使用sqlite时遇到的错误 read-only

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];
