看一看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); 
}
