Refresh/reload textview from database | Button Tapped Function

Question

I have declare the textview outlet:

@IBOutlet weak var messageView: UITextView!

I have created the interface action, and place the logic:

@IBAction func refreshTextViewTapped(sender: UIButton) {

// logic

}

Reload/update textview with new content.

Answer 1

doesn't the setText function automatically update the textview? What would you need a reload function to do if the text is already being updated?

- (void)viewDidLoad()
{
    setMyTextView();

    // create the button that calls your function to update the text view
    UIButton *myButton = [[UIButton alloc] initWithFrame:CGRectMake(0, 0, 100, 44);
    [myButton addTarget:self action:@selector(setMyTextView) forControlEvents:UIControlEventTouchUpInside];
    [self.view addSubview:myButton];
}

- (void)setMyTextView()
{
    NSString *myText = // value that is returned from the database query;
    [self.myTextView setText:myText];
}
