iphone SDK:Can write data to plist on Simulator but can't do same thing at Device?

Question

Why I can write information to plist on simulator

But can\'t do this on real iphone/ipod device ????

Is there exist an absolute path to put a .plist file in

Answer 1

You can only write to your application's sandbox directory. Below is a function that will return the path to the Documents folder for you app.

- (NSString *)applicationDocumentsDirectory
{
    return [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) lastObject];
}
