Answer 1

Create function that is called on a button click, test if the user has hit enter, or test if the user has removed focus from the UITextView:

-(IBAction)saveText
{

Get the path to the file you want to create:

NSArray *documentPaths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); 
NSString *documentsDirectory = [documentPaths objectAtIndex:0];
NSString *documentTXTPath = [documentsDirectory stringByAppendingPathComponent:@"savedText.txt"];

Get the text from the UITextView (replace textView with the name of your UITextView):

NSString *savedString = textView.text;

Write the string to the file:

    [savedString writeToFile:documentTXTPath atomically:YES];
}
