檢查照片庫的授權狀態

Question

有沒有辦法在新的iOS 6授權方案下檢查您的應用對設備照片庫的授權級別？

換句話說，是否有相當於ABAddressBookGetAuthorizationStatus而不是照片庫？

Answer 1

ALAuthorizationStatus status = [ALAssetsLibrary authorizationStatus]; 

爲ALAuthorizationStatus該文檔顯示可能的值。此API僅適用於iOS 6.0或更高版本。

Answer 2

我用這敷設渠道：

[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. 
    }];
