Saving data
-
Hey all,
How do I save data into a file? I have 2 books on Cocoa programming
(Cocoa Programming with Mac OS X, and Learning Cocoa with Objective C)
and they only show you how to do it using a Cocoa Document Application.
Is there a way to do it with a normal single window/nib file Cocoa
Application?
Thanks,
Joseph

What are you trying to save? For most of the Foundation storage classes
(NSArray, NSDictionary, even NSNumber), you can just use writeToFile:
atomically:. For everything else, there's NSArchiver. You may also want to
look at NSPropertyListSerialization.

Joseph,
simply do the following:
- (void)saveDataIntoFile:(NSString*)pFilePath
{
char * pBytes;
unsigned length;
length = DATAFILE_LENGTH; //custom define
pBytes = malloc(length);
// store your data to pBytes here
{ // Save to file
NSData * pSaveData = [NSData dataWithBytes:pBytes length:length];
[pSaveData writeToFile:pFilePath atomically:FALSE];
}
free(pBytes);
}
Hope that helps!
