resourcePath not working Xcode

问题

I have created a sqlite database containing data for my app, and dragged it into the supporting files group in Xcode.

When I try to access it using:

NSString *bundlePath = [[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:@"database.db"];

It does not read the file. However if I put in the full file path:

NSString *bundlePath = @"Users/xxxx/Apps/App/database.db";

The app works fine.

I printed out the file path from:

NSString *bundlePath = [[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:@"database.db"];

and it is:

/Users/xxx/Library/Application Support/iPhone Simulator/5.1/Applications/EE614EFA-BAF9-478E-xxxx-xxxx/App.app/database.db

Any ideas why?

回答1:

The best way to deal with paths is to let the API take care of the details about "appending" stuff to path strings.

NSString *path = [[NSBundle mainBundle] pathForResource:@"database" 
                                                 ofType:@"db"]; 

回答2:

NSString *path = [[NSBundle mainBundle] pathForResource:@"database" ofType:@".SQLite"];
