查看stringWithContentsOfFile:encoding:error:和writeToFile:atomically:encoding:error:

NSString *documentsDirectory = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) lastObject];
NSString *path = [documentsDirectory stringByAppendingPathComponent:@"myfile.plist"];
NSError *error = nil;

// read from plist:
NSString *text = [NSString stringWithContentsOfFile:path encoding:NSUTF8StringEncoding error:&error];
if (!text) {
    NSLog(@"Error reading - %@", error);
}
textView.text = text;

// save to plist:
NSString *text = textView.text
if (![text writeToFile:path atomically:YES encoding:NSUTF8StringEncoding error:&error]) {
    NSLog(@"Error saving - %@", error);
}
