在模拟器上运行没有问题;
在真机上报如下错误: Attempt to add read-only file at path file://localhost/var/mobile/Applications/A80208B7-36C8-4CD0-94D9-E3EC57BDA4D6/BookingMeals.app/ShopCar.sqlite read/write. Adding it read-only instead. This will be a hard error in the future; you must specify the NSReadOnlyPersistentStoreOption. 问题已经解决,多谢各位,特别是3楼。 resources中的文件全为只读文件,因此需要将sqlite文件拷贝到document目录中使用。 代码如下: NSString *path =[[NSBundle mainBundle] pathForResource:@"数据库文件名" ofType:nil]; NSArray *paths = NSSearchPathForDirectoriesInDomains(NSCachesDirectory,NSUserDomainMask,YES); NSString *documentsDirectory = [paths objectAtIndex:0]; NSString *writableDBPath = [documentsDirectory stringByAppendingPathComponent:@"ShopCar.sqlite"]; [[NSFileManager defaultManager]copyItemAtPath:path toPath:writableDBPath error:nil]; NSURL *url = [NSURL fileURLWithPath:writableDBPath];
