Question

How would I make the source text of a UITextView change whenever I press different buttons?
Thanks.

Answer 1

To change the text of a UITextView, set its text property:

textView.text = @"your text here";

You can call this from within a button’s selector like so:

UIButton *yourButton = [UIButton buttonWithType:UIButtonTypeRoundedRect];
[yourButton setTitle:@"click to change textview's text" forState:UIControlStateNormal];
[yourButton addTarget:self action:@selector(buttonClicked:) forControlEvents:UIControlEventTouchUpInside];

...

- (void)buttonClicked:(id)sender {

    textView.text = @"your text";
}
