Adding SQLITE_OPEN_URI flag

[marcelofabri]

I've updated my SQLite version (as now I need to use SQLCipher), but I was surprised that FMDatabaseQueue's inits and databaseQueueWithPath: started returning nil, because sqlite3_open_v2 started returning SQLITE_CANTOPEN.

Adding SQLITE_OPEN_URI to the flags resolved the issue. I know that I can use initWithPath:flags:, but I think most people won't realize that this is needed.

So you're adding something like file:/// to the front of your database path?

I'm using absoluteString on an NSURL, which does return file:///.

Obviously, if you used path rather than absoluteString, this change would be unnecessary.

I do not think it is correct to make the path rendition of this method accept a URL string. If we wanted one that took NSURL, that's a different matter. But methods that take paths generally (never?) accept URL strings and I don't think this should either.

@robertmryan I would agree with you if this never worked. However, it was working before updating SQLite and this would be more a convenience.

But, as you said, FMDatabase clearly states that it needs a file system path, so I'll update my code to use path.
