對於每個應用更新,我想完全擦除我的整個Core Data數據庫,然後重新設置它。我沒有成功這樣做。我嘗試了各種各樣的東西,這似乎是最接近我來的。我發現了幾個SO帖子,但沒有一個解決方案適用於我的目的。MagicalRecord:刪除整個數據並重新設置核心數據堆棧
我使用的是MagicalRecord
,它提供了幾種簡短的手段來獲取各種對象。這裏是我的代碼:
if ([[[NSUserDefaults standardUserDefaults] objectForKey:@"buildVersion"] intValue] < [[[[NSBundle mainBundle] infoDictionary] objectForKey:@"CFBundleVersion"] intValue]) {
NSPersistentStore *store = [NSPersistentStore defaultPersistentStore];
NSError *error;
NSURL *storeURL = [NSPersistentStore defaultLocalStoreUrl];
NSPersistentStoreCoordinator *storeCoordinator = [NSPersistentStoreCoordinator defaultStoreCoordinator];
[storeCoordinator removePersistentStore:store error:&error];
[[NSFileManager defaultManager] removeItemAtPath:storeURL.path error:&error];
[[NSUserDefaults standardUserDefaults] setObject:[[[NSBundle mainBundle] infoDictionary] objectForKey:@"CFBundleVersion"] forKey:@"buildVersion"];
}
[MagicalRecord setupCoreDataStack];
