Reading and Writing files to the document's folder

[GreenApple]

Hi all,

Does anyone know how do I read and write files to the App's documents folder? I have a UIView as a canvas, and I need to save the entire content in the UIView, and be able to retrieve it later. It's like all the drawing app. So it needs to use the app's documents folder, not just saving current state.

I was pointed to look at NSFileManager class, unfortunately all the sample codes are MacOS X related, not for iOS.


Anyone could give me some pointers or show me around, I'll be very much appreciated.


Many thanks.

if (! [[NSFileManager defaultManager] fileExistsAtPath: dbFilePath]) {
//NSLog(@"didn't find db, need to copy");
NSString *backupDbPath = [[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:@"Task.db"];
if (backupDbPath == nil) {
// couldn't find backup db to copy, bail
return NO;
} else {
BOOL copiedBackupDb = [[NSFileManager defaultManager]
copyItemAtPath:backupDbPath
toPath:dbFilePath
error:nil];

// copying backup db failed, bail
