Question

I have a plist which I am changing:

NSString *finalPath = [path stringByAppendingPathComponent:@"KeyFrameFileByMovie.plist"];
NSMutableDictionary *keyFrameFileByMovie = [[NSMutableDictionary alloc] initWithContentsOfFile:finalPath];
[keyFrameFileByMovie setValue:keyFrameName forKey:movieName];
BOOL isOk = [keyFrameFileByMovie writeToFile:finalPath atomically:YES];

On the simulator isOk is 1
on the device isOK is 0

I don’t think it is a case sensative issue, because I have a getting code that works:

NSString *finalPath = [path stringByAppendingPathComponent:@"KeyFrameFileByMovie.plist"];<br>
NSDictionary *plistData =[[NSDictionary dictionaryWithContentsOfFile:finalPath] retain];

Why is does writeToFile fail on the device?

Answer 1

iPhone application has very strict directory structure. Unfortunately the permissions on the device vs simulator are diferent. So the only problem here can be that you are not saving in the Documents directory but in the MainBundle dir.

In the example above, what is the path value?
