iOS Where Is Textual Data Saved?

[Darkroom]

for apps that allow textual input (like word processors), where is that data saved on the iPhone? app-specific database? .plist file? are there any simple tutorials that i can use to calm my curiosity?

im not terribly new to development, but i know next to nothing about iPod dev.



*i know this is prob an elementary question, but i've never actually used an iPhone/iPod Touch before... so you can understand where my curiosity is coming from.

This is right out of an apple example program:

NSFileManager *fileManager = [NSFileManager defaultManager];
NSError *error;
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
self.pathToUserCopyOfDatabasePlist = [documentsDirectory stringByAppendingPathComponent"database.plist"];
if ([fileManager fileExistsAtPathathToUserCopyOfDatabasePlist] == NO) {
NSString *pathToDefaultPlist = [[NSBundle mainBundle] pathForResource"database" ofType"plist"];
if ([fileManager copyItemAtPathathToDefaultPlist toPathathToUserCopyOfDatabasePlist error:&error] == NO) {
NSAssert1(0, @"Failed to copy data with error message '%@'.", [error localizedDescription]);
}
}

It gets saved in the user's documents directory.

ok... so it's saved as the app's .plist in the iPhone's documents directory? even if there are hundreds/thousands of user entered strings, they all just get saved to the app's .plist?

It's not automatic. It's up to your app to choose where it wants to save its data. Read the OS programming guide. You can save it in a file of whatever format you like. You can save it on a web server in China. It's up to you to decide.
