Databases have a problem!

When added to the sqlite database program which runs on mac above can be successfully copied to the Document directory, but I go online when the iphone is not copied, it has encountered this problem? Can help solve it? / / NSString * localDBPath = [[NSHomeDirectory () stringByAppendingPathComponent: @ "Documents"] stringByAppendingPathComponent: @ "Golf.sqlite3"];
/ / If ([[NSFileManager defaultManager] fileExistsAtPath: localDBPath]!) {
/ / NSString * bundleDBPath = [[NSBundle mainBundle] pathForResource: @ "Golf" ofType: @ "sqlite3"];
/ / [[NSFileManager defaultManager] copyItemAtPath: bundleDBPath toPath: localDBPath error: nil];
/ /}

In fact, I would like to know how you say no to replicate the success of the test?
You again with if ([[NSFileManager defaultManager] fileExistsAtPath: localDBPath]!) Judgment?

The test is not successful, I mean that you can call the above data after copying mac, iphone above but how to do so? ? ? The above code is also that you gave me, but it runs above the mac! iphone not, with no need if ([[NSFileManager defaultManager] fileExistsAtPath: localDBPath]!) phrase seems to not work!
