0或更高版本。

Answer 2

我正在使用这个结构：

[assetsLibrary enumerateGroupsWithTypes:ALAssetsGroupAll usingBlock:^(ALAssetsGroup *group, BOOL *stop) {
        if (*stop) {
            return ;
        }
// TODO : access granted
    *stop = TRUE;
    } failureBlock:^(NSError *error) {
        // TODO: User denied access. Tell them we can't do anything.
    }];

Answer 3

对于Swift中的PHPhotoLibrary，您应该获得PHAuthorizationStatus的值：

    let authorizationStatus = PHPhotoLibrary.authorizationStatus()

返回值为：

public enum PHAuthorizationStatus : Int {  

    case notDetermined // User has not yet made a choice with regards to this application

    case restricted // This application is not authorized to access photo data.

// The user cannot change this application’s status, possibly due to active restrictions
//   such as parental controls being in place.
    case denied // User has explicitly denied this application access to photos data.

    case authorized // User has authorized this application to access photos data.
}
